Initial Design Concepts

Monday, 19 November 12


DevelopmentAesthetics- squaring up Aesthetics- The Shard

When i first

looked at my design that i

plan on creating, and more importantly the aesthetics of the design, i saw the idea as a very soft

style with the use of all the smooth curves and the general roundness of the design. From here however i did say in my initial specification it would stand out in a modernism

room, and I'm not sure the level that it is at is striking enough to the eye. So

clearly i had to change something. So what i did was to start sharpening and

edging of my design to, almost make my design more viscous to the eye. I started

with a side profile of the design and added now views and details to give

me an idea of what i was working towards, and clearly from the

results(left) the design is certainly more striking with

not one curved edge and pointed edges as

three separate locations. From

what i have changed from the design i feel it has improved it, not only to

follow my specification more throughly but it

also looks much more attractive, and this is

what i wanted to achieve.

From the start i always wanted my design to be inspired somewhat by architecture and the shapes that are created in the real world, while the initial ‘squaring up’of the design has helped improved my vision of what my design would be like, i would want to also used a certain case study to almost use as a direct link to another aesthetic change. The shard, which is near complete in London has always interested me due to its pyramidal shape and stunning angles it can

be seen from, and as this is what i want my design to be like, i plan to use some shapes and visual aspects of the shard to help my design. The first part of this structure that interests me would be the tip of the shard(left). I have taken construction images and zoomed closer to see the detail and clearly from the images there is the steel top which gives a very blade like feature and gives a certain danger to the design, i will probably use this feature however the construction methods will have to fit in for me to incorporate this. Secondly is the open space between the struts in the building itself,

using this on my design would give it a raw and almost unfinished edge just like a sculpture would have and this could be done with the the use of a clear material



DevelopmentConstruction- Initial Structure Construction- Bolts and Screws

Moving on from the previous idea of the initial structure, rather that the

use of adhesives all over my design which would be mostly

weak and a long process, i would prefer to use bolts and

screws to create a more permeant joint to al the main

components of the design. There are many different types

of bolts i can use, for example a dome head bolt which would suit

well with my design as it would give a different dimension and a

different texture which may make my design more interesting if people

were to look closer at the more detailed parts. From the top right

image, and the top right of the picture the idea of a 90 degree steel joint which

would make complex

angles strongly fixed to

the design

Before i went any further into my development i wanted to

get my initial structure or the skeleton of my design completed so once the basics are done i can

focus on more of the details and parts that will

characterise my design.

From the left, my

design will have

straight edges all

over the design, this should help with joining processes

and also making it more sturdy and so the longevity can be extended. Another

point that i will make would be the idea of balance of the whole weight is to be put on a section of the wall, this means my design will either have to have a very

strong wall joint or have a relatively light weight with all the materials added together so that it will not fall of the wall at any point. But

due to my idea of the shard and different materials i want to

incorporate my wall design will have to be strong instead.



DevelopmentConstruction- Adhesives Construction- Wall Joint

Here i have created wall joint prototype to where i will be able to

place my design over, it may be simple but this means i can make it

incredibly strong from strong materials. To begin with i used one

sheet of a bendable material, here i used thick cardboard as it can be easily bent and shaped. Then cut

diagonals on the corners and then fold them over, if this process it

joined strongly, this means my design can be slotted into the wall joint and

can be permanent or temporary depending on

preferences. However it needs to be strong so i will make it in

sections and join them together using strong joins like a dove

tail. This will improve the longevity.

Although i did say adhesives were a longer and weaker process to joining larger sections of my design together it

doesn't mean that the smaller parts cant be joined using using the

different methods on the left. Adhesives such as cement, epoxy resin, PVA and glue gun glue sticks

can all be used differently on different materials to ensure the bet stick, i will most probably use all of these to give my design the best

overall quality. Glue gun glue sticks are very versatile and can used on

most materials however it may not be strong enough to hold non porous

materials. The strongest adhesive would be cement

however this would severely

weigh down the design and so i

will have to look for

different adhesive later on.



DevelopmentConstruction- Model Usability- Card Model

Continuing on from the development of construction i wanted to look more in detail about how my design will hold together when it is being build, and although this model is only a 2D representation using lightweight wood sticks, it gave me an idea where the stressful parts of the design are and where the key point are if it was to break at any point. A key area of this model was the parts joining the two curved segments of the design up, it was fairly flexible even when i had glued it down meaning this is the part where more industrial joints or adhesives were to be applied. Another section would be the top of the lower curve, this was also quite delicate but from here i know that a strut would go from he tip down through the design so this would not be a problem.

Next was a more solid model giving me a better understanding

of how someone may use my design and how i might change some aspects of the design so that people can find it more

natural to find and use some of the attachments that may be

added. To begin with, image top, this gives a perspective of how

someone may see my design(walking down stairs) and from this view i could clearly see

an opportunity to add the controls to may design while not spoiling the aesthetics, or even adding to the aesthetics. Using

the image on the left we can see i

have added small markings on the

card to show some places where

buttons can be placed, this gives a greater usability of

the product as they don't have to

walk directly in front of the

speaker to change volume, song etc... and so the sound

of the speakers will not be distorted by someone standing

in front of the speaker



DevelopmentUsability- AnthropometricsUsability- Ergonomics

Ergonomics are a key point in any design that has been carefully been planned out to work around a human, my design is no different as i

must take account of the different sizes to allow my user to use

my design comfortably and with ease. As my

design is wall mounted i will have to take

some measurements to

see how my design will be

placed(height on wall). An

average sized man is around

5,10 ft tall and a woman 5, 5 ft tall, this means my design will have to be around 6 ft of the ground

so that it is not in the way and keeps itself spaciously efficient but also so that all

people can reach the design and change certain aspects without issues or

problems so that my market does close up on the taller/shorter

Now anthropometrics focus on the sizes of the human body rather than making a product

fit around a human, i have already looked at the height of someone in

ergonomics and how they must be able

to use the design but

here i plan to change my

design so than everything is natural, one

quick example will

be the measure of someones

arm and then use this information so that the design is no wider than this (0.8 metres), this would improve my design as it would allow

people to reach around and make it more accessible from different angles

so that it is not constantly in the way .



DevelopmentUsability- Placing of SpeakerUsability- Card model con.

Again i am going to look at card model however this time i have

zoomed in more to see how someone may

approach, now for the bottom image the place

where the controls may go shows there is only room for

around 6 buttons, that gives enough for on/off,

volume and track change which is perfect, however on the other side i plan to

put on additions for the movement or removal of the speaker just to allow

easier accessibility

Placing my speaker in a suitable location in a typical modern home is very important to what i am trying to

achieve in the development, as i would like my design to be aesthetically enjoyed from most areas in the room and

also from the sound to be heard and finally for it to be specially efficient. On the is simple CAD(computer aided design) image of a typical room i have put on

green circled areas in and around the room which would be effective for all three of the criteria

however the red areas are places where they do not fit either one to none. Although every home is different it still will always have a key

vocal point in a room which anyone can exploit. This a key part that i will use and

always relate back to as this will ensure that my design is core to

a room



DevelopmentMaterials- ClayMaterials- Carbon Fibre

Like i have said before leading up to my development, i have always planned to use carbon

fibre in my design as it is a very stylish, modern material. And from the left i have tried out over some basic moulds to see how it works. Carbon fibre is done in layers with

releasing agents being applied first to the mould then we apply

around two layers of carbon weave with hardener, all one at a

time after allowing to dry. Although the process may be

simple, to do well it is very difficult this is why it was good for me to

practice with different things before i am to start make it fully. From this i will only use carbon

fibre on a small part of my design, so that room for error is

low and so it can be done well and to a high standard. To use this i may apply this material to the tip of the

design giving it a shine and

sharpness.

Another material that i wanted to experiment with was clay, although it may be a rather unorthodox material for such

designs for speakers etc,

the shapes and textures that

can be created would give my design

something special about it, but this all depends on

how practice went. On the left we have some images

of a test run on the whole

model, and the mess was

terrible with all of my mould covered in

dried clay and was fairly

awkward to get off. After

using clay i feel it is quite a

rough edgy material that probably will

not fit my design as it must take

time, patients and

lots of resources to make clay

attractive to the eye.



DevelopmentMaterials- Steel Rods Materials- Polishing Plaster

Using steel pure can be tricky however using steel rods for a design can be generally very easy and also look good if

the finishing of the material is done to a high standard. With this test i have got three lines of steel rod. The first one is

rough with no finishing it is ugly and very dirty to the

eye. The second has been sanded with course sand paper to technically give the rod a ‘grain’ which looks very edgy but also

quite clean. And finally the bottom two images have

had a full finish done in them which the use of

smaller grain sand paper followed by wet and dry

then moving onto buffering and then finally polishing.

Now this last process takes and long times and does give a good shine to the

steel rod, however it does just remind me of the KEF

Muon which is very clean and

sophisticated, on the other hand i would

like my design to be a little shaper so i will go with the

middle method of steel

finishing

I have never thought of using plaster before as for most times the quality of

finishing is not good enough for

nice designs, however after seeing what

polished plaster looks like when

done well it looks like something

that would work with my design.

For polishing plaster it is very simple all that

needs to be done is: sanding a steel

trowel this removes imperfections,

wiping trowel with tack cloth then rubbing in short

strokes with polish, wipe wall then wax

the wall. This process is very simple and

yet we can see from the images the finish

looks good on all different surfaces

however this is not regular to use on product especially speakers so i will

have to see what happens later in manufacture.



DevelopmentMaterials- Wire Materials- Aluminium sheet

I have used wire before and is excellent for finishing of designs giving it and extra

shine on a corner for giving a plain material some

texture, it is used in different parts of

architecture especially bridges making it perfectly

suited to my design, i will use wire however in

small moderation and only for

finishing touches

Aluminium sheet can be worked on in many ways but the most interesting method for

me is cold forging with a hammer, this

can give extraordinary shapes in the

metal and can also be

moulded around rough

shapes to create delicate textures like for example to the

bottom left. I will try and use aluminium in

my design where possible as it gives shine and it

finishes well.



DevelopmentMaterials- Clear/ Matt Acrylic Materials- Rubber

Earlier in my development i discussed the

influence of the shard on my design

and the the raw nature of

the open structure

interests me, well here in

materials I've looked at the use of either completely

clear acrylic, glossy acrylic or

lightly transparent acrylic. From here i

have placed all these materials up against

light, dark, wood, plastic backgrounds to see which would suit best, now

at the moment i will not be able to make my choice

till i see the structure later in my development however the clearly acrylic seems to look good

in all conditions.

I would like to use an elastomer in my design as it would

give a bit of variety as most of the

materials i will use are very cold and

un textured, however if i was to

use an elastomer for the buttons for the

base of my product it would definitely show more of a

quality in terms of a material that other

manufacturers of speakers like Bose, KEF and

Sony use all the time. Touch

sensitive can also be added

if available.



Specification Check

AestheticsWhen designing my speaker the aesthetics will be modern and fit the profile of KEF, it will be smooth and incorporate different materials giving it texture and character in the environment where it must be placed. I will use some composite materials in my design, it should show and emphasise sculptured design as well as a modern minimalist feel. Cost My design will be a medium to high priced design, with the joining, materials and overall quality being good. The finishes should be extremely high and a smooth texture should be consistent throughout the product. It should be attractive to KEF costumers.CostumerThe main users of my product (continued on page 11) will be a sophisticated character, male or female, very interested in functional artistic art and can be placed anywhere in their specified environment. My user can be of any range as long as the interest of music and art is apparent, and can afford the highly priced product. EnvironmentMy design will be placed in a very minimalist and modern home environment which can be distinguished wherever it is placed in that environment. I will be placing my design to conserve most space in an environment either on a wall, ceiling or shelfs. It should stand out but not to the scale where the design look ridiculous. SizeIn terms of the product, the design can be any type of size due to the amount of free space in the modernist environment, however i do not plan for my design to be as big as a design as the KEF Muon. It is to be big enough to capacitate the speakers and be recognised in the environment as a stylish piece of gear, that is the only specification for size.SafetyFor my design there will be minimal issues with the safety as it will be placed in an area which should not be in the way of the user. As before my design should look as if the design becomes one with the environment, and look aesthetically pleasing while doing so FunctionThere can be many functions and features for speakers however my design should be mainly aesthetically pleasing and functional in terms of the sound that will be produced. I may include some small smart features such as touch sensitive, but nothing to change the style of the design. MaterialsI will use materials mostly including plastics and wood, however to make my design unique i might use some smart materials such as carbon fibre....

Here i have met the specification due to the research in the sculptured and modern industry for example the

shard and geometric shapes.

While looking at materials such as carbon fibre and steel, this has gone along with this section

Due to the research in clay, ergonomics and anthropometrics, this has been met

When i had looked at the environment to see where my design will go, i have fulfilled this section

In ergonomics i have looked at how a human will fit around certain sizes, this has been met

Due to the research on the wall joint, the product should be safe and will not cause health issues

I have looked at aesthetics in detail and the development onto elastomers is key in meeting this section

I have used an abundance in materials like carbon fibre etc... However , i have not looked at the use of wood yet which is

something i will have to look at



Development Section 2

Materials- Finishing Off Materials

Materials- Joining

When i finally start to create my speaker design, the finish of the materials that i am using, such as steel, wood and carbon fibre all have a certain look and texture when i use them,

however as my design will be a sculpture style i want my design to be finished off to the highest degree. For wood (pictured right), i experimented with the use of wet and dry and

varnish. With wet and dry it gives the wood a certain crisp-ness to the wood making it sharper and more defined, however the wood

pictured far right i have added a varnish, this makes the wood a more complete colour and more consistent. From this i will only use

wet and dry as it resembles sculptures to a higher degree. With metals such as steel only finishes such as wet and dry, buffing and

polishing are available to me. However as before in my development i have looked at this therefore i will only use wet and

dry as it gives the material an edginess. And finally the use of plastics, now all acrylic sheets come pre-finished and so not much can be

done. I will however sand the edges and clean the acrylic with window cleaner to maximise its finish.

Woods Plastics

MetalsWoods

Plastics Metals

When connecting woods to plastics, the main type of permanent joining would be bolts and screws with the availability of adhesives and other types of joints(dove tail). On these two materials slight flaws such as scratches or marks are a big problem as they would show heavily. So because of this i will use carefully the use of adhesives such as epoxy resin, and if done correctly will look clean and be strong.

As my design will be using so many materials and process i decided to look at joining all of these different materials together.....

For woods and metals, a very efficient and strong method is the use of screws and bolts to hold these two together. After practicing with the use of bolts it seems the only valid and strong option as much of the strong parts of my design will be made of these two. It will also give me a chance to use the new finishes and using them together from the development above

And finally for the last two different materials, now plastics and metals are rarely used together due to their contrasting styles of construction, however such joining as sheet-metal nuts or rivets are a valid option rather than adhesives again, such joining as wielding would not work, so from here i will be using these two methods




Construction- Sized Model

Construction- speaker placement/ Arrangement

For practicing, viewing and changing the actual size of my design this will help me understand more about my design and will allow me to make mistakes in this product rather than my actual product. From Doing this sized model i have

realised that the angles of the design and the corners are very important so later in my

development i will have to look at this in more detail. Another point i will have to change will be the idea that it would be in three parts (page 36), but from now it will only be in two main sections with the top and bottom sections. This will help

reduce the error i could make in measurements and make it easier to join one the parts are

made.

At this stage i will need to look at where speakers will be

placed on my design to allow maximum effectiveness. Since

my original idea was to include 3 sets of two speakers placed on the area to the left, this my have to be

reduced as the size of my design will be be

big enough to old all of them, from this point i have

placed new rings of colour orange to tell where they will be placed. This allows all speakers to be seen and

also allow the sound to travel in all sorts of different directions to be heard all over the room




Construction- Wire Placement

Construction- Inside View Construction

As my designs main focus is to be as aesthetically pleasing as possible the idea of wires must strongly

be considered. Even if my design turns out to be battery powered there is still connector wires

that will be a possible problem. From this i have identified on the far right where

the initial wire will come from the speaker, then on the immediate right

shows where the wire will trace on a smaller scale and clearly shown on the left is the direct route

it will take. From practicing this route it will able me to hide the possible viewing point and so keep it looking

well finished and clean.

Due to the fact my product will have some open sections where

someone will be able to look inside it, i must consider the way it is laid and and how well it must

be finished. After looking a various sculptures inside and out, i noticed that from all views it does

have an artist point to it, and i must incorporate this too, as this is the case i will have to finnish both sides of my design and to put materials must as metals and woods to complete and fill out the design. This has changed

from my original idea and so a lot more time would have to be spent

on this aspect.




Construction- The joint of the sections

Manufacture- Joining design (Basics)

From the multiple images of my design, there are clearly two main sections to the design, however there is also the joint to

the wall mount which must also be considered. The idea of the sections would make it easier for me to create the design and

join it together in sections. Looking at the two largest sections, as they will be made of steel rods of some kind a clear strong wield would be done to solidify this joint and

make it permanent rather than the use of bolts and screws. The use of tungsten gas wielding would allow there to be a solid joint all along the two sections where they meet, this would able me to make both sections separately and join them at

the last stage, saving time on working around them.

From the beginning from a purely one sided view of one panel of my

design that there is a lot or room to attach and join parts of my design together, and over the manufacture i will be going into

more detail. So from the basics of joining my design this is the lower section split up, and here i

looked at the gaps where the struts of material would leave space and from a sculpture point of view this gives me a lot of choices with what i want

to do with this space, but as i have already looked at architecture in the shard i must keep this open to

follow my other research. But for this part of my research i plan to keep my design simple with minimal

amounts of struts to keep joining to a minimum and also to follow my modernism design movement.




Manufacture- Different order of Constructions

Manufacture- Template/ outline of design

etc....

Obviously the order i create my design will be very important as the whole design will be fairly heavy

with all the steel and will need to be constructed slowly and carefully so that everything will

be balanced rather than before where i thought i could create it all at once. To begin with i will create my sturdy wall joint, followed by the lower section,

this will allow me to judge what the weight will be like, then the

top section followed all all the smaller components of the design like the speaker switch

etc...

For my design i needed a template for my design where i can follow various parts of my design without making a mistake (such sections as general shapes, amounts of edges, width, general sizes, speaker placement, wire placement and also how the design will be pieced together. Also on this cardboard and MDF model i have circled in red where the major stress point will be and this is where extra care will be taken in terms of the joining processes and the materials finishings if there are any. Although i have used a thermoset glue, it has helped me practice and understand the problems i will have with wielding the design such as the tighter angles and the areas where there is minimal surface area and i will have to be more though rough with the joining.




Manufacture- Ways of constructing wall mount

There are many ways in which i can construct my wall mount which will be attaching to my design making it a wall mounted product. I can use more modern and traditional methods of wall mounting with images bottom right, they use

finely tuned materials to be able to hold as much weight in as little space as possible, however i have already

created one prototype in my development which has already worked well so i plan to

use this design, although i have changed one small thing to give my design just a little more stability, it is a small V shaped piece of material screwed into the wall piece and then a diamond shape on the

speaker side, rather than just laying all of its weight on the

bottom of the wall joint, i have also looked at the idea of a twisting

wall mount however this would cause problems from how rectangular the back of the

design is, so i will not be using that idea.




Manufacture- Ways i could make the frame/ structure

On this page, as my design will basically be a frame sculpture i have looked at different types of framed structures, buildings etc... and from all off the types of frames they are incredibly well balanced and strong at every point, i have looked at weaker parts of my design

already but now it is just the balance that i need to focus on, to achieve this the top section of my design my

have a less mass to reduce pressure on the bottom section, this would keep the

centre of mass lower and the overall weight of the design would be

severely decreased. I have also been looking at the image and framework above of a wooden home and from research i have found that there are 10 main strong beams/ columns of wood holding the structure up with the smaller beams giving stability and shape, i would like to use this idea but i would use

more like two or 3 main struts to hold the design up and the rest to give it its shape.




Manufacture- Ways i could make Base (wall to main body) Joint

For my design i did want a midpoint between the wall mounter and the actual design itself, and even since my design will not be going on the floor i have created a base. For this section coloured orange on the sketch to the right it would act simply to hold the main design all together. The elastomer that i plan to place in this position wouldn't

need much thought in terms of joining as firstly it wouldn't be seem plus rummer is an extremely good material to be bolted which

could work with all different types of materials. It would also give a certain amount of texture and class to the

design when being touched or being looked at. Another thing i have thought about is the

idea when it is not attached to the wall it must be laid down on the floor, however to make sure that the design can be picked up and can rest on the floor i will plan for the last bottom part highlighted green will be slightly longer and heavier so that the situation named above can be sorted, this would also help the usability of the

design.




Manufacture- Creating sharp clean edges

Key Inspiration:Keppel Bay, Singapore ‘World Architecture Festival 2012 Award Nominee’

A final Manufacture that i would like to look at with my design would be the idea of sharpening the metal on my design with the use of files, sanding and buffing to make it, not just to make it look better but also when I'm

joining this material it becomes a lot easier to join and makes the joint even stronger. Practicing this on aluminium it also works, this also makes the design have more emotion and feeling to it. This could be linked back to different materials i have used and how i have also finished them to be much sharper, and the way the design is going this will also contribute

to it.



Specification Check


My design has looked at making my design sharper going against my further spec. however i have used a variety of

materials and plan to use them also.

With the processes and materials i plan to use the cost will be high

From images and development my design looks like a modern speaker which sound be liked by my costumer

i have looked a lot about where it will be placed and it satisfies this section

i have done this by doing a sized model and and looking briefly at sizes

my design i out of the way however it is very sharp and could hurt someone if it it too low down the wall

the function will be its wall feature and being able to see inside the design, it fulfils the criteria here

i have used steel, aluminium, woods, plastic etc although not carbon fibre on a working model




Components- Parts in Wall Joint

Components- Wire conclusion

When looking at the wall design in terms of the components that i will use to create this section, i wanted to break up this part and see how the design well be pieced together. For this part it is very simple with splitting the design up into 4 simple sections and joined into two when the small parts on the top of the images are placed into the design. This gives my design simplicity which in term will make it easier to create and so able to be made in a higher quality. For the section to the bottom right it is one component however it will formed or moulded making it stronger in the longer term and also a better finish with no seams etc...

As before i have looked and developed the direction of all the wires, i now have though of a final point on the design to place this holder for an iPod/ mp3 player, this

would be placed on the underside of the bottom part of the design so that it does not effect the style of the speaker but also not the clutter the rest of the design with unnecessary parts and

components. The components of this holder will be made from sheet aluminium to fit in with

my design, this will keep that aesthetics consistent and clean.




Components- Panels

Components- Measurements*(mm)

For this component i am looking at i want to look at the panel and how it may be seen and joined. To begin with from the sketch to left my

plan is to place a panel of some sort of sheet material to cover some of my design, this my be acrylic or sheet

metal. However were i want to focus on joining this section together- i can join this together with

the use of adhesives but that will be messy- so instead i plan to pop rivet or drill which

would work on steel rods well.

For this development rather than looking at one individual component of my design i wanted to look as them as a whole unit in a working format. From here i looked at the specific measurements to make my design work properly in a real life situation. Clearly From the diagram to the left i have left out measurements for the inside construction, partly due to the fact it is hard to measure this distance but also as the inside is not as important as for the measurements as it only must have a strong core and not necessarily a particular pattern to follow.




Components- Angles to product

Components- The switches i will use and how they will be used

For my design to work and to be joined perfectly i have looked at the angles of my design so that it can look sleek and modern but also to be stable to hold its own weight once it has been built full and to its maximum mass with all the components and this will only happen with this development. For my angles i have given most strength through the use of angles with the green circled area, as this would be the section where most of the weight would be forced on and the lowest angle difference is the best. When looking at joining my product in more detail i have looked at compound joints where i will have to look at what angles i will have to make the two pieces of metal so that they join together to make the total angle (images right). I have measured and calculated *C, however to create this angle i have to cut the angles into the two materials first, i can use the equation to the right to do this accurately for all my angles

4

For these components i have tried switches 1 and 4, and looked at the others 2 and 3- and from looking at what would look best on my design and would complement my style the most, numbers 1 and 2 would fit with the materials of steel rods and sheets- and as before i have said how the switches will be lined up vertically along the side of my design i plan to change this so that they group the design in 2’s allowing easier accessibility and putting these components into the design. One this i have noticed is the use of joining switches to my design which would be done now with all the switches on one panel which would be then laid into the side of the design blending it into the design and making it easier to work with.

Components- Mid joint to the main design

Components- speakerThis is the design of speaker i will be using for my design as it uses the right colour scheme and it is the correct size to fit into my design also- For this component it has a diameter in length of around 90 and a diameter of depth of around 40mm, this size now gives my an idea of the sizes to cut out for the panels they will fit into, however i must watch out at the design is curved and the hole will have to be inch perfect. I will have to use a precise type of equipment to measure the diameter so that i can cut the correct size of hole.

At this point i am looking in more detail in the mid section of my design where the wall joint will be joined onto the main design structure- and so this part has to be as strong as possible! to do this i plan to create a dove-tail joint which is incredibly strong and then covering it on an elastomer to fulfil one of my previous criteria. Using this sort of method just makes the whole process a lot simpler once the components are created. It is also a more professional method of joining.




Components- Frame

Components- Frame continued

At my final stage i have used 3 different types of joining methods to see what is best for this component- The first using MIG wielding(top of triangle), this was a relatively quick process but left large bulks of material and often was difficult to clean up. The second technique(left of triangle and right) we have

used a braising to joining the components and this was the quickest to join but also the quickest to

sand down after. And finally to the right of the triangle using an acetylene torch to melt the material together, however this blew a hole into the steel which is a risk i’m not going to take. In conclusion i will be using the brazing rod as it is the easier and quickest for of joining.

My final two pieces of Development come from the main feature of my design which is the frame and i wanted to use this last as the rest of my development can work around this main already rather than working the other way round. For the frame i could use squared rectangular or circular types of steel rod however the decision will always be made on how easy it will be to make the shape of my design and the ability to join the product up in a physically strong way. And from the clear example on the right the use of square hollow tubing is the best and the edges can be lined up but also can cut to fit into shapes and the shape of my design

Specification Check


I have kept aesthetics constant throughout by looking at the components and the processes and materials that i

will you for them.

Using a range of materials has kept my design at a reasonably high price, i have achieved this criteria.

My costumer will be into sculptures, and from the components i have added, it still looks like a sculpture.

My design has not changed where it will be placed nor have i changed how it will be placed, i have completed

this criteria previously.

On measurements i have carefully decided on how large the design will be, and the structs as well.

Wires have been carefully mapped on the design and that will be the only issue with safety here.

My design has no specific function, i have not looked at this section, i have not completed this criteria.

In components i have completed this criteria



Final Design

Use of plain colours and sharp edges

The use of various

materials

Clean cut sculpture design

Wall connector on the back

Used in orthographic, about to hold

On the wall so away from most interaction

The use of buttons on the side.
