CASE STUDY

We have considered a medical instrument

manufacturing company, Aadarsh Instruments,

located in Ambala, for analysis which runs export

business of medical microscope. It is an ISO certified

company.

One of their model SL250 have a component

Named Focus Adjustment Knob for Slit Lamp in

microscope. This microscope has found applicationin the field of eye inspection.Value Engineering is

applied to the Focus Adjustment Knob.


3/14

ORIENTATIONIn the orientation phase, the project is

selected and those who are going to work theproblem are familiarized

Product selected is Focus Adjustment Knob for Slit

Lamp in microscope which is used to adjust the focus

of lens for magnification purpose.

The present specifications of this part and its

material used are costlier than the average industry

cost. Value of this product can be increased by

maintaining Its functions and reducing its cost or

keeping the cost constant and increasing the

functionality of the product.

INFORMATIONThe team is made familiar with the present state of

the project. Collection of information on quantities,

vendors, drawings, materials, manufacturingmethods, and costs.

Obtain Product Information

Product specifications are:

i.Material

Aluminum Bronze Alloy ii. Diameter of base plate 30 mm

iii. Thickness of plate--3 mm

iv. Cost of the scrap isRs. 293/Kg

v. Pieces Produced annually

8000 vi. Process usedC.N.C. indexing milling

vii. Cycle time2.5 min

viii. Anodizing2/min

ix.Material cost65 gm

x. Total Present costRs29.99/piece


5/14

SPECULATION

A technique that is useful for this type of analysisis brainstorming

During brainstorming these ideas were listed:-

i. Change design

ii. Change material

iii. Use plastic

iv. Make it lighter v. Change the production process

vi. Use nylon indexing unit


6/14

ANALYSISTechnical and cost analysis of the alternative

proposed. During this phase the value study orders,

collects, solidifies, and ranks the ideas generated in

the creativity phase.

For judging the ideas, the following designs werconsidered:

A. Function

B. Cost

C. Maintainability

D. Quality

E. Space

Each of these design criteria was given a weight age factor. This was carried out as

follows: each of the above criteria was compared with others, and depending on their

relative importance, three categories were formed, viz. major, medium, and minor. A score

of 3, 2 and 1 respectively was assigned to each of the levels.

The details are as given in the Table

are developed from the alternatives selected during

the analysis phase.PAIRED COMPARISON:

C Maintainability 2

D Quality 5

E Space 0=1(Assume

The above ideas were discussed and the best

feasible ideas were separated which were:-

a= Change the material to steel

b=Use Nylon unit

c= Use existing material

PRESENTATION

The presentation phase is actually presenting the

best alternative (or alternatives) to those who have

the authority to implement the proposed solutions

that are acceptable.

IMPLEMENTATION AND

FOLLOW UPDuring the implementation and follow-up phase,management must assure that approved

recommendations are converted into actions.

ResultThe total savings after the implementation

of value engineering are given below:

Cost before analysis Rs.29.99/-

Total Cost of nylon knob Rs.18.40/-

CONCLUSION

In the Case Study discussed abovewe have used the concept of Value

Engineering to analysis the focus

adjustment knob of microscope andwith the critical evaluation of it we

were able to increase the value of the

product by substituting anothermaterial in place of the one that is

currently in use.
