    Design Strategies 1

    Many developed countries have technological advancements and forms of social support

    which help satisfy the needs of its inhabitants. However , the majority of the worlds population s

    do not have these technologies or support systems. How can this gap be closed? Numerous

    organizations such as Engineers without Borders, Project H, Design Accord, and Architecture

    for Humanity have started to design products for these underprivileged communities in hopes

    of eradicating a social issue or improving their standard of living. My thesis will focus on some

    organizations and their products that have been designed with this in mind. Many of the products

    aim to help reach the goals established by The United Nations (Smith, 2007) in hopes of

    convincing wealthy countries to help improve the lives of poorer nations. There are eight goalstotal, and they are known as the Millennium Development Goals.

    Goal 1: Eradicate extreme poverty and hungerGoal 2: Achieve universal primary educationGoal 3: Promote gender equality and empower womenGoal 4: Reduce child mortalityGoal 5: Improve maternal healthGoal 6: Combat HIV/AIDS, malaria and other diseases

    Goal 7: Ensure environmental sustainabilityGoal 8: Develop a global partnership for development

    In order to help combat these world problems and reach these eight goals many companies have

    developed assistive products in order to help these underprivileged communities in their needs.

    Skeptical about the sudden altruistic actions of some of these capitalistic companies, I

    chose to do an investigation on some of these assistive products and determine whether they

    really helped fix the problem. Anthony Crabbe (Crabbe, 2012) explains that there three different

    strategies taken when developing solutions for developing countries and they are charitable,

    networked, and social business. The charitable strategy is one in which a developed country

    designs a product to be easily distributed to the communities of developing countries. An

    example of a product fi tting under this strategy is the French product Plumpynut (Pilloton,

    2009). Plumpynut is a food supplement high in nutritional value that helps children in

    underprivileged countries fight malnutrition. Plumpynut is easily produced and distributed to the

    children of developing countries. The network strategy allows underprivileged communities to

    work with a network of international companies in developing their own product(s) for either

    personal or communal income (Crabbe, 2012). One such situation falling under this strategy was

    the manufacture of fuel briquettes in developing countries. The Legacy Foundation wanted to

    lessen the physical burden of collecting firework on women of underprivileged communities, so

    they started promoting the use of resources found in local urban and agricultural wastes. Womenwere then able to use their local resources and build a surplus of fuel briquettes which they could

    then sell locally. Finally, the social business strategy launches a local business in a developing

    country that uses the sale of local commodities on the global market as a form of self-

    sustainment. Many products under the Fair Trade system fall under this strategy, but one

    specific example is Recycled Tire Furniture. Made from recycled tire rubber, The Recycled Tire

    is a product handmade from a cheap resource by the people of underprivileged communities to

    then be sold on the global market. My thesis analyzes products from each strategy, in order to

    assess the advantages and disadvantages of each strategy.

    Section 1

    The products included in section one fall under the charitable strategy. These are products

    which were designed and manufactured by developed countries for developing countries. All the

    products are intended to fix a personal or social issue.

    Adaptive Eye Care

    Design Strategies 3

    The World Health Organization estimates that currently there are over one billion people

    suffering from uncorrected vision yet remain untreated (Pilloton, 2009). Although people survive

    without proper vision there is a large difference in the accommodations for the visually impaired

    in developed countries versus that in developing countries. To begin with, all citizens of

    developed nations have resources that aid them in their daily lives. These resources range from

    education to assistive technologies for disabilities, but the same cannot be said about developing

    countries. For example, the majority of Nepals population suffers from uncorrected vision, but

    most remain untreated. This has a significant effect on children, where uncorrected vision affects

    them in more ways than one; one such effect is on their education. Over ninety percent ofchildren that drop out of the education system blame vision as the main contributing factor, and

    this leads to live a life as a field laborer, and lose the opportunity to advance academically and

    professionally (He et al., 2011). Is there a cheap and efficient solution to correcting vision for the

    people of underprivileged communities?

    Engineer Joshua Silver saw a need for help and developed a cheap alternative to glass

    lenses which he called Adaptive Eye Care (Shulman, 2003). Silver found that when silicone oil

    is dispersed between a pair of flexible membranes, the result is something that works similar to

    glass lenses, but at a fraction of the cost. He also realized that the magnification could be

    adjusted by varying how much silicone was pumped between the flexible membranes. In order to

    use this technology Silver proceeded to develop an inexpensive frame for the membranes with a

    wheel that adjusted the amount of silicone dispersed between the membranes. This design

    allowed the users to self-adapt the refraction of the glasses to meet their needs. Since the

    refraction could be self-adjusted this eliminated the need for an optometrist and made the product

  • 8/13/2019 Daniella Smith - Senior Thesis

    5/23

    Design Strategies 4

    even easier to manufacture and introduce. Silvers design not only provided an immediate health

    solution, but also made correcting eye vision a quick, uncomplicated, and easy process.

    But is Adaptive Eye Care really as effective as it appears to be? A study conducted by

    Douali and Silver (2004) tested the effectiveness of this adaptive eye care among communities in

    Ghana, South Africa, Nepal, and Malawi. Douali and Silver tested the Adaptive Eye Care on 213

    adult subjects suffering from uncorrected vision. First, Douali and Silver administered an eye

    reading chart to the subjects and recorded the refraction that each subjects chose for themselves.

    They then compared that refraction to the refraction recommended by a professional optometrist.

    Douali and Silver did this because they wanted to assure themselves that the design of the

    eyewear was intuitively adjustable and that users could administer the proper amount of silicone

    and reach a similar refraction to that which was recommended to them by the optometrist. If the

    results showed no detectable difference between the two refractions, Douali and Silver believed

    this would prove that the users could in fact adjust the glasses themselves without the help of

    professionals. Douali and Silver asked subjects to turn the wheel and adjust the silicone levels to

    the point at which their vision became clear and again for when their vision started to become

    blurred. They then asked the subjects to choose the most appropriate refraction settings for

    themselves. Following this, Douali and Silver then compared the refraction recommended by the

    professional to that which was self-determined by the users. What Douali and Silver found was

    that the participants were able to successfully obtain better vision through the Adaptive eye care

    process and that the differences between both personal and professional refractions were

    insignificant among all participants.

    Although these studies showed that self-adjusted refractions for adults were easily as

    effective as optometrist administered refractions, would this be the same for children? It is

  • 8/13/2019 Daniella Smith - Senior Thesis

    6/23

    Design Strategies 5

    important that children can properly use the device since uncorrected vision can pose many

    problems for them. A study by He et al. (2011) addressed this very question by testing 554

    school children in China, and using the methods used by Douali and Silver. The only difference

    between the two studies was that afterwards, He et al. administered a visual acuity test in order to

    measure the success of the childrens self -adjusted refraction. The results showed some of the

    children had inaccuracies between their recommended refraction and their self-prescribed

    refraction. However, He et al. considered that any improved eye vision was better than none and

    therefore the differences were deemed insignificant. He et al. also believed the Adaptive Eye

    Care could not be held entirely responsible for the inaccuracies. He et al. hypothesized that thechildren had a higher tolerance for unsatisfactory visual perception, due to their age and their

    tendency to adjust the silicone levels with less patience and precision.

    LifeStraw

    Water is a basic survival need, yet millions of people are without a reliable sanitary water

    source. If there is not a sanitary water source available what should the people of these

    communities do? Should these people wait until they find clean water and run the risk of

    dehydration? Or should they drink the bacteria-filled water they have available to them? Either

    option carries a detrimental health consequence, but what if there existed a portable filter which

    provided a healthy alternative to these options? Recently Danish company Vestergaard Frandsen

    designed a product, called the LifeStraw, which could do just that (Pilloton, 2009).

    Nearly two decades ago Vestergaard Frandsen (Pilloton, 2009) designed a home water

    filtration system for families in developing countries that where lacking a clean water source.

    The filtration system was made to reduce worm disease and decrease other waterborne diseases

    caused by the intake of unsanitary water. The home filtration system, which they dubbed the

  • 8/13/2019 Daniella Smith - Senior Thesis

    7/23

    Design Strategies 6

    LifeStraw Family, provides a simple and efficient way to obtain clean drinking water. The

    LifeStraw Family uses the same technology found in the municipal water treatment facilities of

    several develop countries; it also requires no electricity or batteries using gravity as the

    filtrations main driving force. In addition the design also has a guaranteed lifespan of 3 years.

    The design of the LifeStraw Family consists first of a bucket used to hold unsanitary water; it is

    then suspended high enough in order for the gravitational pull to force the unsanitary water

    down through a rubber tube running from the bottom of the bucket. From here the water enters a

    filtration pipe which releases potable water when pumped. So far the Danish company has

    donated over 900,000 LifeStraw Family filters which continue providing safe drinking water toover 4 million people in Africa (Frauchiger, 2011).

    However, the Lifestraw Family did not immediately provide clean drinking water. It

    required the transportation of water from a central source to a residence with a LifeStraw Family

    filtration system, and even then time was required for the water to filter through the system to

    become potable. Vestergaard Frandsen realized that it is necessary for these people to have

    access to safe drinking water 24/7; so they designed a sister product to the LifeStraw Family. In

    2005 the LifeStraw Personal was released (Frauchiger, 2011). The LifeStraw Personal uses the

    same technology as the LifeStraw Family, but the design was compacted and made to be portable

    and provide clean drinking water within seconds. The LifeStraw Personal is not only affordable,

    but also looks similar to a large straw, and has a mouthpiece that allows users to submerge the

    end of the LifeStraw into unsanitary water, and use suction to filter the water up through the

    filtration system (Pilloton, 2009). This product gives people the opportunity to carry an efficient

    filter with them wherever they go and drink freely from any water source without having to

    worry about the harmful health consequences.

    Design Strategies 7

    While the product is a suitable and innovative solution, is the filtration system really as

    effective as it claims to be? Almost two million people die each year from waterborne diseases,

    so it is important that the LifeStraw provides water free from all disease-causing bacteria (Smith,

    2007). Vestergaard Frandsen claims the LifeStraw filtration technology filters out 99.9999% of

    all bacteria found in water (Pilloton, 2009). In order to test this claim Boisson, Schmidt,

    Berhanu, Gezahegn, and Clasen (2009) did a randomized trial in Ethiopia in order to determine

    the effectiveness of the LifeStraw Personal. Boisson et al. included 313 families in their study,

    which they randomly assigned the families to either the control group or the intervention group.

    The participants in the control group did not use a Lifestraw device, while the participants of theintervention group used the LifeStraw Personal for the duration of five months. Then Boisson et

    al. documented and compared the health issues experienced by participants in each group.

    Elsanousi et al. (2009) also conducted a similar study on the health impact the LifeStraw

    Personal. In their case study Elsanousi et al. recruited 647 participants from a town in Sudan to

    use the LifeStraw over the course of two weeks. At the end trial, Elsanousi et al. questioned the

    participants about any health changes or issues they experienced with the LifeStraw Personal.

    Both case studies showed a significant decrease in the number of participants that

    suffered from diarrhea, but there were participants from each case study that still reported

    diarrhea while using the LifeStraw Personal. However, many of these participants admitted to

    not using the LifeStraw all the time, either because they forgot to or found it to be a nuisance. A

    significant amount of participants from both studies said the reasons why they did not always use

    the LifeStraw Personal was because it required a significant amount of suction force and did not

    deliver sufficient water fast enough. Nonetheless, the majority of the participants agreed that the

    LifeStraw was easy to carry, made water safe to drink, and improved the taste (Boisson et al.,

    water and energy sources available, the distressed land, the arid harvest, and the local farmers

    struggling to sustain the land even with such strenuous labor, Barnes decided to use his

    engineering experience and come up with a low-cost solution. Barnes quickly and innovatively

    invented the Treadle Pump. The Treadle Pump is a water pump, better known as an irrigation

    pump, which draws groundwater to the surface of the land using a suction method (Fandika et

    al., 2012). Originally the Treadle Pump consisted of only bamboo stalks and a metal cylinder.

    The bamboo stalks were used to build a pumping mechanism similar to a stair-stepping machine.

    A cylinder was attached to the end of the bamboo stalk, and openings to water were dug up to

    place the Treadle Pump over. So when the pedal or step of the Treadle pump was stepped on itforced the cylinder up and down a narrow opening, which created suction underground. The

    suction then forced the water out from underground and onto the surface, where it could be

    collected (Smith, 2007). Then during the 1980s the Treadle Pump was bought by the American

    corporation International Development Enterprises, also known as iDE (Smith, 2007). iDE then

    started marketing the pump to other communities in Bangladesh, and as word spread about an

    affordable product that could provide a reliable water source, and improve cultivation, the

    product became widely known.

    A study by Fandika, Kadyampakeni, and Zingore (2012) evaluated the performance of

    the Treadle Pump for crop production in Malawi. Between 2005 and 2007 Fandika et al. assessed

    a tomato crop along with an intercropped maize/bean crop. They also had three replicates of each

    crop in order to compare and contrast accurately any differences and/or similarities observed

    between the crops. There was a significant difference in harvest growth among the tomato

    varieties; the one under the Treadle Pump condition benefitted considerably. However, the

    Treadle Pump did not seem to have a growth effect on the maize/bean crop, as there was no

    Products in this section are part of the network strategy. With the help of a network of

    international companies, this strategy helps underprivileged communities develop their own

    products. Products are developed and sold in order to generate either personal or communal

    income.

    Hippo Water Roller

    Millions of people in developing countries struggle with obtaining reasonable access to

    potable water. So is there an innovative, practical, and reliable resolution that could possibly

    provide these people with potable water? Thankfully engineers Pettie Petzer and Johan Jonker

    (Pilloton, 2009) created a product that has become very popular because it not only offers

    immediate relief, but decreases the physical demand of the task while increasing the return.

    In 1991, South African engineers Petzer and Jonker (Pilloton, 2009) saw firsthand how

    the African communities lacked access to potable water. Initially these underprivileged

    communities were using a very traditional mode of transporting water from the source to their

    homes by carrying five-gallon metal buckets, on their heads. Even though this method allows

    them to carry the buckets for long periods of time, ultimately it starts to cause spinal damage.

    The spinal damage limits their ability to successfully transport potable water to their homes, and

    also keeps them from doing daily tasks.

    Therefore, Petzer and Jonker (Pilloton, 2009) developed the Hippo Water Roller, which is

    essentially a barrel that holds up to 24 gallons of water; nearly quintupling the volume of water

    one person can transport when compared to the bucket method. One full barrel supplies an

    family of five with enough water to last them a week. Additionally, the Hippo Water Roller has a

    metal handle bar which allows the user to roll or push the barrel instead of carrying it requiring

  • 8/13/2019 Daniella Smith - Senior Thesis

    13/23

    Design Strategies 12

    less effort per water volume than the bucket. This makes transportation easier and more efficient,

    allowing users to transport 40 pounds of water at half the physical demand of transporting five

    gallon buckets. The Hippo Water Roller is easily introduced into the African communities and is

    guaranteed to withstand the African terrain for seven years; after which point a new product is

    required because there are no replacement parts. Petzer and Jonker have made life easier for

    nearly 30,000 families in the past 20 years by creating a simple and efficient product.

    However, while the Hippo Water Roller has provided aid to many families, are the people

    of these African communities able to afford it? Most of the Hippo Water Rollers have been

    provided to families through charitable donations, so in order to answer this question Anthony

    Crabbe (2012) conducted a case study that evaluated the Hippo Water Roller as a solution to

    water accessibility. What he found was that, while the product lives up to its description and

    functionality, people of underprivileged communities cannot afford the product. Therefore, users

    must rely solely on charitable support from organizations like the Africa Foundation and

    UNICEF; thus rendering the funding for this gift aid product completely dependent on donations

    and charity. This makes the Hippo Water Roller an unsustainable solution, an unacceptable

    dilemma considering the significance of the present problem and the health impact it could

    potentially have on these communities in need.

    In order to make the distribution of the Hippo Water Roller less dependent on charitable

    donation an alternative solution was purposed. Imvubu Projects the manufacturing and

    distribution company of the Hippo Water Roller came up with an idea to make the Hippo Water

    Roller cheaper and affordable for people of developing countries (Press Briefs, 2010). Imvubu

    Projects designed a compact production plant for the Hippo water rollers one small enough to

    fit in a used shipping container and efficient enough to produce 650 units a month, that could be

  • 8/13/2019 Daniella Smith - Senior Thesis

    14/23

    Design Strategies 13

    set up within the African communities in need of Hippo Water Rollers. The problem with this

    solution is that the workshops cost about $150,000 to build and implement. It also takes weeks to

    properly train and teach employees how to manufacture the product. Thus leaving charitable

    organizations with a difficult decision to make; do they delay assistance in the transportation of

    potable water and invest $150,000 in a portable plant, or invest the same amount in distributing

    already made Hippo Water rollers and provide immediate relief to over 1,500 families in need?

    While the decision could be difficult, charitable agencies need to think about the long-term

    effects; wouldnt this solu tion ultimately maximize the aid given to these communities by

    lowering the cost of future, locally-manufactured Hippo Water Rollers? And let us not forget thatthis solution also provides employment to locals, thus offering long-term assistance to these

    communities. For this reason, the Hippo Water Roller is considered a networked strategy. It

    works with international companies to help them locally develop their own Hippo Water Rollers.

    In order to continue coming up with innovative solutions and improvements to the Hippo

    Water Roller project, Imvubu Projects has started a partnership program with Engineers without

    Borders, which is an organization based in San Francisco that is committed to providing

    solutions and assistance to people in developing countries and other troubled communities

    around the world (Pilloton & Press Briefs, 2009, 2010). With their program the Project H

    Design they are working toward enhancing the development of t he Hippo Water Rollers and

    lowering its cost. They also hope to advance the functionality of the Hippo Water Roller by

    incorporating a water filter. This would relieve the users from the restriction of only being able

    to collect water from central and inconvenient clean-water sources, and instead allow them to

    transport water from any nearby source.

    Products in this section are part of the social business strategy, which establishes local

    businesses within developing countries. This strategy promotes exportation of commodities

    and/or the development of products made from local materials to be sold locally or globally.

    Basic Utility Vehicle

    While numerous developed countries are graced with various modes of transportation

    from public transportation to personally owned automobiles transportation in developing

    countries is far from being as convenient or luxurious. The reality is that many of these

    developing countries are without the means or infrastructure to implement a public transportation

    system, and the majority of the people cannot afford a vehicle of their own. Despite the fact that

    many communities have survived thus far without a formal method of transportation, they are

    still in need of a more effect form of transportation. Those in most need are farmers in rural areas

    who lack dependable and reasonable modes of transporting produce, equipment, and supplies to

    the fields. The basic design of a vehicle is made up of a motor, a couple pairs of wheels, and a

    few materials to build a basic frame. So is there a cheap and reliable vehicle available for the

    people of underprivileged communities?

    The Basic Utility Vehicle, abbreviated BUV, is a vehicle that has been designed to be

    utilized in developing countries. Designed and assembled by the Institute for Affordable

    Transportation (IAT), an Indianapolis-based charity, they wish to provide inexpensive and

    suitable forms of transportation to communities in developing countries in hopes of improving

    their standards of living (Reese, 2004). First started over a decade ago, the IAT holds a yearly

    contest known as the BUV Design Competition in which engineer college students and

    professors collaborate in creating a simple, low-cost utility vehicle that can help low-income

    people (Pilloton, 2009). The competition has many guidelines and requirements set, in order to

  • 8/13/2019 Daniella Smith - Senior Thesis

    16/23

    Design Strategies 15

    make the vehicle as practical for developing countries as possible ( Basic vehicles, 2010 ). A

    few of the main requirements that the BUVs must meet are as follows: a carrying capacity of at

    least 1000 pounds, a total cost of $900, a max weight of 500 pounds, and a top speed of 20 mph.

    The competition has two parts, the first part being design and assembly which composes the

    majority of the competition. The second half of the competition consists of many driving tests.

    Because many developing countries lack infrastructure the vehicles must withstand a variety of

    terrain. Therefore, during the second part of the competition the vehicles must pass a range of

    obstacle courses in order to be suitable for underprivileged communities. If vehicles survive and

    pass the competition they have the opportunity of being shipping overseas to help those in need.But, is this competition effective? Do students really know what farmers in developing countries

    want?

    In 2007 the first BUV was shipped overseas to Cameroon, Africa. It was purchased by

    the African Centre for Renewable Energy and Sustainable Technologies, also known as

    ACREST (African SUV, 2013). The vehicle was made from new materials and recycled auto

    parts found in the United States. However, from the beginning there were problems with the

    BUV. First of all IAT forgot to consider repair and using foreign automobile parts made repair

    expensive and unrealistic. Secondly, IAT did not stay within a reasonable price range during the

    development of their BUV. IAT first suggested a price of $5,000 which is obviously too

    expensive, especially when you consider the additional shipping, import, and repair fees that

    were not included. ACREST asked for adjustments that would make the BUV affordable and

    suitable for the farmers of Cameroon. IAT, feeling overwhelmed and under qualified, asked for

    help from Purdue University, which was a university known for its advanced engineering

    programs. The students at Purdue thought the best thing to do was ask the farmers in Cameroon

  • 8/13/2019 Daniella Smith - Senior Thesis

    17/23

    Design Strategies 16

    to develop their own truck; once they did the Purdue students were able to successfully produce a

    suitable vehicle. The students completely redesigned the BUV, and while they continue to

    redesign it during their annual competition, the most recent design is by far the most sustainable.

    The current BUV only costs $1,200 in local materials to build. Using local materials not only

    lowers the cost of development and repair, but also gives communities the option of locally

    making their own BUVs. In addition, it gets 50 miles per gallon, goes 25 miles per hour, and can

    transport 2,000 pounds. As a result, the BUV is frequently used as ambulances, construction

    vehicles, and even school buses (Pilloton, 2009). For the rural communities in developing

    countries, the BUV has become a versatile and suitable method of transportation.

    Jaipur Foot

    Prosthetic devices have been a solution for amputees for many years. However they can

    be very expensive, and as a result many amputees of developing countries are unable to afford

    them. Without a prosthetic, amputees of underprivileged communities struggle in carrying out

    daily tasks and meeting the physical requirements needed for survival. Living in such conditions

    have forced amputees to use makeshift prosthetics. However, the majority of the time makeshift

    prosthetics do not provide amputees with the proper flexibility needed to accurately and

    effectively perform their duties. So, is there another solution or product that can provide

    amputees with the mobility needed to complete fundamental everyday tasks, while still

    maintaining a reasonable price tag?

    Orthopedic surgeon Dr. P.K. Sethi and craftsman Ram Chandra Sharma developed a

    product they called the Jaipur Foot (Pilloton, 2009). Named after the Indian city for which it was

    developed, the Jaipur Foot was originally designed in 1968 for the local amputees, specifically

  • 8/13/2019 Daniella Smith - Senior Thesis

    18/23

    Design Strategies 17

    the landmine victims. Sethi and Sharma saw difficulties being experienced with the American

    prostheses that had been donated to some of the landmine victims. The American prostheses

    were not only expensive, but their sturdy metal designs offered little mobility (McGirk, 1997).

    The lack of mobility made everyday work more difficult for the amputees. In addition, the

    prostheses could not be worn without proper footwear and this posed an additional problem for

    daily worship. Shoes are prohibited during any religious ceremonies, and as such made worship

    even more difficult for amputees. So Sethi and Sharma started making different prototypes in

    hopes of creating a alternative which could provide mobility and be more suitable for the harsh

    terrain and labor-intensive lifestyle.

    First Sethi and Sharma developed a prosthetic foot made completely of rubber, and while

    it presented more than enough flexibility it was not durable. The rubber was not able to

    withstand the rough landscape and within days the prostheses shredded to pieces (McGirk,

    1997). They made some adjustments to the design by reconstructing the rubber foot using a

    lighter and more durable rubber, much like the rubber used for bicycle tires. They then attached

    the foot to a wooden ankle hinge, which provided just enough flexibility and sturdiness. The

    result was an inexpensive prosthetic that not only lasted five years, but also only took 45 minutes

    to construct out of local materials. Sethi and Sharma claimed that the Jaipur Foots weightless

    and flexible design made it possible for amputees to climb, run, ride bicycles, and do almost

    everything else they used to do pre-injury. In addition, the current Jaipur Foot can mimic almost

    every foot movement (Pilloton, 2009).

    A study by Kabra and Narayanan (1991) wanted to test this claim so they came up with a

    study to assess the functional limits of the Jaipur Foot. To test the flexibility, the dorsiflexion and

    heel compression flexes of the Jaipur Foot were measured, recorded and compared to the average

    flexion measurements of a natural human foot. What Kabra and Narayanan found was that the

    prosthesis matched the flexions of the natural foot almost every time. In order to test the

    durability, Kabra and Narayanan exposed 26 Jaipur Foot prostheses to an extensive cyclic

    exercise and recorded the deterioration of the prostheses after every 500,000 cycles until they

    reached three million cycles. They determined that after three million cycles, the deterioration

    level of the Jaipur Foot was minimal as only a small abrasion appeared. Overall, the Jaipur Foot

    is a reliable and effective prosthesis which is built simplistically and inexpensively. Handled by

    the charity Bhagwan Mahaveer Viklang Sahayata Samiti, the organization provides amputees in

    developing countries with artificial legs ($28). As of today, the Jaipur Foot has helped nearly onemillion amputees from Nigeria, Vietnam, Afghanistan, to Honorduras (Pilloton, 2009).

    Both the Basic Utility Vehicle and the Jaipur Foot fit in the Social Business strategy.

    Purdue students supplied the locals of Cameroon with the skills necessary to build their own

    BUVs, and the Jaipur Foot is also made by the locals of Jaipur, India. Since both products are

    also made of local materials, this has enabled these communities to develop them these products

    locally. As a result, they can then sell the products in both local and export markets; thus,

    creating a social business.

    Conclusion

    While all three design strategies offer three very different solutions, is there a superior

    strategy among the three? Lets try to assess the advantages and disadvantage of each strategy, beginning with the charitable strategy. As we saw from the Adaptive Eye Care, the LifeStraw,

    and the Treadle Pump, the charitable strategy is the simplest and quickest solution. This strategy

    does not have to worry about introducing a manufacturing infrastructure to these underprivileged

    communities, because the products are made by developed countries (Crabbe, 2012). However,

    this strategy is very dependent on developed countries and their endorsement of charitable

    causes. If a developed country suddenly does not support such a charitable cause, the people of

    underprivileged communities are left to find an alternative way to support themselves. If

    charities stop donating the Adaptive Eye Care, the LifeStraw, or the Treadle Pump people will

    have to find a different way to deal with uncorrected vision, unsanitary drinking water, and the

    lack of reliable water sources. Granted some of these products can inexpensive enough that

    people of underprivileged communities can potentially afford them, but this dependency and

    unreliability makes the second and third strategies seem like a better choice.

    The networked and social business strategies are seen more as actions to help people of

    developing countries to independently maintain their basic needs. These strategies also give

    underprivileged communities the opportunity to gain income or benefit profitably from such

    endeavors. The Hippo Water Roller, The BUV, and the Jaipur Foot each offer the community a

    way to use their skills and local materials to reproduce a product for local and global markets.

    However, both the networked and social business strategies also need to consider the

    implementation of infrastructure and initial investments required to set up such strategies. While

    the Hippo Water Roller and the BUV required months and even years to completely introduce

    and apply in developing countries, the products of the charitable strategy required no time at all.

    From the three strategies, each has their advantages and disadvantages. The charitable

    strategy offers developing countries an immediate solution to a global problem, while the second

    and third strategies offer a long-term solution that could potentially help stabilize the problem

    and even increase communal income. Perhaps, the best strategy depends on the problem at hand

    and whether an immediate solution is needed or a long-term strategy could be applied. We must

    realize that while none of the strategies seem to be able to meet all the needs of underprivileged

    communities, all the strategies provided support for the communities of developing countries.
