Background
Goobers
Our team consists of four members: Jeff Bernard, John Hackett, Jennifer Laurin, and David Sanders. We've named our team "Goobers." We are engineering students from Engineering 215: Introduction to Design. Multiplicity is our semester project for Fall 2008. The Goobers have been assigned the task of modifying the Full Belly Project’s current design of the Universal Nut Sheller so that it can be sold in the United States for household use. The proceeds from selling counter-top nut shellers in the United States will help to fund the spreading of technology abroad. Furthermore, the modified nut sheller will promote awareness of the Full Belly Project’s goals.
The Full Belly Project
Jock Brandis created the Universal Nut Sheller in 2001 to help women in Mali shell peanuts to feed their families. It is a modification of a Bulgarian peanut shelling design (Our History, 2008). His design is inexpensive and durable. The Universal Nut Sheller allows a person to shell nuts 40 times faster than they could by hand. The Full Belly Project has successfully taken their design to 17 countries, including Uganda, the Philippines, and Guatemala (Our History, 2008). To keep costs down, The Full Belly Project ships lightweight fiberglass molds instead of shipping the device itself. The molds are then used to create multiple Universal Nut Shellers in one location (Ward, 2006).
The Full Belly Project’s goal is to provide residents of rural communities in developing countries with improved nutrition and possibilities for economic growth. Their mission statement is: “The Full Belly Project designs and distributes income-generating agricultural devices to improve life in developing countries.” They hope to accomplish this by using education, appropriate technology, design and innovation (Our Mission and Values, 2008).

Description of Final Project
Multiplicity uses different rotors, shown in Figure 1(a,b,c), to accommodate multiple nut types and sizes.

Fig 1a: Original Rotor
-
Fig 1b: Parabolic Rotor
-
Fig 1c: Smaller Rotor
Multiplicity utilizes three different rotors designs. Each rotor is made of aluminum and specializes in different sizes of nuts. The first rotor design, shown in Figure 1(a), has the same shape and size of the Full Belly Project’s small nut sheller rotor. While testing the rotor, the Goobers found that this rotor works best with peanuts.
The second rotor design, shown in Figure 1(b), utilizes a rotor that is ½ inch smaller in diameter than the first rotor and has a rounded top. This design allows for a larger sized nut shell to fit between the casing and the rotor. The rounded top portion of the rotor keeps the nuts from getting stuck on top of the rotor. The third rotor, shown in Figure 1(c), is also a ½ inch smaller in diameter than the original rotor, but keeps the same shape as the first rotor.
Multiplicity’s base is shown in the Figure 2. The base allows for easier clean up and storage. The design utilizes a removable solid base to allow for easy storage. To minimize clean up, multiplicity implements a drawer inside the base to catch the processed nuts. By adding a peanut shaped handle and making the nut sheller out of aluminum, the Goobers were able to add to the nut sheller’s aesthetics.
