In order to create our product, we followed the Engineering Design
Process. Here's what we did:
Defining the Problem: We looked at the conditions in Soroti and recognized a lack of affordable prostheses for local amputees.
Background Research: We found out more about conditions in the region and began working our design around their aesthetic preferences and physical requirements
Brainstorming: We came up with several designs for the foot, ranging from carbon fiber plates to aluminum spring configurations. We also came up with several socket designs, including 3D printed plastics, steel hoops, and fabric straps.
Choosing the Best Solution: We found the best comprise of price and weight in a casting tape socket and acetyl resin foot, and began our design.
Building a Prototype Test and Redesign: Using simple and easily replaceable machining practices, we began building the leg. Several modifications to the connection between the foot and pylon were required, allowing us to iterate on our design.
