Low Cost Prosthetics for Kenyans

The Design Challenge

How can we best adapt the 3D printed Phoenix hand for a low income Kenyan demographic considering ergonomic physiological factors and material selection?

Summary of Research

In summary, Kenya’s environment, economy, and population have a significant impact on the usability of a prosthetic hand. These factors influence both ergonomic physiological factors and the material selection of the hand. Ultimately, all design specifications created in within this papaer were fulfilled with there being compromises between modifications and price. The product was estimated to cost around 7500 KSH which was calculated by utilizing researched information. So, the phoenix v2 hand design was best adapted through adding Ninjaflex fingertips, strategic placement of padding, ventilation, and spring joints. Through manipulating this design, the function, usability, and ergonomics of the hand are enhanced and targeted towards the demographic. With that being said, the final modified design could be implemented for a future Hand Out recipient. My hope is that the findings in this paper have real-world applicability and will be able to help the lives of Kenyans.
