A trans-radial prosthetic arm for the sport of rock climbing. Currently, almost all prosthetics are designed for general use, with a ‘one does all’ outlook. This product aims to turn disability into ability by designing specifically for the task. SCALO is fully mechanical and modular, aiming to be as economical as possible. The aluminum fairing is designed to dent and deform under contact while in use, developing with the user and becoming a more personal item as time progresses.
My research for the project included visits around the UK to disability clinics, climbing trips, hospitals and the collection of 3D scan data. Throughout the project I tried to drive the design based around my hero users, the men and women who I met from the British Army who had lost their arms during conflict.
The tool can be rotated through 360 degrees, helping users to complete almost all handholds, however once under force the tool locks in place for safe climbing. The device is attached to the user by a silicon sleeve worn over the stump with a fabric elastic band worn above the elbow creating a suction lock. This sleeve houses a stainless steel prong that attaches through the socket of the device and is easily removed by release pin.
Throughout the process the use of prototyping was absolutely paramount to creating the best possible design. This ended with creating a fully working prototype using a combination of 3D printing, metal fabrication, vacuum forming and CNC machines.
