Variable Rigidity Ankle


Need statement:

Current lower leg prostheses have rigid components where a natural ankle
would allow for flexion. Consequently, these prostheses greatly limit the type
and amount of activity their users are able to participate in. In the case of our
challenger, Phil, the rigidity of his prosthesis has made every day activities uncomfortable, difficult, and in some cases impossible. Accordingly, Phil has expressed a need for a device capable of the appropriate flexion in the ankle that is necessary for walking on uneven terrain, inclines, and other daily activities. The QL+ Club intends to design and build a device that will allow Phil’s prosthesis to have more natural flexion and range of motion where his ankle would be.
End Goal:

By June 2016, our team will completed and manufactured the final design of the QL+ Variable Rigidity Ankle.
