Mechanical Engineering
Originating from QL+'s customer requirements, the main technical specifications were to have 80% physiological range of motion, elastic energy return, impact absorption, and no external power sources. Based on the background research conducted and the discussions with experts in the field, the project team decided to focus on designing a prosthetic that focused on plantarflexion and dorsiflexion for a more comfortable gait. The main components of the final design are a hydraulic shock absorber, cam, torsion springs, heel, stopper, and separated keel. The heel, front and back keels, and stopper were manufactured out of carbon fiber. The link, lever, attachment …

Design And Development Of A Stair Ascension Assistive Device For Transfemoral Amputees, Casey Michael Barbarino
Master's Theses
Transfemoral amputees around the world experience increased difficulty in climbing stairs due to lack of muscle, balance, and other factors. The loss of a lower limb greatly diminishes the amount of natural force generation provided that is necessary to propel oneself up stairs. This study investigated possible solutions to the problem of stair ascension for transfemoral amputees by the means of designing and developing an externally attachable device to a prosthesis. The number of amputations from military service has greatly increased since 2008, which shows there is a clear need for assistive devices (Wenke, Krueger, & Ficke, 2012). With the …
