Jambe outlines the elegance of the artificial legs.
Patients are helped tremendously to cope with everyday life in a new way, when recieving prostetic replacements. After therapists succeed in restoring their motor skills by means of high-tech prosthetic components, it is key to bring back the natural beauty of a human leg.
Lucky enough to have the opportunity to gather first hand experience in 2015 in the field of orthopedic mechanics during my internship at center for Design and Meteorology at SENA in Bogotá, Colombia, I analyzed the opportunities of industrial design in the field.
A negativ of the stomp is created to be filled with plaster to replicate the stomp and prepare the socket for the prostesis.
Making use of cutting edge technology, we used 3D scans to ehance existing products and digitize the craftmenship created at SENA, to be replicated over and over again.
The mission for the pre-diploma was clear.
A fashionable cover, that replicates the humanity on the replaced extremity.
3D Scanning and mirroring the healthy leg, to generate a twin cover.
Of the shelf components are very expensive and therefore standardised when it comes to form factor and Color, Material and Finish. Individualising the leg again is the goal of this project.
A common prosthesis with a Genium knee joint and carbon foot. Two mounting rails for the thigh section are mounted in the shaft. Corresponding recesses can be seen in the membrane above. In order to attach the cover to the prosthesis, the mounting rails are attached to the lower tube. The membrane with the respective recesses should be made out of a preformed latex stocking. Connections for the calf, shin and knee covers are incorporated into the membrane and pulled over the prosthesis together with the membrane. An aluminum core is embedded in the rigid mold rings, which ensures that the shape remains constant and provides sufficient resistance for the covers to be attached.
The membrane is pulled over the prosthesis, the grey retaining ring and the friction on the shaft hold the membrane in position at the top. In the foot, there is also a holder for the lower ring in the ankle area. The shaped rings incorporated into the membrane with the holders are attached to the holding rail on the prosthesis, thus ensuring that the membrane retains its shape. If all devices are attached, shin, knee and calf covers can be attached. The rubber lip in the covers is recessed in the places of the fastenings with the form rings. This way they can be inserted smoothly into the system.
