Week 3

During week three of class, sketches of possible designs were drawn up.  The three different designs can be seen by clicking on the Brainstorming tab above. Each design includes how it is meant to work.  However with each design there are constraints that need to be overcome.  Our main design is shown in Figure 1 and 2, an air ventilation system used in conjugation with a liner. Between the prosthetic and liner would be an layer that allows for air to circulate throughout and thus onto the skin that is in contact with the prosthetic directly. Several other ideas and designs have been created also. Figure 3 shows a liner that can draw the moisture and perspiration down into one collecting area. This collection area could then be emptied. Figure 4 is solely for lower extremities prostheses. A mechanical pump would be inserted to create air flow. The pump would be activated and thus air flow would occur by the natural forces of pressure created when weight is pushed down onto the prosthetic from walking.
