- Interview with the client to ask the specifications and expectations of what is needed to design and establish a device for wheelchairs that offer different methods of prevention for pressure ulcers on individuals who use wheelchairs.
- The team performed research on the background of the leading causes of pressure ulcers on various parts of the body due to sitting in a wheelchair or bed for extended periods of time.
o Pressure
o Friction
o Shear
o Temperature
o Lack of blood flow
- Furthermore,
research was also done on the current technologies available that exist
that aid in the prevention of prevention of pressure ulcers.
o Passive
support: cheaper than active support. Materials that conform to the body,
reducing pressure by increasing the contact surface area. Materials include
foam and sheepskin, as well as gel, fiber, air, water, and bead-filled
cushioning.
o Active
support: measurable pressure, circulation, and climate-regulating advantages
over passive supports.
- The team created a FRDPARRC table to establish different functional requirements of the assistive device and the design parameters, analysis, references, risks, and countermeasures to those functional requirements
