Abstract:
Generally, the mechanism of "Wheelchair with Standing and Tilting Functions" has 2 degrees of freedom. In this paper, by using the checklist method (SCAMPER), the mechanisms with 1 DOF are invented to achieve the standing and tilting functions. Then, according to the dimensional synthesis, the dimensions of “Wheelchair with Standing and Titling Functions” are synthesized, the engineering design is accomplished, and the corresponding prototype is manufactured to verify the theoretical results. Two conclusions are derived as follows: (1). The new mechanisms invented have 1 degree of freedom (DOF) and use one power source to achieve the standing and tilting functions. (2). The centers of gravity of the new wheelchair after standing and tilting are still between the front and rear wheels, so no auxiliary wheels are needed.
