摘要

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.

一般而言，“具站立和後傾功能輪椅”的機構具有2個自由度。本研究，首先利用檢核表中之（SCAMPER）方法，創造出可實現站立和後傾功能之1個自由度的機構；接著根據尺寸合成理論，合成出“具有站立和後傾功能之輪椅”的尺寸，並完成工程設計與雛型機製作，驗證理論結果。本研究成果如下：（1）.本研究創造出可實現站立和後傾功能之1個自由度的機構，並使用一個動力源來實現站立和後傾功能。（2）.本發明“具有站立和後傾功能之輪椅”，當站立和傾斜時，輪椅的重心仍然位於前輪和後輪之間，因此不需要額外的輔助輪。
