本研究主要目的在於利用一套系統化的設計方法來設計新型橢圓運動機。文中首先分析專利文獻中的現有橢圓運動機之機構構造與運動特性，進而歸納出橢圓運動機設計需求與設計限制;接著，根據橢圓運動機的構造需求，利用創意性機構設計方法來合成出可行的四連桿與六連桿橢圓運動機構造，並從中選定三個機構進行尺度合成;最後，根據所訂定的橢圓運動機之規格，以搜尋圖集比對近似曲線的方式，來合成出三個新型橢圓運動機的桿件尺寸。

　　The main purpose of the study is to design new elliptical motion exercisers by using a systematic method. First, the design requirements and constraints are concluded from the results of structural analysis and kinematic analysis of some present elliptical motion exercisers. Topological structures of the feasible elliptical motion exercisers with four- and six-link are then synthesized utilizing a creative mechanism design method. According to the kinematic requirements of the elliptical motion exerciser, kinematic dimensions of three new elliptical motion exercisers are synthesized by the method of curve searching.
