The main structure uses the design of the ellipse trochoid of the 4 bar strider. We made the ellipse trochoid to be the optimum state for reaching the simulation effect when people are running. Besides, the design can switch to be a new six-bar strider. It uses a link bar to bind the axis pillar and the pedal also made the pedal slide free to reach the sport effect.

研究内容主要著重於二合一椭圆机之椭圆轨迹最佳化及机构运动合成，主要构造系利用一四连杆椭圆机之设计方式，并将其椭圆轨迹最佳化，以期更符合模拟人跑步时的步伐；另外，此设计亦可转换为一新型之六连杆踏步机，其系利用一连杆连接踏板及中心柱，并使踏板可在滑槽上自由移动，使其可达到踏步之运动效果。
