The assistive technology is lack of sufficient fund in researching, and evaluations of ergonomic engineers and machinery designers in Taiwan. Presently, academic research works on stair-climbing mechanism and most of them are still at the developing stage. Commercialized products are with complex structure and high price so that they are not popular for the users. The objective of this research is to design the stair-climbing mechanism which is expected to provide simply-constructed, and precise in movement. This research collects kinds of stair-climbing mechanism from patent and literature for classifies and analyses that provides excellent references to design of future stair- climbing mechanism. Therefore, the problem is analyzed systematically to improve the stair- climbing mechanism by innovation design. Making survey from the customers through Quality Function Deployment (QFD). It is effective way to transforms the product function and characteristic, so the problem can be found and improved fast. Finally it will unify Theory of Inventive Problem Solving (TRIZ), the method to improve creativity question. Using contradictory matrix table to obtain design concept and suggestion that from various aspects will be consider. Result of the research defers to the suggestion of TRIZ analysis, it still has the further innovation improvement regarding the functional design of stair-climbing mechanism. Using SolidWorks build the 3D model. Furthermore, COSMOSMotion for kinematics simulation, COSMOSWorks is used to analyze stress, stain, and displacement, so as to confirm the intensity of the stair-climbing mechanism designed. This reserch use these methods to design the stair-climbing mechanism. That use smaller motor than befor stair-climbing mechanism to climing stairs. To design the new stair-climbing can load 200 kg. The scale stair-climbing carry more than 70kg from 60kg after mount the spring.
