Design and Simulation Analyses of a Five-Wheeled Stair-Climbing Mechanism Based on TRIZ Theory

摘要

Based on TRIZ theory, a five-wheeled stair-climbing mechanism is designed. Its function and structure of the system are analyzed, and the contradiction analyses are made on the problem existing in the design process. The ideal final result is found by combining 40 inventive principles. Then, the five-wheeled stair-climbing mechanism is simulated and analyzed to verify the rationality and stability of its structure. The mechanism is small in size and simple in structure. It is suitable for general stairs and has a good practical value.
