Abstract: To improve the efficiency of innovative design and performances of a product, a self-commentary design method facing product-oriented innovation and fuzzy back end evaluation was proposed. Firstly, a functional structure mode of product was built on the basis of axiomatic design theory. The contradiction matrix must be built and the initial scheme should be redesigned by TRIZ conflict analysis method in order to be decoupled, and got product innovation program. Lastly, taking the lower extremity exoskeleton robot as an example, the structure was decoupled and optimised using Altium Designer (AD) and TRIZ theory. The performance of the lower extremities exoskeleton robot was evaluated quantificationally by using fuzzy analytic hierarchy process, which verified the feasibility and effectiveness of the decoupling design and fuzzy back end evaluation method for product innovation design and inspection.
