Abstract：In order to help designers generate innovative product solutions using TRIZ and bionics, which were two techniques for systematic innovation, a design process model by integrating TRIZ tools with coupling bionic technology was described. Firstly, a new table of inventive principles for biological functions was presented. Bionic templates were selected for solving conflicts in product using the conflict Matrix 2003, which was realized by Matlab tool. Secondly, the biologi- cal prototype tree model was built for making biological coupling analysis, in which analytic hier- archy process was applied to figure out the contribution of coupling elements. By imitating the main coupling elements and/or secondary main ones, different kinds of bionic coupling models for product could be established. Finally, the result of simulation was applied to determine whether the innovative model was better than the currently available ones. A case study of designing a fan blade model was used to demonstrate the applicability of the proposed approach. According to the result of simulation by Fluent soft, it turned out that for the bionic innovation model, the quality flow rate was increased by 6% and the grade A noise value was reduced by 2% in monitoring points.
