Research and application: conceptual integrated model based on TRIZ and bionics for product innovation

TRIZ and bionics are two techniques for systematic innovation that can help designers achieve innovative product solutions. In order to help the designer to determine conflicts happened in the design of product, an adapted TRIZ method is proposed. Bionics is a new developing frontier science permeating and combine biology, mathematics and engineering studies, and the designer can attain a innovative solution by adapting bionics method. This paper describes a interactive model by integrating TRIZ tools with coupling bionics. Firstly, a new table of inventive principles based on biological function is presented, and the human–computer interaction query interface was designed by MATLAB tool. After design conflicts in product system are determined, designer or group of ideation chooses from the bionic template which is attained according to the conflict Matrix 2003 in TRIZ, The biological tree model is built to analyze biological coupling elements of the bionic template, and then analytic hierarchy process is applied to figure out the main and hypo-main coupling elements. By imitating functions of the main and hypo-main coupling elements, different kinds of bionic coupling models for product can be established. Finally, the designer can evaluate and judge whether the innovative solution is optimal or should be returned to design.
