Abstract: Aiming at the complexity and dynamic characteristics of complicated electromechanical product design process, in view of fractal thought, the concept of fractal design unit was proposed by using design task-design parameter incident matrix to express product design process. According to the similarity and dynamic characteristics of fractal design unit, the fractal design unit model in design process was constructed. To obtain the fractal design unit model, initial incident matrix was used to find seed design parameter, to set allowable attraction coefficient, and decomposed circularly. A mechatronic joint in an auto-feeding machine was used to elaborate fractal decomposition process, and the result verified the feasibility of the fractal design unit model.

Key words: mechatronic product, design process, incidence matrix, fractal design unit, product design
