Abstract：To solve the existing problems of less satisfaction of wrist joint rotator, use the optimized third creating method of extenics, construct an improved design model of rehabilitation products. Firstly, two kinds of function trees are introduced to improve the defect listing process to quickly locate defective components; Secondly, rehabilitation knowledge, man-machine data and modeling sample matter-element were added to constrain the expansion and transformation process of matter element optimization to improve the efficiency of extension transformation, Take E enterprise wrist rotator as an example, 5 defective components and 4 missing features were improved. At last, establish an evaluation system, product was evaluated before and after, which verified the feasibility of the process model.
