A novel method for conceptual design of a mechatronics system was proposed, and the design framework of “requirement-environment-conflict-original understanding-solution” was established. The contradiction between design requirements and environmental constraints was identified by using the method of environment-based design (EBD), and the requirements and environment were iteratively analyzed to decouple complex and abstract issues. According to the original understanding of the theory of inventive problem solving (TRIZ), the product solution for specific needs was obtained, which ensured the directionality of innovation, the systematic generation of product design solutions, and the standardization of the design process. The friction and wear test machine of the aeroengine variable stator vane (VSV) shaft bushing system shows that the proposed design method is reasonable and effective.

Key words: environment-based design (EBD), theory of inventive problem solving (TRIZ), integrated design, innovation method
