Abstract: To reflect the dynamic parameters evolution of complex electromechanical system,the digital twins was introduced into the innovative design process of complex electromechanical systems.The digital technology was used to descriptive modeling the characteristics,behavior,formation process and performance of physical objects.The design parameters and system failure parameters obtained by applying TRIZ failure prediction tool were introduced into the digital twin model for parameter evolution,and then the potential problems in the design and manufacturing process were found.By applying TRIZ and digital twin technology to the conceptual design stage,the design parameters and failure parameters in the design process were extracted and the parameters evolution was applied to the digital twin technology to serve the whole life cycle of complex electromechanical system.The design example of dense cabinet intelligent three-dimensional parking device was given to verify the scientificity of the proposed method.

Key words: digital twin, TRIZ theory, deduction parameters, anticipatory failure determination, innovative design, dense cabinet intelligent three-dimensional parking device
