Abstract: To satisfy diversified customers'requirements and achieve innovative design, product variant design was realized by changing the original structure of the variation base model. The existing Transplantable Structural Unit (TSU) was transplanted into entity, and a method to reconstruct the constraints among structures of the new entity after joining the two parts together was given. Design Structure Matrix (DSM) was extracted from constraint relationship among structures, then the DSM was transformed by adjusting the growing relationship and structures constraint, so as to guide variant design. Multi-granularity structural unit constraint reconstruction oriented to product variant design was finally realized. Secondary development was conducted by using VC6.0 under the UG environment, and an example of the key components design of injection molding machine was also provided.

Key words: variant design, design structure matrix, growing relationship, constraints reconstruction, injection molding machine, product design
