An integrated module division method based on the combination of axiomatic design and fuzzy dendrogram was proposed. The product was divided step by step using the framework of zigzagging map between the functional domain and physical domain of axiomatic design. In the case that the design matrix are diagonal matrices, the substructures of the division meet the functional and structural independence and can be considered as a separate module, then the division of module can be ended. When the design matrix are triangle matrices or fall rank matrices, the correlation of function and structure between the substructures were analyzed and then fuzzy dendrogram was used to cluster the substructures into modules. An example was used to illustrate the validity and rationality of the proposed approach.
