Abstract: To realize better product's modular design， the module partition technology was introduced into the process of product's conceptual design based on Function, Behavior, conceptual Structure (FBS), and a FBS-based method and process model for product's conceptual module design were presented. The method of product's conceptual design was analyzed，which achieved the iterative transformation from function to behavior，from behavior to conceptual structure， from conceptual structure to sub function according to the product's general technology characteristics. To describe the conceptual product, the conceptual product's modeling method which combined Black Box method with function description of IDEF0 was presented to construct the product's function-conceptual structure model. Then, the correlation analysis approach for product's conceptual elements (function, behavior, conceptual structure， interface) was proposed. To realize the partition of product's conceptual module, the fuzzy clustering algorithm was introduced to converge product's conceptual elements. Finally, this method was applied to the conceptual design process of stacking crane's fork structure, and the effectiveness of the method was proved.
