To support better rapid response product design, a reconfigurable design method for product module based on function-principle-behavior-structure (FPBS) was presented. For design requirements of expectant module, the iterative mapping method based on FPBS was adopted to establish the FPBS-based decomposition model of existent module. Afterwards, based on FPBS model of existing module, approaches including function reconfiguration, principle configuration, behavior combination, and structure polymerization were carried through, so as to construct dynamic model of expectant module. Furthermore, by structure integration and design, module reconfigurable design was realized eventually. Finally, this method was applied to reconfigurable design of stacking crane’s push-puller structure, which doubling push-puller structure was transmuted into quadrupling push-puller structure, and the feasibility and validity of the method were proved.
