The Quick Design Method for the Big and Complex Products based on Function Disassembling

This paper gave out an analyst the condition, disassembling and unfold principle of module concept with the function planning and relationship, developed the process with the sample of leveling machine. It got the idea plan of the product, put forward the action of function disassembling and transit into the design by the quick industrial design sketch and rendering method, improved the efficiency of concept design. It get conclusion the modularity and disassembling method will guiding the designer and give a reference on the large and complex product function defining and design.
