Abstract
In this research, patent maps were first drawn by searching, organizing and classifying those patents related to bicycles' capabilities and technologies, and the direction of improving and inventing folding bicycles was found out with the patent maps. Next, the methodology of TRIZ was applied to analyze the problems; the basic technological contradictions were confronted, and the resolve program was developed. In the end, an improved folding bicycle was designed, using PRO/E, the drawing software, to complete the product's blueprint.
