Abstract

A mechanical device to control kart’s tire pressure was developed. This valve must blow air when temperature’s tire and pressure rise with a not acceptable shape deformation and a corresponding modification of the vehicles trim. With the new solution, drivers can drive faster and more safely. Two design methods have been utilized: QFD and TRIZ. The first one, Quality Function Deployment, offers a clarification tool for organizing the information flow in a structured way, and TRIZ, Theory of Inventing Problem Solving, is an efficient tool in the discovering the solution principles. With TRIZ’s Table, technical and physical contradiction are put in evidence and eliminated to improve the robustness of the device. The two methods interact one another and offer the best path for the development of a new design.
