Abstract：The driver fatigue monitor system played a crucial role in reducing trafic accidents and accelerating the development of intelligent transportation systems. This paper focused on optimizing and expanding the functionalities of existing systems. The varying functionalities of the systems were addressed at different chronological stages. Integrating driver fatigue monitor system with TRIZ theory and patent circumvention strategies from the conceptual design phase，the paper enhanced the nine-screen method to analyze the target system’s functionalities from past，present，and future perspectives. This integration led to the development of an expanded conceptual design scheme for a driver fatigue monitor system based on patent circumvention. The proposed scheme successfully navigated existing patent frameworks at the patent to avoid level and extends and improves the functionalities of the original concept at the conceptual design level.The feasibility of the scheme Was demonstrated with the driver fatigue monitor systems as a case study.

Key words： driver fatigue monitor system; patent circumvention; TRIZ theory ; conceptual design
