基于专利规避设计的疲劳驾驶预警系统扩展概念设计OA

The driver fatigue monitor system played a crucial role in reducing traffic accidents and ac-celerating the development of intelligent transportation systems.This paper focused on optimizing and ex-panding 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 cir-cumvention strategies from the conceptual design phase,the paper enhanced the nine-screen method to ana-lyze 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 pat-ent 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.
