摘要:

疲劳驾驶预警系统是减少交通事故发生并加速智能交通建设的重要一环。以优化和扩展现有系统的功能为出发点,针对系统在不同时序阶段所需功能可能不同的情况,从概念设计阶段将疲劳驾驶预警系统、TRIZ理论与专利规避相结合,通过改善九屏幕法分别以过去、现在、未来的角度对目标系统的功能进行分析,融合成一种基于专利规避的疲劳驾驶预警系统扩展概念设计方案。该方案在专利规避层面成功规避原有的专利方案,在概念设计层面扩展并改善了原有概念方案的功能,并以疲劳驾驶预警系统为例验证了方案的可行性。

Abstract:

The driver fatigue monitor system played a crucial role in reducing traffic 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
