基于无意识设计理念的地铁车内扶手改良设计

Improved Design of Subway Interior Handrail Based on Unconscious Design Theory

目的针对现有的三类典型地铁车内扶手使用中存在的问题,通过观察乘客群体的无意识行为,分析研究乘客群体在乘车过程中的无意识需求,从而提出一种扶手及抓握件的改良设计方案。方法基于日本设计师深泽直人提出的无意识设计理念结合使用行为分析方法,通过分析站姿地铁乘客的无意识动作和实现抓握行为的有效性入手,研究地铁车内扶手的可用性和舒适性,发现车辆运行方向的加速度带来的瞬间冲击是地铁抓握件应当主要克服的作用力。结论提出地铁车内扶手及抓握件应当首要解决的实际问题,并按照这种思路尝试提出一种符合乘客群体无意识需求的合理改良设计方案,该方案具有较好的人机使用特性,对于地铁车内扶手的设计具有一定的参考价值。

The work aims to analyze and study the unconscious demands of the passenger group in the process of riding by observing the unconscious behavior of the passenger group and then propose an improved design scheme of handrails and grasping parts in view of the existing problems in the use of three types of typical subway handrails.Based on the unconscious design concept put forward by the Japanese designer Naoto Fukasawa and in combination with the behavior analysis method,the usability and comfort of subway handrails were studied by analyzing the unconscious actions of subway passengers in standing posture and the effectiveness of grasping behavior.It was found that the instantaneous impact caused by acceleration in the direction of vehicle movement was the main force that subway grasping parts should overcome.The practical problems that should be solved first for the handrails and grasping parts in the subway are put forward,and a reasonable and improved design scheme that meets the unconscious needs of passengers is proposed based on this idea.The scheme has good man-machine performance and provides certain reference value for the design of subway handrails.
