Design, Simulation and Fabrication of an Ergonomic Handgrip for Public Transport in Bangladesh

Abstract

Many individuals in Bangladesh prefer using private vehicles to avoid the discomfort of public transportation, causing significant congestion during rush hours. To ensure a pleasant journey in public transit, including safe and comfortable handgrips becomes crucial. This study adopts a comprehensive approach to alleviate the discomfort and hand fatigue experienced by public transport commuters in Bangladesh. Our research methodology thoroughly analyses existing handgrips with a diverse age group (11-50) and varied occupational backgrounds, ensuring inclusivity. Meticulously collected anthropometric data from previously published works incorporates the 95th percentiles to account for diverse hand sizes. Leveraging computer-aided design tools, we optimize the hand grip design based on ergonomic principles and hand anatomy. Our study fills a crucial gap by integrating locally derived anthropometric data. The resulting ergonomic hand grip, designed for the specific needs of Bangladeshi commuters, is poised for seamless integration into the public transport system, promising a substantial improvement in comfort and a more positive commuting experience.
