A recent study from the University of Waterloo highlighted the challenges faced by taller and shorter riders when it comes to motorcycle ergonomics. The study utilized a digital human model (DHM) to simulate realistic motorcycle riding behaviors and explore the joint adjustments needed for riders of varying statures to achieve their preferred riding posture. Taller riders were found to require more flexibility in their ankles, knees, hips, and elbows to interact with the motorcycle effectively, while shorter riders had limited options in joint angle configurations to reach the seat, handlebars, and foot pegs simultaneously.
The use of DHMs in early motorcycle design could help manufacturers improve safety, posture, and comfort for riders of different sizes while also saving costs by eliminating early trial and error steps. Justin Davidson, a Biomechanics PhD candidate at Waterloo, emphasized the potential benefits of incorporating DHMs in the design process to enhance overall ergonomics and accommodate individuals who fall outside the average size range. By studying avatars with various weights, heights, and sexes within the DHM, companies could tailor their designs to better suit a broader range of riders.
Despite the increasing popularity of motorcycle riding worldwide, the ergonomics of motorcycle design remains a relatively underexplored area. Davidson noted that motorcycle design companies are looking into technologies like DHMs to gain a competitive edge as motorcycle sales continue to rise. While DHMs are not as commonly used as they could be, their potential for early design intervention could extend beyond motorcycles to car seating and office ergonomics, ultimately improving safety and comfort for users at an earlier stage of the design process.
The goal of the research is to advance the field of ergonomic design and encourage the more confident use of DHM tools to intervene and enhance the user experience across various products and environments. By leveraging DHMs to address the specific needs of different user groups, companies can create more inclusive and accommodating designs that prioritize safety and comfort for all individuals. Through continued research and development in this area, the hope is to establish a more proactive approach to design that prioritizes user well-being and makes everyday experiences more comfortable and enjoyable for people of all sizes and shapes.
