Abstract

Most professions nowadays demand extended hours of standing, which contribute to discomfort and Work-Related Musculoskeletal Disorders (WMSDs). The study aims to design and develop a collapsible and adjustable leg support and standing aid to alleviate the same issues by providing ergonomic support designed based on Anthropometric measurements for different individual users. The device was designed using anthropometric data from a comprehensive study involving 1,805 Filipino manufacturing workers. Design for extremes and design for an adjustable range were incorporated in the design process, making the device suitable for a range of users from the 5th percentile female to the 95th percentile male. By featuring a multi-point support system that includes lumbar, buttocks, and shin support, the device facilitates a semi-standing “Perching” posture promoting an open hip angle of approximately 135 degrees. Biomechanical simulations demonstrated that this configuration successfully offloads up to 60% of the user’s body weight from the knees and ankles. Furthermore, static load and stability simulations dictated the material selection process, ensuring the chosen material’s yield strength would provide a safety factor greater than 2.0. The gadget is simple to store and move because it is foldable and portable. This study emphasizes how crucial it is to incorporate Anthropometric information into ergonomic design in order to produce viable, user-centered solutions that improve comfort and health at work.
