Mobile idli-vada vendors provide a much-needed and affordable breakfast for the local urban public traveling across an area on foot, serving local shopkeepers and factory workers. Existing studies maintain that unhealthy posture, repetitive motions, and weightlifting are contributors to musculoskeletal disorders and lower back pains in 50–70% of vendors. The proposed solutions by these studies are in the criteria of policy-level changes and enhancing the consumer experience. This study’s objective is to analyze the ergonomic risk factors, derive design parameters and propose a design intervention that would help them in their daily tasks. The methods included using different ergonomic assessment tools like REBA, WERA, QEC, NIOSH, and NMQ and were conducted on 10 of these vendors. The findings reveal that perceived pain points were mostly in their shoulders, lower back, and neck muscles. It was also found that they have an underlying need for a design solution that is affordable and will assist them in their daily tasks. The study provides an overview of a possible product design to lower bending angles and enhance mobility for mobile vendors, benefiting others with similar tasks.
