Design and Fabrication of a Pedal-Operated Washing Machine for Off-Grid Rural Households

Objective: To design, fabricate, and demonstrate a low-cost, manually operated washing machine suitable for off-grid rural communities in India.

Rural households in India often lack access to reliable electricity and affordable washing solutions, leading to significant manual labor and time spent on laundry, predominantly affecting women and children.

This project aims to engineer a pedal-powered washing machine that operates without electricity, using a robust mechanical drive and locally available materials to ensure easy maintenance and affordability. The team will analyze existing manual washing devices, optimize the drive mechanism for minimal effort, and design for ergonomic use in typical rural settings.

Key features include a chain-and-sprocket pedal drive, sealed drum with agitation mechanism, simple water inlet/outlet system, and corrosion-resistant frame. Deliverables comprise detailed CAD drawings, a fabricated working prototype, cost analysis, user manual, and live demonstration of washing performance using real loads.

This solution promotes sustainable development and empowerment in resource-constrained areas, reducing drudgery and water consumption. The model is scalable through local manufacturing, potentially benefiting NGOs, self-help groups, and rural entrepreneurs.
