Design and fabrication of a helmet washing machine

Motorcycle helmets are essential for rider safety, but their inner linings accumulate sweat, dirt, and bacteria over time, leading to hygiene issues and unpleasant odors. Traditional cleaning methods are often time-consuming and ineffective in reaching hidden crevices. This study focuses on the design and fabrication of an automated helmet washing machine to simplify the cleaning process. The machine incorporates a rotating nylon brush for scrubbing, a controlled water spraying system for rinsing, and a PTC air heater for drying. The design was developed using SolidWorks, followed by material selection and prototype fabrication. Mild steel was used for the structural frame, while aluminum composite panels were chosen for their durability and corrosion resistance. Structural integrity was evaluated using stress analysis in SolidWorks, and theoretical calculations were performed to determine the torque requirements for the rotating brush mechanism. The project successfully demonstrates the feasibility of a cost-effective and user-friendly helmet washing machine. While the prototype operates as intended, further testing is required to assess cleaning efficiency, drying performance, and long-term durability. Future improvements include optimizing water usage, enhancing the drying mechanism, and integrating an automated timer for improved user convenience.
