PRODUCT DESIGN IMPROVEMENT OF A MULTIFUNCTIONAL WHEELBARROW

Abstract

This study was conducted to redesign a wheelbarrow commonly used in workshop environments, focusing on improving efficiency, safety, and ergonomic handling during the transportation of heavy loads. The original design was found to have several limitations, including low stability, difficulty in manoeuvring within confined spaces, and discomfort due to poor handle placement and unbalanced weight distribution. The main objective of this study was to address these issues by developing a more user-friendly and practical design that suits real workshop conditions. The methodology involved analysing the existing design, developing a new model, and conducting performance testing in an actual workshop environment. Performance was assessed through physical observation, measurement of load transfer time, and user satisfaction surveys. The results showed significant improvements in handling, load stability, and user fatigue reduction. The new design also contributed to reduce task completion time and smoother movement across workshop areas. In conclusion, the study demonstrates that redesigning basic equipment like the wheelbarrow can significantly improve work effectiveness, enhance safety, and provide greater user comfort in daily workshop operations.
