This paper presents a comprehensive analysis to examine the effectiveness of the Boothroyd Dewhurst Method for
Assembly that is used to enhance the product design process. The Design efficiency of Lamp holder B22 was calculated by
analyzing the number of necessary parts, manual handling time and manual insertion time. The product is then redesigned,
considering the manufacturing and assembly aspects and a comparative study using Boothroyd Dewhurst Method was carried
out between the original design A0 and modified design A1. Therefore, the modified design of Lamp holder was proposed to
increase the design efficiency by minimizing the number of parts and incorporating multiple parts to single part. As a result, the
design efficiency of modified design of Lamp holder has increased from 20.23% to 24.73% of around 4.5%.
