Abstract
A cordless screwdriver is a type of power tools available in the market, purposely used for fastening and drilling task powered by a rechargeable battery. In the design process, the designer is required to identify the possible changes of some issues found on the cordless screwdriver development emphasising cost, number of parts, materials, manufacturing process and the life cycle of this product. Thus, this research work towards focusing on the analysis of Cordless Screwdriver to minimise the components and to improve the design sustainably. Design for Manufacturing Assembly (DFMA) and Life Cycle Analysis (LCA) was utilised in this study. Analysis has shown how the number of components has been reduced to 15 per cent after the DFMA application. While the LCA has demonstrated a reduction of weight to 12%, air acidification is 8% and total energy 13%, carbon footprint 6% and water eutrophication is 6%. This new approach is important to demonstrate the efficiency of both to reduce the costs of producing a Cordless Screwdriver.
