Integrating DFMA to sustainability and FEA assessment: Case study of portable bluetooth speaker

Abstract

Bluetooth is a well-known technology producing short-range wireless links that enables a short distance from two or more devices. This article focuses on improving the assembly process and its effect on the environment using DFMA and sustainable design on portable bluetooth speakers. However, the problem regarding this speaker is it comes box-shaped that is outdated and bulky. It also does not resistant to water as it is limited to dry places only. The objectives of the research are to re-design a much compact and sleek looking portable Bluetooth speaker and to ensure the speaker to be water-resistant. In addition, DFMA is used to minimising the quantity required, and SolidWorks@ software is applied to evaluate by comparing different materials and four environmental factors such as carbon footprint, water eutrophication, total energy consumption, air acidity as well as material financial impact.
