This paper investigates and analysing the reduction of the total number of car phone holder components and its possibilities towards the design sustainability. The analysis setup is used Design for Manufacturing Assembly (DFMA), Finite Element Analysis (FEA) and Life Cycle Analysis (LCA) for the purposes mentioned above. It was found that the total number of components was reduced by 67.9% using DFMA. Sustainability analysis proves that the redesign of the car phone holder was able to reduce the environmental impact throughout the overall design. The FEA analysis also revealed that the redesigned product could be support by the different weight of the phone load. This approach is essential to the designer and design engineer to identify product sustainability at the initial phase of the design process, especially during conceptual design for a better product.
