Redesigning of Shopping Cart for Cost Reduction Using DFMA

Product Design is a way of creating new designs for various products to be sold by a business to customers. It is very efficient as certain new designs and ideas can lead to products with less cost. The two methodologies of design for manufacture and assembly (DFMA) include design for manufacture (DFM) which is concentrated on reducing the number of redundant parts for the ease of manufacturing and also design for assembly (DFA) which is concentrated on reducing the assembly time of the parts included in the design of the product. It also helps to reduce the inefficiency and waste in the product design. This paper includes a case study of manufacture and assembly costs estimation of a shopping cart which is widely used in supermarkets, department stores all around the world. The main aim of this paper is to reduce the overall manufacturing cost of the shopping cart. The CAD model of the different parts of the shopping cart was generated using solid works and then analysed using the DFMA software. The outcomes were studied and the re-design is done. The final assembly cost of the re-designed product was compared to that of the existing design and the results are discussed
