Product design is conceptualization of an idea about a product and transformation of the idea into a reality. To transform the idea into reality a specification about the product is prepared. This specification is prepared by considering different constraints such as production process, customer expectation, etc. In product design stage every aspects of the product are analyzed. Also final decision regarding the product is taken on the basis of the analysis. This decision can be any aspect related to the product, e.g. dimension and tolerances, type of material for every components, etc.
Product design is one of the most important and sensitive factor for an organization. Success or failure of the product decides company’s business, market share and reputation. So during design stage various factors related to the product needs to be addressed.
Research & development: Basic research is a search for new knowledge. It does not have any immediate application, but based on the basic research new product can be developed in future. Applied research has objective of developing commercial products.
CAD-CAM: By using 3D modeling software system, designers develop a computerized model of a new product and analyze its design parameters. After computer aided design (CAD), computer aided manufacturing (CAM) system produce the product by using CNC facility.
Concurrent engineering (CE): CE is different than conventional approach of design. In CE, different co-related teams are formed, which perform different activities for developing a product. For example, development of market concept, design of product, development of manufacturing process, selection and arrangement of material for new design is performed by different teams at the same time. It reduces considerable amount of time to develop a new product.
In practice different concepts are combined and applied together to design a new product.
