When we are given a design problem we try to make the best use of our knowledge and the available information to understand the problem and generate as many feasible solutions as possible. Then we evaluate these concepts against the customer s requirements and select a most promising concept for design analysis and design optimization. We may think of the design as a mapping of the customer s requirements into a physical embodiment. The better we understand the problem associated with the customer s requirements the better design we can achieve. The design process can be logically divided into three interrelated phases 1 product specification and planning phase 2 conceptual design phase and 3 product design phase. During the product specification and planning phase we identify the customer s requirements and translate them into engineering specifications in terms of the functional requirements and the time and money available for the development and plan the project accordingly. In the conceptual design phase we generate as many design alternatives as possible evaluate them against the functional requirements and select the most promising concept for design detailing. A rough idea of how the product will function and what it will look like is developed. In the product design phase we perform a thorough design analysis design optimization and simulation of the selected concept. Function shape material and production methods are considered. Several prototype machines are constructed and tested to demonstrate the concept. Finally an engineering documentation is produced and the design goes into the production phase. However if the concept selected for the product design is shown to be impractical it may be necessary to go back to the conceptual design phase to select an alternate concept or to .
