The mathematical optimization techniques require extensive domain (physical understanding and accurate mathematical model) knowledge to design systems performing the desired functions optimally. However lack of domain knowledge makes the whole exercise futile as the mathematical optimization in such form does not account for all the possible means to accomplish the desired objectives. The situation becomes more complex due to the nature of objectives which are often contradictory. In such situations experimental optimization using Design of Experiments is applied which requires intensive experimentation on the prototype of the designed system. However, at the concept generation stage of the design process, the use of optimization approach which is based on the concept of increasing the ideality of the system is preferable. It ensures that the contradictions are resolved and the harmful functions are identified and reduced. In the present paper the characteristics of the optimization approach is demonstrated by considering the design of a mechanical system. As a case study design of valve system is carried out. The disadvantages of the conventional optimization approach are highlighted and a systematic and scientific procedure for design of valve system using optimization approach is presented.
