Product engineer is being required to design attractive products in a short product development cycle from stakeholder. And, its attraction is influenced a great deal by idea creation in a conceptual design phase of this cycle. Therefore, FSA/SEV (Function Synthesis Approach with Simplification, Estimation and Validation) process has been developed. This systematic process is composed of four phases. First, the combination of large number of function is created from FSA. FSA become a conceptual design support tool that combines the PSO (Particle Swarm Optimization) and the particle method of USIT. Second phase, the combination of large number of function is simplified by the independence axiom And, the design solution is built by function structure method. Third phase, it is estimated cost of the design solution by using UCP (Use Case Points) method. Finally, it is validated quality of the design solution by using 1DCAE simulation (AMESim). However, FSA/SEV process cannot re-create a better design solution Because, FSA does not reflect the evaluation results that obtained by the estimation phase and validation phase. To solve this problem, this paper proposed a method that reflects the evaluation results that obtained by the estimation phase and validation phase. And, this paper described these phases via example to the refrigerator. As these results, we discuss effectiveness and plan future works for the much further improvement.
