Abstract
In a previous study, the author proposed an overall organizational creation model for product concept uncertainty in the P2M scheme model. The scheme model incorporates a conception model based on the actions of “ analogical modification “and “ inspiration and reflection “ in the creation of product concepts, and is a mechanism to enhance the conception of the idea throughout the entire organization. This paper examines in more detail the concept design model based on the actions of “ analogical modification “and “ inspiration and reflection “ which can be called the engine of ideas in this model, from the perspective of the relationship between analysis and synthesis, and presents its synergy effects and correlation with the concepts generated. Through case studies, the usefulness of the model will be clarified and directions for future research will be presented.
