This research is focused on clarifying the effect of providing information, where synthesis of different product components provides with an implication for generating new product ideas. We hypothesize that generating new product ideas is induced by unexpected assemblage of presented different product components. This hypothesis was evaluated by analyzing playing logs of a developed Web based tool to enjoy assemblage of elements whereof categories are consisting of three components, i.e., purpose, function and material. We defined generating new product ideas is associated with possible architectural compatibility. As a result of 11players, we found that generating ideas tends to be either visible products or invisible products as a service, depending on one’s attention to purpose at initial stage, e.g., the more purpose is considered, the more ideas are relatively visible products. In addition, the meaning of purpose has been interpreted as means to new product ideas.
