| Abstract | Product design is one of the most important factors to introduce the circular economy model. In this discipline, the decisions made influence the whole life cycle of the product, since the raw material obtaining to the end of life of the product. Product engineering uses resources, both technical and material to create products. In this way, among all stages that product design encompasses, most relevant and significant decisions are taken during the conceptual stage, when changes can more easily be introduced. On the other hand, creativity plays an important role in introducing new features in products (as circularity is) in a new way. To implement in a proper manner these new functionalities in the products the concepts have to be evaluated. There are methods for assessing novelty and for assessing circularity, but in the case of circularity they are focused on products that have already been developed. Moreover, these methods do not assess circularity in a holistic way, as they only cover some of the aspects that the circular economy encompasses. This work intends to fill the gap that currently exists in the tools for evaluating product concepts by designing a metric, CN_Con, that measures the circularity and the novelty of conceptual proposals as a whole. The metric works according the product functions and analysing the novelty, the strategies for durability and for extending the useful life of the product that the concepts use. It also assesses the raw material and the end of life of the materials with which the concepts are designed. The development of CN_Con will help to implement the circular economy paradigm while encouraging creative design solutions. |
