Modelling Industrial Design Contribution to Innovative Product or Service Design Process in a Highly Constrained Environment

The purpose of this study is to build an enhanced design model applied to the conception of an innovative product in an SME environment. This approach includes C-K theory in the context of innovation.In general, the industrial design process consists of four major steps:The ego-design phase, where the designer conceptualises a user needThe techno-design phase, where the designer and engineer find solutions to materialise the conceptThe eco-design phase, where the social actors involved authorise it and thenThe ergo-design phase, where the user adopts the final productA methodological reflection leads to the modelling of innovative enhanced design reasoning (where major actors are replaced by a bunch of various stakeholders).The specific SME’s case was successful. Using the model, the enhanced design project management was efficient. But some more complex application cases would help secure it. Using this approach, with appropriate information, should guide the SME design project manager in the general innovation process.
