This article offers a methodological contribution for the standardization of engineering and systemic innovation with a view to supporting design teams in the development of eco-innovative products. We propose a unified methodology that will allow users to self-guide to create eco-innovative product concepts through the application of C-K theory combined with the TRIZ method while integrating the principles of the ASIT method. Firstly, understanding the links connecting the different sources of knowledge linked to the birth of eco-innovative concepts makes it possible to design one or more generic solutions. A simplified and adapted application of TRIZ will lead us to an eco-innovative solution. Thus, to refine the results, an AI algorithm will generate new solutions from the data and conditions recorded within the artificial intelligence.
