When invention creates needs for innovation in the field of understanding and treating pelvic diseases}, AUTHOR={Cédric El Maleh, Dominique Vinck, }, JOURNAL={Technology and Innovation}, VOLUME={4}, NUMBER={Issue 4}, YEAR={2019}, URL={http://www.openscience.fr/Collateral-innovation-When-invention-creates-needs-for-innovation-in-the-field}, DOI={10.21494/ISTE.OP.2019.0412}, ISSN={2399-8571}, ABSTRACT={Innovation often takes root in the invention of an original solution to a given problem. In the case of the innovation process discussed in this article, the story indeed begins thus. Doctors confronted with a health problem, to which they are struggling to find satisfactory solutions, turn to mechanics in order to work together to find an innovative solution and then disseminate it. This article reports on the trajectory of their cooperation. The article shows that detours and unexpected innovations are not simply by-products but also play a role in the dynamics of innovation as they unintentionally contribute to preparing the demand for the innovation that was initially expected. The article thus helps to account for the complex temporalities of innovation and for dynamics that are far from linear. Moreover, the fact that the actors are teams of collaborative researchers, no member of which emerges as a hero of the story, helps to account for the actors who are often left in the shadows. This article reports on the socio-technical thickness of an innovation’s way of life and how it can fit into an environment that it has also helped to shape.}}
