Chapter
For two decades, TRIZ has been considered as an inventive approach without rival in the existing design methods. It owes its originality to the work of Altshuller and his colleagues who compiled a large amount of scientific and technological data from all domains to build generic meta-models that inspire its users. But in its history, TRIZ has also...
Chapter
Extracting information from patents using machine learning algorithms in the context of TRIZ still faces a major problem: the very limited amount of annotated data. Therefore, most approaches, whether for parameter, problem or solution extraction, are based on unsupervised learning algorithms such as Latent Dirichlet Analysis (LDA), or very small s...
Chapter
Nowadays, Altshuller contradiction matrix is used by many TRIZ practitioners, especially by beginners, thanks to its simplicity. However, establishing the link between user’s specific problems issued from their experience in their domain of knowledge makes the use of the matrix often difficult. Applying specific terms of domain to formalized langua...

Chapter
It is well known that ARIZ constitutes the paradox of being the most powerful tool of TRIZ but also the least used. This lack of enthusiasm for its use is largely due to its apparent complexity and the feeling that this tool remains the prerogative of experts. Its algorithmic nature has questioned us to the point of investigating whether, today, mo...
Chapter
Full-text available
Inventive Design Method mostly relies on the presence of exploitable knowledge. It has been elaborated to formalize some aspects of TRIZ being expert-dependent.

Innovation is a key component to the success and longevity of companies. Our research opens the ‘black box’ of creativity and innovation in R&D teams. We argue that understanding the nature of R&D projects in terms of creativity/innovation, efficiency/inefficiency, is important for designing education policies and improving engineering curriculum....
Conference Paper
TRIZ has been lately used to find inventive solutions to inventive problems. In nowadays context, open innovation is felt as being an alternative to a “stand-alone” thinking way (even at the scale of a company) and as such, is claimed as more powerful than methods inspired by corporately organized brainstormings. It is evident that TRIZ and Open In...
