In order to formalize and automatize the use of TRIZ based patterns, and in particular, the use of contradictions, a Generalized System of Contradictions (GSC) has been proposed. The model has been defined to always satisfy the existence of a GSC for unsolvable problems. It has also been stated that for a given problem, many systems of contradictions can be formulated. And so the question of the choice of the GSC to consider for resolution has to be tackled. In this article, a method will be proposed to illustrate that classical TRIZ contradictions do not exist systematically, but that in this case, Generalized Contradictions could be formulated. The hypotheses to hierarchize the contradictions will be proposed. The problems related to the use of the GSC will be detailed and a method to go from simulation until inventive problem resolution will be proposed. Finally, the existence of particular contradictions, contextual contradictions, will be illustrated, as they enable the application of TRIZ resolution principles.
