The Contradiction Table, which is used together with the 39 Parameters allows to model a technical system under improvement. It offers a problem solver with a set of Principles (out of the 40 Innovative Principles) that were the most effective to solve similar problems in the past (i.e. for the solutions found in the 20,000 patents that were analysed).
It is anticipated that the comprehensive set of educational materials for teaching and self-learning of the Contradiction Table modelling will be available by 2019. At the moment the reader can download the list of the 39 Parameters as well as the Contradiction Table (provided by TRIZ4U).
