With our app, you have the 40 innovation principles available at all times, as well as the contradiction tables for the technical contradiction according to Altschuller and Mann (2003) and the assignment of the innovation principles to the separation principles for processing the physical contradiction (according to Litvin). In the current release of the 40 IP app, you will find 559 examples, significantly more than in the last revision. And: The app is now free of charge.
I would like to reach as many TRIZ enthusiasts as possible with the app and constantly expand and improve the data. If you would like to contribute new examples, better pictures or drawings, that would be very welcome!
The app is displayed in English or German, depending on the system language on your cell phone. You can find the app here.
