The following sorting options were and are available in the 40IP app: You can select the technical contradiction using the Altschuller Matrix or Matrix2003.
Another option is sorting according to Fayer’s group classification.
Or you can arrange the proposed principles for resolving the physical contradiction according to Simon Litvin, in line with the prevailing doctrine of MATRIZ and MATRIZ Official.
I-TRIZ (Ideation-TRIZ) uses a slightly different sorting method based on the research of Boris Zlotin and Alla Zusman. Ideation also recognizes other directions for resolving physical contradictions besides space and time, which do not entirely coincide with those of Simon Litvin. The classification is described in the books on MATRIX2003 and MATRIX2010. You can now select the sorting option “Physical Contradictions (Zlotin/Zusman)” in the app.
A new feature is the option to display the strongest principles regardless of contradictions (frequency of use), which are used by Pavel Livotov and Vladimir Petrov in their publications.
The database now contains 570 examples, and we are continuing to revise the examples and the images accompanying them. The examples were compiled together with students from various universities and are sometimes only line drawings. We are endeavoring to gradually replace these with better images.
The app is available in German and English. Depending on the language setting on your phone, the app will use either German (if German is set) or English (if any other language is set).
We have also changed the naming of the versions: The version number is now always the year, and the second number is the version within that year.
You can find the free app in the iOS App Store here.
You can download the app from the Google Play Store here.
