Method Company offers a collection which contains a large number of inventive problems (problem situations). The collection includes problem situations from TRIZ and other sources. A number of problem situations have been developed by Method experts and never published before.
The collection is helpful in conceptual design and TRIZ classes. It can be used by engineers and inventors for self-studying the above methods.
The problem situations mostly contain control answers, with some of them studied in detail through parametrical and combinatory methods.
