The textbook is intended for students of higher educational institutions (primarily technical), but is also quite accessible to high school students, gymnasiums and colleges. The book expands the basic textbook "ABC TRIZ," but contains a sufficient introductory theoretical part (chapters 1-4) on primary models of the Theory of Solving Inventive Problems (TRIZ), as well as additional examples (chapters 5 and 6) and reference materials that allow you to independently use the book for practical work and, of course, for self-study.
