This document discusses innovation and structured approaches for innovation. It introduces TRIZ, a problem-solving method developed in the Soviet Union that is derived from patterns of invention in patents. TRIZ is based on the idea that problems have already been solved before, so creativity is about finding those solutions and adapting them. The document outlines TRIZ's approach of analyzing problems, finding related solutions in databases, and developing specific solutions by thinking analogously. It describes two categories of contradictions that TRIZ aims to eliminate - technical trade-offs and inherent contradictions. Finally, it presents the 40 TRIZ principles for solving contradictions innovatively.
