ABSTRACT
Throughout the history of human knowledge, there have been two conceptions concerning the law of development of the universe, the idealistic conception and the materialistic conception, which form two opposite world outlooks. TRIZ ideology is based on two major ideas; Contradiction and Ideality. Contradiction is the basic law of materialist dialectics, whereas ideality is the essence of idealism. These two opposite philosophic approaches are united in TRIZ, which uses their mutual cooperation. Perhaps this amalgam predetermines the unique power of TRIZ. The concepts of Ideality and/or Contradiction should be consciously included in any process of solving inventive problems. Hence this chapter and several following consider these main TRIZ concepts.
