Usually the inventive problems arise during the conceptual design. Known methods and theories of engineering design do not work for the inventive problems. In contrast TRIZ [1-3] handles such problems relatively well. A brief review of some important TRIZ concepts and detail description of a new glance to problems presentations are given along with a short discussion of possible links between TRIZ and knowledge-based AI systems. The important attributes of the inventive problems - their difficulty, structure and complexity - are outlined.
