Attributes of the Inventive Problems

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.
