CAD-system in solving design and inventive problems

Abstract

Abstract The paper discusses the issues of user interaction with the CAD system. The system approach requires the study of the third element - the interface. In addition to the classical subsystem of receiving, transforming and transmitting user requests, the interface model includes testing, statistical analysis and recommendation subsystems. The task of the first subsystem includes an assessment of the user's creative potential, the second reveals the user's preferences and the conditions for their use, and finally, the third subsystem should prompt the user that in some cases there are more convenient tools than the ones he prefers. Further, the first subsystem is investigated in more detail. The experiment was conducted on a group of students in the study of the discipline "Fundamentals of engineering creativity" using two types of tasks: spatial imagination and kinematic thinking. It is shown that, as a first approximation, users can be divided into two classes and force the CAD system to compensate for their one-sidedness, by adding creativity when making design decisions in one case and an analyst in another. Thus, on the one hand, the creative potential of its user develops, on the other hand, the user has the right to demand from the CAD system greater adaptability and intelligence in communication.
