Contradiction matrix teaching device based on theory of inventive problem solving (TRIZ)

Abstract

The invention discloses a contradiction matrix teaching device based on a theory of inventive problem solving (TRIZ). The contradiction matrix teaching device based on the TRIZ comprises a plurality of strip-type shells distributed in columns, the strip-type shells are connected in series through cables to form a bamboo slip mechanism capable of displaying a contradiction matrix table, the bambooslip mechanism is provided with table cells corresponding to all grids in the contradiction matrix table, a turnover mechanism is arranged in the table cell corresponding to a theory serial number grid, and a normally-opened touch switch and a laser transmitter are installed on the table cell corresponding to a general engineering parameter. The contradiction matrix teaching device based on the TRIZ is a bamboo slip type device which can be wound conveniently, using is flexible and convenient, occupied space is small, hoisting is facilitated, teaching is suitable, a display plate normally displays theory serial numbers in a natural state, the theory serial numbers on the end surface of the display plate cannot be observed after the display plate is overturned, and teacher questioning is facilitated; lasers are emitted through a first transmitter and a second transmitter, the crossing position of the two lasers is the theory serial number of a cross point of two general engineering parameters, students can conveniently learn, valuable teaching time can be shortened, and the teaching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a conflict matrix teaching device based on TRIZ theory. Background technique [0002] The conflict matrix is ​​also called the contradiction matrix. The contradiction matrix is ​​that Altschuler organically connects 39 general engineering parameters and 40 invention principles, establishes the corresponding relationship, and organizes them into a 39×39 contradiction matrix table. According to the results of Le's research on 2.5 million patents, the composition of the matrix is ​​very tight and self-contained. According to the two general engineering parameters that produce contradictions in the system, users can directly find out the inventive principles for resolving contradictions from the matrix table, and use these principles to solve problems. [0003] The first row of the contradiction matrix encodes the 39 general engineering parameters, and the second row cont...

AI Technical Summary

Problems solved by technology

[0005] In TRIZ theory teaching, teachers need to use conflict matrix tables to teach students. However, due to the large number of conflict matrix tables, it is not convenient for teachers to point out the principle numbers of the intersection points of two general engineering parameters, and students cannot easily determine the parameters. In the process of finding and determining the principle number of the combination of the two parameters, a lot of valuable teaching time is often spent. In addition, the existing conflict matrix table cannot hide the principle number, which is not convenient for teachers to ask students questions, and it is difficult to flexibly and efficiently for teaching
