Description

Technical Field

[0001] The present invention relates to the technical field of teaching equipment, in particular to a conflict matrix teaching device based on TRIZ theory. Background Art

[0002] The conflict matrix, also known as the contradiction matrix, is a 39x39 contradiction matrix created by Altshuller, who organically linked 39 common engineering parameters with 40 inventive principles, establishing corresponding relationships. The matrix is ​​the result of Altshuller's research on 2.5 million patents. The matrix is ​​highly coherent and self-contained. Users can directly identify the inventive principles that resolve the conflict based on two conflicting common engineering parameters in the system and apply these principles to solve the problem.

[0003] The first row of the contradiction matrix contains the codes for 39 common engineering parameters, and the second row contains the names of the 39 common engineering parameters. Vertical rows represent parameters to be improved, while horizontal rows represent parameters that could deteriorate. The 39×39 engineering parameters form a matrix with 1,521 squares, spanning both row and column dimensions. Within 1,263 of these squares are numbers, representing the codes for the inventive principles recommended by TRIZ to resolve the corresponding technical contradictions.

[0004] Studying, researching, and applying TRIZ theory can significantly shorten the invention process and enhance product innovation. After more than half a century of development, and particularly in the 21st century, TRIZ theory has become a mature theoretical and methodological system for solving practical problems in new product development. The TRIZ Contradiction Matrix has become an inventive tool for directly resolving contradictions and solving problems.

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

The principle serial number is printed on one end face of the display board 9, and the other end face of the display board 9 is fixedly connected to the rotating shaft 8. One end of the rotating shaft 8 is movably inserted in the fixed sleeve 5 and a spur gear 10 is installed on the other end. The spur gear 10 is meshed with the rack 11, and the electromagnet 13 drives the bar magnet 12 to move unidirectionally in the slide guide rail 14. The end of the bar magnet 12 facing away from the electromagnet 13 is connected to the inner wall of the parameter cell 4 through a horizontally arranged spring 15; a transparent window 16 corresponding to the display board 9 is provided on the bar shell 1. In the natural state, the end face of the display board 9 printed with the principle serial number faces the transparent window 16, and the transparent window 16 is made of transparent organic glass to reduce reflection.

[0033] A first lamp holder 17 and a first normally-open touch switch 18 are mounted on the cell 4 corresponding to the general engineering parameters in the improved characteristic column. A first laser emitter 19 is mounted on the first lamp holder 17. A second lamp holder 20 and a second normally-open touch switch 21 are mounted on the cell 4 corresponding to the general engineering parameters in the deteriorated characteristic column. A second laser emitter 22 is mounted on the second lamp holder 20. The first laser emitter 19 and the second laser emitter 22 are arranged perpendicularly.

[0034] The cell 4 corresponding to the principle number grid is provided with a normally closed touch switch 23;

[0035] The cable 2 is electrically connected to the electromagnet 13, the first laser emitter 19, the first normally-open touch switch 18, the second laser emitter 22, the second normally-open touch switch 21, and the normally-closed touch switch 23 to form a control circuit. The electromagnet 13 and its corresponding normally-closed touch switch 23 are connected in series and then in parallel in the circuit.

The second laser emitter 22 and its corresponding second normally-open touch switch 21 are connected in series and then in parallel in the circuit. A third normally-open touch switch 24 is connected in series in the circuit for controlling the power supply to the electromagnet 13 and the normally-closed touch switch 23.

[0036] The first laser emitter 19 and the second laser emitter 22 are both inline laser positioning lights, which emit inline-shaped light to facilitate observation of the intersection of the light rays;

[0037] The hanging ears 25 are respectively fixed to the top of the strip-shaped housing 1 on two opposite sides of the bamboo slip mechanism 3;

[0038] The cells 4 of the strip-shaped housing 1 are provided with openings 26 for wiring. The cables 2 are connected to the top and bottom ends of each strip-shaped housing 1 through the openings 26 to form a bamboo mechanism 3. The cells 4 at the top and bottom ends of each strip-shaped housing 1 have three openings 26, while the remaining cells 4 have two openings 26, thereby facilitating the wiring of the cables 2. The cables 2 are provided with a limiting ring 27 for limiting the movement of the strip-shaped housing 1 on the cables 2. The limiting ring 27 is made of rubber and is fixedly sleeved on the cables 2.

[0039] A fixed column 28 is fixed to the bottom of the parameter cell 4, and the slide rail 14 is fixed on the fixed column 28;

[0040] The rotating shaft 8, the display board 9, the spur gear 10, the rack 11, the fixing column 28 and the slide rail 14 are all made of non-magnetic materials and will not be attracted by the electromagnet 13 and the bar magnet 12, and will not affect the flipping of the display board 9;

[0041] Common engineering parameter names are printed on the first normally-open touch switch 18 and the second normally-open touch switch 21 .

[0042] The working principle of this embodiment is as follows: the cable 2 passes through the strip housing 1, and the strip housing 1 is limited to the cable 2 by the limiting ring 27, so that the length of the cable 2 between each strip housing 1 is consistent, forming a bamboo-like structure, which can be easily rolled up and is flexible and convenient to use. It takes up little space when rolled up and can be unfolded when in use. It is convenient to lift it through the lifting lug 25. In the natural state, the end face of the display board 9 printed with the principle serial number faces the transparent window 16, and the principle serial number is normally displayed, which is suitable for teaching;

[0043] During teaching, the power plug is inserted into the mains interface, and the teacher only needs to press the first normally open touch switch 18 and the second normally open touch switch 21 corresponding to the universal engineering parameters to make the first laser emitter 19 and the second laser emitter 22 emit lasers. The intersection of the two lasers is the principle serial number of the intersection of the two universal engineering parameters, which allows students to directly observe the principle serial number at the grid, saving valuable teaching time, facilitating students' learning and improving teaching efficiency. For example, when the teacher is teaching how to solve the contradiction between the deterioration of the "weight of the moving object" and the "length of the moving object", it is necessary to find the combination point of the two parameters. The combination point is the principle serial number recommended for solving the contradiction. The teacher can press the improvement characteristic column by hand or with a pointer. The first normally open touch switch 18 of sequence number 1 is pressed, and then the second normally open touch switch 21 of deterioration characteristic sequence number 3 is pressed. The first normally open touch switch 18 is closed to energize the first laser emitter 19, and the second normally open touch switch 21 is closed to energize the second laser emitter 22. The first laser emitter 19 and the second laser emitter 22 are both inline laser positioning lights. The first laser emitter 19 and the second laser emitter 22 emit inline lasers. The two vertical lasers intersect on the cell 4 of the recommended principle sequence number. The principle sequence number on the display board 9 can be directly seen through the transparent window 16. Pressing the first normally open touch switch 18 and the second normally open touch switch 21 again can turn off the first laser emitter 19 and the second laser emitter 22.

[0044] When the teacher asks a question, he presses the third normally open touch switch 24, and all the electromagnets 13 are energized. After the electromagnet 13 is energized, the end facing the bar magnet 12 is the N pole, and the end of the bar magnet 12 facing the electromagnet 13 is also the N pole. Therefore, the electromagnet 13 will repel the bar magnet 12, and the bar magnet 12 slides away from the electromagnet 13 in the slide rail 14. The spring 15 is compressed, and the rack 11 and the bar magnet 12 are fixed with AB glue. The rack 11 moves with the bar magnet 12, and the rack 11 drives the gear to rotate during the movement. The gear rotates at least 90 degrees, and the gear drives the display board 9 through the shaft 8. Rotate, one end of the shaft 8 rotates in the sleeve, the shaft 8 is connected to the inner ring of the bearing 7, the shaft 8 is kept in a fixed position and rotates by the bearing 7, the shaft 8 is fixed to the display board 9 by AB glue, after the display board 9 is flipped 90 degrees, the principle serial number on the display board 9 cannot be observed through the transparent window 16, which is convenient for students to answer, press the corresponding normally closed touch switch 23, the corresponding electromagnet 13 is powered off, and the spring 15 restores and drives the display board 9 to reset, the shaft 8, display board 9, spur gear 10, fixed column 28, rack 11 and slide guide rail 14 are made of PE material and will not be adsorbed by the electromagnet 13 and the bar magnet 12.
