Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teaching aids for infants and children lack the ability to stimulate curiosity and interest, leading to passive learning and limited educational effectiveness due to complex structures and uncontrollable movements.
Innovation Solution
A dynamic three-dimensional teaching aid utilizing a simplified structure with magnets that apply both attractive and repulsive forces to rotate a teaching member by a predetermined angle, allowing for diverse teaching methods and storytelling through controlled movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a magnet-based operation mechanism is used to move character dolls, then the teaching aid can achieve three-dimensional movement and rotation, but the structure becomes complicated and bulky
Solution Approach 1:
The patent extracts the magnet from the character doll itself and places it only in the operation mechanism below the stage. This eliminates the need for complex internal magnet structures within each character doll, simplifying their design while maintaining full movement capability through the external operation mechanism.
Solution Approach 2:
The patent introduces a non-magnetic plate as an intermediary between the magnet in the operation mechanism and the character dolls. This plate allows the magnetic field to pass through and act on the character dolls without requiring direct contact or complex mechanical linkages, simplifying the overall structure while enabling controlled movement.
2Measurement precision
If multiple magnets are used to control rotation angle precisely, then the rotation can be adjusted more accurately, but the structure becomes more complex
Solution Approach 1:
The patent uses asymmetric placement of a single magnet within the operation mechanism rather than multiple symmetric magnets. By positioning the magnet off-center and combining it with the non-magnetic plate, the system achieves precise rotation angle control through geometric relationships rather than through multiple magnetic actuators, simplifying the structure.
3Productivity
If the character doll is designed to be moved and rotated to expose different sides, then alphabet teaching effectiveness is improved, but the operation mechanism becomes more complex
Solution Approach 1:
The patent segments the teaching aid into distinct functional components: a simple character doll body, a separate operation mechanism with magnet, and a non-magnetic plate. This segmentation allows the character doll to be designed for optimal teaching display while the movement function is handled by the external operation mechanism, improving teaching effectiveness without complicating the doll's internal structure.

AI summary
The present invention relates to a dynamic three-dimensional teaching aid that allows for alphabet teaching or storytelling for infants or children in diversified manners by dynamic movement of a teaching member with teaching content when the teaching member is moved, thereby stimulating indefinite curiosity and imagination of infants and children, meeting their learning ability, arousing interest not to be bored and to appear novel despite repeated use, and letting them actively participate in and focus on learning and that has a simplified structure, is easy to manipulate, and is accurately controllable for its movement. More specifically, the dynamic three-dimensional teaching aid is configured so that a first magnet 23 is moved under a teaching board 1 by a control rod 2, and a moving block 3 coupled with a teaching member 4 is placed, which includes an attractive force element to be attracted by the first magnet 23 and a second magnet 32, on a side of the attractive force element, to exert a repulsive force to the first magnet 23 to be rotated depending on changes in the moving direction.
