Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If magnets are adhered to the sponge body, then the toy brick can be assembled, but the magnet is easily separated and moves causing instability
Solution Approach 1:
The toy brick is divided into distinct components: a stable brick body structure and separate magnets. The magnets are positioned in specific locations (e.g., embedded in the brick body or attached to specific faces) rather than adhered to the entire sponge body, creating a more reliable assembly that maintains stability while allowing easy manufacturing.
Solution Approach 2:
The magnets are pre-positioned and fixed to the brick body before final assembly. This preliminary action ensures that the magnets are securely attached in the correct positions, preventing separation and movement during play, while still allowing for easy manufacturing through pre-assembly processes.
2Manufacturing precision
If the outward magnetisms of the magnets on the same face are the same, then the faces of the two toy bricks are aligned, but the possibility and degree of freedom of constructing models are restrained
Solution Approach 1:
Different faces of the toy brick are equipped with different magnetic configurations. For example, some faces have magnets with north polarity outward, while other faces have magnets with south polarity outward. This local differentiation allows for precise face alignment when magnets are the same, while simultaneously enabling diverse connection possibilities across different faces, thus increasing model construction freedom.
Solution Approach 2:
The toy brick employs asymmetric magnetic distribution where opposite faces or adjacent faces have different magnetic polarities. This asymmetry breaks the limitation of uniform magnetic orientation, allowing bricks to connect in multiple orientations and configurations while maintaining alignment precision through the deliberate asymmetric design.

AI summary
The present disclosure discloses a polyhedral magnetic toy brick and a combined structure. A polyhedral magnetic toy brick includes an inner-layer assembly, at least two magnets and an outer skin assembly. The inner-layer assembly includes several board bodies folded to form the inner-layer assembly. The board bodies include at least one triangular magnetic face; two magnet mounting holes are formed in the magnetic face. One magnet is mounted in each magnet mounting hole, and the two magnets on the same magnetic face have opposite outward magnetisms. The outer skin assembly wraps an outer surface of the inner-layer assembly, so that the magnets can be stably fixed on the board body and is avoided from being separated or moving relative to the board body, the board bodies with different shapes are connected, and are combined stably. Meanwhile, the possibility and diversification of constructing models are further achieved.
