Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If the number of puzzle pieces is increased or pattern complexity is increased, then the difficulty level is improved, but the puzzle becomes too difficult for junior players and loses adaptability for all ages
Solution Approach 1:
The puzzle is segmented into modular units (rhombic dodecahedron shapes) that can be arranged in multiple configurations. Each unit has standardized connection surfaces that allow flexible assembly, enabling the same set of pieces to form different difficulty levels through varying arrangement complexity rather than increasing piece count
Solution Approach 2:
The puzzle pieces are designed with universal connection interfaces that work across all puzzle configurations. The same physical pieces can be used for simple arrangements suitable for junior players or complex arrangements for advanced players, making the puzzle adaptable to all ages without requiring different piece sets
2Ease of operation
If conventional joining methods with patterns are used, then the puzzle provides clear guidance for assembly, but the joining method becomes monotonous and lacks variety in solutions
Solution Approach 1:
The rhombic dodecahedron units feature asymmetric connection surfaces with distinct convex and concave interfaces. This asymmetry provides clear guidance for proper assembly orientation while simultaneously enabling multiple valid configuration patterns, as different sequences and arrangements of the same asymmetric units can all result in correct final structures
Solution Approach 2:
The puzzle allows dynamic reconfiguration where pieces can be assembled in multiple valid sequences and arrangements. Rather than a single fixed pattern, the system supports multiple solution paths and final configurations, maintaining ease of operation through standardized interfaces while providing variety in joining methods
3Ease of manufacture
If the puzzle uses simple geometric shapes like squares or spheres, then the manufacturing is easier, but the spatial rotation and mental rotation training effect is reduced
Solution Approach 1:
The puzzle uses rhombic dodecahedron shapes with curved facial surfaces instead of simple flat-sided polyhedra. This curvature provides visual and tactile cues that enhance spatial rotation training while maintaining manufacturability through standard molding processes. The curved surfaces on each face help players visualize and manipulate the three-dimensional orientation of pieces more effectively than flat surfaces

AI summary
A multiple rhombic dodecahedron puzzle includes a plurality of wooden puzzles arranged in a multiple rhombic dodecahedron. The multiple rhombic dodecahedron is equivalent to a cube formed by a plurality of rhombic dodecahedrons connecting to each other. Each of the wooden puzzles includes two unit elements. The two unit elements are connected to each other and are the same others. Each of the two unit elements has a plurality of surfaces. Each of the surfaces has a diamond shape or a triangular shape. Two of the surfaces which in the triangular shape are connected to each other in order to form a concave shape.
