Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional smart magic cubes use numerous electronic accessories and plastic parts, then the smart functions are achieved, but the weight becomes heavy and the structure becomes complex
Solution Approach 1:
The patent merges multiple electronic components (sensing assembly, control unit, Bluetooth module, battery) into an integrated electronic control system that is embedded within the ball shaft structure. This consolidation reduces the number of separate parts while maintaining all smart functions, directly addressing the contradiction between achieving smart capabilities and avoiding structural complexity.
Solution Approach 2:
The ball shaft structure is designed to serve multiple functions: it acts as both the mechanical rotating component and the housing for the electronic control system. The sensing assembly, control unit, and power supply are all integrated into this single universal structure, eliminating the need for separate electronic accessories and reducing overall device complexity.
2Reliability
If conventional smart magic cubes use wire welding for assembly, then electrical connections are established, but the wire layout becomes messy and quality risk increases
Solution Approach 1:
The patent replaces the mechanical wire welding process with a PCB-based electrical connection system. The sensing assembly and other components are electrically connected through standardized PCB interfaces and connecting plugs, eliminating the need for manual wire welding. This substitution improves manufacturing ease while maintaining reliable electrical connections.
3Measurement precision
If conventional smart magic cubes use face position coding sensor in center cover, then position sensing is implemented, but the structure becomes complex and cost increases
Solution Approach 1:
The patent extracts the position sensing function from the center cover structure and relocates it to the ball shaft. The sensing assembly is now part of the ball shaft rather than the center cover, simplifying the center cover structure while maintaining position sensing capability. This extraction resolves the contradiction between achieving position sensing and avoiding structural complexity.
4Adaptability or versatility
If conventional smart magic cubes are designed with many parts, then smart functions are achieved, but the cost becomes super high
Solution Approach 1:
The patent combines multiple functional components into integrated assemblies within the ball shaft, reducing the total number of parts that need to be manufactured and assembled. This merging approach maintains smart functions while lowering manufacturing costs by reducing part count and assembly complexity.
