Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional smart magic cubes use numerous electronic accessories and plastic parts, then the cube can achieve smart functionality, but the weight increases and the structure becomes complex
Solution Approach 1:
The patent merges the electronic control system directly into the ball shaft structure. The PCB (printed circuit board) is integrated within the ball shaft, combining mechanical and electronic components into a single unified structure. This eliminates the need for separate electronic accessories and reduces overall structural complexity while maintaining smart functionality.
Solution Approach 2:
The ball shaft structure serves multiple functions simultaneously: it provides the mechanical rotating shaft for the magic cube, houses the electronic control system (PCB, battery, wireless module), and acts as the positioning mechanism. This multi-functionality reduces the number of separate components needed, thereby reducing complexity.
2Reliability
If conventional smart magic cubes use wire welding for assembly, then electrical connections can be made, but the wire layout becomes messy and welding costs increase
Solution Approach 1:
The patent replaces the mechanical wire welding process with a direct electrical connection system. The PCB is designed with built-in connection terminals that directly connect to the ball shaft's electrical contacts, eliminating the need for wire welding. This substitution simplifies the assembly process while maintaining reliable electrical connections.
3Measurement precision
If face position coding sensor is installed in center cover, then position sensing can be achieved, but the center cover structure becomes complex and cost increases
Solution Approach 1:
The patent combines the position sensing function with the ball shaft structure itself. The rotating shaft sensing assembly is integrated into the ball shaft, eliminating the need for a separate center cover housing. This merging simplifies the overall structure while maintaining accurate position sensing capability.
Solution Approach 2:
The patent extracts the position sensing function from the center cover and relocates it to the ball shaft structure. The sensing assembly is now part of the rotating shaft mechanism, removing the complex center cover structure while preserving the essential position sensing functionality.
4Device complexity
If conventional smart magic cubes have inaccurate position sensing, then the structure can be simpler, but the recovery speed and success rate decrease
Solution Approach 1:
The patent replaces mechanical position sensing with an electronic sensing system integrated into the ball shaft. The rotating shaft sensing assembly uses electronic sensors to detect position, providing accurate measurement while maintaining a relatively simple overall structure. This substitution enables both structural simplicity and sensing accuracy.
