Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning magnets with large magnetic force are used, then positioning accuracy is improved, but start resistance increases
Solution Approach 1:
The positioning magnetic field is segmented into multiple independent magnets distributed at specific positions (corner blocks, edge blocks, and center blocks) rather than using a single large magnet. This segmentation allows the magnetic force to be distributed, providing accurate positioning while reducing the concentrated start resistance.
Solution Approach 2:
Different blocks have different magnetic configurations tailored to their specific functions: corner blocks have magnets at specific corners for positioning, edge blocks have magnets for edge positioning, and center blocks have annular magnets for rotational positioning. This local optimization ensures accurate positioning at each location while minimizing unnecessary magnetic resistance.
2Force
If springs with large elastic force are used, then rotation force is improved, but friction resistance increases
Solution Approach 1:
The patent replaces the traditional spring-based mechanical elastic force system with a magnetic force system. Magnets are embedded in blocks to provide both positioning and rotational forces, eliminating the need for physical contact between springs and blocks, thereby reducing friction resistance while maintaining rotation force.
3Stability of the object's composition
If axis is in full contact with center blocks, then structural stability is improved, but rotation resistance increases
Solution Approach 1:
The patent extracts the magnetic positioning function from the mechanical contact system. Instead of relying on full mechanical contact between the axis and center blocks, magnetic forces are used to provide positioning and rotational control, reducing mechanical friction and rotation resistance while maintaining structural stability through the magnetic field.
4Ease of manufacture
If magnets are fixed with glue, then assembly simplicity is improved, but adjustability deteriorates
Solution Approach 1:
The patent implements adjustable magnetic configurations where magnets can be repositioned or reconfigured. The magnetic blocks can be adjusted to change the magnitude and distribution of magnetic forces, allowing the system to adapt to different rotation speeds and positioning requirements. This dynamic adjustability is achieved through mechanical adjustment mechanisms rather than permanent glue fixation.
