Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If magnetism is used for coupling, then coupling force is improved, but space utilization deteriorates due to space needed for magnetic components
Solution Approach 1:
The patent replaces magnetic coupling with a mechanical coupling system consisting of a coupling protrusion and coupling groove. This mechanical structure achieves reliable coupling without requiring additional space for magnetic components, thereby improving space utilization while maintaining coupling force.
2Force
If magnetism is used for coupling, then coupling force is improved, but design freedom deteriorates due to interference with sensors
Solution Approach 1:
The patent substitutes magnetic coupling with a purely mechanical coupling mechanism (protrusion and groove structure) that does not generate magnetic fields. This eliminates interference with internal sensors while maintaining coupling functionality, thereby preserving design freedom and sensor placement flexibility.
3Device complexity
If simple hook structure is used, then device complexity is reduced, but durability deteriorates due to easy wear out
Solution Approach 1:
The coupling device is segmented into distinct functional elements: a coupling protrusion for insertion, a coupling groove for reception, and an elastic bar for providing coupling force. This segmentation allows each component to be optimized for its specific function, improving overall durability while maintaining reasonable structural complexity.
Solution Approach 2:
The coupling system incorporates an elastic bar that provides dynamic coupling force. The elasticity allows the coupling mechanism to absorb stresses and deformations during separation and coupling operations, significantly improving durability compared to rigid hook structures.
4Device complexity
If simple hook structure is used, then device complexity is reduced, but ease of operation deteriorates due to difficult separation and coupling
Solution Approach 1:
The elastic bar in the coupling device provides dynamic compliance that facilitates smooth operation. During coupling, the elastic bar deforms to accommodate the insertion of the protrusion; during separation, it maintains sufficient holding force. This dynamic behavior makes the coupling and separation operations smooth and user-friendly.
