Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex coupling mechanisms are used to ensure reliable electrical contact and mechanical stability, then data readout reliability is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent replaces complex mechanical coupling mechanisms with a magnetic field-based coupling system. Magnets embedded in both the transmission part and data readout part create magnetic attraction forces that ensure reliable electrical contact between contact surfaces without requiring complex mechanical fastening structures. This substitution of mechanical systems with magnetic fields directly resolves the contradiction by maintaining data readout reliability while significantly reducing coupling mechanism complexity.
Solution Approach 2:
The patent utilizes magnetic field strength as a controllable parameter to achieve reliable coupling. By adjusting the strength and positioning of magnets, the system ensures sufficient magnetic attraction force to maintain stable electrical contact between the transmission part and data readout part. This parameter-based approach allows for reliable data readout without complex mechanical structures, effectively resolving the contradiction between reliability and device complexity.
2Reliability
If complex coupling mechanisms are used to ensure secure electrical contact, then data transmission accuracy is improved, but manufacturing costs increase
Solution Approach 1:
The patent replaces expensive and complex mechanical coupling mechanisms with a magnetic field-based system that is simpler and cheaper to manufacture. The magnetic coupling ensures secure electrical contact for accurate data transmission without requiring precision-machined mechanical fasteners or complex alignment mechanisms, thereby reducing manufacturing costs while maintaining data transmission accuracy.
Solution Approach 2:
The magnetic coupling system is self-aligning and self-adjusting, automatically ensuring proper contact between electrical contacts without requiring complex external alignment mechanisms or precision manufacturing. The magnetic attraction force naturally pulls the components into proper alignment, eliminating the need for expensive precision machining and assembly processes while ensuring accurate data transmission.
3Reliability
If complex coupling mechanisms are used to ensure mechanical stability, then coupling reliability is improved, but coupling time increases
Solution Approach 1:
The patent replaces time-consuming mechanical fastening operations with instantaneous magnetic attraction. When the data readout part is brought near the transmission part, the magnets automatically create strong attractive forces that secure the coupling immediately without requiring manual fastening, alignment adjustments, or complex mechanical engagement procedures. This magnetic substitution dramatically reduces coupling time while maintaining coupling reliability.
Solution Approach 2:
The magnets are pre-positioned and pre-configured within the components during manufacturing, so that when the components are brought together during use, the magnetic coupling activates immediately without requiring any additional setup or adjustment steps. This preliminary configuration eliminates time-consuming assembly operations while ensuring reliable mechanical stability during data transmission.
