Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional contact-based power supply method is used, then the device structure is simple, but the power supply stability deteriorates due to poor contact and wear
Solution Approach 1:
The patent replaces the mechanical contact-based power supply system with a magnetic coupling resonance-based wireless power transmission system. The transmitter coil and receiver coil establish electromagnetic coupling without physical contact, eliminating wear and contact instability while maintaining power supply functionality. This substitution directly resolves the contradiction by improving reliability through non-contact power transfer.
Solution Approach 2:
The patent introduces magnetic coupling resonance as an intermediary mechanism between the power source and the display module. The magnetic field acts as a mediator to transfer energy from the transmitter coil to the receiver coil without direct electrical contact, thereby maintaining power supply stability while avoiding the wear and contact issues of traditional methods.
2Ease of repair
If traditional contact-based power supply method is used, then the device structure is simple, but the maintenance cost increases due to wear
Solution Approach 1:
By replacing the mechanical contact system with a magnetic coupling resonance system, the patent eliminates the wear that occurs in contact-based power supply. The non-contact nature of electromagnetic coupling means there are no sliding contacts or brushes to wear out, significantly reducing maintenance requirements and costs while accepting increased structural complexity.
3Reliability
If magnetic coupling resonance power supply is implemented, then the power supply stability is improved, but the device complexity increases
Solution Approach 1:
The patent accepts increased device complexity as the trade-off for achieving superior power supply stability through magnetic coupling resonance. The wireless power transmission system with transmitter and receiver coils provides stable, wear-free power delivery, justifying the additional structural complexity by eliminating contact-based reliability issues.
