Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If leaf-spring contact charging method is used, then charging function is achieved, but wear and reduced reliability occur over time
Solution Approach 1:
The patent replaces the mechanical leaf-spring contact charging system with a wireless charging system. The wireless charging component transmits power through electromagnetic fields without physical contact, eliminating the wear and reliability issues associated with mechanical contacts. This substitution directly addresses the contradiction by maintaining charging functionality while extending service life and improving reliability.
Solution Approach 2:
The patent introduces a wireless charging component as an intermediary between the power source and the probe. This intermediary enables power transfer through electromagnetic coupling without direct physical contact, thereby avoiding the wear problems of leaf-spring contacts while maintaining effective charging.
2Reliability
If leaf-spring contact charging method is used, then charging function is achieved, but sealing performance deteriorates
Solution Approach 1:
The patent replaces the mechanical leaf-spring contact system with a wireless charging component that does not require physical contact. This eliminates the sealing gaps and potential leakage paths created by mechanical contacts, thereby improving sealing performance while maintaining charging functionality through electromagnetic fields.
3Reliability
If leaf-spring contact charging method is used, then charging function is achieved, but electrostatic interference occurs
Solution Approach 1:
The patent replaces the conductive leaf-spring contact system with a wireless charging component that transfers power through electromagnetic fields. This non-contact approach eliminates the direct conductive path that allows external static electricity to reach the PCBA, thereby preventing electrostatic interference and damage while maintaining effective charging.
