Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If leaf-spring contact charging method is used, then charging function is achieved, but structural wear and reduced reliability occur
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 spring contacts that degrade over time with repeated engagement and disengagement.
Solution Approach 2:
The patent introduces a wireless charging component as an intermediary between the power source and the probe. This intermediary uses electromagnetic fields to transfer energy without requiring direct mechanical contact, thereby avoiding the wear problems of leaf springs while maintaining the charging function.
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 can be hermetically sealed. The wireless charging component includes a coil and circuitry that can be enclosed in a sealed housing, preventing ingress of moisture and contaminants while maintaining charging functionality through electromagnetic coupling.
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 system that uses electromagnetic fields for power transfer. This eliminates the conductive path that allows static electricity to enter the probe's electronics, thereby preventing electrostatic discharge damage and interference.
Solution Approach 2:
The wireless charging component acts as an intermediary that transfers energy through electromagnetic fields without creating a conductive connection. This intermediary approach blocks the path for electrostatic interference while maintaining the essential charging function.
4Reliability
If wireless near-field charging is used, then charging stability is improved, but device complexity increases
Solution Approach 1:
The patent integrates the wireless charging component into the existing probe structure, combining the charging coil and circuitry with the probe's housing and electrical components. This merging approach reduces overall system complexity by eliminating separate mechanical contact components and simplifying the charging interface.
