Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the capacity of the current supply portion is increased to supply sufficient power to operate the sensor device, then the power supply capability is improved, but the physical size such as weight and volume of the current supply portion increases
Solution Approach 1:
The patent replaces the conventional AC power supply system with a DC power supply system combined with a magnetic field generation system. Instead of using a large-capacity AC current supply portion that requires high physical capacity, the invention uses a DC power source (such as a rechargeable battery) that converts electrical energy to magnetic energy through a coil, which then induces current in the sensor device's coil. This substitution of the power transmission mechanism dramatically reduces the size and weight of the power supply portion while maintaining sufficient power delivery capability.

Solution Approach 2:
The sensor device is designed to generate its own operating power through electromagnetic induction. When placed near the test device, the magnetic field generated by the coil induces current in the sensor device's coil, which powers the sensor device's operations. This self-powering mechanism eliminates the need for external power connections and heavy power supply equipment, significantly improving portability while maintaining full operational capability.
