Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate electric field probe and magnetic field probe are used for scanning, then measurement accuracy is maintained, but measurement time increases due to frequent probe replacement and calibration
Solution Approach 1:
The patent combines separate electric field probe and magnetic field probe into a single integrated probe assembly. This allows both probes to be positioned and scanned simultaneously at predetermined locations, eliminating the need for frequent probe replacement and calibration while maintaining measurement accuracy through the integrated design.
Solution Approach 2:
The integrated probe is divided into distinct electric field detecting portion and magnetic field detecting portion with predetermined spacing. This segmentation allows each probe type to function independently with its own detection capabilities while being part of a unified scanning system, enabling simultaneous operation without interference.
2Reliability
If multiple probes are used for comprehensive field detection, then measurement completeness is improved, but device complexity increases
Solution Approach 1:
Multiple probes (electric field and magnetic field) are merged into a single integrated probe assembly with a unified support structure and scanning mechanism. This reduces the number of separate devices needed while maintaining comprehensive detection capabilities through the coordinated arrangement of multiple sensing elements.
