Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple antennas are deployed at different locations to detect electric field strength, then the accuracy of stray voltage detection is improved, but the device complexity increases
Solution Approach 1:
The detection system is segmented into multiple antennas positioned at different locations relative to the monitored object. Each antenna independently measures electric field strength at its specific location, and the signal processing device combines these segmented measurements to determine stray voltage presence, thereby improving detection accuracy without requiring a single complex sensor
Solution Approach 2:
The system transitions from single-point detection to multi-point spatial detection by deploying antennas at different locations. This dimensional expansion from one measurement point to multiple measurement points enables the system to detect voltage gradients and determine stray voltage presence more accurately
2Reliability
If real-time monitoring and alert generation are implemented, then the safety response time is improved, but the energy consumption increases
Solution Approach 1:
The system performs periodic monitoring of electric field strength rather than continuous high-power transmission. Antennas periodically measure the electric field, and the signal processing device periodically analyzes the data to determine stray voltage conditions, enabling real-time safety monitoring with reduced energy consumption compared to continuous active transmission systems
