Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional faulted circuit indication systems are used, then fault detection can be performed, but the systems are inadequate in withstanding harsh external elements and provide insufficient data reporting
Solution Approach 1:
The patent replaces mechanical target-based fault indication systems with electromagnetic field-based detection systems. The system uses electromagnetic sensors to detect the presence of a target (faulted circuit indicator) through electromagnetic coupling, eliminating the need for mechanical components that are susceptible to harsh environmental conditions.
Solution Approach 2:
The patent introduces an intermediary electromagnetic field as the medium for fault detection. Instead of direct mechanical or visual contact, the system uses electromagnetic coupling between the sensor and the faulted circuit indicator to detect faults, providing isolation from harsh external elements while maintaining detection capability.
2Reliability
If conventional faulted circuit indication systems are used, then fault detection can be performed, but they provide insufficient data reporting, failing to indicate connection status and simultaneously display status of multiple groups
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors and reports the status of multiple faulted circuit indicators. The electromagnetic sensor provides real-time feedback on both the presence of targets and their connection status, enabling comprehensive data reporting that includes whether indicators are properly connected to the system.
Solution Approach 2:
The patent creates a multi-functional detection system that can simultaneously detect faults across multiple groups of circuit indicators, determine connection status, and provide comprehensive data reporting. The single electromagnetic sensor system serves multiple detection purposes, eliminating the need for separate systems for different detection functions.
3Extent of automation
If radio frequency devices are used in harsh environments, then communication capability is provided, but the devices are exposed to external elements when located in proximity to faulted circuit indicators
Solution Approach 1:
The patent replaces physical RF devices located near faulted circuit indicators with electromagnetic field-based detection. The system uses electromagnetic coupling to detect faults without requiring physical proximity of electronic devices to the harsh environment where faulted indicators are located.
Solution Approach 2:
The patent uses the electromagnetic field as an intermediary that can penetrate or bridge the gap between the sensor and the faulted circuit indicator without requiring the sensor to be physically exposed to harsh environmental conditions. This allows automated fault detection while protecting the detection device from external elements.
