Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If field technicians physically inspect meters to verify wiring setup, then wiring accuracy can be confirmed, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the mechanical physical inspection process with an automated electronic verification system. The IED automatically verifies its own wiring setup by analyzing electrical parameters and comparing them against expected configurations, eliminating the need for manual field technician inspection while maintaining verification accuracy.
Solution Approach 2:
The IED performs self-verification of its wiring setup by automatically monitoring electrical parameters and detecting anomalies. The device can identify its own miswiring conditions and generate alerts without requiring external inspection, enabling the system to service itself.
2Reliability
If field technicians physically inspect meters to verify wiring setup, then wiring faults can be detected, but maintenance costs increase
Solution Approach 1:
The patent replaces costly manual inspection processes with automated electronic verification embedded in the IED. This substitution eliminates the need for dispatching field technicians for routine wiring verification, significantly reducing maintenance costs while maintaining high reliability through continuous automated monitoring.
Solution Approach 2:
The IED continuously self-monitors its wiring setup and automatically detects faults, eliminating the need for external maintenance interventions for routine verification. This self-service capability reduces maintenance costs by preventing faults rather than requiring costly field repairs.
3Productivity
If remote meter reading is implemented, then operational efficiency improves, but undetected wiring errors lead to inaccurate data
Solution Approach 1:
The patent implements a feedback mechanism where the IED continuously monitors electrical parameters and compares them against expected values based on the configured wiring setup. When discrepancies are detected, the system generates alerts, providing feedback that ensures data accuracy while maintaining remote operational efficiency.
Solution Approach 2:
The patent replaces manual verification processes with automated electronic monitoring that continuously validates wiring setup correctness. This substitution enables remote reading efficiency while preventing data inaccuracies through automatic detection of wiring errors.
