Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a photoreceptor sensor and computing device are added to detect arcing events, then the safety and reliability of the utility meter is improved, but the device complexity increases
Solution Approach 1:
The photoreceptor sensor is integrated within the existing utility meter housing structure, nesting the detection component inside the meter assembly. This approach adds detection functionality while minimizing external structural changes and maintaining a compact design.
Solution Approach 2:
The computing device serves multiple functions: it processes illumination data from the photoreceptor sensor, determines arc events, generates alerts, and can trigger service disconnection. This multi-functionality consolidates detection, analysis, and response capabilities into a single integrated system.
2Measurement precision
If continuous monitoring of illumination data is performed to detect arcs, then the detection precision is improved, but the energy consumption increases
Solution Approach 1:
The computing device periodically samples illumination data from the photoreceptor sensor rather than continuously monitoring at maximum rate. This periodic sampling maintains adequate detection precision while reducing overall power consumption compared to continuous high-rate monitoring.
Solution Approach 2:
The system uses a photoreceptor sensor that is sensitive to the specific wavelength range of arc emissions, requiring less monitoring intensity and frequency to detect arcs accurately. This partial monitoring approach focuses computational resources on detecting the specific light signatures of arcs rather than general environmental monitoring.
