Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the sensor system is designed to be scalable and adapt energy consumption to circumstances, then energy efficiency is improved, but the system becomes vulnerable to external disturbances that cause unintentionally higher energy consumption
Solution Approach 1:
The patent implements a feedback mechanism by continuously measuring the actual energy consumption profile of the sensor system and comparing it against expected profiles. When deviations are detected, the system generates alerts to notify operators. This closed-loop feedback enables early detection of unintentional energy consumption increases caused by external disturbances, incorrect configurations, or unauthorized intrusions, allowing timely corrective actions to be taken.
2Measurement precision
If energy consumption monitoring is implemented continuously, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial monitoring by focusing energy consumption measurements on critical phases of the sensor system's operation rather than continuously monitoring all aspects. The system measures energy consumption during specific operational phases and compares these partial measurements against expected profiles for that phase. This approach achieves sufficient detection accuracy to identify deviations while minimizing the additional energy consumption required for monitoring.
3Use of energy by moving object
If the sensor system operates in low-power mode, then energy efficiency is improved, but the ability to detect energy consumption deviations in real-time is reduced
Solution Approach 1:
The patent implements periodic monitoring of energy consumption at strategically selected intervals during the sensor system's operation. Rather than continuous real-time monitoring, the system measures energy consumption at periodic checkpoints during critical operational phases. This periodic approach maintains energy efficiency by keeping monitoring activities minimal while still enabling timely detection of significant energy consumption deviations that indicate problems requiring attention.
