Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high power sensors are continuously activated for security monitoring, then detection capability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic sensor activation where high power sensors are switched between active and sleep states based on real-time monitoring needs. Low power sensors continuously monitor parameters and dynamically trigger high power sensors only when anomalies are detected, optimizing the balance between detection capability and power consumption.
Solution Approach 2:
The system employs periodic monitoring using low power sensors that continuously check parameters, followed by intermittent activation of high power sensors only when triggered by abnormal conditions. This periodic action pattern ensures detection capability is maintained during critical moments while minimizing overall power consumption during normal operation.
2Reliability
If high power sensors are continuously activated, then surveillance effectiveness is improved, but sensor lifespan is reduced
Solution Approach 1:
The system dynamically manages sensor operation states, switching high power sensors between active and sleep modes based on monitoring needs. This dynamic state management reduces cumulative operating hours of high power sensors, extending their lifespan while maintaining surveillance effectiveness through low power sensor monitoring and selective activation.
Solution Approach 2:
Low power sensors serve as intermediary monitoring devices that continuously assess environmental parameters without the wear and tear associated with high power sensors. They act as mediators that trigger high power sensor activation only when necessary, thereby protecting high power sensors from continuous operation and extending their operational lifespan.
3Use of energy by moving object
If low power sensors are used for continuous monitoring, then power consumption is reduced, but detection precision is limited
Solution Approach 1:
The monitoring system is segmented into two functional layers: low power sensors handle continuous routine monitoring of basic parameters, while high power sensors are reserved for detailed analysis when anomalies are detected. This segmentation allows the system to maintain low overall power consumption while ensuring high detection precision is available when needed through the high power sensor layer.
Solution Approach 2:
Low power sensors function as intermediary screening devices that filter normal conditions from abnormal conditions. They continuously monitor and only trigger high power sensors when parameters indicate potential security issues, thereby reducing the need for high precision high power sensor operation while maintaining overall detection precision for critical events.
