Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless transmission is used to send sensor data alternately and/or non-continuously, then power consumption is optimized, but signal transmission reliability over long distances deteriorates
Solution Approach 1:
The system dynamically adjusts the transmission frequency based on alarm status. When no alarm is present, transmissions occur at optimized intervals (e.g., 30 seconds) to conserve power. When an alarm condition is detected, the system switches to continuous or near-continuous transmission mode to ensure reliable signal delivery over long distances, thus adapting transmission behavior to current operational needs
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit monitors transmission quality and sensor status. Based on this feedback, the system adjusts transmission frequency and power levels. The bidirectional communication allows the central unit to receive acknowledgment signals and adjust subsequent transmission strategies to maintain reliability while managing power consumption
2Use of energy by moving object
If wireless transmission is used with alternating intervals, then power consumption is reduced, but the ability to monitor sensor functioning status continuously deteriorates
Solution Approach 1:
The patent introduces an intermediary diagnostic system where the control unit acts as a mediator between the sensor and the monitoring system. This intermediary continuously checks sensor health status through bidirectional communication, analyzing response times and signal integrity. This allows continuous monitoring of sensor functioning without requiring continuous power-intensive transmissions from the sensor itself
Solution Approach 2:
The system maintains continuous useful action through bidirectional communication channels. While sensor transmissions may be intermittent to save power, the bidirectional nature ensures continuous monitoring capability - the control unit can随时 initiate queries to check sensor status, and the system maintains continuous readiness to detect and report alarm conditions without complete power shutdown
3Use of energy by moving object
If signal transmission intervals are extended, then power consumption is optimized, but the timeliness of alarm detection deteriorates
Solution Approach 1:
The transmission interval is made dynamic rather than static. During normal conditions, extended intervals (e.g., 30 seconds or longer) are used to optimize power consumption. However, when alarm conditions are detected or suspected, the system dynamically shortens the interval to near-real-time continuous transmission, ensuring timely alarm detection while maintaining power efficiency during stable periods
Solution Approach 2:
The sensor system performs self-service by autonomously adjusting its transmission behavior based on detected conditions. When alarm thresholds are exceeded, the sensor automatically increases transmission frequency without external intervention, ensuring timely detection while maintaining low power consumption during normal operation. The system serves its own monitoring needs through intelligent self-regulation
