Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If sensor measurements and wireless transmissions are performed according to a predetermined timing, then battery life is extended, but sensor data timeliness and precision deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of measurement and transmission intervals based on monitored conditions. The system transitions from fixed predetermined timing to adaptive variable timing, where intervals are modified in response to detected events or environmental changes, thereby maintaining data precision while managing battery consumption
Solution Approach 2:
The system changes operational parameters (measurement interval and transmission interval) based on monitored sensor data and wireless data. By adjusting these time parameters dynamically, the system optimizes the trade-off between battery life extension and data precision maintenance
2Duration of action of moving object
If sensor measurements and wireless transmissions are performed according to a predetermined timing, then battery life is extended, but sensor data timeliness deteriorates
Solution Approach 1:
The system dynamically adapts measurement and transmission timing based on actual conditions. When events occur or conditions change, the system reduces intervals to ensure timely data capture, while during stable periods it extends intervals to conserve battery, thus balancing timeliness and battery life
Solution Approach 2:
The system uses feedback from monitored sensor data and wireless data to adjust future measurement and transmission intervals. This closed-loop control ensures that data timeliness is maintained when needed while battery life is extended during normal operation
3Measurement precision
If sensor data is collected frequently to ensure data accuracy, then battery consumption increases
Solution Approach 1:
The system varies the measurement interval parameter based on monitored conditions. During periods requiring high accuracy, the interval is reduced; during stable periods, the interval is increased to reduce energy consumption, thus adapting data accuracy to actual needs
4Loss of information
If wireless transmission is performed frequently to ensure data relevance, then battery consumption increases
Solution Approach 1:
The system adjusts the transmission interval parameter dynamically based on data relevance assessments. When changes in sensor data indicate relevant events, transmission frequency increases; otherwise, transmission frequency decreases to conserve battery energy
