Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the physiological sensor operates in continuous mode, then measurement accuracy is maintained, but power consumption drastically increases
Solution Approach 1:
The patent applies dynamics by making the sensor operation mode adjustable and adaptable rather than fixed. The control unit dynamically switches between continuous and intermittent operation modes based on real-time assessment of measurement accuracy and patient condition, allowing the system to optimize the balance between measurement quality and power consumption adaptively
Solution Approach 2:
The patent changes the operational parameters of the sensor by introducing variable operation modes (continuous vs. intermittent with different cycle configurations). The control unit adjusts the duty cycle, operation time, and standby time parameters based on measured physiological data quality and patient movement detection, thereby optimizing the trade-off between measurement accuracy and energy consumption
2Use of energy by moving object
If the physiological sensor operates in intermittent mode to reduce power consumption, then power consumption is restrained, but measurement accuracy decreases due to patient movements
Solution Approach 1:
The patent implements feedback mechanisms where the control unit continuously monitors the quality of physiological measurements and detects patient movements. Based on this feedback, the system automatically adjusts the sensor operation mode - switching from intermittent to continuous mode when measurement accuracy deteriorates due to patient movement, and back to intermittent mode when conditions improve, thereby maintaining measurement quality while optimizing power consumption
3Productivity
If the sensor operation frequency is increased to monitor serious patient symptoms, then data collection frequency increases, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the sensor operation frequency based on patient condition assessment. When serious symptoms are detected through analysis of physiological parameters, the control unit increases the data collection frequency by reducing standby time or switching to continuous mode. When patient condition is stable, the system reduces frequency to optimize power consumption, creating an adaptive monitoring strategy that matches clinical needs with energy availability
