Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the analyte sensor and sensor electronics are connected after implantation, then the system can be deployed flexibly, but user interaction is required and connection reliability may be compromised
Solution Approach 1:
The analyte sensor and sensor electronics are pre-connected in a pre-assembled unit before implantation, eliminating the need for user connection actions and ensuring reliable electrical contact from the start of operation
2Productivity
If the sensor electronics are activated immediately upon connection, then data collection can begin promptly, but false activations may occur due to noise
Solution Approach 1:
The system monitors electrical signals from the analyte sensor and uses feedback mechanisms to verify that activation conditions are truly met, distinguishing genuine insertion events from noise-induced false signals
Solution Approach 2:
The system performs preliminary verification of activation conditions by monitoring electrical signals before actually activating data collection, ensuring that activation occurs only when proper sensor insertion is confirmed
3Measurement precision
If the sensor remains in active state continuously, then real-time monitoring is maintained, but power consumption increases
Solution Approach 1:
The sensor electronics alternate between active measurement states and low-power sleep states, performing periodic measurements and remaining in low-power mode between measurements to conserve energy while maintaining monitoring capability
