Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional single point blood glucose meters are used, then the measurement method is simple, but the monitoring frequency is insufficient leading to undetected hyperglycemic or hypoglycemic conditions
Solution Approach 1:
The patent combines multiple functions into an integrated sensor system that includes the analyte sensor, flow control mechanism, and vascular access device. This merging enables continuous monitoring capability while managing system complexity through integration rather than separate components.
Solution Approach 2:
The patent implements continuous monitoring by maintaining constant exposure of the sensor to biological sample through the flow control mechanism that regulates fluid flow. This eliminates the间断 nature of conventional single-point measurements and provides uninterrupted glucose level data.
2Measurement precision
If continuous monitoring is implemented, then the detection accuracy and frequency are improved, but the device complexity increases
Solution Approach 1:
The patent introduces a flow control mechanism as an intermediary component that regulates the exposure of the sensor to biological sample. This mediator enables precise control of sample flow to maintain accurate continuous measurements while managing the complexity through a dedicated control element.
Solution Approach 2:
The integrated sensor system performs multiple functions including analyte detection, flow regulation, and continuous monitoring within a single system architecture. This multi-functionality approach improves measurement precision while avoiding the complexity of multiple separate devices.
3Reliability
If frequent blood sampling is performed, then the monitoring reliability is improved, but the invasiveness and inconvenience increase
Solution Approach 1:
The patent establishes continuous exposure of the sensor to biological sample through the flow control mechanism, eliminating the need for repeated invasive sampling. This continuous action maintains high detection reliability while significantly improving user convenience by avoiding frequent finger pricks or blood draws.
Solution Approach 2:
The system enables self-continuous monitoring where the sensor automatically maintains exposure to biological sample through the flow control mechanism without requiring user intervention for repeated sampling. This self-service approach improves both reliability and ease of operation by making the monitoring process automatic and non-invasive.
