Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If blood collection-typed blood glucose meter is used for intermittent measurement, then device simplicity is maintained, but measurement continuity and reliability deteriorate
Solution Approach 1:
The patent divides the blood glucose monitoring system into two functional parts: a simple blood collection-typed meter for intermittent measurement and a separate continuous monitoring system with sensor transmitter for continuous data collection. This segmentation allows each component to excel at its specific function while together providing both simplicity and continuity.
Solution Approach 2:
The patent embeds the continuous monitoring capability within the existing blood glucose management ecosystem. The sensor transmitter stores continuous measurement data locally, and when connected to the blood glucose meter, the continuous data is integrated with intermittent measurement results, nesting continuous monitoring functionality within the simpler existing device framework.
2Reliability
If continuous glucose monitoring system is implemented, then measurement precision and reliability improve, but device complexity increases
Solution Approach 1:
The patent extracts the complex continuous sensing function into a separate sensor transmitter component that can be worn independently. This extracted continuous monitoring system handles the complex data collection, while the main blood glucose meter remains simple and only needs to periodically connect for data synchronization, reducing the complexity burden on the primary device.
Solution Approach 2:
The patent creates a redundant data storage system where continuous measurement data is stored both in the sensor transmitter's memory and synchronized to the blood glucose meter's memory. This copying approach ensures data reliability and continuity even when one storage system is unavailable, without requiring a single complex centralized system.
3Reliability
If data is stored in non-volatile memory during power interruptions, then data loss is prevented, but data completeness may deteriorate due to power supply issues
Solution Approach 1:
The patent implements preliminary data validation and verification mechanisms before storing data in non-volatile memory. The sensor transmitter verifies data completeness and integrity markers before writing to memory, and the blood glucose meter performs verification when reading stored data. This preliminary action prevents corrupted or incomplete data from being stored, ensuring data completeness even during power interruptions.
Solution Approach 2:
The patent incorporates feedback mechanisms where the sensor transmitter and blood glucose meter exchange verification data and status information. When data is stored or retrieved, verification results are fed back to confirm data integrity. This feedback loop allows the system to detect and handle incomplete data transmissions or storage operations, preventing data loss despite power supply variations.
