Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a continuous glucose monitoring system is used to continuously measure blood glucose levels, then the ability to detect hypoglycemia and manage diabetes effectively is improved, but the risk of data loss due to power supply problems during storage becomes a concern
Solution Approach 1:
The patent applies local quality by creating different storage areas with different characteristics within the memory. Specifically, it divides the memory into a first storage area for normal data storage and a second storage area for backup data storage. This local differentiation ensures that even if one area experiences power supply problems, the other area remains intact, thus resolving the contradiction between continuous monitoring reliability and data loss risk.
Solution Approach 2:
The patent implements beforehand cushioning by pre-establishing a backup storage area before any data loss can occur. The control unit is configured to store blood glucose measurement data in both a first storage area and a second storage area simultaneously or sequentially. This preparatory backup mechanism ensures that if power supply problems occur during storage in the first area, the data is already protected in the second area, thus preventing data loss while maintaining continuous monitoring capability.
2Device complexity
If blood collection-typed blood glucose meter is used for intermittent measurement, then the device complexity is reduced, but the ability to accurately grasp frequently changing blood glucose levels deteriorates
Solution Approach 1:
The patent replaces the mechanical blood collection method with a continuous glucose monitoring system that uses a sensor transmitter inserted into the body. This transmitter continuously measures blood glucose levels through body fluid extraction without requiring repeated finger pricks. The measurement data is then converted to digital format and stored in memory, providing accurate, continuous monitoring while maintaining relatively simple device operation for the user.
3Reliability
If multiple storage areas are used for data redundancy, then the completeness of blood glucose measurement data is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the memory into distinct storage areas - specifically a first storage area and a second storage area. Each area serves a specific function: the first area for primary data storage and the second area for backup storage. This segmentation provides data redundancy and protection against data loss while maintaining a relatively simple overall structure. The control unit manages these segmented areas through straightforward operations of storing and comparing data between the two areas.
