Analytical System Magazine Coding and Consumption Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient self-monitoring systems for blood sugar levels, such as those used by diabetics, face challenges in user friendliness and process reliability due to variations in test unit manufacturing batches, requiring complex code rewriting and additional instrumentation to accurately correct measured signals.
Innovation Solution
Incorporating a unique magazine identifier and a magazine-independent test counter within the measuring device, which registers and stores the consumption status of test units, allowing for simplified operation and design without the need for rewriting information on the magazine, using a microprocessor-based arithmetic unit and display for user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a code rewriting mechanism is implemented on the magazine to track test unit consumption, then consumption status can be recorded, but the magazine design becomes more complex and requires additional rewriting components
Solution Approach 1:
The consumption tracking function is extracted from the magazine and relocated to the measuring device. The magazine only contains a static identifier code, while the dynamic counting and storage functions are performed by the measuring device's microprocessor and memory, simplifying the magazine design.
Solution Approach 2:
A magazine identifier code serves as an intermediary between the magazine and the measuring device. This identifier allows the measuring device to recognize and track the specific magazine, enabling consumption monitoring without requiring complex communication or rewriting mechanisms in the magazine itself.
2Adaptability or versatility
If the code on the magazine includes all consumption information, then the magazine becomes self-sufficient, but the code structure becomes more complex and harder to read
Solution Approach 1:
The information system is segmented into two parts: a simple static identifier on the magazine and a dynamic consumption record in the measuring device. This segmentation allows the magazine to remain simple while the measuring device handles the complexity of tracking and management.
Solution Approach 2:
Instead of storing consumption information on the magazine, the system inverts the approach by storing only an identifier on the magazine and maintaining the consumption record in the measuring device. This inversion simplifies the magazine's code structure while achieving the same tracking functionality.
3Measurement precision
If a microprocessor-based test counter is implemented in the measuring device, then consumption tracking becomes more accurate, but the instrument cost increases
Solution Approach 1:
The microprocessor-based test counter automatically tracks consumption without requiring manual intervention or complex external systems. The measuring device self-manages the counting and storage functions, providing accurate tracking while keeping the system integrated and cost-effective.
