Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with diabetes face challenges in monitoring and recording their blood glucose levels, as existing glucose meters do not provide a convenient way to view a history of glucose measurements, making it difficult to track changes and manage their condition effectively.
Innovation Solution
A handheld glucose meter that determines current glucose measurements and displays them on a result screen, with an option to view a logbook screen showing at least two preceding measurements, allowing users to track their glucose levels over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a handheld glucose meter displays only the current glucose measurement on the result screen, then the device complexity is minimized and the operation is simple, but the user cannot view the history of glucose measurements to track changes over time
Solution Approach 1:
The display interface is segmented into different functional screens: a result screen for current measurement and a logbook screen for historical measurements. This segmentation allows the device to provide comprehensive functionality while maintaining simple individual screen designs, resolving the contradiction between information completeness and interface complexity.
Solution Approach 2:
The patent transitions from a single-dimensional display (current measurement only) to a multi-dimensional display structure by adding a logbook screen that presents historical data in a different dimensional space. This allows users to access both current and historical measurements without complicating the primary result display.
2Adaptability or versatility
If the glucose meter stores and displays multiple previous glucose measurements in the logbook, then the user can track glucose level changes over time, but the device complexity increases due to additional memory and display requirements
Solution Approach 1:
The glucose meter is designed with multi-functionality, serving both as a simple current measurement device and as a historical data tracking system. The same device performs multiple functions (current measurement, history storage, trend analysis) without requiring separate devices, thereby achieving adaptability while managing complexity through integrated design.
Solution Approach 2:
The device automatically stores previous glucose measurements in memory as they are taken, preparing the data for future logbook viewing. This preliminary action of automatic data capture and storage eliminates the need for manual recording and simplifies the user interaction with historical data, reducing the operational complexity burden.
3Productivity
If the glucose meter provides immediate display of the current measurement result, then the measurement process is efficient and quick, but the user cannot immediately view the logbook of previous measurements without additional navigation steps
Solution Approach 1:
The system provides immediate feedback by displaying the current measurement result on the result screen, allowing the user to quickly assess their glucose level. The logbook screen is made accessible through a convenient interface element (indiciium) on the result screen, enabling users to transition to historical data viewing with minimal additional steps, thus reducing the time loss while maintaining measurement efficiency.

Data Source
AI summary
A computer-implemented method is provided for displaying glucose measurements of a person on a handheld glucose meter. The method includes: determining a current blood glucose measurement for a person from a test strip inserted into a port of the handheld glucose meter; displaying the current glucose measurement on a result screen of the handheld glucose meter immediately following the measurement of the current glucose measurement by the handheld glucose meter; providing an indicium of a logbook screen on the result screen concurrently with the display of the current glucose measurement on the result screen; and displaying the logbook screen in response to a user input received by the handheld glucose meter, where the logbook screen displays the current glucose measurement along with at least two preceding glucose measurements of the person.
