Solution Overview

Problem

Current glucose meters can be confusing for users when customizing glycemic ranges, leading to potential incorrect indications of blood glucose levels, as they require knowledge of editing rules and may result in overlapping ranges that misrepresent glucose measurements.

Innovation Solution

A blood glucose meter with a user interface and microprocessor that enforces guiding principles to ensure correct range settings, preventing overlapping ranges by automatically adjusting values and providing warning messages if incorrect settings are attempted, allowing users to customize ranges without needing to know specific editing rules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users are allowed to freely customize glycemic ranges, then the device becomes more adaptable to individual needs, but the device complexity and user confusion increase due to multiple editing rules

Engineering Contradiction:
Improverange customizationVSAvoidediting rules
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically adjusts range parameters (minimum and maximum values) when conflicts are detected. If the after meal minimum is lower than the before meal minimum, it is automatically raised to match the before meal minimum. Similarly, if the after meal maximum is higher than the before meal maximum, it is automatically lowered to match the before meal maximum. This automatic parameter adjustment eliminates the need for users to understand complex editing rules while maintaining adaptability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system provides immediate feedback to users when they attempt to set invalid range values. Warning messages are displayed to inform users of the conflicts between their customizations and the default ranges. This feedback mechanism guides users toward valid configurations without requiring them to memorize editing rules, thus reducing perceived complexity while preserving customization capability.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If users can customize ranges without guidance, then ease of operation improves, but measurement precision deteriorates due to overlapping ranges that misrepresent glucose measurements

Engineering Contradiction:
Improverange setupVSAvoidglucose level indication
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system enforces parameter constraints to prevent overlapping ranges. By automatically adjusting the after meal range parameters to ensure they do not exceed the before meal range boundaries, the system maintains accurate glucose level indications. This ensures that the range indicator provides reliable in-range or out-of-range feedback without requiring users to understand the constraints, thus maintaining both ease of operation and measurement precision.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system preemptively prevents invalid range configurations by detecting potential overlaps before they can misrepresent glucose measurements. When a user attempts to set an after meal minimum lower than the before meal minimum or an after meal maximum higher than the before meal maximum, the system automatically corrects these values in advance, preventing measurement misrepresentation before it occurs.

Inventive Principle:
Principle #9Preliminary anti-action

3Adaptability or versatility

If the meter provides detailed range customization options, then adaptability improves, but ease of operation worsens due to confusing editing rules

Engineering Contradiction:
Improverange configurationVSAvoiduser interface
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs self-service by automatically resolving range configuration conflicts without user intervention. When users input custom range values, the system autonomously detects conflicts with default ranges and automatically adjusts the parameters to eliminate overlaps. This self-correcting behavior allows users to freely explore customization options without needing to understand or remember editing rules, thus improving ease of operation while maintaining adaptability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system dynamically changes range parameters based on user input and default values. When conflicts are detected between custom after meal ranges and default before meal ranges, the system automatically modifies the after meal parameters to align with the before meal boundaries. This automatic parameter adjustment simplifies the user interface by removing the need for users to understand complex editing rules while preserving full customization capability.

Inventive Principle:
Principle #35Parameter changes

AI summary

Described are techniques governing the glycemic ranges that are applied and governed in the meter so the user is not required to understand or know the editing rules in order to use or set up the meter. These guiding principles will come into effect each time the user chooses to edit the ranges. There will be appropriate warning messages to inform the user if the user does not set the ranges correctly.
