Blood Glucose Meter Voice Guidance Dynamic Static Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blood glucose measuring instruments for visually impaired individuals struggle to provide accurate decision-making guidance, as they rely on subjective voice outputs and require manual comparison of measurement results with past data, making it difficult for users to determine if their glucose levels are high or low compared to normal levels and necessitating immediate medical attention.
Innovation Solution
A blood glucose measuring instrument that outputs voice messages indicating whether the measured glucose level is high or low compared to a user's normal state, using both dynamic and static threshold values set by medical professionals, with dynamic values calculated based on past data and static values set securely by doctors via wireless communication, to guide users on appropriate countermeasures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice output is used to notify blood glucose levels to visually impaired subjects, then accessibility for visually impaired users is improved, but accurate decision-making capability deteriorates because users cannot accurately compare results with past data
Solution Approach 1:
The patent introduces an intermediary system (the blood glucose measuring device itself) that performs the comparison between current and past measurement results. Instead of requiring users to manually compare voice outputs, the device automatically compares current results with stored historical data and provides interpreted feedback, thus resolving the contradiction between accessibility and decision-making accuracy
Solution Approach 2:
The patent implements a feedback mechanism where the device not only outputs current blood glucose levels but also provides comparative feedback against historical data and threshold values. This feedback includes interpretations of whether results are high, low, or within normal ranges, enabling visually impaired users to make accurate decisions without manual comparison
2Loss of information
If manual comparison with past data is required, then data utilization is improved, but ease of operation deteriorates because users must rely on recollection and subjective judgment
Solution Approach 1:
The patent enables the system to serve itself by automatically performing data comparison and analysis functions. The device autonomously compares current measurement results with stored historical data, calculates deviations, and provides interpreted feedback without requiring user intervention for manual comparison, thus improving both data utilization and ease of operation
Solution Approach 2:
The patent replaces the manual mechanical process of comparing voice outputs with an automated electronic system. The device uses its processing capabilities to automatically retrieve historical data, perform comparisons, and generate interpreted feedback, substituting the manual cognitive process with an automated computational system
3Measurement precision
If threshold values are set by medical professionals via wireless communication, then decision accuracy is improved, but device complexity increases due to secure communication requirements
Solution Approach 1:
The patent makes the blood glucose measuring device multi-functional by integrating both measurement capabilities and secure communication functions into a single device. The device can operate as a standalone glucose meter while also functioning as a secure communication terminal for receiving threshold values from medical professionals, thus improving decision accuracy without significantly increasing overall system complexity
