Biometric Alarm System with Dynamic Form Switching for Hypoglycemia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood sugar monitoring systems, particularly those using intermittent finger prick methods, struggle to accurately and continuously monitor blood sugar levels, leading to difficulties in promptly detecting hypoglycemia, which can be life-threatening.
Innovation Solution
A method for providing an alarm based on biometric data, where the alarm form is changed at predetermined intervals when a set alarm generation condition is satisfied, and the alarm is provided in an emergency form recognizable by the user irrespective of the receiver's operation mode or set alarm form, to rapidly alert the user of acute hypoglycemia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a blood gathering-type blood sugar meter is used to intermittently measure blood sugar, then the device complexity is reduced and ease of operation is improved, but the reliability of detecting hypoglycemia is worsened due to inability to continuously monitor
Solution Approach 1:
The patent introduces a receiver as an intermediary device that continuously receives biometric data from a body-attachable unit and processes alarm generation. This mediator handles the continuous monitoring task, allowing the main blood sugar meter to remain simple and easy to operate while reliability is improved through continuous data reception and intelligent alarm processing.
Solution Approach 2:
The system is divided into separate functional modules: a body-attachable unit for data collection, a receiver for continuous data reception and alarm processing, and a main blood sugar meter for periodic verification. This segmentation allows each component to be optimized independently, maintaining ease of operation for the user interface while achieving continuous monitoring for reliability.
2Reliability
If alarm form is changed at predetermined intervals to ensure continuous user recognition, then the reliability of alarm delivery is improved, but the device complexity increases due to multiple alarm form management
Solution Approach 1:
The patent implements periodic alarm delivery where the alarm form is changed at predetermined intervals during an alarm period. This periodic action ensures continuous user recognition and response while the receiver automatically manages the complexity of switching between different alarm forms (audio, vibration, display) based on elapsed time, rather than requiring complex user configuration.
Solution Approach 2:
The receiver automatically manages alarm form switching without requiring user intervention. The system self-services by tracking elapsed alarm time and autonomously selecting appropriate alarm forms from predefined patterns, reducing the complexity burden on the user while maintaining high reliability through continuous alarm delivery.
3Reliability
If emergency alarm is provided irrespective of receiver operation mode or set alarm form, then the reliability of acute hypoglycemia detection is improved, but the adaptability to user preferences is worsened
Solution Approach 1:
The patent applies different alarm delivery strategies to different alarm conditions. For general alarms, the system adapts to user preferences and receiver operation modes. For acute hypoglycemia emergencies, the system overrides preferences and delivers alarms in a standardized highly recognizable form, ensuring reliability for critical conditions while maintaining adaptability for non-critical situations.
Solution Approach 2:
The alarm delivery system dynamically adjusts its behavior based on the severity of the condition. The receiver evaluates whether an alarm represents acute hypoglycemia and automatically switches between adaptive mode (respecting user preferences) and emergency mode (standardized high-priority delivery), optimizing both reliability and adaptability across different scenarios.

AI summary
The present disclosure relates to a method for providing an alarm based on biometric data. More specifically, the present disclosure relates to a method for providing an alarm, in which when a set alarm generation condition is satisfied, in a set alarm period, an alarm form is changed at predetermined intervals, so that a user may be induced to cope with an alarm situation by continuously recognizing an alarm, and in which when a condition for an important alarm such as an acute hypoglycemia alarm occurs, the alarm is provided to the user in an emergency alarm form accurately recognizable by the user irrespective of an operation mode of a receiver or a set alarm form, so that the user may rapidly cope with acute hypoglycemia to prevent being in danger.
