Solution Overview

Problem

Conventional continuous glucose monitoring systems face issues with temporary communication disconnections between sensor transmitters and communication terminals, leading to unreceived biometric information, which necessitate energy-intensive and computationally burdensome retransmissions to ensure data continuity.

Innovation Solution

A method that determines unreceived biometric information only during non-receipt communication cycles, using biometric information identifiers to selectively receive necessary data upon user request, reducing computational load and energy waste by minimizing regular checks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If biometric information is transmitted continuously to ensure real-time monitoring, then monitoring reliability is improved, but power consumption increases and battery life decreases

Engineering Contradiction:
Improvemonitoring reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic transmission of biometric information instead of continuous transmission. The sensor controller transmits data at predetermined time intervals, and the receiver processes data periodically. This reduces power consumption while maintaining adequate monitoring reliability through regular updates.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The transmission frequency is made dynamic and adaptive. The system adjusts the transmission interval based on glucose level conditions - transmitting more frequently when glucose levels are abnormal or changing rapidly, and less frequently when stable. This dynamic adjustment optimizes both reliability and power consumption.

Inventive Principle:
Principle #15Dynamics

2Speed

If biometric information is transmitted at frequent intervals to improve response time, then response speed is improved, but power consumption increases

Engineering Contradiction:
Improveresponse speedVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The system uses periodic transmission with variable intervals rather than constant frequent transmission. Data is transmitted at intervals that adapt to the current glucose state, providing rapid response when needed while conserving energy during stable periods.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The transmission interval parameter is dynamically changed based on glucose level conditions. When glucose levels indicate urgency (hyperglycemia or hypoglycemia), the interval decreases for faster response. When stable, the interval increases to reduce power consumption.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If continuous transmission of biometric data is implemented to ensure data completeness, then information accuracy is improved, but communication resource usage increases

Engineering Contradiction:
Improvedata completenessVSAvoidcommunication resource usage
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Periodic transmission at optimized intervals maintains adequate data completeness for monitoring purposes while reducing communication resource usage compared to continuous transmission.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system transmits data at intervals that are sufficient for monitoring reliability rather than continuously. This partial action approach provides adequate information for health monitoring while conserving communication resources.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The present disclosure relates to a method for transmitting or receiving biometric information between a sensor transmitter and a communication terminal in a continuous blood glucose measurement system and, more specifically, to a method for transmitting or receiving biometric information, wherein: it is not determined at every regular communication period whether biometric information has been successfully transmitted or received between a sensor transmitter and a communication terminal; it is determined whether unreceived biometric information exists only at a unreceived communication period relatively larger than the regular communication period; if unreceived biometric information exists, the unreceived biometric information is received; and it is accordingly possible to reduce computing loads required to determine at every regular communication period whether unreceived biometric information exists, and the waste of energy required to receive unreceived biometric information at every regular communication period.
