Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous glucose monitoring systems (CGMSs) require manual user intervention for power supply and pairing with user terminals, which can be cumbersome, especially for senior citizens or individuals unfamiliar with the pairing process, and may lead to missed glucose measurements due to battery power limitations.
Innovation Solution
An apparatus that uses a near field communication (NFC) module to supply power to a CGMS when within a certain distance of a user terminal, and automatically performs pairing through both NFC and Bluetooth communication modules, ensuring continuous operation even when the user terminal is out of NFC range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual user intervention is required for power supply and pairing, then user control is maintained, but ease of operation deteriorates and user burden increases
Solution Approach 1:
The CGMS performs self-powering through NFC communication with the user terminal, automatically obtaining power supply information without user intervention. The system also performs self-pairing by automatically establishing Bluetooth connection using the connection information obtained through NFC, eliminating the need for manual pairing operations.
Solution Approach 2:
The NFC module first obtains power supply information and connection information from the user terminal before the actual power supply and data transmission occur. This preliminary acquisition of information enables the subsequent automatic power supply and pairing processes to proceed without user intervention.
2Ease of operation
If automatic pairing is implemented, then ease of operation improves, but reliability may deteriorate due to potential connection failures
Solution Approach 1:
The system continuously monitors the Bluetooth connection status between CGMS and user terminal. When connection failure is detected, the system automatically performs re-pairing operations to restore connectivity, ensuring reliable continuous glucose monitoring without user intervention.
3Productivity
If continuous operation is ensured, then productivity improves, but use of energy deteriorates due to extended battery consumption
Solution Approach 1:
The CGMS operates in periodic cycles, performing glucose sensing and data transmission only when triggered by power supply information from the user terminal via NFC. This periodic operation pattern allows the system to remain in low-power state between measurements, extending battery life while ensuring continuous monitoring capability.

AI summary
An apparatus for controlling operations of a continuous glucose monitoring system. When a continuous glucose monitoring system is located within a certain distance from a user terminal, power of a battery is supplied to the continuous glucose monitoring system through a power switch switched on by an enable signal generated by a near field communication module, thereby operating the continuous glucose monitoring system without user intervention. The near field communication module provides connection information to the user terminal, thereby automatically performing a pairing connection with the user terminal using the near field communication module and a bluetooth communication module. When the pairing connection with the user terminal is completed, an enable signal generated by the bluetooth communication module is provided to the power switch, thereby maintaining the pairing connection with the user terminal even when the user terminal is outside of range for near field communication.
