Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional continuous glucose monitoring systems are cumbersome and inconvenient to use, requiring multiple steps for attachment and operation, which can lead to inaccurate measurements and short device lifespan, especially for users like children and elderly adults.
Innovation Solution
A body attachable unit for continuous glucose measurement is designed to be assembled in an applicator, allowing for simple attachment to the skin without additional operations, featuring a wireless communication chip for easy data transmission and a pressurizing operation module to ensure stable contact with electric contact points on a PCB, enabling precise glucose measurement initiation by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional continuous glucose monitoring systems are used, then glucose measurement function is provided, but the system is cumbersome and inconvenient to use with multiple steps for attachment and operation
Solution Approach 1:
The patent combines the sensor unit, transmitter, and applicator into an integrated assembly where the sensor unit is pre-assembled within the applicator. This merging eliminates the need for separate attachment and transmitter connection steps, reducing the number of operations required while maintaining the glucose measurement function.
Solution Approach 2:
The sensor unit is pre-assembled and prepared within the applicator before use. The applicator is designed with pre-positioned components including the sensor unit, adhesive patch, and activation mechanism, so that when the user applies the device to their body, the system is already configured and ready for immediate operation without requiring additional setup steps.
2Reliability
If conventional glucose monitoring systems require multiple operations, then comprehensive functionality is achieved, but user effort increases and contamination risk rises
Solution Approach 1:
The applicator is designed with a self-activating mechanism where the sensor unit automatically connects to the transmitter and initiates operation through the user's attachment action itself. The pressing motion required to attach the device to the body automatically triggers the electrical connection and power-on sequence, eliminating the need for separate activation steps and reducing opportunities for contamination.
Solution Approach 2:
The applicator serves as an intermediary device that facilitates the transfer of the sensor unit to the body while simultaneously managing the electrical connections and activation. The applicator's internal structure includes contact points and conductive elements that automatically establish electrical connections when the sensor unit is pressed against the body, mediating the interaction between user action and system activation.
3Adaptability or versatility
If a separate transmitter is used for data transmission, then communication functionality is provided, but the system requires additional connection steps and components
Solution Approach 1:
The transmitter is merged with the sensor unit assembly, with the transmitter integrated into the applicator structure. This combination eliminates the need for a separate standalone transmitter device, reducing the number of components that must be handled and connected while maintaining wireless telecommunication capability for data transmission to external devices.
4Ease of manufacture
If the sensor unit is not pre-assembled in the applicator, then manufacturing flexibility is maintained, but additional assembly steps are required at the point of use
Solution Approach 1:
The sensor unit is pre-assembled and pre-positioned within the applicator during the manufacturing process. The applicator is constructed with the sensor unit, adhesive patch, and electrical connections all prepared in advance, so that the only action required at the point of use is the attachment to the body, which simultaneously activates the system.

AI summary
The present invention relates to a body attachment unit for continuous blood glucose monitoring, in which a body attachment unit is manufactured so as to be assembled in an applicator, thereby minimizing additional work and allowing attachment of the body attachment unit to a body simply by operation of the applicator. In particular, a wireless communication chip is provided in the body attachment unit to enable communication with an external terminal, thereby enabling simple and convenient use without additional work of connecting a separate transmitter, and allowing easier maintenance. In addition, activation occurs by a user's operation after the body attachment unit is attached to the body, such that an activation start time can be adjusted to a time appropriate to the user's needs, and activation occurs in a stabilized state, thereby allowing more accurate blood glucose monitoring.
