Solution Overview
Problem
Conventional continuous glucose monitoring systems require complex and cumbersome operations for attaching sensor modules to the body, leading to potential contamination, reduced accuracy, and inconvenient use, especially for young children and elderly adults.
Innovation Solution
A body attachable unit for continuous glucose measurement is designed with a pre-assembled sensor unit in an applicator, featuring a wireless communication chip for direct attachment to the skin without additional transmitter connections and user-controlled operation initiation, simplifying the process and enhancing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate transmitter is connected to the sensor module for glucose measurement, then telecommunication with external terminal is enabled, but device complexity and ease of operation deteriorate due to additional connection work
Solution Approach 1:
The patent combines the transmitter functionality directly into the sensor module, creating an integrated unit that eliminates the need for separate transmitter connection. The sensor module now includes both the sensing elements and the wireless communication capabilities, reducing the number of components and simplifying the attachment process while maintaining telecommunication functionality.
Solution Approach 2:
The sensor module is designed to perform multiple functions simultaneously: glucose sensing, signal processing, and wireless communication. This multi-functional integration allows the single module to replace what were previously separate components (sensor + transmitter), improving ease of operation without sacrificing communication capability.
2Manufacturing precision
If multiple operation steps are required to attach sensor module to applicator and then to body, then precise positioning is achieved, but ease of operation deteriorates due to complex and cumbersome procedures
Solution Approach 1:
The sensor module is pre-assembled and pre-positioned within the applicator during manufacturing, with precise positioning already established. This preliminary action ensures accurate placement on the body while reducing the number of steps the user must perform. The user simply needs to activate the applicator mechanism rather than manually position multiple components.
Solution Approach 2:
The sensor module is nested within the applicator in a pre-assembled configuration, where the applicator housing contains the sensor module in its correct operational position. This nested structure maintains precise positioning while simplifying the attachment process, as the entire assembly moves together as a single unit during application.
3Productivity
If the sensor module is attached before operation initiation, then measurement can begin immediately, but measurement precision deteriorates due to unstable initial status
Solution Approach 1:
The system transitions from a static pre-attachment state to an active measurement state through a controlled activation process. The applicator mechanism provides a stable initialization sequence that ensures all components are properly positioned and stabilized before measurements begin, allowing both immediate start capability and measurement precision to be maintained.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the stability and readiness of the sensor module after attachment. The operation initiation process includes verification steps that confirm proper positioning and stable status before allowing measurements to begin, ensuring both rapid deployment and measurement accuracy.

AI summary
The present disclosure relates to a continuous blood glucose measurement body attachment unit, and provides a continuous blood glucose measurement body attachment unit, which is manufactured in an assembled state in an applicator so as to minimize separate additional operations, such that the body attachment unit can be attached to the body with only a simple operation of the applicator and, particularly, the body attachment unit has a wireless communication chip so as to be capable of communicating with an external terminal, thereby enabling simple and convenient usage without an additional operation in which a separate transmitter must be connected and enabling maintenance to be more easily performed, and after the body attachment unit is attached to the body, an operation starts by the control of a user, such that an operation start time point can be adjusted to an appropriate time point according to the needs of the user, and an operation can start in a stabilized state, such that blood glucose can be more accurately measured.
