Integrated Glucose Sensor Applicator for Timed Measurement Start
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional continuous glucose monitoring systems require complex and cumbersome operations for attaching the sensor module to the body, leading to potential inaccuracies and inconvenience, especially for users like young children or elderly adults, and lack the ability to initiate measurements at a user-defined time.
Innovation Solution
A continuous blood glucose measurement apparatus is designed with a body attachable unit pre-assembled in an applicator, allowing simple attachment to the body with minimal user effort, featuring a wireless communication chip for convenient connectivity and user-controlled operation initiation, and includes a needle extraction mechanism to facilitate easy insertion and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor module is attached separately using a complex applicator operation, then the measurement function is achieved, but the ease of operation deteriorates and contamination risk increases
Solution Approach 1:
The patent combines the sensor module and applicator into a single integrated unit where the sensor module is pre-assembled within the applicator housing. This merging eliminates the need for separate attachment operations and reduces the number of manual steps required, directly improving ease of operation while maintaining measurement functionality.
Solution Approach 2:
The sensor module is pre-assembled and prepared within the applicator before actual use. The applicator is designed with pre-positioned components and pre-configured sensor elements, allowing the user to simply activate the attachment mechanism without performing complex assembly or alignment operations during the measurement process.
2Ease of operation
If the body attachable unit is pre-assembled in the applicator, then the ease of operation improves, but the manufacturing complexity increases
Solution Approach 1:
The integrated unit is designed with modular segments that can be manufactured separately and then assembled. The applicator housing, sensor module, and internal components are divided into distinct manufacturable segments, allowing each to be produced using optimized processes and then combined through standardized interfaces, thereby reducing overall manufacturing complexity.
Solution Approach 2:
The applicator is designed with universal features that serve multiple functions: it acts as both the delivery mechanism for the sensor module and the final housing for the attached device. This multi-functionality reduces the number of separate components needed and simplifies the manufacturing process by consolidating functions into a single integrated structure.
3Measurement precision
If the needle is extracted after sensor insertion, then the measurement accuracy improves, but the loss of time increases
Solution Approach 1:
The needle extraction mechanism is pre-configured and automatically activated as part of the attachment sequence. The system is designed to extract the needle immediately after sensor insertion is complete, eliminating the need for separate manual extraction steps and reducing the time loss associated with maintaining the needle in place during measurement.
Solution Approach 2:
The attachment process is designed as a continuous sequence where sensor insertion and needle extraction occur in immediate succession without interruption. The mechanism maintains the sensor in the body while automatically managing the needle removal, ensuring continuous measurement capability without time loss from separate operations.

AI summary
The present disclosure relates to a continuous blood sugar measuring device, and provides a continuous blood sugar measuring device which is capable of minimizing additional work of a user in order to attach a body attachment unit, by manufacturing the body attachment unit to be assembled inside an applicator so that the body attachment unit can be attached to the body simply by operating the applicator and, particularly: communicating with an external terminal by providing a wireless communication chip in the body attachment unit so that simple and convenient use is possible and maintenance can easily be performed without the additional work of connecting a separate transmitter; initiating operation by a manipulation of the user, after attaching the body attachment unit to the body, so that an operation initiation time can be adjusted to a suitable time according to the need of the user; and initiating operation in a stabilized state to enable a more accurate measurement of blood sugar.
