Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous glucose monitoring systems require complex user operations for attaching sensor modules, and separate transmitters are often disposable, leading to inefficiency and environmental waste.
Innovation Solution
A sensor applicator assembly with a preinstalled sensor module and built-in battery, allowing for simple attachment to the skin using an applicator, and a semi-permanent transmitter connected to the sensor module for power, with the module and applicator designed for disposability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor module and applicator are provided as separate components requiring user assembly, then the system allows flexibility in usage, but the user operation becomes complex and time-consuming
Solution Approach 1:
The patent combines the sensor module and applicator into a single integrated assembly where the sensor module is pre-installed within the applicator. This merging eliminates the need for users to manually assemble separate components, thereby simplifying the attachment process to a single-step operation while maintaining system functionality.
Solution Approach 2:
The sensor module is pre-installed in the applicator during manufacturing before reaching the user. This preliminary action of assembly is performed in advance, so that when the user receives the device, the complex assembly task has already been completed, and only the simple attachment to the skin remains.
2Reliability
If the transmitter is designed as disposable along with the sensor module, then the system ensures accuracy and safety through single-use components, but it increases waste and reduces economic efficiency
Solution Approach 1:
The system is segmented into disposable and reusable components. The sensor module and applicator are designed as disposable units that ensure accuracy through single-use, while the transmitter is designed as a reusable component that can be paired with multiple sensor modules, thereby reducing waste while maintaining measurement reliability.
Solution Approach 2:
The disposable sensor module and applicator are discarded after single use to ensure accuracy and safety, while the transmitter is recovered and reused with subsequent sensor modules. This selective discarding and recovery approach minimizes material waste while maintaining the reliability benefits of single-use critical components.
3Productivity
If multiple user tasks are required for attaching the sensor module, then the system allows for precise control of the attachment process, but it increases the time and complexity of user operation
Solution Approach 1:
Multiple functions (sensor module housing, attachment mechanism, and sensor containment) are merged into the integrated assembly, allowing the user to perform a single attachment action that simultaneously completes multiple tasks that would otherwise require separate steps.

AI summary
The present it relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.
