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 potential contamination issues.
Innovation Solution
A sensor applicator assembly with a preinstalled sensor module and built-in battery, allowing easy attachment to the skin via a single-operated applicator, and a semi-permanent transmitter connected to the sensor module for power, with the module and applicator designed as disposables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a separate transmitter is used with the sensor module, then the transmitter can be reused semi-permanently, but the user must perform additional tasks to attach the sensor module, increasing operation complexity
Solution Approach 1:
The patent combines the sensor module and applicator into a pre-assembled unit where the sensor module is permanently attached to the applicator. This merging eliminates the need for users to separately attach the sensor module to the applicator, simplifying the operation while allowing the transmitter to be reused semi-permanently with different sensor-applicator units.
Solution Approach 2:
The sensor module is pre-installed on the applicator during manufacturing before reaching the user. This preliminary assembly action eliminates the need for users to perform attachment tasks, reducing operation complexity while maintaining the ability to reuse transmitters with multiple pre-assembled sensor-applicator units.
2Reliability
If the sensor module and applicator are made disposable, then contamination is prevented and accuracy is maintained, but waste increases and economic efficiency decreases
Solution Approach 1:
The system is segmented into disposable components (sensor module and applicator) and a reusable component (transmitter). The disposable sensor-applicator units are pre-assembled as a single unit, allowing them to be discarded together after use, while the expensive transmitter is reused semi-permanently with multiple sensor-applicator units, reducing overall waste and cost.
Solution Approach 2:
The patent applies disposable design to the sensor module and applicator, which are relatively inexpensive components that can be safely discarded after single use. This ensures contamination prevention and measurement accuracy while the more expensive transmitter is designed for semi-permanent reuse, optimizing the balance between reliability and economic efficiency.
3Ease of manufacture
If the sensor module requires separate attachment to the applicator, then the components can be manufactured independently, but the user operation becomes complex and time-consuming
Solution Approach 1:
The sensor module is pre-installed on the applicator during the manufacturing process before the product reaches the user. This preliminary assembly action eliminates the need for users to perform attachment tasks, reducing the time and complexity of user operations while still allowing the components to be manufactured using independent processes that can be optimized separately.

AI summary
The present invention 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.
