Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing continuous glucose monitoring systems require complex user operations for attaching the sensor module to the skin and involve inefficient use of disposable transmitters, leading to economic and environmental inefficiencies.
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 separate transmitter connected to the sensor module for semi-permanent use, with the module and applicator designed for disposability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate transmitter is used with each sensor module, then the sensor module can be easily replaced, but the cost and environmental waste increase due to disposable transmitters
Solution Approach 1:
The system is divided into two functional segments: a disposable sensor module for single-use glucose sensing and a reusable transmitter for continuous data processing and communication. This segmentation allows the expensive transmitter to be used multiple times while only the simpler sensor module is discarded, reducing overall waste and cost.
2Reliability
If the sensor module and applicator are made disposable, then measurement accuracy and safety are improved, but the cost and complexity of the system increase
Solution Approach 1:
The sensor module and applicator are merged into a single pre-assembled unit that is disposed of together. This integration ensures that the sensor is always attached in a controlled, sterile environment during manufacturing, eliminating the need for users to handle sterile components and reducing the risk of contamination while maintaining simple operation.
Solution Approach 2:
The sensor module is pre-attached to the applicator in a controlled manufacturing environment before use. This preliminary assembly ensures proper alignment, sterile conditions, and quality control are established before the product reaches the user, improving reliability without adding complexity to the user experience.
3Ease of operation
If the sensor module is preinstalled in the applicator, then user operation is simplified, but the manufacturing and assembly process becomes more complex
Solution Approach 1:
The sensor module is pre-installed in the applicator during the manufacturing process, creating a ready-to-use integrated unit. This preliminary assembly eliminates the need for users to perform complex attachment procedures, simplifying operation while allowing the manufacturing process to handle the assembly complexity in a controlled environment.

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.
