Solution Overview

Problem

Existing continuous glucose monitoring systems require complex user operations for attaching the sensor module to the skin, and the separate transmitter is often disposable, leading to inefficiency and environmental waste.

Innovation Solution

A sensor applicator assembly with a preinstalled sensor module and built-in battery, allowing easy attachment to the skin via a single operation of the applicator, and a semi-permanent transmitter connected to the sensor module for power, with the module and applicator designed as disposable units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the sensor module and applicator are provided as separate components requiring user assembly, then the user can perform multiple tasks manually, but the attachment process becomes complex and time-consuming

Engineering Contradiction:
Improveattachment process simplicityVSAvoidsystem integration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The sensor module is preinstalled in the applicator during manufacturing, merging two separate components into a single integrated assembly. This eliminates the need for users to manually assemble the sensor module and applicator, simplifying the attachment process to a single operation while maintaining clear functional boundaries between components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sensor module is preinstalled in the applicator before the user receives the device. This preliminary assembly action is performed during manufacturing, so the user never needs to perform this assembly step, reducing the attachment process to simply operating the pre-assembled unit

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If the transmitter is designed as disposable, then the system is simpler to manufacture and distribute, but it leads to economic inefficiency and environmental waste

Engineering Contradiction:
Improvetransmitter productionVSAvoidtransmitter waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The system is segmented into disposable components (sensor module and applicator) and a reusable component (transmitter). The disposable parts are designed for single use and then discarded, while the transmitter is designed to be reused multiple times by connecting to different sensor modules, reducing waste and improving economic efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The disposable sensor module and applicator are discarded after single use, while the transmitter is recovered and reused. This selective discarding and recovery strategy minimizes waste of expensive components while maintaining system functionality through replacement of the disposable sensor module

Inventive Principle:
Principle #34Discarding and recovering

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.
