Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current continuous glucose monitoring (CGM) devices are bulky, which interferes with daily activities and increases the risk of data loss due to the device being easily bumped or caught.
Innovation Solution
A micro-analyte detection device with a sensor structure embedded in the bottom case, where the sensor base is completely embedded, reducing the overall thickness and eliminating the need for extra space in the transmitter.

1Length of stationary object
If the sensor structure is completely embedded in the bottom case, then the thickness of the detection device is reduced, but the manufacturing precision requirement increases
Solution Approach 1:
The sensor base is completely embedded within the bottom case, with the fastener parts nested within the mounting hole structure. This nesting arrangement allows the sensor structure to be fully contained within the bottom case thickness, eliminating protrusions and reducing the overall device thickness without requiring additional external fastening components.
Solution Approach 2:
The mounting hole is designed with specific local features including a first fastener part at its edge and contoured edges that match the sensor base. This localized structural design ensures precise embedding of the sensor base while maintaining the overall compactness of the device. The matching contours create an interlocked structure that achieves both compactness and manufacturing feasibility.
2Length of stationary object
If the sensor base is completely embedded in the bottom case, then the device thickness is reduced, but the device complexity increases
Solution Approach 1:
The mounting hole integrates multiple functions into a single structure: it provides the embedding cavity for the sensor base, contains the first fastener part for securing, and features contoured edges for alignment and interlocking. This merging of functions reduces the need for separate components and simplifies the overall assembly process while achieving the compact embedded design.
Solution Approach 2:
The bottom case structure serves multiple purposes: it houses the sensor structure, provides the mounting mechanism through the integrated mounting hole with fastener parts, and maintains the compact form factor. The mounting hole itself performs multiple functions including positioning, fastening, and structural integration, reducing the need for additional specialized components.
