Analyte Sensor Bottom Case for One-Step Transmitter Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body fluid analyte detection devices require multiple steps and complex fastening structures for separating the transmitter from the bottom case, negatively impacting user experience.
Innovation Solution
The device features a bottom case with a force-receiving portion that fails when a force is applied in one direction, allowing the first and second fastener parts to separate, simplifying the separation process and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex fastening structure is used to securely attach the transmitter to the bottom case, then the connection reliability is improved, but the separation operation becomes more difficult and requires multiple steps
Solution Approach 1:
The bottom case is segmented into a fixed portion and a force-receiving portion. The fastening structure is divided into a first fastener part on the transmitter and a second fastener part on the bottom case. This segmentation allows the force-receiving portion to fail in a controlled manner when force is applied, enabling easy separation while maintaining secure attachment during use.
Solution Approach 2:
The second fastener part on the bottom case is designed as a disposable component that fails after use. When the sensor's battery is depleted or the sensor needs replacement, the bottom case with its second fastener part is discarded, and a new bottom case is used. This eliminates the need for complex separation operations as the entire bottom case assembly is replaced.
2Strength
If multiple fastening points are used to secure the transmitter, then the connection strength is improved, but the number of separation steps increases
Solution Approach 1:
Multiple fastening points are implemented through multiple second fastener parts distributed on the bottom case, providing strong connection strength. However, the force-receiving portion is designed to fail in a controlled manner when force is applied, allowing all fastening points to be released simultaneously in a single separation action rather than requiring sequential release of each fastening point.
Solution Approach 2:
The bottom case with multiple fastener parts is designed as a disposable component. After the sensor completes its service life, the entire bottom case assembly is discarded along with the depleted battery, eliminating the need for time-consuming separation operations to retrieve and reuse the transmitter.

AI summary
A body fluid analyte detection device, includes: a transmitter, provided with at least one first fastener part; a bottom case, provided with at least one second fastener part corresponding to the first fastener part, and the bottom case including at least one fixed portion and at least one force-receiving portion. When separating the bottom case and the transmitter, the fixed portion is fixed and a force is applied to the force-receiving portion in one direction, separating the bottom case and the transmitter. The body fluid analyte detection device further includes a sensor connected with the transmitter to transmit the parameter signal; and a battery assembled in the bottom case or in the transmitter. The part holding the battery is the battery portion. A force is applied to the force-receiving portion in only one direction to make the bottom case fail and thereby separating the transmitter and the bottom case, simplifying user action and enhancing user experience.
