Analyte Sensor Housing for One-Direction Transmitter Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body fluid analyte detection devices require multiple steps and different directional forces to separate the transmitter from the bottom case, negatively impacting user experience.
Innovation Solution
The device features a bottom case that fails when a force is applied to its force-receiving portion in only one direction, separating the first and second fastener parts and reducing the number of steps required for separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fastener parts are used to secure the transmitter to the bottom case, then the connection reliability is improved, but the separation operation becomes more complex and requires multiple steps
Solution Approach 1:
The bottom case is segmented into a fixed portion and a force-receiving portion. The fastener parts are distributed across these segments, allowing the force to be concentrated on the force-receiving portion while maintaining secure connection through multiple fasteners. This segmentation enables reliable connection during normal use while facilitating easy separation when force is applied to the designated portion.
2Strength
If the bottom case is designed to be robust and durable, then the structural strength is improved, but the separation process requires more force and multiple steps
Solution Approach 1:
The bottom case exhibits local quality differentiation: the fixed portion maintains high structural strength to ensure durability and secure fastening, while the force-receiving portion is designed with reduced strength characteristics that enable easy separation. This localized weakness allows the overall structure to remain robust while facilitating simple one-directional separation.
3Strength
If the fastener parts are designed to provide strong connection, then the connection strength is improved, but the separation requires forces in multiple directions and multiple steps
Solution Approach 1:
The fastener parts are arranged asymmetrically with respect to the force-receiving portion. This asymmetric configuration allows all fasteners to be simultaneously disengaged when force is applied in the specific direction toward the force-receiving portion, reducing the separation process to a single step while maintaining strong connection during normal use.

AI summary
A body fluid analyte detection device, including: a transmitter(12,22), provided with at least one first fastener part(121,221); a bottom case(10,20), provided with at least one second fastener part(101,201) corresponding to the first fastener part(121,221), and the bottom case(10,20) comprises at least one fixed portion and at least one force-receiving portion, and when separating the bottom case(10,20) and the transmitter(12,22), the fixed portion is fixed and a force is applied to the force-receiving portion in one direction, separating the bottom case(10,20) and the transmitter(12,22); a sensor(113) is connected with the transmitter(12,22) to transmit the parameter signal; and a battery is assembled in the bottom case(10,20) or in the transmitter(12,22), and the part holding the battery is the battery portion(123,203).A force is applied to the force-receiving portion in only one direction to make the bottom case(10,20) fail and thereby separate the transmitter(12,22) and the bottom case(10,20), simplifying user action and enhancing user experience.
