Blood Glucose Sensor Applicator Assembly for Stable Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood glucose monitoring systems face challenges in stable coupling and decoupling operations between the applicator and the body-attachable unit, leading to complications during attachment and unstable attachment to the body, along with complex manufacturing processes.
Innovation Solution
A sensor applicator assembly featuring an upper and lower frame with identical peripheral surfaces and a plunger mechanism, including a locking hook and elastic members, allows for stable coupling and decoupling without separate engaging parts, enhancing design flexibility and simplifying the body-attachable unit's housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If various elements are used for coupling and decoupling between applicator and body-attachable unit, then coupling operations can be performed, but the configuration becomes complicated and manufacturing becomes difficult
Solution Approach 1:
The patent merges the coupling and decoupling functions into a single integrated element structure. The body-attachable unit's housing directly engages with the applicator through complementary geometric features (protrusions and recesses), eliminating the need for separate coupling mechanisms. This integration simplifies the overall configuration while maintaining reliable coupling and decoupling operations.
Solution Approach 2:
The housing of the body-attachable unit serves multiple functions: it protects internal components, provides structural support, and enables coupling with the applicator through its peripheral surface design. This multi-functionality reduces the need for additional dedicated coupling elements, thereby simplifying the overall device configuration.
2Reliability
If various elements are used for coupling and decoupling between applicator and body-attachable unit, then coupling operations can be performed, but manufacturing becomes complex and design modifications are difficult
Solution Approach 1:
The coupling features are integrated directly into the housing mold of the body-attachable unit, combining the housing and coupling elements into a single manufacturing process. This eliminates the need for separate manufacturing steps for coupling elements, simplifying production and enabling easier design modifications through straightforward mold updates.
3Reliability
If the body-attachable unit is designed with separate engaging parts, then coupling can be achieved, but the housing form becomes complex and inner space is reduced
Solution Approach 1:
The coupling features are formed as integral parts of the housing structure, merging the housing and coupling elements into a unified design. This eliminates the need for separate engaging parts that would occupy additional space, thereby maximizing the inner space available for sensor components while maintaining reliable coupling through the housing's peripheral surface geometry.
