Biosensing Meter Connector with Inverted R-Angle Contacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for biosensing meters are prone to scratching electrodes of electrochemical biosensor strips, lack variability to accommodate different strip sizes, and do not efficiently reduce meter volume, leading to suboptimal connection accuracy and sample handling.
Innovation Solution
A connector design with a sliding base and terminal components arranged in a specific configuration to provide uniform contact and an ejecting function, featuring a transverse opening, inverted R-angle contact points, and gold plating to prevent scratching, allowing for reduced size and increased functionality without additional ejecting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional terminal components are used to connect electrodes, then electrical connection is achieved, but the electrodes are scratched easily and connection accuracy deteriorates
Solution Approach 1:
The terminal components are designed with inverted R-angle contact points (curved surfaces) instead of sharp edges, which reduces stress concentration and prevents scratching of the electrode surfaces during insertion and connection, thereby improving connection reliability while protecting the electrodes
2Volume of moving object
If conventional connector structure is used, then basic connection function is provided, but the connector size cannot be reduced to match smaller biosensing meters
Solution Approach 1:
The terminal components are arranged in a multi-dimensional configuration (left to right, top to bottom, front to back) within the connector body, allowing efficient space utilization and enabling the connector to accommodate different strip sizes while maintaining a compact overall structure
Solution Approach 2:
The connector is designed with a standardized interface that can accommodate electrochemical biosensor strips of various sizes, providing universal adaptability across different strip configurations while maintaining a compact form factor suitable for smaller biosensing meters
3Manufacturing precision
If electrodes are pushed from top to down by terminal components, then electrical connection is established, but the push force is not uniform and connection accuracy deteriorates
Solution Approach 1:
The inverted R-angle design of the terminal components distributes the contact force more uniformly across the electrode surface during insertion, preventing localized stress concentration and ensuring consistent electrical connection accuracy
