Fluid Connector Verification Cap for Secure Connection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid connection assemblies lack a reliable mechanism to verify the complete and secure connection of fluid connectors, leading to potential fluid leaks and component failure.
Innovation Solution
A verification device is integrated into a locking assurance cap, providing visual and/or electronic signals through QR codes or RFID tags to confirm the connection status, ensuring a secondary verification mechanism is triggered only when the connection is fully secured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a retaining mechanism is used to secure the tube to the connector body, then the connection strength is improved, but there is no verification mechanism to confirm proper connection
Solution Approach 1:
The patent implements a verification device that provides feedback on the connection status. When the locking assurance cap is properly engaged on the connector body, the verification device activates to indicate through visual (colored band) or electronic (LED, RFID, QR code) signals that the connection is secure. This feedback mechanism ensures that the retaining mechanism is functioning correctly and the tube is properly secured.
Solution Approach 2:
The verification device acts as an intermediary between the retaining mechanism and the user. It translates the mechanical engagement of the locking assurance cap into observable signals that confirm proper connection. The verification device includes components such as a colored band, LED indicators, or electronic tags that serve as intermediaries to communicate connection status without requiring direct inspection of the retaining mechanism.
2Reliability
If visual or electronic verification signals are added to confirm connection status, then connection verification reliability is improved, but device complexity increases
Solution Approach 1:
The verification device is segmented into separate functional components: the locking assurance cap, the verification indicator (colored band, LED, or electronic tag), and the activation mechanism. This segmentation allows each component to perform its specific function independently, simplifying the overall design and manufacturing while maintaining verification reliability.
Solution Approach 2:
The patent employs simple, inexpensive verification indicators such as colored bands or disposable electronic tags that provide verification functionality without requiring complex or expensive mechanisms. These components are designed to be cost-effective and easily replaceable, reducing overall device complexity while maintaining reliable connection verification.
