RFID Fluid Connection Assembly for Secure Hose Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a connection verifier that uses RFID technology to ensure a fluid connection is securely connected, as existing technologies lack effective methods to verify the proper engagement of fluid connectors and hoses.
Innovation Solution
The implementation of a radio-frequency identification (RFID) fluid connection system, which includes a tube with a radially outward-facing surface, an RFID assembly connected to this surface, and at least one contact electrically connected to the RFID tag. The RFID assembly is arranged proximate to a shoulder on the tube, and the contacts are designed to change state based on the connection status, allowing the RFID tag to indicate whether the connection is proper or not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fluid connectors are used without verification mechanisms, then the device complexity is low, but the reliability of connection is insufficient and leaks may occur
Solution Approach 1:
The patent replaces mechanical verification methods with RFID electromagnetic field-based verification. The RFID tag and reader system provides automated connection status detection without requiring complex mechanical sensors or switches, thus improving reliability while maintaining relatively simple device structure.
Solution Approach 2:
The patent introduces an RFID tag as an intermediary element between the fluid connector and the verification system. This tag serves as a mediator that carries connection status information and enables wireless communication with the reader, allowing reliable verification without direct mechanical or electrical contact.
2Reliability
If manual connection verification is performed, then the device complexity is low, but the loss of time for verification and potential leaks increases
Solution Approach 1:
The patent replaces manual visual inspection or mechanical gauge verification with automated RFID electromagnetic detection. The reader automatically queries the RFID tag to determine connection status, providing instant verification without requiring human intervention or time-consuming manual checks.
Solution Approach 2:
The patent implements a feedback mechanism where the RFID reader receives real-time connection status information from the RFID tag and can provide immediate feedback to the operator or system. This automated feedback loop enables rapid verification and prompt corrective action if connection issues are detected.
3Difficulty of detecting and measuring
If RFID assembly is added to the fluid connector, then connection verification capability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent replaces complex mechanical sensing assemblies with a compact RFID tag and reader system. The RFID components are significantly smaller and simpler to manufacture than traditional mechanical sensors, switches, or gauges, while providing superior connection status detection capability through electromagnetic field interaction.
Solution Approach 2:
The RFID tag serves multiple functions: it identifies the specific fluid connector, stores connection status information, and enables wireless communication. This multi-functionality reduces the need for separate components, simplifying the overall manufacturing process while maintaining advanced detection capabilities.
