Fluid Connector Connection State Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick connect fluid connectors often fail to accurately determine the connection state, leading to potential disconnection under pressure, especially in high-pressure applications, due to assumptions based on piston movement rather than actual connection verification.
Innovation Solution
Incorporation of sensors to monitor the movement of elements within the fluid connector, such as cylindrical sleeves or pistons, to accurately determine the connection state by detecting magnetic fields of embedded magnets, ensuring a secure connection before fluid flow initiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connection state is determined by piston movement alone, then connection speed is improved, but connection reliability deteriorates
Solution Approach 1:
The patent implements feedback by using sensors to detect the actual connection state and provide real-time information to the control system. The sensor detects whether the connection member is properly engaged with the mating coupler, and this feedback information is used to confirm or prevent connection, ensuring reliable connection state determination while maintaining quick connect functionality.
2Reliability
If threading and un-threading is required for connection, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the traditional threaded mechanical connection system with a quick connect mechanism that uses a connection member and mating coupler. This substitution maintains connection reliability through proper mechanical engagement while dramatically improving ease of operation by eliminating the need for threading and un-threading, allowing rapid connection and disconnection.
3Reliability
If connection verification is performed before fluid flow, then connection reliability is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by performing connection verification automatically through sensors before fluid flow is initiated. The connection state is checked in advance using sensor detection, and only when proper connection is confirmed does the system allow fluid flow to begin. This preliminary verification ensures reliability while minimizing time loss by automating the process and integrating it into the connection sequence.

AI summary
Fluid connectors are described where one or more sensors are provided for sensing a connection state of the fluid connectors. The sensor(s) indicates that the fluid connector of the first fluid system is connected to the second fluid system prior to initiating fluid flow between the first and second fluid systems. The sensor(s) senses movements of one or more elements of the quick connect fluid connectors that are involved in the actual connection of the fluid connectors to the second fluid system. The elements that are sensed can be, for example, one or more cylindrical sleeves of the connector or a piston of the connector. Therefore, the connection state of the fluid connectors can be determined accurately.
