Quick Fluid Connectors With Modular Sensors for Connection Confirmation
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, as they rely on piston movement assumptions rather than actual connection confirmation.
Innovation Solution
The implementation of modular connection state sensors that monitor the movement of key elements, such as cylindrical sleeves or pistons, to accurately determine the connection state before fluid flow initiation, with optional visual feedback through translucent housings and potential future integration of wireless capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If piston movement is used to estimate connection state, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent replaces mechanical connection state detection with optical sensing. A sensor detects the position of a magnet attached to the piston through non-contact magnetic field sensing, eliminating the need for direct mechanical contact while improving measurement accuracy. This allows precise detection of piston position and connection state without adding complex mechanical linkages.
2Adaptability or versatility
If modular sensors are implemented, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent designs a universal magnet assembly that can be attached to various piston types across different connector models. The magnet serves multiple functions: it enables optical sensing for connection state detection, provides positional reference, and works with different piston configurations. This universal approach allows a single sensor design to accommodate multiple connector types without requiring complex model-specific adaptations.
3Productivity
If connection state is not accurately confirmed, then productivity increases due to faster operation, but reliability deteriorates
Solution Approach 1:
The patent implements preliminary connection state verification before fluid transfer begins. The optical sensor detects piston position and confirms proper connection establishment in advance, providing a verification signal that ensures reliable coupling. This preliminary check prevents premature fluid transfer that could cause disconnection, while the quick detection mechanism maintains operational efficiency.

AI summary
Quick connect fluid connectors with modular connection state sensors removably or detachably mounted thereon. Each modular connection state sensor is configured to sense a connection state of the fluid connector it is mounted on. The connection state sensor 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 connection state sensor senses movements of one or more elements of the quick connect fluid connector that is involved in the actual connection of the fluid connector to the second fluid system. The elements that are sensed can be, for example, one or more cylindrical sleeves of the fluid connector or a piston of the fluid connector. Therefore, the connection state of the fluid connectors can be determined accurately.
