Tilting Threaded Fluid Connector for Misalignment Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid connectors require matching thread configurations, limiting their versatility in connecting different fluid ports and failing to maintain a seal under side loads or misalignment.
Innovation Solution
A fluid connector design featuring a tilting sleeve, mismatched external and internal threads, a single piece collet assembly, and opposing handles or fluid actuation, allowing for connection with various port configurations while maintaining a seal through a seal between the sleeve and collet assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If threads on the connector are designed to match the threads on the threaded port, then reliable connection and sealing are achieved, but the connector can only be used with ports having matching thread configurations
Solution Approach 1:
The connector separates the threading function from the sealing function. The collet assembly with external threads provides mechanical engagement with internal threads of various configurations, while a separate seal element provides the sealing interface. This segmentation allows each component to be optimized independently - threads for versatility and seal for reliability.
Solution Approach 2:
The collet assembly acts as an intermediary between the connector body and the threaded port. It provides a standardized interface that can accommodate various thread configurations through its gripping mechanism, while the separate seal element ensures reliable sealing. The collet assembly mediates between the need for thread compatibility and sealing reliability.
2Adaptability or versatility
If the connector is designed with fixed alignment, then sealing is maintained, but the connector cannot accommodate side loads or misalignment
Solution Approach 1:
The connector incorporates dynamic elements that allow movement and adjustment. The collet assembly can expand and contract to accommodate misalignment, and the seal element is positioned to maintain sealing engagement even when the connector experiences side loads or angular deviations from perfect alignment.
Solution Approach 2:
The seal element functions as a flexible component that can deform to maintain sealing contact. This flexibility allows the seal to accommodate misalignment and side loads while maintaining its sealing function, preventing fluid leakage under varying operational conditions.
3Adaptability or versatility
If multiple connector designs are created for different port configurations, then compatibility is achieved, but device complexity increases
Solution Approach 1:
The connector is designed as a universal interface that can connect to multiple different port configurations. The collet assembly with its external threads and gripping mechanism can engage with various internal thread types, while the standardized seal interface maintains consistent sealing performance across different applications, eliminating the need for multiple specialized connector designs.

AI summary
A fluid connector that connects a first fluid system with a fluid port of a second fluid system for transferring fluids, including gaseous or liquid fluids, between the first and second fluid systems. The fluid connector can be used with differently configured, non-matching threaded fluid ports and allow for misalignment/tipping of the fluid connector to maintain a seal with the fluid port.
