Marine Fluid Connector with Separate Levers for Stronger Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fluid handling systems, existing connectors with integral locking levers and bodies face limitations in material selection due to the need for high ductility, compromising strength and optimizing material properties for the connection joint.
Innovation Solution
A connector design where the body, levers, and locking ring are separate components, allowing for material optimization based on specific functions, with levers pivoting within cradles and a locking ring using cams to move between latched and unlatched positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the connector body and locking levers are made integral, then the number of components is reduced and manufacturing is simplified, but material selection is compromised and cannot be optimized for connection joint strength
Solution Approach 1:
The connector is divided into separate components: the connector body and the locking levers are manufactured as distinct parts. This segmentation allows each component to be optimized independently - the body can use materials optimized for structural strength while the levers can use materials optimized for ductility and repeated deflection, thereby resolving the material selection compromise.
2Ease of operation
If high ductility materials are used for integral levers to enable regular deflection during connection and disconnection, then the levers can function properly, but the material cannot be optimized for strength of the connection joint
Solution Approach 1:
Different materials with different properties are assigned to different components based on their specific functional requirements. The locking levers use high-ductility materials (such as spring steel or ductile plastics) to enable repeated deflection during operation, while the connector body can use high-strength materials to optimize connection joint strength. Each component's material is locally optimized for its specific function.

AI summary
The specification discloses a marine fluid connection system including a fitting and a connector. The fitting is cylindrical and incudes a radially extending flange. The connector includes a cylindrical body, a plurality of levers on the body, and a locking ring on the body. The levers are movable between a latched position, in which the levers are closed on the flange to lock the connector on the fitting, and an unlatched position, in which the levers are open so that the connector may be removed from the fitting. The locking ring is axially movable with respect to the body to move the latches between their latched and unlatched positons.
