Fluid Line Connector With Elastic Unlocking Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for fluid lines require high actuating forces to unlock, making them difficult to use tool-free and inefficient for secure connections in applications like motor vehicles and ventilation technology.
Innovation Solution
A connector design featuring a radially elastic spring geometry connected to a rotating ring, with inclined guide planes and spring elements on both sides, allowing for low-force operation and secure locking, suitable for use in motor vehicles and charge-air technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating ring with closure geometry is used to lock the connector, then secure connection is achieved, but high actuating forces are required to unlock
Solution Approach 1:
The patent applies the dynamics principle by introducing a spring element that transforms the static locking mechanism into a dynamic one. The spring element (19) is connected to the rotating ring (15) and enables the connecting element (18) to move radially during the unlocking process. This dynamic mechanism allows the closure geometry (24) to be moved out of engagement with the securing geometry (105) using low actuating forces, while still maintaining secure connection when locked
2Reliability
If high actuating forces are required to unlock, then secure locking is achieved, but tool-free operation becomes difficult
Solution Approach 1:
The patent applies the self-service principle through the spring element (19) that automatically provides the necessary radial movement of the connecting element (18) during unlocking. The spring element stores and releases energy to assist in moving the closure geometry (24) out of engagement, making the unlocking process self-assisting and enabling easy one-handed operation without requiring tools or excessive force

AI summary
A connector for a fluid seal, having an annular housing with a first end and a second end and a rotating ring. The rotating ring is arranged at the second end and the rotating ring has at least one connecting element that is in engagement with at least one retaining geometry and with at least one guide geometry. The guide geometry allows the at least one connecting element to move in a radial direction when the rotating ring is rotated relative to the housing. The at least one connecting element is connected to the rotating ring by at least one radially elastic spring geometry.
