Coupling Part Axial Actuation for Tool-Free Connector Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling parts for connector assemblies are difficult to handle and require additional tools for releasing the plug-in part, due to complex structures and the need for lateral space to move locking elements into their release position.
Innovation Solution
A coupling part with a coaxially movable actuating element that widens the locking elements transversely, allowing easy release of the plug-in part without additional tools, featuring a simple structure with fewer components and a spring element connecting the locking elements for automatic locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If locking elements are moved laterally out of the receptacle for release, then the plug-in part can be released, but sufficient lateral space is required and handling becomes difficult
Solution Approach 1:
The locking elements are moved from lateral displacement to axial displacement. The actuating element moves coaxially to the longitudinal axis of the receptacle, transferring the locking elements from a locking position to a release position along the axial direction rather than laterally, thereby eliminating the need for sufficient lateral space.
Solution Approach 2:
Instead of moving the locking elements outward laterally to release the plug-in part, the invention inverts the mechanism by moving the actuating element axially to push the locking elements inward or reposition them axially, achieving release without lateral space requirements.
2Ease of operation
If additional tools are used to move locking elements, then release can be achieved, but handling complexity increases
Solution Approach 1:
The actuating element is designed to be directly operable by the user without requiring additional tools. The user can grip and move the actuating element axially to transfer the locking elements between locking and release positions, achieving tool-free operation.
Solution Approach 2:
The actuating element integrates multiple functions: it serves as both the operating interface for the user and the mechanism for transferring the locking elements. The actuating element combines the functions of operation transmission and locking element actuation into a single integrated component.
3Ease of operation
If locking elements are held in release position, then easy removal is enabled, but additional components are required
Solution Approach 1:
The locking elements are designed to be dynamically positionable between locking and release positions through axial movement of the actuating element. The system transitions from a static locked state to a dynamic release state without requiring additional components to hold the release position, as the actuating element itself maintains the positional state.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides simple and tool-free handling, reduces the risk of faults, and allows for easy assembly and disassembly of the coupling part, ensuring a secure and fluid-tight connection while minimizing mechanical stress on sealing components.
Implementation Method 1
The locking elements can be moved into the release position against a resilient restoring force. This has the advantage that they automatically move into their locked position if no actuating force acts on the locking elements.

AI summary
The invention relates to a coupling part for a plug connector arrangement, whereby the coupling part comprises a coupling body provided with a receiving element, wherein a plug-in part can be inserted in the direction of the longitudinal axis of the receiving part for producing a fluid-tight connection. The coupling part comprises two locking elements which are arranged at a distance in relation to each other which, in a locking position, enter laterally opposite each other into the receiving element for engaging the plug-in part from underneath and which can be displaced for releasing the plug-in part into a released position. The aim of the invention is to improve the coupling part in such a manner that it is easy to handle and as a result, the coupling part comprises an actuation element which can be displaced in relation to the coupling body. The locking elements can be displaced by displacing the actuation element from the locking position into a released position, wherein there is a greater distance therebetween than in the locked position.
