Hydraulic Coupler Eject Lever for Quick Tool Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic coupling devices do not efficiently aid in ejecting male hydraulic couplers from female couplers, leading to difficulties in quick and efficient detachment of tools or implements from vehicles.
Innovation Solution
A female coupler with a mechanical ejector system, comprising a lever and rod mechanism that pivots to depress a release pin of the male coupler, facilitating its ejection from the female housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a push-pull connect female coupler with sliding outer sleeve is used, then quick connection is achieved, but ejection of male coupler becomes difficult
Solution Approach 1:
The ejection function is segmented from the connection function. The mechanical ejector is a separate component with its own lever and rod mechanism that independently handles the ejection task, while the sliding outer sleeve mechanism continues to handle connection. This segmentation allows each mechanism to be optimized for its specific function without interfering with the other.
Solution Approach 2:
The mechanical ejector provides self-service ejection capability. Once the connection is made, the ejector mechanism can be activated independently to automatically depress the release pin and eject the male coupler, without requiring the operator to manually manipulate the connection mechanism in reverse.
2Device complexity
If no mechanical ejection aid is provided, then device complexity is reduced, but ejection efficiency decreases
Solution Approach 1:
The mechanical ejector provides self-service ejection capability. Once the connection is made, the ejector mechanism can be activated independently to automatically depress the release pin and eject the male coupler, without requiring the operator to manually manipulate the connection mechanism in reverse.

Function Achieved in This Case
The mechanical ejector system provides a reliable and efficient means to eject male couplers from female couplers, enhancing the detachment process and reducing operational effort.
Implementation Method 1
a mechanical ejector that is moveably connected to the female housing. The mechanical ejector includes a lever pivotally connected to the female housing at a first pivot point and a rod pivotally connected to the lever at a second pivot point rearwardly of the first pivot point
