Chamfered Hose Coupling Part for Easier Alignment and Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose coupling parts are difficult to position and uncouple, especially in emergency situations like fires, due to misalignment, requiring excessive effort and potentially preventing effective uncoupling.
Innovation Solution
A coupling part with an annular element and hook-like elements featuring a chamfered wall surface at an angle to the main flow direction, along with a locating surface and locking mechanism, facilitates easier alignment and uncoupling, reducing misalignment and weight while maintaining strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional coupling parts with hook-like elements are used, then the coupling can be formed, but the coupling parts are difficult to position and uncouple due to misalignment
Solution Approach 1:
The chamfered wall surface is pre-formed on the coupling part during manufacturing, creating a built-in alignment guide that automatically directs the coupling parts into proper alignment as they approach each other during coupling, preventing misalignment before it occurs
Solution Approach 2:
The chamfered wall surface introduces an asymmetric geometric feature at the coupling interface, where one surface is angled relative to the main axis. This asymmetry creates a self-aligning mechanism that guides the coupling parts into correct orientation, preventing the symmetric misalignment problems of conventional designs
2Ease of operation
If conventional coupling parts are used, then the coupling can be formed, but excessive effort is required to uncouple the parts
Solution Approach 1:
The chamfered wall surface is pre-configured to create a controlled separation path. As the coupling parts are pulled apart, the chamfer geometry automatically guides the separation process, preventing the parts from becoming jammed or misaligned during uncoupling, thereby reducing the force needed to separate them
3Reliability
If conventional coupling parts are used, then the coupling can be formed, but the coupling parts can be pulled out of alignment during uncoupling
Solution Approach 1:
The chamfered wall surface creates an asymmetric geometry that provides a preferred separation path during uncoupling. This asymmetric feature acts as a mechanical guide that prevents the coupling parts from being pulled out of alignment, ensuring they remain properly oriented even as force is applied to separate them

AI summary
A coupling part for a hose coupling, a hose coupling provided therewith and method for coupling a hose or hose part. The coupling part includes an annular element; a number of hook-like coupling elements arranged at or on the annular element and configured to engage on a corresponding coupling element of a corresponding coupling part for the purpose of forming a coupling; and a wall surface provided on the inward directed side of the hook-like coupling element and provided at an angle of chamfer to the main throughflow direction of the coupling part.
