Rotary Locking Coupling for Fluid Hoses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling systems for hoses require complex assembly processes due to the handling of separate locking springs, which can be difficult and costly, especially in tight spaces, and are prone to component loss.
Innovation Solution
A coupling system where the locking mechanism is actuated by a rotational movement of the locking body, minimizing components and using radial elevations to secure the connection, allowing for simple and secure locking with minimal force and stress, and incorporating a sealing element for fluid-tight sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate locking spring is used to secure the connection, then the connection can be secured against axial movement, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The locking function is merged with the locking body itself. The locking body (20) integrates the locking mechanism directly into its structure, eliminating the need for a separate locking spring. The locking body can be rotated to engage and disengage locking elements (24) that directly secure the connection, combining what were previously separate components into one unified element.
Solution Approach 2:
The locking spring is extracted from the system entirely. By removing the separate locking spring component and replacing it with a rotationally actuated locking body that has integrated locking elements, the assembly process is simplified while maintaining the security function.
2Reliability
If a separate locking spring is used, then the connection can be secured, but the locking spring can be lost during assembly or delivery
Solution Approach 1:
The locking function is merged with the locking body itself. The locking body (20) integrates the locking mechanism directly into its structure, eliminating the need for a separate locking spring. The locking body can be rotated to engage and disengage locking elements (24) that directly secure the connection, combining what were previously separate components into one unified element.
3Reliability
If a separate locking spring is used, then the connection can be secured, but handling the locking spring becomes difficult and expensive in tight spaces
Solution Approach 1:
The locking function is merged with the locking body itself. The locking body (20) integrates the locking mechanism directly into its structure, eliminating the need for a separate locking spring. The locking body can be rotated to engage and disengage locking elements (24) that directly secure the connection, combining what were previously separate components into one unified element.
Solution Approach 2:
The manual manipulation of a flexible locking spring is replaced with a rotational movement of the rigid locking body. This substitution of mechanical action simplifies the assembly process, especially in tight spaces, as rotational movement is easier to control and requires less dexterity than manipulating a spring.
4Reliability
If multiple components are used in the coupling system, then the locking function can be achieved, but the number of assembly steps increases
Solution Approach 1:
The locking function is merged with the locking body itself. The locking body (20) integrates the locking mechanism directly into its structure, eliminating the need for a separate locking spring. The locking body can be rotated to engage and disengage locking elements (24) that directly secure the connection, combining what were previously separate components into one unified element.

Function Achieved in This Case
Enables quick and easy assembly with reduced component count, improved durability, and secure locking, while minimizing assembly forces and preventing component loss, ensuring a stable and reliable connection.
Implementation Method 1
The engagement element (24) is moved by a spring element (22) radially through the recess (14) into the interior of the coupling body (11) during the rotational movement
Implementation Method 2
The engagement element (24) can engage behind a first radial elevation (32) of the connection body (31) and block it in the longitudinal direction
