Hose Connector Assembly With Retaining Plate for Stress-Resistant Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose connector assemblies for sanitary fittings face complexity in production due to the need for threaded connections, which are difficult to assemble and prone to mechanical stresses, especially tensile stresses.
Innovation Solution
A hose connector assembly with a detent mechanism that allows hoses to be plug-fitted into receptacles with a retaining plate, enabling a secure connection that withstands mechanical stresses and allows for various orientations, reducing torsional stress, and optionally incorporating a screw sleeve for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hoses are provided with a thread which is screw-fitted into a respective hose receptacle, then a permanent and tight connection is established, but the assembly becomes complex in terms of production
Solution Approach 1:
The connection system is segmented into distinct functional components: the hose receptacle in the main body, the detachable retaining plate with receptacles, and the hoses with retaining edges. This segmentation allows each component to be manufactured independently and assembled through simple insertion movements, eliminating the need for complex threading operations while maintaining connection reliability.
Solution Approach 2:
Instead of screwing the hose into the receptacle (traditional approach), the invention inverts the approach by having the retaining plate with receptacles receive the hoses through lateral insertion, and the main body is then pressed against the retaining plate via a detent mechanism. This reversal of the assembly sequence simplifies production while ensuring a permanent and tight connection.
2Reliability
If hoses are fixed in a specific orientation, then a secure connection is achieved, but torsional stress is increased on the hoses
Solution Approach 1:
The retaining plate is designed to be adjustable and adaptable to different hose orientations. The lateral insertion movement allows hoses to be connected at various angles, and the detent mechanism on the mouth part can be pressed against the retaining plate at different positions, enabling dynamic adaptation to reduce torsional stress while maintaining a secure connection.
Solution Approach 2:
The invention allows changes in the orientation parameter of hose connection by enabling hoses to be plug-fitted into the hose receptacles in various orientations through the retaining plate mechanism, thereby optimizing the connection to minimize torsional stress on the hoses while maintaining connection stability.
3Adaptability or versatility
If multiple hoses are connected to a main body, then a complete connection system is achieved, but the assembly complexity increases
Solution Approach 1:
Multiple hoses are merged into a single integrated connection system through the common retaining plate. The retaining plate with multiple receptacles receives all hoses through lateral insertion, and the single detent mechanism on the mouth part secures the entire assembly by pressing against the retaining plate. This merging approach allows complete connection of multiple hoses while simplifying the assembly process compared to individual securing mechanisms for each hose.

AI summary
In the case of a hose connector assembly (1) it is provided for a retaining plate (15) to be used for axially fixing at least two hoses (6, 7, 8) in corresponding hose receptacles (3, 4, 5). The hoses (6, 7, 8) are insertable into respective recesses (16, 17, 18) of the retaining plate (15) by way of a lateral insertion movement (19), and the hoses (6, 7, 8) engage behind the recesses (16, 17, 18).
