Leak-Free Pipe Socket Mounting via Clamping and Anti-Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe socket arrangements in dialysis stations suffer from leakage issues due to loose threaded connections and inflexible mounting options, making it difficult to adapt to varying pipe orientations without significant work.
Innovation Solution
Incorporating a clamping element on the pipe socket and an anti-rotation element on the quick coupling, which are clamped between the mounting frame, preventing rotation and ensuring a secure, leak-free connection in any angular position without the need for threaded holes on the flange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded holes are used to fasten the pipe socket to the mounting frame, then the connection is secure, but the assembly becomes inflexible and difficult to adapt to varying pipe orientations
Solution Approach 1:
The fastening system is divided into separate functional elements: the mounting frame with pre-drilled holes, the pipe socket with flange, and the clamping element. This segmentation allows the mounting frame to provide structural support while the clamping element provides adaptable fastening, resolving the contradiction between secure connection and mounting flexibility.
Solution Approach 2:
The clamping element introduces dynamic fastening capability, allowing the pipe socket to be securely attached to the mounting frame at various angular positions. The clamping mechanism can be adjusted and tightened at any orientation, providing both security and adaptability that fixed threaded holes cannot achieve.
2Reliability
If threaded connections are used for the quick coupling, then the connection is secure, but the threaded seat becomes loose over time due to connection/disconnection cycles
Solution Approach 1:
The anti-rotation element prevents rotational movement of the quick coupling relative to the pipe socket before any loosening can occur. By eliminating the rotation that causes threaded seat loosening, the system maintains secure connections over extended periods of repeated connection and disconnection cycles.
Solution Approach 2:
The anti-rotation element acts as an intermediary between the quick coupling and the pipe socket, preventing direct rotational interaction that would otherwise cause the threaded seat to loosen. This intermediary component protects the threaded connection from degradation while still allowing secure attachment.
3Ease of manufacture
If the pipe socket is fixed in a single direction with pre-threaded holes, then the assembly is simple, but it cannot adapt to pipes running at various angles
Solution Approach 1:
The mounting frame with clamping element serves multiple functions: it provides structural support, enables secure fastening, and allows adaptation to various pipe orientations. This universal mounting system replaces the need for different mounting configurations for different angles, maintaining simplicity while providing versatility.

AI summary
Disclosed is an assembly for diverting a liquid from a pipe or feeding a liquid into a pipe that is connected to a laterally extending pipe connection. The free end of said pipe connection is fitted with a flange while a quick-fitting pipe coupling is screwed into the pipe connection. The pipe connection is fastened to a mounting frame, through which the quick-fitting pipe coupling extends. The disclosed assembly is characterized in that a clamping element rests against the flange on the pipe connection, a locking element rests against the other side of the flange on the quick-fitting pipe coupling, the mounting wall rests against the other side of the locking element, and the clamping element is braced with the mounting frame.
