Segmented Clamping Ring for Pipe Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe connection devices for spigot and socket ends face challenges in providing pull-out protection and sealing effectiveness across varying pipe diameters, are sensitive to dirt, and require time-consuming screw-based tensioning, limiting adaptability and ease of use.
Innovation Solution
The pipe connection device features pins and recesses allowing for displacement and rotation of links, a sealing ring that covers the entire circumference, and a quick-clamping mechanism using conical surfaces and screw elements, along with a dirt-sealing lip and grip elements to ensure secure, adaptable, and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw-based tensioning is used to clamp the clamping ring, then secure connection is achieved, but installation time increases significantly
Solution Approach 1:
The clamping ring is divided into multiple independent links connected by pins and recesses, allowing each link to be adjusted and clamped independently rather than requiring uniform tightening of the entire ring with multiple screws
Solution Approach 2:
The links are designed with mobility relative to each other through pins in elongated recesses, enabling the clamping ring to adapt dynamically to different pipe diameters and maintain effective clamping without requiring extensive screw tightening
2Strength
If the clamping ring is made rigid to maintain structural integrity, then connection strength is improved, but adaptability to different pipe diameters decreases
Solution Approach 1:
The clamping ring is segmented into multiple links that can move relative to each other, providing adaptability to different pipe diameters while maintaining overall structural integrity through the interconnected pin-and-recess mechanism
Solution Approach 2:
The links are designed with controlled mobility through pins in elongated recesses, allowing the clamping ring to dynamically adjust its inner diameter to match different pipe sizes while maintaining sufficient clamping force for secure connections
3Adaptability or versatility
If the clamping ring is made flexible to adapt to different diameters, then adaptability is improved, but structural integrity and clamping force decrease
Solution Approach 1:
The clamping ring is divided into links that provide flexibility for diameter adaptation while the pin connections maintain structural coherence, allowing each link to move independently without compromising the overall clamping structure
Solution Approach 2:
The links are designed with controlled mobility through pins in elongated recesses, enabling the clamping ring to adapt to different diameters while the interconnected structure maintains sufficient clamping force through the collective action of all links
4Reliability
If conventional sealing methods are used, then sealing is achieved, but sensitivity to dirt and contamination increases
Solution Approach 1:
The sealing function is extracted from the clamping mechanism itself and implemented through a separate sealing ring, allowing the clamping links to focus on mechanical fastening while the sealing ring provides dedicated sealing that is less sensitive to dirt and contamination

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, adaptable, and easy-to-use pipe connection that withstands high pull-out forces and pressures, maintains sealing integrity, and reduces installation time by utilizing a quick-clamping system that minimizes the need for extensive screw tightening.
Implementation Method 1
This is usually achieved via wedge surfaces, whereby a ring is pressed against the shank end in a self-locking manner during a pull-out movement.
Implementation Method 2
a ring is pressed against the shank end in a self-locking manner during a pull-out movement
