Pipe Clamp Screw Joint for Variable-Diameter Friction Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe clamps for fastening pipes, particularly downpipes, to walls often fail to achieve a secure hold due to limited elasticity of pressure elements and varying pipe diameters, leading to potential detachment and design issues such as dirt accumulation and injury risks.
Innovation Solution
A pipe clamp design featuring arc-shaped clamping legs with radially inward folds connected by a screw mechanism, allowing adjustable frictional engagement to accommodate varying pipe diameters and providing a secure hold through a C-shaped configuration with elastic pressure elements for enhanced grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the elasticity of pressure elements is limited, then the structure remains simple, but the clamp fails to achieve sufficient tight frictional fit on pipes with varying outer diameters
Solution Approach 1:
The distance between the two clamping arms is made adjustable through a threaded connection element, allowing the clamp to dynamically adapt to pipes with varying outer diameters and maintain optimal frictional fit without requiring highly elastic pressure elements
2Device complexity
If radially outwardly bent flanges are used for connection, then the clamping mechanism can be simplified, but the design becomes visually unappealing and creates dirt accumulation points and injury risks
Solution Approach 1:
Instead of using radially outwardly bent flanges that protrude outward, the invention uses radially inwardly directed bends that fold inward toward the pipe, eliminating visual defects and harmful factors while maintaining the simplified clamping mechanism
Applied Scientific Principles
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 pipe clamp ensures a secure and adjustable frictional hold on pipes of varying diameters, preventing detachment and improving aesthetics by minimizing dirt accumulation and injury risks, while allowing easy installation and adjustment.
Implementation Method 1
lined internally with elastic pressure elements that are sufficiently flexible to lock the snap connection
Implementation Method 2
the two bends are clamped against one another in the circumferential direction by means of a screw connection... so that a tube is held in a frictional manner by the clamping legs
