Pipe Clamp Overlap Band Structure for Higher Holding Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamps, such as tensioning straps and hose clamps, suffer from limited holding force and require strong threaded bolts to secure pipes, making them inefficient and cumbersome.
Innovation Solution
A clamping band with a continuous recess allowing one end to pass through in the radial direction, forming a self-locking mechanism with overlapping layers that increase holding force through static friction, and utilizing a tangential tensioner for easy tightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional tensioning straps or hose clamps are used to secure pipes, then the connection can be achieved, but the holding force is limited and strong threaded bolts are required
Solution Approach 1:
The clamp is segmented into multiple functional components: a clamping band with recesses for flexibility, overlapping layers for friction-based holding, and a tensioning unit for force application. This segmentation allows each component to contribute specifically to increasing holding force while maintaining manageable structural complexity.
Solution Approach 2:
The clamp employs a nested structure where the clamping band wraps around the pipe multiple times, with overlapping layers nested within each other. The tensioning unit is nested within the band structure, with the tongue passing through recesses in the band. This nesting maximizes the use of space and material efficiency.
2Force
If strong threaded bolts are used to secure the clamp, then sufficient holding force is achieved, but the device becomes cumbersome and inefficient
Solution Approach 1:
The clamp is designed to be self-tensioning through the interaction between the tongue and the recesses in the clamping band. As the band wraps around the pipe and the tongue engages with the recesses, the structure automatically generates tension and secures itself without requiring complex threading or multiple fastening operations.
Solution Approach 2:
The clamp transitions from a static structure to a dynamic tensioning system where the band can be adjusted and tightened progressively. The tensioning unit allows for dynamic adjustment of the clamping force, enabling easy operation while achieving high holding force through controlled tensioning rather than rigid bolt fixation.
3Force
If the clamping band is wrapped multiple times around the pipe, then holding force increases through overlapping layers, but the band length and device complexity increase
Solution Approach 1:
The clamping band is designed as a flexible thin-walled structure that can wrap around the pipe multiple times without excessive material consumption. The flexibility of the band allows it to conform to the pipe geometry and create overlapping layers that generate friction-based holding force, while the thin-film design minimizes the overall material length required.
Solution Approach 2:
The clamp utilizes the radial dimension by wrapping the band around the pipe in multiple circumferential layers. This dimensional approach allows the holding force to be increased through the radial overlap of layers rather than requiring proportional increases in band length, efficiently converting circumferential wrapping into radial clamping pressure.
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 clamping band achieves a significantly higher holding force, reducing the need for strong bolts and allowing secure pipe connections with a simpler mechanism, enhancing stability under internal pressure.
Implementation Method 1
In the overlapping region, when the tensioning band is pressed onto the pipe, a radially outer region or section of the tensioning band presses against an underlying region or section of the tensioning band. Static friction can form in the overlapping region, so that the holding force is increased when the tensioning clamp is pressed onto the pipe.
