Telescopic Pipe Clamp for Tool-Free Multi-Diameter Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe clamps require skill and strength to install, are not universally applicable, and often result in vibrations and noise due to inadequate diameter support, especially under difficult installation conditions like near ceilings.
Innovation Solution
A pipe clamp design featuring a threaded rod with a hold-down device that allows for adjustable contact pressure and easy installation without tools, using a threaded sleeve and intermediate sleeve for telescopic movement, enabling secure fitting of pipes with varying diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lower shell is rotated to close the pipe clamp, then the pipe can be secured, but the lower shell hits the inserted pipe requiring additional manipulation
Solution Approach 1:
The pipe clamp incorporates a flexible lower shell that can dynamically bend downward during rotation to clear the pipe, then return to its original position to secure the pipe. This dynamic flexibility eliminates the need for manual manipulation to complete the closing operation.
Solution Approach 2:
The lower shell automatically performs the necessary downward movement and rotation sequence without requiring external manipulation. The spring element provides self-service by automatically returning the lower shell to its secured position after it bends downward during closing.
2Adaptability or versatility
If the pipe clamp is designed for larger diameter pipes, then larger pipes can be accommodated, but the clamp requires considerable force resulting in pipe deformation
Solution Approach 1:
The flexible lower shell dynamically adapts its shape during closing, bending downward to clear the pipe and then returning to secure it. This dynamic action reduces the static force required to close the clamp on larger diameter pipes, preventing deformation while maintaining adaptability.
Solution Approach 2:
The pipe clamp's effective clamping parameters change during operation through the flexible lower shell's movement. The shell's flexibility allows the clamp to adjust its geometry based on pipe diameter, reducing required closing force across different sizes while maintaining secure holding.
3Adaptability or versatility
If the pipe clamp is designed for smaller diameter pipes, then smaller pipes can be accommodated, but the pipe is not held securely causing vibrations and noise
Solution Approach 1:
The flexible lower shell dynamically adjusts to smaller pipe diameters by bending downward during rotation and then returning to fully contact and secure the pipe. This ensures reliable holding of smaller pipes without vibrations or noise while maintaining adaptability across different sizes.
Solution Approach 2:
The clamp's contact parameters change dynamically through the flexible lower shell's movement, allowing optimal contact pressure to be achieved on smaller diameter pipes. The spring element ensures consistent securing force regardless of pipe size, eliminating vibrations and noise.
4Ease of operation
If the retainer is moved against the pipe and fixed with two fixing screws, then the pipe can be secured, but the installation requires tool engagement at various points
Solution Approach 1:
The pipe clamp merges the support function and fixing function into a single integrated flexible lower shell component. This eliminates the need for separate retainers and multiple fixing screws, allowing installation with a single manipulation sequence and reducing tool engagement points.
Solution Approach 2:
The flexible lower shell with spring element provides self-service by automatically returning to its secured position after bending downward during closing. This eliminates the need for manual tightening operations with screwdrivers, requiring only the initial rotation action.
