Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe clamps with U-shaped grooves suffer from inward deformation and insufficient fixing force due to inadequate contact area between the pipe clamp and the pipe, especially when clamping pipes with different diameters.
Innovation Solution
A pipe clamp structure featuring a first U-shaped groove, a first movable member with a movable U-shaped groove, and a rotating member that engages threads to push the movable member toward the pipe, increasing the contact area and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cover and pipe only contact at two points, then the structure is simple, but the locking force is excessive causing pipe deformation
Solution Approach 1:
The cover is segmented into multiple contact points around its periphery edge, transforming the single two-point contact structure into multiple distributed contact points. This segmentation distributes the locking force across multiple locations, preventing excessive force concentration that causes pipe deformation while maintaining structural simplicity.
2Strength
If the arc of the U-shaped groove is consistent with the pipe, then the contact area increases improving fixing force, but the structure becomes complex requiring auxiliary accessories for different pipe diameters
Solution Approach 1:
The U-shaped groove employs a dynamic arc design where the arc radius can be adjusted or adapted to match different pipe diameters. This dynamic adjustment capability allows the groove to maintain optimal curve surface contact with pipes of varying sizes, ensuring sufficient fixing force without requiring multiple fixed-geometry auxiliary accessories.
3Device complexity
If the arc of the U-shaped groove is inconsistent with the pipe, then the structure is simple, but the contact area decreases resulting in insufficient fixing force
Solution Approach 1:
The U-shaped groove incorporates adjustable geometric parameters, specifically the arc radius, which can be modified to match the pipe diameter. This parameter change capability ensures that the groove maintains appropriate curve surface contact with pipes of different diameters, providing sufficient fixing force while keeping the overall structure relatively simple through a single adjustable component rather than multiple fixed accessories.
4Device complexity
If no outward supporting structure is added inside the U-shaped groove, then the structure is simple, but inward deformation occurs during cover rotation
Solution Approach 1:
The U-shaped groove incorporates preliminary outward supporting structures positioned inside the groove that proactively prevent inward deformation before it occurs during cover rotation. These supporting structures are pre-positioned to counteract the deformation tendency, maintaining groove stability and ensuring proper thread engagement without requiring complex external support mechanisms.
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 proposed pipe clamp structure effectively addresses the issues of inward deformation and insufficient fixing force by enhancing the contact area between the pipe clamp and the pipe, ensuring secure clamping of pipes with varying diameters.
Implementation Method 1
The first rotating member is pushed toward the first movable member, and the first movable U-shaped groove is pushed toward the pipe
Implementation Method 2
the arc of the U-shaped groove is consistent with that of the pipe, the U-shaped groove and the pipe form a curve surface contact, which can increase the friction force between the pipe clamp and the pipe to securely fix together

AI summary
A pipe clamp structure for clamping a pipe includes: a first cylindrical base having first and second end circular surfaces, a first cylindrical side surface provided with a first thread at an outside thereof, and a first U-shaped groove; a first movable member having a first end with a first movable U-shaped groove and a second end; and a first rotating member having a first cylindrical accommodating part provided with a second thread therein. The first movable U-shaped groove is coupled with the first cylindrical base to form a first clamping space for clamping the pipe. The first cylindrical accommodating part is sleeved at the outside of the first cylindrical side surface; and the first thread and the second thread are engaged with each other. The first clamping space is reduced to clamp the pipe when locking and becomes larger to loosen the pipe when loosening.
