Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe clamps with U-shaped grooves suffer from deformation and insufficient fixing force due to inadequate contact area between the clamp and the pipe, especially when dealing with pipes of varying diameters.
Innovation Solution
A pipe clamp structure incorporating a first U-shaped groove, a first movable member with a movable U-shaped groove, and a rotating member, which allows the movable member to be pushed 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 (periphery edge of cover), 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 a single-point contact into distributed multi-point contact. This segmentation allows the locking force to be distributed across multiple locations, preventing excessive stress concentration and deformation at any single point while maintaining structural simplicity.
2Ease of manufacture
If the arc of the U-shaped groove is inconsistent with the pipe, then the structure is simple to manufacture, but the contact area is reduced resulting in insufficient fixing force
Solution Approach 1:
The U-shaped groove incorporates a movable member that can dynamically adjust its position and orientation to match the pipe's curvature. This dynamic adjustment capability allows the groove to adapt to different pipe diameters and shapes, maximizing contact area and fixing force while maintaining ease of manufacture through a standardized base structure.
3Device complexity
If no outward supporting structure is added inside the U-shaped groove, then the device complexity is low, but the groove deforms inward during cover rotation
Solution Approach 1:
Outward supporting structures are pre-installed inside the U-shaped groove to provide preventive support against inward deformation. These supporting structures act as cushioning elements that counteract the deformation forces generated during cover rotation, maintaining groove shape stability before deformation can occur.
4Area of stationary object
If a circular disk piece with arc surface is added, then the contact area with pipe is increased, but the arc opening size limits the pipe diameter range
Solution Approach 1:
The circular disk piece is designed with a universal arc surface that can accommodate multiple pipe diameters. The arc opening is sized to provide sufficient contact area for various pipe sizes, and the movable member can adjust its position to optimize contact for different diameters, making the clamp versatile across a wide range of pipe sizes while maintaining large contact area.
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 solution effectively addresses the issues of 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
By locking tight the first thread and the second thread, the first bottom portion pushes the first movable member toward the first U-shaped groove, and the first clamping space is reduced to clamp tight the pipe
Implementation Method 2
the first U-shaped groove and the first movable U-shaped groove clamp tight the pipe

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.
