Pipe Clamp With Foldable Link And Threaded Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipe clamps fail to securely clamp joints of varying pipe diameters and are prone to release due to external impacts, as they are not adaptable to different sizes and lack sufficient fastening mechanisms.
Innovation Solution
A pipe clamp design featuring hingedly coupled bodies, a link system with foldable links, and a fastening bar with threads and a nut, which allows for adjustable fitting and secure engagement through a threaded hole, preventing release from external impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pipe clamp is designed with a fixed size, then the structure is simple, but it cannot clamp pipes of various sizes
Solution Approach 1:
The link is designed to be foldable rather than fixed, allowing the clamp bodies to adjust their relative positions. This dynamic structure enables the pipe clamp to adapt to different pipe diameters by folding the link to appropriate angles, resolving the contradiction between fixed structure and size adaptability.
Solution Approach 2:
The foldable link design allows a single pipe clamp structure to serve multiple functions by accommodating pipes of various sizes. The same clamp can be adjusted to fit small, medium, and large diameter pipes through different folding configurations, achieving universality without requiring multiple specialized clamps.
2Reliability
If the fastening bar is prevented from rotation by an anti-rotation protrusion, then the fastening is improved, but the fastening bar is still released when external impact is applied
Solution Approach 1:
The fastening mechanism is segmented into multiple independent elements: the fastening bar with external thread, the threaded hole in the clamp body, and the nut. This segmentation creates a more robust fastening system where the threaded engagement provides mechanical interlocking that resists external impacts better than a simple anti-rotation protrusion.
Solution Approach 2:
The nut acts as an intermediary element between the fastening bar and the clamp body. By threading the fastening bar through the nut and into the threaded hole, the system creates a distributed fastening mechanism that better absorbs and distributes external impact forces, preventing release.
3Reliability
If the joint portion is small compared to the pipe clamp, then the clamp structure is simple, but the joint portion is not firmly clamped
Solution Approach 1:
The clamp bodies are designed with specific clamping surfaces and geometries that concentrate the clamping force precisely on the joint portion. The foldable link allows the clamp to conform to the actual size of the joint, ensuring that the clamping force is applied locally and effectively where needed, rather than being distributed over a large area.
4Reliability
If the joint portion is large compared to the pipe clamp, then the clamp can cover the joint, but the fastening bar is not firmly fastened to the fastening protrusion
Solution Approach 1:
The foldable link provides the necessary dynamic adjustment range to accommodate large distances between clamp bodies when clamping large diameter pipes. The link can be folded to extend the span between bodies while maintaining the threaded fastening mechanism's ability to provide firm fastening through the nut and threaded hole engagement.
