Pipe Clip With Curved Threaded Element For High Holding Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe clamps have limited holding force due to thin threaded elements, which restricts their ability to securely fasten heavier pipes, and often require significant force for assembly and closure, making them difficult to use effectively.
Innovation Solution
A pipe clamp design featuring a half-cylindrical or half-roller threaded element with a convex contour and a concave recess allows for a thicker threaded element with multiple turns, enabling high clamping forces and easy assembly through a smooth click closure mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a thin threaded element is used, then the device complexity is reduced and assembly is simpler, but the holding force and clamping capability are limited
Solution Approach 1:
The threaded element is designed with a curved, roller-like cross-section instead of a straight cylindrical shape. This curvature allows the element to pivot and roll during operation, enabling a thicker design with multiple thread turns that provides increased holding force while maintaining smooth operation through rolling motion rather than sliding friction.
2Strength
If a thicker threaded element with multiple threads is used, then the holding force increases, but the restoring element cannot effectively act upon it for click closure
Solution Approach 1:
The curved roller-like shape of the threaded element enables it to pivot smoothly on its axis when acted upon by the restoring element. This curvature allows the restoring element to effectively engage with the threaded element even when it is thicker, facilitating the click closure mechanism where the clamping screw automatically clicks into the pipe clamp fork upon closing.
Solution Approach 2:
The threaded element is designed to be dynamically pivotable and rollable rather than statically fixed. This dynamic capability allows the restoring element to effectively act upon the threaded element during the closing operation, enabling the automatic click closure function while accommodating the thicker design with multiple thread turns.
3Ease of operation
If significant force is applied during assembly, then the clamping screw can be pivoted against the spring clip, but the unfavorable lever ratios make handling difficult and prevent quick assembly
Solution Approach 1:
The curved roller-like threaded element reduces friction during pivoting by enabling rolling motion. This significantly reduces the force required to pivot the clamping screw against the spring clip during assembly, eliminating the unfavorable lever ratio problem and allowing quick, easy handling without requiring excessive closing force.

AI summary
The clip has a clip body comprising clamping flanges (6). A concave recess (12) is formed in one of the clamping flange supporting a thread element (9) or in a reset element (13) operating on the thread element. The thread element comprises a convex contour on a side, where the contour lies in the concave recess. A rotational movement of a clamping screw (8) during closing and/or opening the clip is connected with rotation and /or rolling of the thread element in the concave recess. The reset element is made of stainless steel or plastic.
