Rotating Wall-Mount Tube Holder with Elastic Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for tubes, such as fluid conduits and cable sheaths, require significant force to press-fit tubes into clamps, risking damage and necessitate simultaneous force application across multiple devices, which is inefficient and potentially damaging, especially for flexible or corrugated tubes.
Innovation Solution
A holding device with a rotating first body that inserts the tube into a cradle without applying force to the tube, allowing easy installation and release, and accommodating tubes of varying diameters with flexible flanges and hook-shaped arms, enabling secure fixation without damaging the tube.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If force is applied to press-fit the tube into the clamp, then the tube is securely held, but the tube may become damaged
Solution Approach 1:
Instead of pushing the tube into the clamp, the clamp is rotated around the tube. The tube remains stationary while the clamp arms swing around and engage the tube from the front, eliminating the need to apply force to the tube itself.
Solution Approach 2:
The linear pressing motion is replaced by a rotational motion. The screw mechanism converts rotational motion into rotational movement of the clamp arms, which then engage the tube through their own elastic deformation rather than forcing the tube into position.
2Productivity
If force is applied to press-fit the tube into multiple clamps simultaneously, then all tubes are secured, but the operation becomes complex and inefficient
Solution Approach 1:
Each clamp is equipped with an independent screw mechanism that can be operated separately. This allows each clamp to be adjusted and engaged independently, eliminating the need to apply force to multiple clamps simultaneously while maintaining efficient installation.
3Reliability
If the clamp opening is made smaller to secure the tube, then the tube is held firmly, but the tube cannot be easily inserted
Solution Approach 1:
The clamp arms are made elastically flexible so that they can dynamically adapt during the engagement process. When the screw is rotated, the arms swing around and elastically deform to engage the tube, then maintain a firm grip once engaged.
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 solution allows for easy, damage-free fixation of tubes to a wall with reduced force requirements, enabling secure holding of tubes of different diameters and irregular surfaces, and simplifies the installation process by rotating the clamp mechanism, eliminating the need for simultaneous force application across multiple devices.
Implementation Method 1
A force must be applied on the tube against the arms of the clamp to cause elastic deformation of said arms, allowing the tube to be press-fitted into the clamp
Implementation Method 2
a screw with a threaded head, a main body in which the open clamp is formed and a nut which is placed in a hole of the main body and which is screwed on the threaded head of the screw

AI summary
The present invention relates to a holding device (1) which can be fixed to a wall for holding a tube and comprising a first body (6) forming an open clamp (4) and a second body (7) forming a through hole and a support surface. The first body (6) can rotate about an axis. The holding device (1) forms a cradle demarcating a free space corresponding to the tube and extending in a direction orthogonal to the axis. The cradle has a bottom and an open upper face (11) for inserting the tube. By means of rotation of the first body (6) about the axis, the opening of the open clamp (4) traverses the free space which was demarcated by the cradle before the rotation.
