Web-Shaped Holding Part with Embossing for Pull-Out Guide Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for push elements on movable rails in pull-out guides face issues where high tensile forces can cause the web-shaped holding part to be torn out of the clamping mechanism, leading to loose connections, especially when the clamping elements dig into the material or make it difficult to lift the holding part vertically.
Innovation Solution
A fastening device with a web-shaped holding part featuring embossings, such as depressions or elevations, that provide an interfering edge to prevent tearing out, combined with a clamping mechanism using rolling elements that are supported on angled walls, ensuring a secure frictional hold even under high tensile forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the clamping elements are made to dig into the material of the web-shaped holding part to prevent tearing out, then the holding force is improved, but the ease of operation deteriorates because lifting the holding part vertically is prevented
Solution Approach 1:
The patent applies local quality by creating embossments only at specific locations on the web-shaped holding part where tensile forces are most likely to cause tearing. These localized embossed portions provide enhanced friction and mechanical interlocking precisely where needed, while leaving other areas smooth for easy insertion and release operations.
2Ease of manufacture
If the web-shaped holding part has a smooth surface design, then the ease of manufacture is improved, but the reliability deteriorates because the holding part can be easily torn out under high tensile forces
Solution Approach 1:
The embossed portions are created using simple stamping or embossing processes that add minimal manufacturing complexity. The local deformation of the material creates tear-resistant features without requiring additional components or complex manufacturing steps, thus maintaining ease of manufacture while significantly improving connection stability.
3Strength
If the clamping mechanism uses a bar-shaped retaining part, then the holding force is improved, but the reliability deteriorates because very high tensile forces can cause the retaining part to tear out of the receptacle
Solution Approach 1:
The patent transitions from a simple bar-shaped retaining part to a web-shaped holding part with three-dimensional embossed portions. These embossments add vertical dimension and surface complexity to the contact interface, creating multiple friction points and mechanical interlocking features that prevent tearing out in directions that a simple bar shape cannot resist.
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 embossings significantly increase holding forces and prevent the web-shaped holding part from being pulled out, maintaining a stable connection and preventing damage to the coating, while allowing for easy assembly and disassembly.
Implementation Method 1
a clamping mechanism with a receptacle on which at least one self-locking clamping element is provided, which is formed by a rolling element movably arranged in a housing and frictionally secures the web-shaped holding part inserted into the receptacle against withdrawal

AI summary
A fastening device for fixing a sliding element on a displaceable rail (2, 22) of a pull-out guide (20) comprises a crosspiece-like retaining part (6, 24) and a clamping mechanism with a mount (7, 33), the clamping mechanism being provided with at least one self-locking clamping element (10, 30), by means of which the crosspiece-like retaining part (6, 24) fitted into the mount (7, 33) is secured in a friction-fitting manner against being pulled out, wherein the crosspiece-like retaining part (6, 24) has formed on it at least one stamped formation (6, 25), against which the clamping element (10, 30) lies. This makes it possible for the crosspiece-like retaining part (6, 24) to be fixed in a stable manner on the mount and to be easily removed.
