Quick-Fixing Rail Clip for Twist-Proof Single-Rod Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-fastening elements for guide rails in lattice-like side parts require multiple rods for secure mounting, lacking effective protection against torsion and tilting, and often result in unintentional detachment.
Innovation Solution
A quick-action fastening element with a clamp-like holding section in its longitudinal and angled end areas, featuring a resilient latching tongue for secure attachment and prevention of unintentional detachment, allowing the guide rail to be fixed to a single horizontally extending rod while preventing rotation and longitudinal displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple rods are used for mounting guide rails, then secure mounting is achieved, but device complexity and mounting time increase
Solution Approach 1:
The quick-action fastening element is divided into two distinct clamp-like holding sections: a first holding section with a first clamp-like structure for engaging the rod's longitudinal extension area, and a second holding section with a second clamp-like structure for engaging the rod's angled end area. This segmentation allows each holding section to independently secure different portions of the rod, achieving reliable mounting while simplifying the overall structure by using a single integrated fastening element rather than multiple separate components.
2Ease of operation
If quick-action fastening elements are pushed onto rods with friction fit, then ease of installation is improved, but unintentional detachment occurs
Solution Approach 1:
The fastening element incorporates resilient elements (springs) that provide dynamic, elastic forces to the clamp-like structures. These resilient elements enable the fastening element to be easily pushed onto the rod with friction fit during installation, while simultaneously maintaining continuous elastic pressure that prevents unintentional detachment. The dynamic nature of the resilient elements allows the fastening element to adapt to slight variations in rod dimensions while maintaining secure engagement.
3Stability of the object's composition
If clamp-like holding sections partially encompass the rod, then protection against torsion and tilting is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The first and second clamp-like holding sections are designed with asymmetric geometries that naturally accommodate the rod's position and orientation. The clamp-like structures feature asymmetric engagement surfaces that provide inherent alignment guidance, reducing the need for high manufacturing precision. The asymmetric design ensures that the fastening element can only be installed in the correct orientation, automatically preventing torsion and tilting while tolerating reasonable variations in rod positioning.

Function Achieved in This Case
The solution provides secure, twist-proof, and tilt-proof mounting of guide rails on a single rod, with a friction fit and resilient locking mechanism ensuring stability and ease of deliberate detachment for maintenance.
Implementation Method 1
equipping one leg of the holding section enclosing the rod in its longitudinal extension area with a resilient latching tongue which rests against a region of the rod facing away from the guide rail
Implementation Method 2
the quick-action fastening element is pushed onto the rod in a clamping manner, that is to say largely with a friction fit
