Rail Fixing System with Aligned Actuation Device to Prevent Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail fixing systems often experience jamming issues with their common actuation devices and fail to reliably ensure necessary retention forces, particularly when coupling multiple systems to a profile rail.
Innovation Solution
A rail fixing system with a shared actuation device connected to positive-locking connection elements and supported by a resilient element, ensuring that these elements are aligned along a straight line for effective force transmission, preventing tilting and enhancing retention forces through a stable positive-locking connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common actuation device is used for both rail fixing arrangement and system coupling arrangement, then device complexity is reduced, but reliability deteriorates due to jamming issues and inability to ensure retention forces
Solution Approach 1:
The patent divides the common actuation device into two independent actuation devices - one dedicated to the rail fixing arrangement and another to the system coupling arrangement. This segmentation eliminates the jamming issues caused by the common device while maintaining operational simplicity through standardized components.
2Ease of manufacture
If positive-locking connection elements are not aligned along the resilient element's effective direction, then manufacturing is easier, but reliability deteriorates due to tilting and reduced retention forces
Solution Approach 1:
The patent employs asymmetric positioning of the positive-locking connection elements relative to the actuation device, while maintaining their alignment along the resilient element's effective direction. This asymmetric design facilitates easier manufacturing and assembly while ensuring the critical alignment for reliable retention forces is achieved.
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 provides a reliable and stable connection that prevents jamming and ensures higher retention forces, allowing for secure fixing and coupling of multiple rail fixing systems to a profile rail, preventing uncontrolled displacement or detachment.
Implementation Method 1
The actuation device is supported on a resilient element and the first positive-locking connection element, the second positive-locking connection element, and the resilient element are arranged along a straight line that extends in an effective direction of the resilient element.

AI summary
A rail fixing system comprises a rail fixing arrangement adapted to fix the rail fixing system to a profile rail, a system coupling arrangement adapted to fix the rail fixing system to another rail fixing system disposed adjacent to the rail fixing system on the profile rail, and an actuation device common to the rail fixing arrangement and the system coupling arrangement. The actuation device is connected to a first positive-locking connection element of the rail fixing arrangement and a second positive-locking connection element of the system coupling arrangement. The actuation device is supported on a resilient element and the first positive-locking connection element, the second positive-locking connection element, and the resilient element are arranged along a straight line that extends in an effective direction of the resilient element.
