Profiled Rail Tilting Prevention via Opening Width Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profiled rails face issues during attachment to structural components, as the distance between opposite wall sections is often greater than the opening width, leading to tilting and increased mounting costs due to mismatched opening widths, which can result in the attachment element engaging edges or requiring additional measures to prevent tilting under load.
Innovation Solution
A profiled rail design where the minimal distance between opposite wall sections matches the opening width, featuring elongate openings and collars that guide the attachment element, preventing tilting and enhancing flexural and torsional strength, with the option of one or both openings being elongate and aligned with the rail's longitudinal axis, and collars providing additional support.

1Length of moving object
If the distance between opposite wall sections is greater than the opening width, then the profiled rail can accommodate larger attachment elements, but the attachment element may engage the edge of the opposite opening causing tilting and increased mounting costs
Solution Approach 1:
The patent changes the geometric parameters by making the opening width equal to the distance between opposite wall sections. This precise parameter matching ensures that the attachment element passes through without engaging the edges, eliminating tilting while accommodating sufficiently large attachment elements.
2Device complexity
If the opening width is smaller than the distance between opposite wall sections, then the profiled rail structure is more compact, but additional measures are required to prevent tilting under load
Solution Approach 1:
The patent optimizes the opening width parameter to match the distance between opposite wall sections exactly. This eliminates the need for additional anti-tilting measures, reducing both structural complexity and manufacturing costs while maintaining compact dimensions.
3Adaptability or versatility
If different opening widths are used for opposite openings, then the profiled rail can accommodate various attachment elements, but tilting occurs under load requiring expensive prevention measures
Solution Approach 1:
The patent standardizes the opening width parameter across opposite openings to be equal to the distance between opposite wall sections. This uniform parameter design provides sufficient versatility for different attachment elements while ensuring symmetrical load distribution that prevents tilting without expensive reinforcement.

AI summary
A profiled rail has two opposite side walls (13) at least one connection wall (16) for connecting the side walls (13), first and second openings (17, 37; 27, 47) for passing therethrough a connection element (6) and having, respectively, first and second opening widths (B; F; C; G) measured in a direction perpendicular to a longitudinal profile axis (12) of the profiled rail, with a minimal distance (A; E) between the opposite wall sections (14; 34) of the side walls (13; 33), which is measured in the direction perpendicular to the longitudinal profile axis (12) of the profiled rail, at most corresponding to the opening width of (B; F; C; G) the first and second openings (17, 37; 27; 47).
