Sliding Fastener Rail for Flexible Commercial Vehicle Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for commercial vehicle superstructures require varying sheet metal profiles and additional fasteners, leading to increased manufacturing and storage costs due to the need for custom-made components and limited positioning flexibility.
Innovation Solution
A one-piece, elongated sheet metal profile with a longitudinal recess and sliding connecting elements that can be positively engaged and positioned at any desired location, allowing for flexible attachment of components without the need for multiple profile lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If varying sheet metal profiles are used for different vehicle lengths and attachment positions, then attachment positioning flexibility is improved, but manufacturing complexity and storage costs increase
Solution Approach 1:
A single universal sheet metal profile design is used for all vehicle lengths and attachment positions. The profile includes a longitudinal recess that can accommodate connecting elements at any position along its length, eliminating the need for multiple customized profiles while maintaining full positioning flexibility for attachments.
2Manufacturing precision
If custom-made sheet metal profiles are produced for specific vehicle dimensions, then attachment positioning precision is improved, but manufacturing costs and production time increase
Solution Approach 1:
The sheet metal profile is pre-engineered with a longitudinal recess that extends along its entire length, allowing connecting elements to be positioned at any desired location without requiring custom manufacturing. This preliminary design enables rapid adaptation to different vehicle dimensions while maintaining precise attachment positioning.
3Adaptability or versatility
If multiple profile lengths are stocked to accommodate different vehicle sizes, then adaptability to various vehicle dimensions is improved, but inventory costs and storage requirements increase
Solution Approach 1:
Instead of maintaining inventory of multiple profile lengths, a single universal profile design is used that can be cut to any required length. The longitudinal recess and connecting element system remains functional regardless of the final profile length, eliminating the need to stock multiple variants while maintaining full adaptability.
4Adaptability or versatility
If additional fasteners are added for customer-specific attachments, then attachment versatility is improved, but device complexity and assembly time increase
Solution Approach 1:
The sheet metal profile integrates a longitudinal recess that serves as a built-in mounting system for all attachments. This unified approach eliminates the need for separate fasteners for different attachment types and positions, as the recess accommodates connecting elements that can secure various attachments along the entire profile length.

AI summary
The invention relates to a fastening system for attaching components to a superstructure (1) of a commercial vehicle, comprising an elongated, one-piece, uniform sheet metal profile (3) with a recess (5) extending in the longitudinal direction and at least one connecting element (4) that can be positively engaged in the recess (5) towards an opening (6) of the recess (5) and is displaceable in the longitudinal direction. This allows for any desired positioning of attachment components and variability for different sizes, particularly different lengths, because profiles of any length can be used. This reduces production and storage costs.
