Slat Holder Guide Surface Prevents Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slat holders for commercial vehicle superstructures often cause jamming and tilting issues when inserting or removing planar slats due to the protruding rivet heads, which complicate horizontal alignment and lead to undesirable longitudinal movements during driving.
Innovation Solution
A guide surface is introduced between the side walls of the supporting shell, opposite the end face of the slat, ensuring the slat contacts this surface rather than the rivet heads, preventing jamming by dividing the guide surface into multiple partial surfaces that maintain uninterrupted guidance and full-width contact with the vehicle's profile support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slat holder uses rivet attachment with protruding rivet heads, then the supporting shell can be securely fastened to the profile support, but the slat ends get caught on the rivet heads causing jamming and tilting during insertion and removal
Solution Approach 1:
A guide surface is introduced as an intermediary element between the rivet heads and the slat end. This guide surface, formed by deforming the supporting shell material, acts as a mediator that guides the slat into proper alignment and prevents contact with the protruding rivet heads, thereby eliminating jamming while maintaining secure fastening
Solution Approach 2:
The guide surface is formed in advance on the supporting shell before slat insertion. By pre-shaping the material to create the guide surface, the system prepares the necessary alignment feature beforehand, ensuring that slats are guided correctly during insertion and preventing tilting before the slat even contacts the rivet heads
2Ease of operation
If the guide surface is formed by deforming the supporting shell material, then slat guidance is improved preventing jamming, but the contact area of the supporting shell on the profile support is reduced
Solution Approach 1:
The deformation to create the guide surface is applied locally at specific corners of the supporting shell, not across the entire structure. This localized deformation approach creates the necessary guidance function while preserving the overall contact area between the supporting shell and the profile support, maintaining structural stability

AI summary
A slat holder for commercial vehicle bodies is proposed, comprising an upwardly open support shell (5) that receives the end of a slat (6). The support shell consists of at least a base (10), side walls (11, 12) facing inwards and outwards, and a mounting wall opposite the end face of the slat, which is riveted or bolted to a vertical profile support (3) of the vehicle body. The screw or rivet passing through an opening in the mounting wall (13) bears against a support surface (17) on the inside of the mounting wall (13). To prevent the slat from tilting, especially at the protruding rivet heads, a guide surface (20) is proposed, arranged between the two side walls (11, 12) at the level of the rivet opening or higher. This guide surface faces the end face of the slat and projects towards it compared to the support surface (17).
