Vehicle Sheet Mounting System with Adjustable Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mounting systems for tensioned sheets on vehicles lack an efficient and secure method to maintain sheet signage in tension, particularly on vehicle sides, where the existing systems are not optimized for consistent and adjustable tensioning.
Innovation Solution
A mounting system utilizing elongate supports integrated with vehicle rub rails and frame members, featuring extruded aluminum components with undercut channels and flanges, allows for secure engagement and tensioning of sheet edges through a combination of fixed mortises and pinch rollers, enabling adjustable and consistent tensioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current mounting systems are used for tensioned sheets on vehicles, then the sheet can be mounted, but the sheet cannot be maintained in consistent and adjustable tension
Solution Approach 1:
The mounting system incorporates adjustable tensioning mechanisms that allow the sheet to be dynamically tensioned to different levels. The frame members include adjustable components that enable the sheet tension to be modified after installation, transforming a static mounting system into a dynamic one that can adapt to different tension requirements while maintaining reliable sheet attachment.
Solution Approach 2:
The system allows for changing the tension parameter of the sheet through adjustable mounting components. The frame members are designed with adjustment capabilities that enable modification of physical parameters such as tension force and positioning, allowing the same mounting system to maintain sheets at various tension levels according to specific application requirements.
2Reliability
If integrated support structures are used, then the mounting is secure, but the system complexity increases
Solution Approach 1:
The frame members are designed to perform multiple functions: they provide structural support for the sheet, serve as mounting points for tensioning mechanisms, and integrate with vehicle body structures. This multi-functionality reduces the need for separate components, thereby maintaining mounting security while minimizing overall system complexity.
Solution Approach 2:
The mounting system merges the support structure with the tensioning mechanism into an integrated assembly. The frame members combine structural support functions with attachment and tensioning functions, reducing the number of discrete parts and simplifying the overall system while maintaining secure sheet mounting.

AI summary
A mounting system for a sheet on a vehicle includes two elongate rub rails with undercut channels to receive the sheet and tensioning components. The upper rub rail is engaged with one of opposed edges of the sheet. An elongate engagement is engaged with the other opposed edge of the sheet and includes one frame rail and an engagement surface both facing the upper rub rail. An elongate retainer includes a bead engaged with the lower rub rail, another frame rail and parallel retainer surfaces, the second frame rail and the parallel retainer surfaces facing away from the upper rub rail. The engagement surface is movable laterally of the parallel retainer surfaces to be positioned in interlocking engagement with any one of the parallel retainer surfaces to tension the sheet.
