Adjustable Mounting Element for Tensioning Frames on Uneven Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tensioning frame systems face challenges in securely attaching to uneven substrates, such as profiled sheet metal, due to irregular surfaces, which can lead to wrinkling and distortion of canvas covers on trucks and trailers.
Innovation Solution
A mounting element with a frame-like fastening section that can be clipped onto a tensioning frame part, featuring adjustable support parts that can be shortened to accommodate substrate irregularities, and attached using adhesives or mechanical fasteners, ensuring a secure and even attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting methods (screws, rivets, adhesives) are used to attach tensioning frames to substrates, then the frame can be secured to flat surfaces, but the mounting becomes difficult and suboptimal on uneven substrates such as profiled sheet metal
Solution Approach 1:
The support parts of the mounting element are designed to be adjustable in length, allowing the mounting element to adapt dynamically to different substrate surfaces. The support parts can be shortened using a break-off tool to compensate for surface irregularities, ensuring optimal contact and attachment security on both flat and uneven substrates
Solution Approach 2:
The mounting element incorporates support parts with variable length parameters. By changing the length parameter of the support parts through selective shortening, the mounting element can accommodate different substrate conditions, transforming a fixed-parameter mounting solution into a variable-parameter one that adapts to surface irregularities
2Adaptability or versatility
If the support parts are made long to accommodate uneven surfaces, then adaptability improves, but the device complexity and weight increase
Solution Approach 1:
The mounting element is segmented into distinct functional parts: a frame-like fastening section for attaching to the tensioning frame, support parts for contacting the substrate, and a connecting structure. This segmentation allows each part to be optimized independently, with support parts that can be selectively shortened without affecting the overall structural integrity or adding unnecessary complexity
3Reliability
If multiple fastening methods (adhesive and mechanical fasteners) are used, then attachment reliability improves, but the ease of operation and installation time worsen
Solution Approach 1:
The mounting element is designed with multi-functionality, incorporating both adhesive application surfaces and mechanical fastening features (edge parts with undercut areas) into a single integrated component. This allows the same mounting element to be installed using either adhesive alone, mechanical fasteners alone, or both methods combined, providing installation flexibility without requiring multiple different mounting components
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 mounting element effectively secures tensioning frame parts to substrates, preventing distortion and wrinkling by distributing forces evenly and allowing for easy adaptation to uneven surfaces, thereby maintaining the visual integrity of canvas covers.
Implementation Method 1
The mounting element is attached by means of an adhesive and/or at least one mechanical fastening element to the substrate and to the frame part
Implementation Method 2
The clip-on connections can be easily formed by edge parts provided on the transverse webs, these parts being formed with undercut areas
