Cloth-Tensioning System With Adjustable Corner Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tensioning systems for cloths, such as those used for terrace coverings, face issues like irregular corner finishes, limited accessibility for cloth removal or replacement, and non-adjustable tensioning, which can lead to creasing and instability in wind conditions.
Innovation Solution
A tensioning system comprising a frame with lateral and corner-tensioning systems, where tensioning profiles and corner plates are adjustable, allowing for lateral and diagonal tensioning, and are accessible from the rear for easy adjustment and removal, eliminating the need for temporary connecting means like silicone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a frame with slidable profiles is used for lateral tensioning, then the cloth can be tensioned laterally, but the profiles become detached from each other and no regular finish of the corners is possible
Solution Approach 1:
The tensioning system is divided into separate lateral tensioning components and corner tensioning components. Each corner has its own corner plate that can be independently adjusted, allowing precise corner finishing while maintaining lateral tensioning capability through the frame structure.
2Ease of operation
If a canvas with slats screwed onto profiles is used, then the cloth can be tensioned on the profile, but the tensioning system is only accessible from the side and removal or replacement of the cloth is impossible
Solution Approach 1:
The corner plates and tensioning elements are designed with adjustable and removable features. The corner plates can be detached from the frame profiles, and the cloth can be released from the tensioning system, enabling easy maintenance and replacement operations.
3Force
If springs are used for tensioning between the profile and the cloth, then tensioning is achieved, but the tension depends on spring force which does not allow for adjustment in situ and tensioning has to be performed beforehand
Solution Approach 1:
The corner plates are designed with adjustable positioning mechanisms that allow the tensioning force to be modified in situ. The corner plates can be moved to different positions along the frame profiles, enabling tension adjustment without replacing the entire system or performing preliminary tensioning.
Solution Approach 2:
The system allows changing the tensioning parameter by adjusting the position of the corner plates and their attachment to the frame profiles. This enables in-situ modification of the tensioning force to adapt to different operational requirements.
4Force
If springs are used for tensioning, then tensioning is achieved, but it is difficult to achieve tension at the position of the corners and a connecting means such as silicone has to be used which is not sufficiently compact
Solution Approach 1:
The corner tensioning function is merged into the corner plate structure itself. The corner plates directly engage with both frame profiles and the cloth, integrating the corner tensioning mechanism into a single compact component that eliminates the need for separate connecting means like silicone.
