Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tensioning devices for materials like plastic sheets and textiles often result in wrinkled or uneven surfaces due to insufficient tension, which can be aesthetically unpleasing and prone to loss of tension over time.
Innovation Solution
A tensioning device comprising a support profile and a pivoting tensioning element that increases the distance between the element to be tensioned and the tensioning element, allowing for efficient tensioning through a simple movement and maintaining tension over time, with optional mechanical assistance for high force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional tensioning devices are used, then tensioning can be applied, but the surface becomes wrinkled or uneven due to insufficient tension
Solution Approach 1:
The tensioning element is designed to pivot between a first position (non-tensioning) and a second position (tensioning), transforming a static structure into a dynamic one. This allows the system to adapt its tensioning force by changing the angular position of the element, enabling precise control over the applied force to achieve smooth surfaces without excessive tension.
Solution Approach 2:
The invention changes the geometric parameter of the distance between the support profile and the tensioning element by pivoting the tensioning element. This parameter change allows continuous adjustment of tensioning force, enabling the system to achieve the optimal balance between sufficient tension for surface smoothness and controlled force to prevent material damage.
2Manufacturing precision
If great tension is applied to eliminate wrinkles, then surface smoothness improves, but the tensioning becomes undone after prolonged use
Solution Approach 1:
The pivoting mechanism allows the tensioning element to dynamically adjust to material relaxation over time. As the material settles, the element can be repositioned to maintain optimal tension, preventing the tensioning from becoming undone while avoiding excessive initial tension that would cause surface defects.
Solution Approach 2:
The system enables monitoring and adjustment of tensioning force over time through the pivoting mechanism. Users can observe surface conditions and adjust the element's position to maintain proper tension, creating a feedback loop that ensures long-term reliability and prevents tension loss.
3Device complexity
If a simple tensioning mechanism is used, then device complexity is reduced, but the ability to maintain tension over time is compromised
Solution Approach 1:
The single pivoting element provides a simple yet effective dynamic mechanism that enables tension adjustment without complex systems. The pivot joint allows the element to move between positions, providing tension maintenance capability while keeping the overall device structure simple and easy to manufacture.
4Stability of the object's composition
If the tensioning element is firmly fixed, then structural stability is improved, but the ability to adjust tension is lost
Solution Approach 1:
The tensioning element is designed with a pivot connection that provides rotational freedom while maintaining structural integrity. This dynamic connection allows the element to adjust its angular position for tension control while remaining firmly attached to the support profile, achieving both stability and adaptability simultaneously.

AI summary
The object of this invention is a tensioning device which can be used for tensioning, for example, plastic sheets, textile materials (3) and those that can be tensioned on a support structure so that the laminar element is left free of wrinkles or undulations. Another object of this invention is a panel which comprises said tensioning device and the assembly method thereof. The device object of the invention comprises at least a profile (1) intended to support the element (3) to be tensioned and a tensioning element (2) intended to be joined to the end area of the element to be tensioned. The tensioning element, in its operative position, is disposed joined to one of the faces (1.2) of the support profile in a pivoting manner so that by means of the pivoting thereof the element to be tensioned changes between a non-tensioned position and a tensioned position.
