Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generic profile elements used in sun protection devices often experience undesirable deflections due to weight, leading to aesthetic and functional issues, particularly with large spans and heavy devices, and existing solutions like tension cables or rods are complex and costly to implement.
Innovation Solution
A profile element featuring a compression bar that runs outside the neutral bending fiber, with adjustable end pieces to clamp the pressure rod, allowing for compensatory bending forces that counteract weight-induced deflections without the complexity of tension cables, enabling flexible adjustment to maintain vertical alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a tension cable or tension element is used to compensate for deflection, then deflection compensation is achieved, but the production cost increases significantly and the device complexity increases
Solution Approach 1:
Instead of using a tension cable that runs below the neutral bending fiber to compensate for deflection, the patent inverts the approach by using a compression bar that runs above the neutral bending fiber. This compression bar applies a bending moment in the opposite direction to the deflection caused by the sun protection device weight, achieving deflection compensation without the complexity of tension cable routing and support structures.
Solution Approach 2:
The patent extracts the essential function of deflection compensation from the complex tension cable system and implements it through a simpler compression bar mechanism. By removing the need for tension cables, pulleys, and complex support structures, the solution achieves the same deflection compensation effect with significantly reduced device complexity and production cost.
2Stability of the object's composition
If a tension cable is used for deflection compensation, then deflection can be compensated, but the solution cannot be used with profile elements that have functional sections on the underside
Solution Approach 1:
The patent inverts the location of the deflection compensation mechanism from below the neutral bending fiber (where tension cables would interfere with functional sections) to above the neutral bending fiber. The compression bar is positioned in the upper region of the profile element, away from functional sections on the underside, allowing both deflection compensation and functional profile sections to coexist without interference.
3Area of stationary object
If the span between wall brackets is increased, then the coverage area is improved, but deflection increases to an impermissible extent
Solution Approach 1:
The compression bar acts as a mechanical counterweight system that generates an upward bending moment to counterbalance the downward deflection caused by the weight of the sun protection device. By adjusting the compression bar's position and precompression force, the system can compensate for deflection even over large spans, allowing increased coverage area without excessive deflection.
Solution Approach 2:
The patent utilizes parameter changes in the compression bar's precompression force and position to dynamically adjust the deflection compensation. By varying these parameters, the system can adapt to different span lengths and device weights, maintaining acceptable deflection levels across a range of coverage areas.
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 solution effectively compensates for deflections caused by weight, ensuring the profile element remains vertically aligned and functional, even with heavy sun protection devices, while allowing for design flexibility and reduced production costs.
Implementation Method 1
The forces acting on the end pieces in turn result in a bending load on the profile element. This bending load caused by the compression bar causes a correspondingly proportional bending deformation of the profile element.
Implementation Method 2
a compression bar (06, 16, 25) is provided in the profile element (01, 14), which runs at least in sections outside the neutral bending fiber of the profile element (01, 14)
Implementation Method 3
Pressure is exerted on the compression bar (06, 16, 25) due to the difference in length. Because of its rigidity or because of the corresponding support of the compression bar (06, 16, 25) in the profile element (01, 14), it is ensured that the compression bar (06, 16, 25) itself does not bulge significantly under the pressure.
