Wall Bracket Fold for Insulation Span Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Holding devices for attaching panel-shaped wall or ceiling cladding elements to structural substructures face challenges in mechanical stability, particularly when dealing with heavy facade elements like natural stone or glass, due to the need to span insulation layers, which increases static requirements without sufficient material support.
Innovation Solution
A wall bracket with a fold on its second leg, made from the same material, increases mechanical stability by stiffening the leg without adding extra material, allowing it to withstand loads better and maintain structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the projection of the wall bracket is increased to span insulation layers, then the load-bearing capacity is improved, but the mechanical stability deteriorates due to increased bending and buckling risks
Solution Approach 1:
The patent applies curvature by introducing bends at 45-degree angles in the second leg of the wall bracket. These bends create a curved geometry that transforms the straight leg into a stepped configuration, increasing the moment of inertia and thus improving mechanical stability while maintaining the required projection length for spanning insulation layers
2Stability of the object's composition
If additional material is added to increase the cross-section of the wall bracket, then the mechanical stability is improved, but the manufacturing cost and material usage increase
Solution Approach 1:
Instead of increasing material quantity, the patent uses geometric curvature through bends to achieve the same stabilizing effect. The bends create a stepped profile that increases structural rigidity without requiring additional material, thus resolving the contradiction between mechanical stability and material usage
3Ease of manufacture
If the wall bracket is designed with a simple straight geometry, then the manufacturing simplicity is maintained, but the load-bearing capacity deteriorates under heavy facade elements
Solution Approach 1:
The patent introduces bends at specific 45-degree angles to create a stepped geometry in the second leg. This curved configuration can be easily manufactured using standard bending processes and remains compatible with conventional production methods, thus maintaining manufacturing simplicity while significantly improving load-bearing capacity for heavy facade elements
