Beveled Wall-Mount Bracket for Higher Facade Panel Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal brackets for securing facade panels on building walls face issues with anchor plate bending under heavy loads, leading to lever forces that weaken and potentially loosen mounting screws.
Innovation Solution
A mounting bracket with an anchor plate featuring a bevel along its upper and/or lower edge, near the mounting holes, which prevents lever action when the anchor plate bends, combined with a support plate and optional reinforcement struts or clamping features, ensuring consistent screw pressure and enhanced load-bearing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the wall thickness of the bracket is reduced to decrease weight and cost, then the load-bearing capacity and structural integrity deteriorate under heavy tractile loads
Solution Approach 1:
The patent applies local quality by creating a bevel at the upper edge of the anchor plate that concentrates material density and structural reinforcement precisely where the bending moment is highest (near the mounting hole), while keeping the rest of the bracket wall thickness minimal. This localized geometric modification provides enhanced strength at the critical stress point without increasing the overall weight of the bracket.
2Strength
If the anchor plate is allowed to bend under heavy loads, then the lever forces created by the overhanging end loosen or tear out the mounting screws
Solution Approach 1:
The bevel creates a preliminary counteracting force through its geometric configuration. When the anchor plate bends under load, the beveled surface contacts the wall at an angle that generates a counter-moment opposing the bending tendency, thereby preventing the overhanging end from creating lever forces that would loosen the mounting screws.
Solution Approach 2:
The patent converts the harmful bending deformation into a beneficial self-aligning mechanism. The controlled bending of the anchor plate causes the beveled edge to contact the wall surface, transforming the harmful lever effect into a beneficial self-centering action that maintains screw engagement and even improves load distribution.
3Reliability
If the bevel is positioned to prevent lever forces, then the mounting hole placement and anchor plate geometry are constrained
Solution Approach 1:
The bevel parameters (angle, length, position) are optimized to provide the necessary counter-moment while maintaining compatibility with standard mounting hole configurations. By carefully selecting the bevel geometry parameters, the patent achieves reliable screw holdfast without requiring non-standard or overly complex anchor plate designs.

AI summary
A mounting bracket for securing to an upright wall has an anchor plate formed with an upper horizontally throughgoing mounting hole and having a back face engageable with the wall, and a support plate fixed to and extending horizontally from the anchor plate below the upper mounting hole. The back face is formed between the upper mounting hole and an upper edge of the anchor plate with a bevel having a bevel face extending upward away from the wall.
