Surface-Mount Bracket with Horizontal Hole Spacing for Load Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional L-shaped mounting brackets for surface mounting often fail to provide sufficient load capacity due to their design, which limits their ability to attach directly to wall support columns, necessitating the use of wall anchors that offer weaker attachment.
Innovation Solution
A two-piece bracket design featuring a mounting bracket with horizontally spaced mounting holes located at the top and above the arm, which increases the load capacity by distributing the weight more effectively across the wall and support structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional L-shaped mounting brackets are used, then the structure is simple and easy to manufacture, but the load capacity is insufficient and wall anchors are required
Solution Approach 1:
The bracket is divided into two distinct pieces: a mounting bracket that attaches to the wall and an arm that extends outward. This segmentation allows each component to be optimized for its specific function, with the mounting bracket designed to maximize attachment strength to wall support columns while the arm provides the necessary support structure.
Solution Approach 2:
The mounting holes are positioned at the top of the mounting bracket rather than vertically aligned below the arm. This dimensional repositioning changes the attachment geometry to better distribute loads and engage with wall support columns, thereby increasing load capacity without significantly complicating the overall structure.
2Strength
If brackets are mounted to wall support columns, then load capacity increases, but the mounting location is restricted and installation becomes more difficult
Solution Approach 1:
The mounting bracket is designed with pre-positioned mounting holes at the top, oriented to align with typical wall support column locations. This preliminary design consideration allows installers to more easily locate and attach the bracket to wall support columns during installation, reducing the difficulty despite the requirement to find suitable mounting locations.
3Adaptability or versatility
If wall anchors are used instead of direct column attachment, then mounting flexibility increases, but the attachment strength decreases significantly
Solution Approach 1:
The mounting bracket is designed with specific local features at the mounting holes, including positioning and orientation optimized for engagement with wall support columns. This local quality enhancement at the attachment points maximizes strength where it is most needed, while the rest of the bracket maintains flexibility for various installations.

AI summary
A bracket for mounting objects to a wall includes a base defining mounting holes for fasteners. An arm extends from the base and has a top, a bottom and a maximum width at the interconnection with the base. The mounting holes includes at least two that are spaced from another by a distance greater than a maximum width of the arm so that one of the mounting holes is outside the arm on one side of the arm and another of the mounting holes is outside the arm on the other side of the arm. At least a portion of the mounting holes is located above the top of the arm.
