Bracket for surface mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional L-shaped mounting brackets often fail to securely attach to wall support columns, leading to reduced load capacity due to misalignment issues, necessitating the use of weaker wall anchors which can result in the bracket pulling away from the wall under load.
Innovation Solution
The design of a two-piece or single-piece bracket with horizontally spaced mounting holes located above the arm, providing increased load capacity by utilizing both the wall column and wall covering material for attachment, and featuring cradles and adjustable arms to securely hold rods or other items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional L-shaped brackets are mounted to the wall using vertically aligned fasteners below the horizontal leg, then the bracket can be easily installed, but the load capacity is reduced and the bracket may pull away from the wall under load
Solution Approach 1:
The bracket is divided into a vertical leg and a horizontal leg that are not collinear, creating separate mounting and support functions. The vertical leg contains mounting holes for fastener attachment to the wall column, while the horizontal leg provides the cantilevered support surface, separating the mounting function from the load-bearing function to optimize both installation and strength.
Solution Approach 2:
The bracket transitions from a traditional vertical-horizontal L-shape to a configuration where the vertical leg is offset from the wall surface. This dimensional change allows the mounting holes to be positioned on the vertical leg for secure column attachment while the horizontal leg extends outward to provide support, creating a three-dimensional mounting structure that optimizes both installation ease and load capacity.
2Adaptability or versatility
If brackets are mounted away from wall support columns to center support structures on the wall, then the desired location alignment is achieved, but the attachment strength is reduced requiring weaker wall anchors
Solution Approach 1:
The bracket design separates the mounting function (vertical leg with holes for fastener attachment to wall column) from the support function (horizontal leg providing cantilevered surface). This segmentation allows the vertical leg to be precisely positioned at the wall column location for strong attachment, while the horizontal leg can be oriented to center support structures on the wall, achieving both strong attachment and location flexibility.
3Ease of operation
If the vertical leg is affixed to the wall with fasteners aligned vertically below the horizontal leg, then the mounting is simple, but the bracket pulls away from the wall under load
Solution Approach 1:
The bracket is segmented into a vertical leg for mounting and a horizontal leg for support. The vertical leg contains mounting holes positioned to align with wall columns, allowing simple vertical fastener installation. The horizontal leg extends perpendicular to the vertical leg to provide the cantilevered support surface, separating mounting simplicity from load-bearing reliability.
Solution Approach 2:
The bracket configuration moves the horizontal support leg to a different dimensional plane relative to the vertical mounting leg, creating an offset L-shape where the vertical leg is affixed to the wall column and the horizontal leg provides outward support. This dimensional arrangement ensures that mounting holes are positioned for simple vertical fastener attachment while the horizontal leg effectively resists pulling away under load.

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.
