Embedded Anchor with Curved Bonding Leg for Panel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-installed undercut anchors have limited pull-off strength due to small point load distribution, necessitating a solution that enhances structural bonding for attaching panels to building structures.
Innovation Solution
The design of an embedded anchor with a chassis and symmetrical bonding legs, featuring a proximal, curved intermediate, and distal region with notches, providing a broader surface area for structural bonding, which is easy and economical to manufacture, using materials like metal or plastic, and can be embedded in panels during concrete curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional post-installed undercut anchors are used, then installation is simple, but pull-off strength is limited due to small point load distribution
Solution Approach 1:
The bonding leg transitions from a simple linear form to a three-dimensional configuration with proximal, curved intermediate, and distal regions. This dimensional transformation allows the anchor to distribute loads across multiple spatial dimensions, increasing the effective bonding surface area and improving pull-off strength by engaging more concrete volume.
Solution Approach 2:
The curved intermediate bonding leg region introduces curvature to the anchor design, allowing the bonding surface to conform better to the concrete substrate. This curvature increases the contact area between the anchor and concrete, distributing stresses more evenly and enhancing bond strength compared to straight-linear configurations.
2Strength
If a broader distributed embed is used to improve pull-off strength, then structural bonding is enhanced, but device complexity increases
Solution Approach 1:
The bonding leg is segmented into distinct functional regions (proximal, curved intermediate, and distal regions), each serving a specific purpose in load distribution and bonding. This segmentation allows for optimized performance in each region while maintaining manufacturability through standardized forming processes.
Solution Approach 2:
The anchor design utilizes parameter changes in the bonding leg geometry, specifically transitioning through different curvature radii and cross-sectional dimensions along its length. These parameter variations are achieved through controlled forming processes that modify the material flow during manufacturing, creating complex geometries from simpler starting forms.

AI summary
Improved designs for embedded anchors that may be utilized to attach panels to other structures are described. An anchor includes a chassis and a leg. The chassis defines a mounting plate with a top surface and a downturned edge region projecting from the mounting plate in a direction substantially normal to the top surface. The bonding leg projects from the downturned edge region and is narrower than the downturned edge region. The bonding leg defines a proximal bonding leg region projecting from the downturned edge region in a direction normal to the top surface that transitions through a curved intermediate bonding leg region into a distal bonding leg region projecting from the curved intermediate bonding leg region in a direction parallel to the top surface. These anchors are easy and economical to manufacturer, and also provide a strong structural bond with panels due to the anchors' unique designs.
