Thin Brick Support Panel Mechanical Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thin brick support systems rely heavily on adhesive for initial placement and retention, which can be costly and require precise application, and often include complex profiles for engaging grooves or recesses, making installation complex and dependent on adhesive strength.
Innovation Solution
A steel support sheet with shallow channels or indentations and acute angle top edges that engage diagonally upward protrusions, allowing torque retention of thin bricks without a bottom support ledge, using the compression strength of the panel and mortar for secure placement, and optionally employing low-cost adhesives for installation assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used for initial placement and retention of thin brick, then the brick can be held in place until mortar sets, but the system becomes dependent on adhesive strength and requires precise application which increases cost and complexity
Solution Approach 1:
The patent replaces the chemical adhesive system with a mechanical retention system. The support panel features ledges and engagement structures that mechanically hold the thin brick in place through friction and physical interlocking, eliminating dependence on adhesive tensile strength while simplifying the installation process.
Solution Approach 2:
The support panel's ledge structure allows the thin brick to self-retain through its own weight and friction against the ledge. The system uses the brick's own characteristics (weight, dimensions) to achieve retention without requiring external adhesive application, making the system self-sufficient.
2Reliability
If complex profiles with grooves or recesses are used for engaging thin brick, then mechanical retention can be achieved, but the panel design becomes more complex and installation becomes more difficult
Solution Approach 1:
The support panel is divided into multiple discrete ledges positioned at different locations (top, bottom, and intermediate positions). Each ledge provides independent mechanical retention, allowing the system to achieve reliable retention through simple, repetitive structural elements rather than complex integrated profiles.
Solution Approach 2:
Instead of creating complex grooves or recesses in the panel to engage the brick, the patent uses protruding ledges that the brick sits upon. This inverts the engagement approach from negative space (grooves) to positive space (protrusions), simplifying both manufacturing and installation.
3Ease of operation
If adhesive is used for thin brick installation, then initial placement is possible, but the cost increases and repositioning becomes difficult once adhesive sets
Solution Approach 1:
The patent replaces the adhesive-based retention system with a mechanical ledge system. The ledges provide friction-based retention that allows the brick to be positioned and adjusted before final mortar placement, eliminating the need for adhesive and the associated cost and repositioning limitations.

AI summary
A support panel for thin brick, comprising a metal sheet, an array of groove retaining tabs having first tab edges, said first tab edges protruding from said sheet having at an upward angle of less than about 45 degrees, for a distance of less than about one quarter inch, and an array of mortar lock tabs having second tab edges, said second tab edges protruding from said sheet at a downward angle of greater than about 45 degrees, said array of mortar lock tabs being offset vertically from said array of groove retaining tabs, wherein, said array of groove retaining tabs are adapted to engage shallow dovetail grooves formed in the rear of thin bricks, and said mortar lock tabs are adapted, when embedded within a cured mortar matrix, to exert, in response to a tensile force away from said metal sheet, a force along a vertical axis, on the brick, in an opposite direction to a force applied to the brick along a vertical axis by said groove retaining tab, to thereby retain the brick against the panel.
