Embedment Bracket for Walk-in Freezer Floor Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current walk-in freezer and cooler floor constructions using plywood reinforcement materials often experience delamination issues under heavy loads, such as from carts, due to detachment or loosening from the surface.
Innovation Solution
Incorporating strategically placed brackets within the panel structure before filling with filler material, such as foam, which anchors the top metal skin and provides embedment strength, preventing delamination by mating with the metal skin and advancing vertically into the filler material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plywood reinforcement material is used to reinforce the wear surface, then additional support is provided, but the material becomes detached or loosened from the surface
Solution Approach 1:
The reinforcement system is segmented into multiple brackets distributed across the panel surface, each independently anchored in the filler material and attached to the metal skin. This segmentation allows each bracket to provide localized reinforcement while maintaining reliable attachment through direct bonding to both the metal skin and filler material, eliminating the delamination issues of plywood reinforcement.
2Reliability
If brackets are strategically placed into panels before filling with filler material, then delamination is prevented, but the manufacturing process becomes more complex
Solution Approach 1:
The brackets are strategically placed into the panels before the filler material is applied, allowing them to be properly positioned and anchored in advance. This preliminary action ensures that the brackets are securely embedded in the filler material and attached to the metal skin before the panel is completed, preventing delamination while integrating smoothly into the manufacturing process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents delamination of the top metal skin from the panel, enhancing structural integrity and reducing the need for additional reinforcement materials like plywood, thereby saving costs and simplifying installation while maintaining structural support.
Implementation Method 1
Once the filler material, for example foam, cures, the brackets will be anchored in the filler material

AI summary
A panel of a structure is provided that includes a first layer of material, a second layer of material, a filler material between the first layer of material and the second layer of material, and a bracket connected to the first layer of material. The bracket has a bottom flange spaced from the first layer of material. The filler material is between the first layer of material and the bottom flange securing the first layer of material to the filler material to function as an anchor and to provide embedment strength.
