Folded-Layer Roof Deck Flanges for Balanced Energy Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing metal deck designs often result in unbalanced energy potential profiles due to restrictions from concrete volumes, composite interlocking, and aesthetics, leading to inefficient material utilization and increased processing costs.
Innovation Solution
The use of folded-layered, embedded sub-elements in structural and architectural members allows for a unitary or single skin design, optimizing material usage and enabling the creation of balanced energy profiles by adding material to the top flange to match the bottom flange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a profile is designed with unequal top and bottom flanges to meet aesthetic requirements for finished ceilings, then the aesthetic appearance is improved, but the energy potential distribution becomes unbalanced resulting in poor material utilization
Solution Approach 1:
The patent applies nesting by placing additional flange material inside the existing profile structure. The nested flange is positioned within the space between the top flange and the web, utilizing the internal volume of the profile to add material where needed without increasing the external dimensions or compromising aesthetic appearance.
Solution Approach 2:
The patent transitions from a two-dimensional flange design to a three-dimensional nested flange structure. By adding depth to the flange through nesting, the design achieves balanced energy potential distribution while maintaining the original external profile dimensions and aesthetic characteristics.
2Loss of energy
If two profiles are attached in a back-to-back configuration to balance energy potential, then the energy potential distribution is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent merges the function of two separate back-to-back profiles into a single integrated profile structure. The nested flange is formed as part of the same continuous metal sheet as the main profile, eliminating the need for separate components and their associated connection hardware while achieving the same energy potential balance.
Solution Approach 2:
The single profile with nested flange serves multiple functions simultaneously: it provides the structural load-bearing capacity, achieves balanced energy potential distribution, maintains aesthetic appearance, and simplifies installation. This multi-functional design replaces the need for complex multi-profile configurations.
3Loss of energy
If additional material is added to the top flange to balance energy potential, then the energy potential distribution is improved, but the manufacturing complexity increases
Solution Approach 1:
The nested flange is formed during the initial profile fabrication process through pre-bending and shaping operations. By incorporating the nested structure into the base metal sheet before final assembly, the patent eliminates the need for subsequent welding, bolting, or other complex manufacturing steps that would be required to add material after profile production.

Function Achieved in This Case
This approach enhances the structural characteristics of metal decks, improves material efficiency, reduces costs, and provides a balanced energy profile, while also allowing for appealing finished ceilings and improved buckling resistance.

AI summary
Decking with a panel of uniform thickness sheet metal has a repeating pattern of top flanges and bottom flanges connected by webs therebetween. At least one flange is made up of a plurality of folded-layer segments adjacent to each other in a stacked position to increase the thickness of the flange. Additionally a structural member extending along a longitudinal axis has a uniform thickness plate folded back onto itself about the longitudinal axis or an axis parallel to the longitudinal axis to increase the thickness and provide greater resistance to buckling in response to compressive forces. Such structural members not only provides certain structural advantages but also may provide an aesthetically pleasing appearance.
