Roof Edge Bracket for Thick Insulation Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof edge mounting systems struggle to securely attach roof trim to buildings with multiple layers of insulation, particularly over pre-cast concrete walls, as the traditional wood nailer often rots or is unsuitable, and existing solutions do not effectively extend the attachment height to accommodate thicker insulation layers.
Innovation Solution
A roof edge mounting bracket with a base member and vertical attachment flange, which includes a lower and upper portion, allowing for adjustable height and angle configurations to accommodate various insulation depths, and can be secured to different types of nailers or substrates, including pre-cast concrete walls and corrugated metal decks, using fasteners and self-tapping screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple layers of insulation are added to increase insulation thickness, then insulation efficiency is improved, but the attachment height of roof trim to the nailer becomes too low
Solution Approach 1:
The patent introduces a nailer extension as an intermediary component between the existing nailer and the roof trim. This extension allows the roof trim to be attached at a higher position, accommodating the increased insulation thickness while maintaining proper attachment height for the trim.
Solution Approach 2:
The solution extends the attachment system vertically by adding a nailer extension that projects upward from the original nailer position. This dimensional extension creates a new attachment plane at a higher elevation, resolving the conflict between insulation thickness and attachment height.
2Ease of manufacture
If wood nailer is used for mounting roof trim, then installation is simplified, but the wood nailer may rot and become unsuitable for attachment
Solution Approach 1:
The nailer extension serves as a mediator that transfers the attachment function from the potentially rotting wood nailer to a more durable substrate. The extension can be attached to the wood nailer temporarily and then used to mount the roof trim independently, allowing the trim to be secured to a more reliable surface.
Solution Approach 2:
The mounting system is segmented into separate components: the original nailer, the nailer extension, and the roof trim attachment. This segmentation allows the extension to be a replaceable component that can be made from more durable materials or attached to a more reliable substrate.
3Ease of operation
If roof trim is attached directly to the nailer, then the attachment process is simple, but the lower portion of roof trim cannot be reasonably secured when insulation is extended
Solution Approach 1:
The nailer extension acts as a mediator that bridges the gap between the fixed nailer position and the need for higher attachment points. It provides a new attachment surface that accommodates extended insulation while maintaining a simple fastening process through pre-drilled holes and alignment features.
Solution Approach 2:
The solution provides adaptability through adjustable features in the nailer extension, such as variable positioning or configurable attachment points, allowing the system to adapt to different insulation thicknesses and building configurations while maintaining operational simplicity.
