Metal roof mounting brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing roof attachment solutions for solar mounting and snow guard systems on corrugated and R-panel trapezoidal metal roofs are limited by the need for specific brackets that match each unique roof profile, making universal brackets either expensive or complex to use.
Innovation Solution
The development of universal angle-adjustable and width-adjustable brackets that can be adjusted to fit various corrugated and R-panel trapezoidal metal roof profiles, featuring rotating and sliding components to secure to the roof with screws, allowing for a single set of brackets to accommodate multiple profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specific brackets are used for each unique roof profile, then the bracket fits the roof profile securely, but the device complexity and quantity of bracket types increases
Solution Approach 1:
The mounting bracket is designed with adjustable components that allow a single bracket type to fit multiple roof profiles (corrugated, R-panel, standing seam). The bracket includes adjustable arms and positioning mechanisms that can be configured to match different roof geometries, eliminating the need for multiple specific bracket types for different roof profiles.
Solution Approach 2:
The bracket incorporates movable and adjustable parts that can be repositioned during installation to accommodate various roof profiles. The adjustable arms can be moved to different positions and angles, allowing the same bracket to adapt to different roof geometries without requiring multiple fixed-design brackets.
2Device complexity
If universal brackets are designed to fit multiple profiles, then the device complexity and cost decreases, but the manufacturing precision and fit quality worsens
Solution Approach 1:
The bracket is divided into multiple adjustable segments and components that can be independently positioned. This segmentation allows each part to be adjusted to match the specific geometry of the roof profile being installed on, maintaining high fit quality while using a single universal bracket design.
Solution Approach 2:
The bracket design allows for changing geometric parameters (angles, lengths, positions) during installation to match different roof profiles. By making these parameters adjustable rather than fixed, the bracket maintains precise fit across multiple roof types without requiring different bracket designs.
3Reliability
If multiple specific brackets are used for different profiles, then the fit quality is high, but the ease of operation and installation time increases
Solution Approach 1:
The universal mounting bracket can be used across multiple roof profiles (corrugated, R-panel, standing seam) without requiring installers to identify and select from multiple different bracket types. This reduces installation complexity and time while maintaining secure attachment through its adjustable components.
Solution Approach 2:
The adjustable components of the bracket allow installers to adapt the bracket to different roof profiles during installation rather than requiring pre-selection of specific bracket types. This dynamic adaptability simplifies the installation process and reduces the need for multiple bracket inventories.

AI summary
An adjustable bracket for a metal roof includes a bolt and a top platform with a hole sized to receive the bolt. The top platform provides a flat surface on which can be attached an L bracket. A left bracket has a curved portion with a slot for receiving the bolt. A right bracket has a curved portion with a slot for receiving the bolt. A bottom nut is sized to fit and secure the bolt. Once the top platform, the slot in the left bracket and the slot in the right bracket receive the bolt, the slot in left bracket and the slot in right bracket allow adjustment of an angle of attachment of the angle-adjustable bracket to the metal roof, until the bolt is tightened by the bottom nut.
