Roof Tile Notch for Bracket Mounting Without Corrosion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof covering elements face challenges in efficient assembly to roof battens without metal holes, which can lead to corrosion issues, and require multiple brackets depending on force predictions, while also needing protection from sharp edges during installation.
Innovation Solution
A roof covering element with a wave-shaped rib featuring a notch for an angle bracket at the upper edge, where the notch is wider than the bracket, allowing for efficient assembly without metal holes and providing protection from sharp edges, with a cambered design that matches the roof's semicircular deflection and a horizontal connector for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If assembling holes are made in the horizontal surfaces of the panels for mounting to roof battens, then the assembly is simplified, but metal chips are created which become corrosion centres
Solution Approach 1:
The invention extracts the harmful metal holes from the assembly process by using a notched ending surface that allows direct placement of angle brackets without penetrating the panel surface. This eliminates metal chip generation while maintaining assembly simplicity.
Solution Approach 2:
The ending surface is segmented into a notched portion and a remaining portion. The notched portion accommodates the angle bracket while the remaining portion maintains structural integrity, allowing assembly without creating corrosion-prone holes through the entire panel.
2Strength
If multiple brackets are used depending on force predictions, then the structural strength is improved, but the device complexity and number of components increases
Solution Approach 1:
The invention merges the function of multiple brackets into a single integrated angle bracket by extending the notched ending surface to provide adequate support area. This reduces component count while maintaining the required structural strength through optimized surface geometry.
3Manufacturing precision
If the ending surface has a sharp edge after removing a section, then the assembly precision is improved, but the object-generated harmful factors increase due to sharp edges during installation
Solution Approach 1:
The invention applies beforehand cushioning by providing a rounded portion at the notched ending surface that prevents sharp edge formation. This rounded portion acts as a buffer during installation, eliminating harmful sharp edges while preserving assembly precision through the defined notch geometry.

AI summary
The roof covering element (tiles-like sheet) equipped with an angle bracket characterises by that the ending surface (3) of the roof covering element (1), in the wave-shaped rib of the upper edge surface (2), preferably in a part without assembling hole (4), has at least one notch (5), in which is placed an angle bracket (6), and said notch (5) width is bigger than the angle bracket (6) width.
