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

VSEngineering 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

Engineering Contradiction:
Improveassembly simplicityVSAvoidcorrosion risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveroof structure strengthVSAvoidnumber of brackets
Core Design Contradiction:
StrengthVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveassembly precisionVSAvoidsharp edges
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

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.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
