Solution Overview

Problem

Traditional roofing shingles lack the aesthetic appeal of thicker, more intricate designs like slate or wood shingles while requiring more material and installation time, and generating excess waste.

Innovation Solution

A two-layer laminated roofing shingle design with anterior and posterior layers, where the anterior tabs do not entirely cover the posterior layer, creating a variable thickness and reducing material usage, and allowing for efficient packing and installation, simulating a thicker appearance with fewer actual courses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional single-layer asphalt shingles are used, then installation is simple and material cost is low, but aesthetic appearance is poor and thickness is insufficient

Engineering Contradiction:

ImprovethicknessVSAvoidshingle structure

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The shingle is divided into multiple distinct layers: a base layer, a middle layer with tabs, and a top layer. This segmentation allows each layer to contribute specific visual characteristics, creating the appearance of greater thickness and complexity while using manageable amounts of material.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shingle layers are nested in a stacked arrangement where the middle layer is positioned between the base and top layers, and the tabs extend from the middle layer to create overlapping effects. This nested structure simulates the appearance of thicker, more complex shingles like slate or wood while maintaining a manageable composite construction.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Shape

If multiple layers of shingles are used to simulate thicker appearance, then aesthetic appeal increases, but material usage and installation time increase

Engineering Contradiction:

Improvevisual thicknessVSAvoidroofing material

Core Design Contradiction:

ShapeVSQuantity of substance

Solution Approach 1:

The shingle design copies the visual characteristics of thicker, more expensive shingles (slate or wood) by using a multi-layer composite structure with strategically placed tabs and varying layer thicknesses. This creates the illusion of greater thickness without requiring actual thick materials, thereby reducing overall material consumption while achieving the desired aesthetic appearance.

Inventive Principle:

Principle #26Copying

3Shape

If traditional thick shingles like slate or wood are used, then aesthetic appearance is superior, but weight and shipping cost increase

Engineering Contradiction:

ImprovethicknessVSAvoidshingle weight

Core Design Contradiction:

ShapeVSWeight of moving object

Solution Approach 1:

The shingle uses a composite construction combining a base layer, a middle layer with tabs, and a top layer, where each layer can be made from lighter materials compared to traditional thick slate or wood shingles. This composite approach achieves the desired visual thickness while significantly reducing the overall weight, making the shingles more economical for shipping and installation.

Inventive Principle:

Principle #40Composite materials

AI summary

A laminated roofing shingle is disclosed comprising a posterior layer with tabs spaced apart by openings and an anterior layer with tabs spaced apart by openings, wherein the anterior layer is positioned offset from the posterior layer such that it partially overlaps the posterior layer in a manner such that the anterior layer does not entirely overlap the surface of the posterior tabs. A roofing system comprising a plurality of courses of the shingles is also disclosed as well as a method of manufacturing the shingle.
