Hip and Ridge Roofing Shingle Perforation Design

Solution Overview

Problem

Current methods for manufacturing hip and ridge roofing materials are inefficient, lacking in precision and ease of application, particularly in forming shingles for complex roof intersections like hips and ridges.

Innovation Solution

The development of shingle blanks with an underlay portion and an overlay portion, where the overlay portion has continuous layered segments with a sealant bead and perforation lines that allow for easy separation into hip and ridge shingles, facilitating efficient installation across intersections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional methods are used to manufacture hip and ridge roofing materials, then the manufacturing process is simpler, but the efficiency and precision of forming shingles for complex roof intersections deteriorates

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidmanufacturing process complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The shingle blank is divided into distinct functional portions: an underlay portion and an overlay portion with continuous layered segments. This segmentation allows each portion to be manufactured and prepared separately, then assembled together, improving manufacturing efficiency while maintaining process manageability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The overlay portion is pre-formed with continuous layered segments and sealant beads before final assembly. The perforation lines are also pre-established in the shingle blank, allowing for precise and easy separation during installation without requiring complex on-site manufacturing operations

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If shingle blanks are manufactured with pre-formed overlay portions and perforation lines, then the ease of separation and installation improves, but the manufacturing process complexity increases

Engineering Contradiction:

Improveease of separation and installationVSAvoidmanufacturing process complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

3Reliability

If the overlay portion has continuous layered segments with sealant bead, then the coverage and protection of roof intersections improves, but the manufacturing and installation time increases

Engineering Contradiction:

Improvecoverage and protectionVSAvoidmanufacturing and installation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The overlay portion is pre-formed with continuous layered segments and sealant beads before final assembly. The perforation lines are also pre-established in the shingle blank, allowing for precise and easy separation during installation without requiring complex on-site manufacturing operations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The continuous layered segments in the overlay portion provide uninterrupted coverage across the ridge or hip intersection, ensuring consistent protection without gaps. The continuous nature of the layers maintains reliability while the pre-formed structure reduces assembly time compared to joining separate pieces

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Shingle blanks are provided. The shingle blanks include an underlay portion having a substrate coated with an asphalt coating and granules, the underlay portion having an upper edge and a lower edge. An overlay portion is adhered to the underlay portion, the overlay portion having a plurality of continuous layered segments, the layered segments having a sealant bead therebetween. A plurality of perforation lines extend in a substantially perpendicular direction from the upper edge to the lower edge of the underlay portion. The plurality of perforation lines are sufficient to facilitate separation of the shingle blank to form hip and ridge roofing shingles configured for application across a ridge or hip.
