Solution Overview

Problem

Conventional roof ridge vent structures require separate inventory and installation for narrow and wide cap shingles, leading to increased manufacturing, shipping, and storage costs due to the need for duplicate vent structures.

Innovation Solution

A single, adjustable roof ridge vent structure that can be modified on-site to accommodate either 9-inch or 12-inch cap shingles by using a separation line to alter its width, allowing it to be used with both standard widths without the need for duplicate inventory.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If separate vent structures are manufactured for narrow and wide cap shingles, then each specific vent structure can be precisely matched to its corresponding shingle width, but manufacturing costs, shipping costs, and storage costs increase due to the need for duplicate inventory

Engineering Contradiction:
Improvevent structure width matchingVSAvoidinventory quantity
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The ridge vent structure is designed with a universal width that can accommodate both narrow (9-inch) and wide (12-inch) cap shingles. The structure includes a cut line that allows it to be divided into two sections, enabling a single vent design to serve multiple shingle width requirements without needing separate inventory for each size.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The ridge vent structure incorporates a cut line that enables it to be divided into two separate sections. This segmentation allows the single vent structure to be customized at the jobsite to match either narrow or wide cap shingles, eliminating the need to manufacture and store duplicate vent structures for different shingle widths.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If manufacturers maintain duplicate inventories of wide and narrow vent structures, then both narrow and wide cap shingle projects can be fulfilled, but costs of manufacturing, shipping, distribution, and storing increase

Engineering Contradiction:
Improvecompatibility with shingle widthsVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

A single ridge vent structure design serves both narrow and wide cap shingle applications. The structure includes a predetermined cut line that allows it to be divided into two sections, enabling one universal vent design to replace the need for maintaining separate inventories of wide and narrow vent structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The ridge vent structure is designed to be dynamically adaptable at the jobsite through the cut line, allowing the same manufactured structure to be configured for different shingle widths based on project requirements. This dynamic adjustment eliminates the need for manufacturers to produce multiple static vent size variants.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If a single ridge vent structure is used for both narrow and wide cap shingles, then inventory maintenance is simplified and distribution costs are reduced, but the structure must be modified on-site to accommodate different shingle widths

Engineering Contradiction:
Improveinventory varietyVSAvoidinstallation complexity
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The ridge vent structure includes a predetermined cut line that facilitates easy division into two sections. This segmentation enables simple on-site modification to accommodate different shingle widths without requiring complex tools or procedures, balancing inventory simplification with installation ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cut line is predetermined and incorporated into the manufacturing process, preparing the vent structure in advance for potential division. This preliminary action simplifies the on-site modification process, as the cut line provides a ready guide for workers to divide the vent structure appropriately for the specific shingle width being used.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If duplicate vent structures are produced and shipped, then specific sizes can be delivered to match cap shingles, but the risk of accidental delivery of the wrong size increases and distribution inefficiency occurs

Engineering Contradiction:
Improvecorrect size deliveryVSAvoiddistribution efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Manufacturers produce and ship only one universal ridge vent structure size that can accommodate both narrow and wide cap shingles. This eliminates the risk of delivering the wrong size vent structure, as a single universal design replaces the need for multiple size-specific variants in the distribution system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the functionality of multiple vent structure sizes into a single universal design. By combining the capabilities of narrow and wide vent structures into one product that can be divided at the cut line, the system eliminates distribution inefficiencies associated with managing multiple size variants.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A roof ridge vent is formed with separation lines parallel with its outer edges which permit separation of the outer edge portions of the structure. In its original configuration, the roof vent structure may be used with wide cap shingles. Removal of the outer edge portions permits the ridge vent to be used in connection with narrower cap shingles.
