Ridge Ventilator Modular Design for High Snow-Load Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ridge ventilators are not easily customizable to accommodate different roof pitches and air flow requirements, particularly in high snow-load scenarios, which can lead to inadequate ventilation and premature roofing material failure.
Innovation Solution
A customizable high snow-load ridge ventilator system comprising support brackets, a perforated support, and a ridge cover with snap flanges and clips, allowing for adjustable attachment to various roof types and pitches, including corrugated roofs, with optional spacers for enhanced load carrying capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed design ridge ventilator is used, then the structure is simple and easy to manufacture, but it cannot accommodate different roof pitches and snow-load conditions
Solution Approach 1:
The ridge ventilator is divided into separate modular components including support brackets, perforated supports, ridge covers, and optional spacers. Each component can be independently selected and assembled to match specific roof pitches and snow-load requirements, providing adaptability without requiring a completely different design for each scenario.
Solution Approach 2:
The support brackets are designed with multiple configuration options and attachment methods that allow the same basic component to function across various roof types and pitches. The modular system enables a single product line to serve multiple functions and applications.
2Adaptability or versatility
If a customizable ridge ventilator with multiple components is used, then it can accommodate different roof configurations, but the device complexity increases
Solution Approach 1:
By segmenting the ventilator into standardized modular components, each part can be manufactured independently using optimized processes. The support brackets, perforated supports, and ridge covers are designed as discrete units that can be produced efficiently and then assembled through simple connection mechanisms.
Solution Approach 2:
The modular components are designed with adjustable parameters and configurable features that allow customization through assembly rather than complex manufacturing. Variations in roof pitch and load requirements are accommodated by selecting and configuring existing components rather than creating entirely new parts.
3Reliability
If existing ridge ventilators are used in high snow-load scenarios, then installation is straightforward, but ventilation effectiveness is inadequate leading to roofing material failure
Solution Approach 1:
The modular components are designed to be pre-configured and pre-assembled to the appropriate specifications for anticipated snow-load conditions. Support brackets and spacers can be selected and positioned before final installation, ensuring the ventilator is properly configured to handle expected loads and maintain ventilation effectiveness.
Solution Approach 2:
The ventilator structure incorporates dynamic elements such as adjustable components and flexible connection points that can adapt to varying snow accumulation patterns and roof conditions. This allows the system to maintain its structural integrity and ventilation function under changing load conditions rather than being rigidly fixed.

AI summary
A high snow-load ridge ventilator includes a pair of support brackets, a perforated support, a ridge cover and a plurality of cover spacers. A bottom of one support bracket is attached to one side of a ventilation opening and a bottom of the other support bracket is attached to the other side of the ventilation opening. A plurality of perforated support spacers may be attached to the roof along a length of a pair of support brackets to provide additional load carrying capability. The perforated support is a formed plate with a plurality of perforated openings. The perforated support is attached to a top of the pair of support brackets. The plurality of cover spacers are attached to a top of the perforated support. The ridge cover includes snap clips that are sized to receive snap flanges extending from the perforated support.
