Attic vent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attic vents require a third diverter component for effective water exclusion, adding complexity and potentially increasing the risk of water leakage during heavy rains.
Innovation Solution
A two-part attic vent design featuring a base component with a diverter extension wall orthogonal to the mounting plate and a dome-shaped cover that integrates a baffle structure to prevent water entry, eliminating the need for a separate diverter component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a three-part construction with a separate diverter component is used, then water exclusion capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the diverter function and baffle function into a single integrated base component. The diverter extension wall is formed as one piece with the base, eliminating the need for separate diverter and baffle components. This merging reduces assembly complexity while maintaining water exclusion capability through the integrated structural design.
Solution Approach 2:
The base component performs multiple functions simultaneously: it provides structural support, directs water away from the vent opening via the diverter extension wall, and prevents water entry through the integral baffle. This multi-functional design eliminates the need for separate specialized components while achieving comprehensive water protection.
2Reliability
If a three-part construction with multiple components is used, then water diversion effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The diverter extension wall and baffle are manufactured as a single integral component rather than separate parts. This reduces the number of manufacturing steps, eliminates the need for precise alignment and sealing between multiple components, and simplifies quality control while maintaining effective water diversion performance.
3Device complexity
If a two-part construction is used, then device complexity is reduced, but water exclusion capability may worsen
Solution Approach 1:
While reducing to two main components (base and cover), the base itself is segmented into functional zones: the mounting plate, diverter extension wall, and integral baffle. This segmentation within the base component maintains comprehensive water protection capabilities while simplifying the overall assembly to just two primary parts.

AI summary
An attic vent has a base component, a dome-shaped cover, and a mounting mechanism for mounting the dome-shaped cover onto and over the base component. The base component has a mounting plate with a vent opening having a vertical wall surrounding the vent opening and extending upwardly from the mounting plate and to an upper rim. A diverter extension wall extends upwardly from the upper rim on a plane that is orthogonal to the mounting plate, and further an open grill extends upwardly from the upper rim at an inward angle from the diverter extension wall. The dome-shaped cover extends outwardly and downwardly to a bottom edge, while covering the open grill. The mounting mechanism further extends downwardly over the vertical wall and is spaced from the mounting plate.
