Foundation vent cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foundation vent solutions lack an aesthetically appealing and effective means to cover ventilation openings while ensuring optimal airflow and preventing entry of small creatures and gases.
Innovation Solution
A foundation vent cover comprising a mesh screen supported by a rigid frame with counterbored holes for fasteners, allowing for secure attachment over foundation openings, providing both airflow and an aesthetically pleasing appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a traditional foundation vent with grill and mesh screen is used, then ventilation function is achieved, but aesthetic appearance is compromised
Solution Approach 1:
The patent combines the mesh screen and frame into a single integrated vent cover assembly that can be installed as one unit. The mesh screen is attached to the frame during manufacturing, eliminating the need for separate installation steps and reducing overall system complexity while maintaining aesthetic appearance.
Solution Approach 2:
The mesh screen is pre-attached to the frame during manufacturing before installation at the building site. This preliminary action ensures proper alignment and attachment, simplifying the installation process and reducing on-site complexity while delivering the desired aesthetic appearance.
2Object-affected harmful factors
If mesh screen is made finer to prevent small creatures entry, then protection effectiveness increases, but airflow is restricted
Solution Approach 1:
The patent employs a mesh screen with optimized porosity that allows sufficient airflow while preventing entry of small creatures. The mesh geometry and opening size are carefully selected to balance filtration effectiveness with air permeability, achieving both protection and ventilation goals simultaneously.
3Stability of the object's composition
If frame width is increased to provide better support for mesh screen, then structural stability improves, but aesthetic appearance and airflow are compromised
Solution Approach 1:
The patent applies reinforcement strategically at specific locations where the mesh screen requires support, rather than uniformly increasing frame width throughout. This localized reinforcement maintains structural stability and mesh support while minimizing the frame's visual impact and preserving airflow openings.

AI summary
An apparatus and methods are provided for a foundation vent cover to be installed onto foundation ventilation openings of crawlspaces, garages, and buildings. The foundation vent cover comprises a mesh screen for covering a foundation vent opening and a supportive frame for retaining the mesh screen in an extended configuration over the foundation vent opening. The supportive frame may be made of a metal or any of various plastics. The mesh screen is made of a material that provides an aesthetically appealing appearance to the foundation opening while also allowing an optimal airflow through the foundation opening. The supportive frame includes holes to receive fasteners for attaching the foundation vent cover over the foundation opening. The fasteners may be wood screws, sheet metal screws, self-drilling screws, or threaded bolts and nuts. The holes may be counterbored or countersunk to hide at least a portion of the heads of the fasteners.
