Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Garage doors lack effective solutions to allow airflow while keeping out debris and exhaust fumes, especially when partially opened, which can lead to increased temperatures and unwanted entry of particles.

Innovation Solution

A drop-down breeze screen system comprising a center bracket, end brackets, back braces, and breeze screens that attach to the garage door, allowing airflow through fine mesh while preventing debris and exhaust fumes from entering, utilizing lock pins and slide brackets for secure operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the garage door is opened partially to allow airflow, then ventilation is improved, but debris and exhaust fumes can enter the garage

Engineering Contradiction:

ImproveventilationVSAvoiddebris and exhaust fumes entry

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The breeze screen is divided into multiple panels that can be independently positioned. Each panel contains a fine mesh screen that segments the opening, allowing airflow while blocking debris and fumes. The panels can be adjusted to different positions to control ventilation while maintaining protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fine mesh screen acts as an intermediary element between the garage interior and exterior. It mediates the airflow by allowing air molecules to pass through while blocking larger particles like leaves, trash, and exhaust fumes, thus enabling ventilation without direct exposure to harmful external factors.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a solid barrier is used to block debris, then protection is improved, but airflow is reduced

Engineering Contradiction:

Improvedebris blockingVSAvoidairflow

Core Design Contradiction:

Object-affected harmful factorsVSUse of energy by moving object

Solution Approach 1:

The breeze screen utilizes fine mesh screen material with porous structure. The mesh size is small enough to block debris particles while large enough to allow air molecules to pass through freely. This porous structure enables simultaneous achievement of debris protection and airflow maintenance.

Inventive Principle:

Principle #31Porous materials

AI summary

The “Breeze screen” invention concept is designed to serve as a simulated natural “breeze gate” to keep garages cool and clean when they are opened. The mesh “breeze gate” feature serves to keep garbage and debris out of the inside garage space, while allowing the natural outdoor air ventilation in to keep the garage cool. It attaches to the existing garage door and can be “dropped down” and locked in place for security with its use. It functions by the design of a fine mesh panel or “screen” network, made of either metal, aluminum, plastic or other fabric of manufacturer's choice to allow airflow through the fine “air holes” that make up the “breeze gate” or “breeze screen” concept. Thus allowing air through to keep the garage cooler, but keeping larger unsightly particles out of the garage, such as leaves, trash and debris.
