Wall vent door assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall vent door assemblies for poultry houses lack adjustable and easily installable flexible hinge systems that provide effective sealing against light and wind, and are difficult to retrofit, especially in varying wall dimensions and shapes.
Innovation Solution
A vent door assembly featuring a flexible and resilient hinge system that extends along the door and frame edges, combined with a retainer screw assembly for adjusting the door closure, allowing for customizable installation in various wall openings and ensuring complete sealing and airflow direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard sealing system is used in prior art wall vent door assemblies, then the structure is simple, but the sealing effectiveness against light and wind is insufficient
Solution Approach 1:
The patent applies a flexible bulb seal that extends along the bottom edge of the door and contacts the frame when closed, creating an effective seal against light and wind. This flexible sealing element replaces rigid sealing mechanisms while maintaining simplicity in the overall structure.
2Adaptability or versatility
If cord systems are made stationary in prior art assemblies, then the installation is simpler, but the adaptability to different wall dimensions and shapes is reduced
Solution Approach 1:
The patent implements an adjustable cord system where the cord length can be modified to accommodate different wall dimensions and vent door configurations. The cord system allows for dynamic adjustment during installation and operation, enabling adaptation to various opening sizes and shapes while maintaining ease of use through a straightforward adjustment mechanism.
3Ease of operation
If fixed vent doors are used in prior art assemblies, then the manufacturing is simpler, but the ventilation control capability is limited
Solution Approach 1:
The patent employs a pivotable door mechanism that can rotate between closed and open positions, enabling dynamic ventilation control. The door is hinged at the bottom edge and can be positioned at various angles to regulate airflow, providing operational flexibility while maintaining a relatively simple mechanical design through the use of a basic hinge and cord system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a multifunctional hinge system for efficient door operation, complete sealing against light and wind, and easy installation in diverse wall dimensions, enhancing ventilation control and stability.
Implementation Method 1
a hinge comprising a flexible and resilient material forming two opposite edges each configured to be captured within a respective hinge-edge channel extending continuously along the hinge-edge of the mounting frame and the door, the flexible hinge material exerting force assisting in door opening

AI summary
A wall vent door assembly including a multi-functional hinge including flexible and resilient material extending continuously along the hinge edge of the door; one edge of the door is configured to accept and/or otherwise interface with a complimentary edge of the hinge material, and the adjacent hinge edge of the mounting frame is configured to accept and/or otherwise interface with another complimentary edge of the hinge material. Besides providing the hinge connection between the door and the adjacent frame, the flexible material also seals the interface to prevent entry of light and wind when the door is closed. The flexible and resilient hinge material also acts as a spring, exerting force to assist in the movement of the door from the closed position to open positions.
