Poultry Aviary Door Arrangement With One Vertically Movable Closure

Solution Overview

Problem

Existing rearing-keeping facilities for poultry animals require multiple separate closing means for opening and closing lateral openings, increasing mechanical complexity and operational effort, and often block access to the animals.

Innovation Solution

A vertically displaceable door arrangement with a single closing means, such as a grating, that can open or close both upper and lower openings, guided by a system of rails, allowing flexible access and reduced mechanical complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate closing means are provided for each rearing plane, then each opening can be closed independently, but the mechanical complexity and operating effort increase significantly

Engineering Contradiction:

ImproveIndependent opening controlVSAvoidMechanical complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate closing means into a single closing means that can simultaneously close multiple lateral openings of different rearing planes. This single closing means is designed to span across openings and can be moved to different positions to close either the first opening, the second opening, or both openings independently, thereby reducing mechanical complexity while maintaining independent control capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single closing means is designed with multi-functionality to perform multiple closing operations. It can be positioned to close the first lateral opening of the first rearing plane, the second lateral opening of the second rearing plane, or both openings simultaneously, making one device serve the function of multiple separate closing means

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate closing means are provided for each rearing plane, then each opening can be closed independently, but the operating effort increases significantly

Engineering Contradiction:

ImproveIndependent opening controlVSAvoidOperating effort

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

3Ease of operation

If displaceable closing means are used, then openings can be opened and closed, but the closing means block access to the poultry animals

Engineering Contradiction:

ImproveOpening accessibilityVSAvoidAccess blocking

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent utilizes vertical displacement of the closing means to resolve the access blocking problem. The single closing means can be moved vertically between a first position where it closes the lateral openings and a second position where it is displaced out of the way to allow unobstructed access to the poultry animals. This vertical dimension movement allows the closing means to perform its function without permanently blocking access

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A rearing-keeping facility for the staggered rearing of poultry animals, in particular rearing aviary, is disclosed and includes at least one first rearing plane and a second rearing plane arranged above the first rearing plane. The rearing planes are configured for keeping the poultry animals, and the first rearing plane has a first lateral opening towards at least one side of the rearing-keeping facility and the second rearing plane has a second lateral opening towards the one side. A door arrangement is provided for closing the openings. The door arrangement has a closure arranged in a vertically displaceable manner with respect to the two openings and configured for releasing or for closing the first opening, the second opening, and both openings.
