Passive Air Flow Final Hatching Holder for Egg Incubation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for incubating hatching eggs are animal-unfriendly, leading to variations in hatching times, stress, dehydration, and health risks due to inadequate air quality and handling, as well as being costly and labor-intensive.
Innovation Solution
A final hatching holder with passive air flow means, such as Venturi tubes, that maintains a natural air flow around eggs, allowing for convection-based temperature regulation and reducing the need for active conditioning systems, enabling eggs to be transported and hatched on-site in a poultry farm, thereby minimizing stress and improving animal welfare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active conditioning means are used to control temperature, air movements and humidity in the final hatching machine, then the hatching process can be precisely controlled, but the device becomes complex, expensive and labor-intensive to operate
Solution Approach 1:
The patent employs passive air flow means that automatically generate natural air flow and convection currents without requiring external power sources or active control systems. The air flow means self-regulate temperature and humidity through natural physical processes, eliminating the need for complex active conditioning equipment while maintaining reliable hatching process control.
Solution Approach 2:
The invention replaces active mechanical conditioning systems (fans, heaters, humidifiers) with passive physical phenomena. Natural convection and air flow replace mechanical air movement systems, and passive heat transfer replaces active heating/cooling mechanisms, thereby simplifying the overall system while preserving functional effectiveness.
2Object-affected harmful factors
If fertilized eggs are transported to a poultry farm for final hatching, then animal welfare is improved by reducing stress and dehydration, but the hatching process becomes more difficult to control compared to centralized incubation
Solution Approach 1:
The passive air flow means automatically regulate the hatching environment through natural convection and air flow, requiring no manual intervention or complex control systems. This self-regulating mechanism maintains ease of operation while transporting eggs to poultry farms, as the system adapts to environmental conditions without requiring active management.
Solution Approach 2:
The final hatching holder with integrated passive air flow means serves multiple functions: it protects eggs during transport, provides automatic temperature and humidity regulation during hatching, and requires minimal operational input. This multi-functionality maintains ease of operation across different locations and conditions.
3Device complexity
If passive air flow means are used instead of active conditioning systems, then the device complexity and cost are reduced, but the precision of temperature and humidity control may be compromised
Solution Approach 1:
The passive air flow means are designed with specific geometric parameters and configurations that optimize natural convection and air flow patterns. By carefully adjusting design parameters such as air flow path dimensions, opening sizes, and structural geometry, the system achieves precise temperature and humidity control through passive physical processes alone, without compromising control accuracy.

Function Achieved in This Case
This solution reduces stress and health risks for chicks, improves animal welfare, and eliminates the need for expensive and complex incubator machines, making the hatching process more efficient and cost-effective by using passive air flow for temperature control and natural ventilation.
Implementation Method 1
The final hatching holder is provided with air flow means for creating a natural air flow along the plurality of hatching eggs, thus providing heating and/or cooling, depending on the phase in which the hatching egg finds itself

AI summary
The invention relates to a final hatching holder for use in a method of hatching eggs. The method comprises the steps of providing a plurality of hatching eggs and placing said eggs in an incubator in a pre-hatching step. In a transport step, a number of fertilized eggs out of the plurality of hatching eggs are transported to a poultry farm. The method further comprises a preparatory step in which the number of fertilized eggs are placed in a final hatching holder. The final hatching holder is provided with air flow means which are designed to achieve convection through a natural flow of air along the plurality of hatching eggs. In a final hatching step, the final hatching holder with the number of fertilized eggs therein is placed in a stable of the poultry farm so that the number of fertilized hatching eggs are finally hatched.
