Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the gender of chicken embryos in eggs are considered too slow, impractical, and unreliable for industrial-scale application.
Innovation Solution
A method that involves determining the location of entry on the eggshell based on various egg parameters, followed by taking an allantoic fluid sample from this location using a sample needle designed to minimize damage and maximize fluid collection, allowing for a more reliable gender determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gender determination is performed using known methods on chicken embryos, then gender identification can be achieved, but the process is too slow, impractical and unreliable for industrial-scale application
Solution Approach 1:
The patent performs gender determination at an early incubation stage (7-11 days) rather than waiting until hatching, enabling preliminary sorting of male and female embryos. This preliminary action allows industrial-scale processing while maintaining reliability through standardized sampling procedures and location-based fluid collection.
2Productivity
If allantoic fluid is sampled from any location in the egg, then sampling can be performed quickly, but the results are unreliable due to false outcomes from improper sampling locations
Solution Approach 1:
The patent specifies precise sampling locations on the eggshell surface based on egg parameters (dimensions, shape, orientation) to ensure the needle enters the correct region where allantoic fluid can be reliably collected. This local quality approach ensures that sampling is both quick and accurate by targeting specific zones remote from the air cell but accessible for fluid extraction.
Solution Approach 2:
The system uses egg parameters (dimensions, shape, orientation) to determine the optimal entry location for sampling. This feedback mechanism ensures that each egg is sampled at the correct location based on its specific characteristics, improving measurement precision while maintaining productivity through automated location calculation.
3Device complexity
If a standard needle is used for allantoic fluid sampling, then the equipment is simple, but the needle diameter causes unnecessary opening of the egg leading to bacterial intrusion and fluid loss
Solution Approach 1:
The patent specifies precise parameters for the sampling needle including diameter (0.5-0.8mm), length, and material properties to minimize damage to the egg while enabling effective fluid collection. These parameter changes optimize the needle design to balance simplicity with harm reduction, preventing bacterial intrusion and fluid loss while maintaining equipment simplicity.

AI summary
The present invention relates to a method for producing poultry, in particular chicken, the method comprising; a) incubating a batch of eggs in an incubating device during a first incubating period of between about 7 to about 11 days, and then, b) maintaining an egg in a predetermined sampling position during a settling time for allowing allantoic fluid to surface, c) determining a location of entry based on one or more egg parameters.
