Solution Overview

Problem

Existing methods for determining the gender of an embryo in an egg, such as those involving needle insertion, risk cross-infection, require additional operations to link results to eggs, and can cause embryo dehydration due to moisture evaporation.

Innovation Solution

A method involving a sealing means, such as a plug or sticker, is used to create a passage into the egg, which seals to prevent fluid loss and includes a biomarker to react with the allantoic fluid, allowing for non-invasive testing and linking results directly to the egg.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a needle is inserted into the interior of the egg to take a sample or inject fluid, then the test can be performed, but cross-infection may occur

Engineering Contradiction:

Improvetest accuracyVSAvoidcross-infection risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a sealing means as an intermediary element that establishes a controlled connection between the external testing equipment and the egg interior. This sealing means acts as a mediator that allows fluid sampling and injection while maintaining isolation between the external environment and the egg contents, thereby preventing cross-infection while enabling reliable testing.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional needle insertion mechanical system with a sealing means-based system. Instead of directly inserting a needle through the eggshell, the system uses a sealing mechanism that can be attached to the eggshell surface or inserted as a sealed unit, eliminating the need for open needle penetration and thus preventing contamination while maintaining testing functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If a needle is inserted into the egg to take a sample, then gender determination can be performed, but additional operations are required to link the result to the associated egg

Engineering Contradiction:

Improvegender determinationVSAvoidadditional linking operations

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines the sampling function and the identification function into a single integrated sealing means. The sealing means is uniquely associated with a specific egg through its attachment or insertion, and it contains or carries the sample. This merging of functions eliminates the need for separate operations to link test results to specific eggs, as the sealing means itself serves as both the sampling device and the identification carrier.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sealing means is designed to perform multiple functions: it seals the passage created in the eggshell, enables fluid sampling, enables fluid injection, and serves as a unique identifier for the associated egg. This multi-functionality reduces the number of separate operations required and directly links test results to the correct egg without additional linking steps.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If a passage is made in the eggshell for testing, then the test can be performed, but moisture evaporates from the egg causing the embryo to die

Engineering Contradiction:

Improvetest accessibilityVSAvoidembryo survival

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The sealing means functions as a flexible seal that can be attached to or inserted in the eggshell passage. It forms a barrier that prevents moisture evaporation through the passage opening while allowing the necessary testing operations to proceed. The sealing means maintains the integrity of the eggshell barrier, preventing dehydration of the embryo while enabling test access.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing means serves as an intermediary element that mediates between the need for test access and the need to maintain egg integrity. It creates a controlled interface that allows sampling and injection operations while simultaneously preventing moisture loss. The sealing means protects the embryo from dehydration by sealing the passage after the necessary testing operations are completed.

Inventive Principle:

Principle #24Intermediary (Mediator)
