Hatching Egg Inspection Cap Attachment Unit Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hatching egg inspection methods face challenges in preventing contamination and maintaining hygiene, particularly when dealing with spoiled or explosion eggs, as they require frequent sterilization and replacement of caps that come into contact with the eggs, which can disrupt productivity in large-scale hatcheries.
Innovation Solution
A hatching egg inspection apparatus with a cap attachment unit that allows for easy sterilization and replacement of caps, featuring a bellows-like connecting portion for secure contact with eggs of varying sizes and a light blocking design to prevent external light interference, along with protection plates for maintaining hygiene during inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If caps are frequently sterilized and replaced to prevent contamination, then hygiene is improved, but productivity deteriorates due to operational disruptions
Solution Approach 1:
The cap attachment unit is divided into a cap holder and multiple caps that can be independently replaced. When one cap becomes contaminated, only that specific cap needs to be replaced rather than sterilizing or replacing the entire attachment unit, thus maintaining hygiene while minimizing operational disruption to productivity
Solution Approach 2:
Contaminated caps are designed to be easily discarded and replaced with fresh caps. The cap holder retains the functional structure while individual caps are consumable components that can be quickly exchanged, separating the permanent fixture from the disposable elements to maintain hygiene without compromising productivity
2Measurement precision
If caps are designed for secure contact with eggs of varying sizes, then measurement precision is improved, but device complexity increases due to bellows-like connecting portions
Solution Approach 1:
The bellows-like connecting portion uses a flexible, accordion-style structure that can expand and contract to accommodate eggs of different sizes. This flexible design maintains secure contact and consistent optical alignment for accurate viability determination while avoiding the need for complex adjustable mechanisms or multiple specialized caps for different egg sizes
3Measurement precision
If light blocking design is implemented to prevent external light interference, then measurement precision is improved, but device complexity increases due to additional protection plates
Solution Approach 1:
The light-blocking function is merged into the cap structure itself rather than being a separate system. The cap and its connecting portion are designed with inherent light-blocking properties, combining the functions of egg contact, light blocking, and structural connection into a single integrated component, thereby improving measurement precision without significantly increasing overall device complexity
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 apparatus effectively prevents contamination and maintains hygiene without hampering productivity by allowing for efficient sterilization and replacement of caps, ensuring accurate viability determination and reducing the risk of cross-infection among healthy eggs.
Implementation Method 1
the viability is determined by emitting the prescribed light toward a hatching egg and analyzing a time-varying component of the light that has transmitted through the hatching egg
Implementation Method 2
featuring a bellows-like connecting portion for secure contact with eggs of varying sizes

AI summary
A hatching egg inspection apparatus includes a loader unit (2), an inspection unit (3) for determining the viability or the like as to whether a hatching egg is an unfertilized egg or a growth-stopping egg, a rejection unit (4) for rejecting a hatching egg determined to be an unfertilized egg or the like, and an unloader unit (5) for sending a hatching egg toward the next step. The inspection unit (3) is provided with a light emitting unit (11) for emitting prescribed light toward the hatching egg, a cap attachment unit (16) through which the light having been emitted to the hatching egg and having transmitted through the hatching egg passes, and a light receiving unit (22) for receiving the light that has passed through the cap attachment unit (16). The cap attachment unit (16) includes a cylindrical cap (20) coming into contact with the hatching egg, and a plate (17) to which the cap (20) is attached. The cap attachment unit (16) is slidably held by a guide rail (21).
