Solution Overview
Problem
Existing hatching egg inspection methods face challenges in accurately determining viability due to subtle fluctuations in embryo vital signs, leading to mistaken determinations that affect chick production and vaccine manufacturing.
Innovation Solution
A hatching egg inspection apparatus with a two-dimensional arrangement of light emitting and receiving means, where only one light emitting means emits light at a time, and others within a prescribed range are turned off, to minimize interference and enhance accuracy in detecting vital signs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple light emitting means are used to inspect hatching eggs, then inspection coverage is improved, but light interference between adjacent eggs increases causing measurement errors
Solution Approach 1:
The inspection system divides the light emission function into separate, independently controllable light emitting means for each egg position. Each light emitting means is paired with its corresponding light receiving means, creating segmented inspection channels that prevent cross-interference while maintaining comprehensive coverage across multiple eggs.
Solution Approach 2:
The system employs periodic or sequential activation of light emitting means rather than continuous simultaneous emission. By controlling the timing of light emission from each source, the system ensures that when one light emitting means is active, others are dormant, eliminating mutual interference while maintaining inspection capability across all egg positions.
2Productivity
If light emitting means are activated simultaneously for all eggs, then inspection efficiency is improved, but light leakage and interference between adjacent eggs cause mistaken determinations
Solution Approach 1:
The system segments the inspection process into independent channels, with each light emitting means and its corresponding light receiving means forming a dedicated inspection pair. This segmentation allows the system to maintain high productivity by inspecting multiple eggs simultaneously while preventing interference through spatial and functional separation of each inspection channel.
Solution Approach 2:
Each inspection position is equipped with locally optimized light emitting and receiving means configured specifically for that position. The light receiving means is positioned to receive only the light from its corresponding light emitting means that has transmitted through the specific egg, creating localized inspection zones with high reliability that collectively achieve high overall productivity.
3Device complexity
If light receiving means are positioned close to light emitting means for compact design, then device complexity is reduced, but light interference from adjacent eggs increases
Solution Approach 1:
The system adopts a segmented configuration where each light emitting means and light receiving means form an independent inspection unit. These units are arranged in a one-to-one correspondence with egg positions, creating modular segments that can be configured compactly while maintaining sufficient spatial separation between adjacent units to prevent light interference.
Solution Approach 2:
The egg itself acts as an intermediary element that defines the optical path between light emitting means and light receiving means. By positioning the light receiving means to receive light that has transmitted through the egg, the system uses the egg as a natural mediator that blocks stray light from adjacent eggs while allowing the intended light path, thus reducing interference without requiring complex shielding structures.

AI summary
To reduce the incidence of mistaken determinations in hatching egg inspections. A hatching egg inspection apparatus includes: a plurality of light emitting means, the light emitting means being disposed two dimensionally at prescribed positions; light receiving means, which are provided in a one-to-one relationship with the light emitting parts and each of which receives light from the corresponding light emitting means; and an egg container, which is for arraying in advance a hatching egg between each of the light emitting means and the light receiving means corresponding thereto. Each hatching egg is inspected by the corresponding light receiving means that receives, among the lights from all the light emitting parts, transmitted light that transmitted through the interior of the hatching egg. When one light emitting means of the plurality of light emitting means is emitting light, other of the light emitting means within a prescribed range centered on the one light emitting means do not emit light.
