Solution Overview

Problem

Existing egg sorting machines in the poultry industry face challenges in achieving optimal positioning and lighting conditions for reliable and efficient sex determination of avian eggs, leading to suboptimal examination results.

Innovation Solution

A shuttle system that integrates a holding assembly and lighting system, allowing for secure positioning and illumination of eggs from multiple angles, with a base and flange configuration that supports the egg from both ends and includes movable lighting devices powered externally to prevent hindrance and ensure reliable operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If eggs are positioned in a tray where they can take any position, then the device is simple to manufacture, but the positioning and lighting conditions are suboptimal for reliable examination

Engineering Contradiction:
Improveexamination reliabilityVSAvoidpositioning system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The holding assembly is segmented into a base with a lower cavity and a flange with an upper cavity, allowing independent positioning of each component to achieve optimal egg presentation. This segmentation enables precise control of egg orientation while maintaining manufacturing simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The shuttle acts as an intermediary device between the egg tray and the examination system. It provides a standardized holding structure that ensures optimal positioning and lighting conditions, mediating between the simple tray system and the requirements for reliable examination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If light sources are positioned on only one side of the object, then the device complexity is reduced, but the lighting conditions are insufficient for optimal presentation

Engineering Contradiction:
Improvelighting qualityVSAvoidlighting system complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The lighting system is segmented into multiple independent light sources positioned at different locations (upper cavity, lower cavity, and lateral positions). This allows optimal illumination from multiple angles while keeping each individual light source simple and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Lighting is provided from multiple spatial dimensions (upper, lower, and lateral directions) rather than a single direction. This multi-dimensional approach ensures comprehensive illumination of the egg for optimal presentation during examination.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If the holding assembly occupies a spaced position allowing object removal, then ease of operation is improved, but the object cannot be held and immobilized during movement

Engineering Contradiction:
Improveobject holding stabilityVSAvoidobject loading/unloading ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The holding assembly dynamically transitions between two states: a spaced position for easy loading/unloading of eggs, and a holding position where the upper and lower cavities come together to firmly immobilize the egg during movement and examination. This dynamic adjustment resolves the contradiction between ease of operation and holding stability.

Inventive Principle:
Principle #15Dynamics

4Reliability

If lighting devices are integrated into the holding assembly, then the structure is more compact, but the lighting devices may be hindered and reliable operation compromised

Engineering Contradiction:
Improvelighting device operation reliabilityVSAvoidelectrical connection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Electrical connector assemblies act as intermediaries between the external power source and the lighting devices. This allows the lighting devices to be integrated into the holding assembly for compactness while maintaining reliable electrical connections through the connector interface, resolving the contradiction between integration and operational reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)
