Solution Overview

Problem

Existing methods for obtaining egg liquid from poultry eggs often result in liquid loss and contamination due to inefficient egg opening and shell handling, with too much freedom in egg positioning and inadequate shell treatment.

Innovation Solution

A device using a compact laser cutting or ultrasonic vibration system for precise egg opening, featuring a clamping mechanism and movable suction and blowing units to minimize shell parts in the liquid and enhance liquid retrieval efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a knife is used to smash the egg from beneath, then the egg shell is opened and liquid flows downwardly, but liquid is lost and egg shell parts are mixed in the liquid

Engineering Contradiction:
Improveegg processing efficiencyVSAvoidliquid loss
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The patent replaces the mechanical knife smashing system with a laser-based opening device. The laser creates precise openings in the egg shell without the chaotic smashing action, allowing controlled liquid flow while preventing loss and contamination with shell fragments.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent applies preliminary positioning and orientation of the egg before opening. The egg is positioned vertically with the blunt end upward, and the laser creates a controlled opening at the top, allowing liquid to flow downward in a controlled manner rather than being scattered by chaotic smashing.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If a knife is used to smash the egg from beneath, then the egg shell is opened, but egg shell parts are mixed in the liquid

Engineering Contradiction:
Improveegg processing efficiencyVSAvoidshell contamination
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical knife smashing system with a laser-based opening device. The laser creates precise openings in the egg shell without the chaotic smashing action, allowing controlled liquid flow while preventing loss and contamination with shell fragments.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary suction device that actively removes shell parts and debris from the liquid stream. This intermediary system separates the harmful shell fragments from the valuable liquid content, preventing contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If too much freedom is left in egg positioning, then the egg can be easily placed, but liquid retrieval holes are not well-determined

Engineering Contradiction:
Improveegg positioning easeVSAvoidhole positioning accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies preliminary positioning and orientation of the egg before opening. The egg is positioned vertically with the blunt end upward, and the laser creates a controlled opening at the top, allowing liquid to flow downward in a controlled manner rather than being scattered by chaotic smashing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms through the control device that monitors and adjusts the positioning and opening process. The control device coordinates the positioning system and laser opening device to ensure precise hole creation at the intended location, combining ease of placement with positioning accuracy.

Inventive Principle:
Principle #23Feedback

4Manufacturing precision

If shell treatment is improved for well-determined liquid retrieval holes, then hole positioning is accurate, but the device complexity increases

Engineering Contradiction:
Improvehole positioning accuracyVSAvoidegg opening system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical knife smashing system with a laser-based opening device. The laser creates precise openings in the egg shell without the chaotic smashing action, allowing controlled liquid flow while preventing loss and contamination with shell fragments.

Inventive Principle:
