Solution Overview

Problem

Current methods for delivering substances to specific embryonic structures within a developing avian egg are not automated, safe, or effective, as they lack the capability to target and inject substances into precise locations without damaging the embryo.

Innovation Solution

An automated Embryonic Structure Targeting Injection System (ESTIS) that aseptically opens the egg, detects and maps the location of embryonic structures using visual information, and precisely injects substances into specific locations within the egg, such as the heart or blood vessels, before sealing the egg to ensure safe development.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional injection devices are used to deliver substances to embryos, then substances can be injected into the egg, but the injection cannot be targeted to specific embryonic structures and may damage the embryo

Engineering Contradiction:
Improveinjection precisionVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system divides the injection process into distinct functional modules: an imaging module for locating embryonic structures, a positioning module for aligning the needle, and an injection module for substance delivery. This segmentation allows each module to be optimized independently while achieving precise targeted injection into specific embryonic structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary imaging and localization of embryonic structures before the injection process. The imaging module captures images of the embryo and identifies target structures in advance, allowing the positioning system to pre-align the needle before actual injection occurs, thereby ensuring precision while managing complexity through sequential operations.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automated injection systems are implemented, then processing speed increases, but the risk of damaging embryonic structures increases

Engineering Contradiction:
Improveeggs processed per hourVSAvoidembryo damage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system incorporates real-time feedback through imaging during the injection process. The imaging module continuously monitors needle position relative to embryonic structures, providing feedback that allows the control system to adjust positioning and prevent damage while maintaining automated high-speed processing of multiple eggs.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system replaces manual mechanical injection with an automated system that uses optical imaging for guidance and control. This substitution allows for more precise control at high speeds, as the optical feedback system can detect and respond to positional variations faster than manual operation, reducing damage risk while increasing productivity.

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

3Ease of operation

If the egg is opened for injection, then substances can be delivered to the embryo, but the embryo is exposed to contamination risk

Engineering Contradiction:
Improveinjection accessibilityVSAvoidaseptic condition
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system uses a controlled opening mechanism that creates a defined access point to the egg while maintaining a barrier between the external environment and the embryonic interior. The opening is minimized and controlled, serving as an intermediary access point that allows needle insertion while limiting contamination exposure, and is subsequently sealed to restore protective integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)
