Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Animal ear tags pose a risk of infection due to the perforation of the ears, which can lead to bacterial and pathogenic microorganism entry, increasing the risk of wound inflammation and disease spread within livestock herds.

Innovation Solution

Incorporating an antimicrobial additive, particularly silver-based, into the plastic of animal ear tags to inhibit microbial growth and provide long-term protection against pathogens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If animal ear tags are applied by ear perforation, then livestock identification and traceability are improved, but the risk of infection and wound inflammation increases

Engineering Contradiction:

Improveidentification reliabilityVSAvoidinfection risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The antimicrobial additive is incorporated into the plastic material before the ear tag is applied to the livestock. This preliminary incorporation ensures that the antimicrobial protection is already present in the tag itself, ready to act immediately upon contact with the wound site during application.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The antimicrobial additive acts as an intermediary substance between the ear tag and the livestock's ear tissue. It mediates the interaction by providing a protective barrier that prevents harmful microorganisms from the tag or environment from entering the wound, while allowing the tag to fulfill its identification function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If antimicrobial additive is applied only to the surface of the ear tag, then the application process is simplified, but the protection duration is limited due to superficial removal

Engineering Contradiction:

Improveapplication simplicityVSAvoidprotection duration

Core Design Contradiction:

Ease of manufactureVSDuration of action of stationary object

Solution Approach 1:

The antimicrobial additive is merged with the plastic material itself, combining two previously separate elements (the tag structure and the antimicrobial agent) into a single integrated component. This ensures that the protective function is inherent to the tag and cannot be separated or removed independently.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The ear tag is made from a composite material consisting of plastic and antimicrobial additive. This composite structure provides both the mechanical functionality of the tag and the biological protection of the antimicrobial agent, with the additive distributed throughout the material matrix for sustained release.

Inventive Principle:

Principle #40Composite materials
