EDM-Marked Test Specimens for Permanent Property Identification

Solution Overview

Problem

Conventional methods for labeling miniature test specimens are prone to errors and markings can be easily obscured or removed, especially when specimens are handled and stored in batches, making it difficult to accurately identify material properties.

Innovation Solution

Integrally forming markings on the exterior surface of test specimens during production using electric discharge machining, micro-machining, or laser machining to ensure the markings are permanent and cannot be easily removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional labeling methods (paint, ink, adhesive labels) are used on miniature test specimens, then the labeling process is simple and quick, but the markings are easily obscured or removed during handling and storage

Engineering Contradiction:

Improvelabeling process simplicityVSAvoidmarking permanence

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The marking process is merged with the specimen manufacturing process. The electric discharge machining wire that cuts the specimen from the block simultaneously creates the identification marking on the specimen surface, combining two operations into one integrated process.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The identification marking is created in advance during the manufacturing process, before the specimen is subjected to handling, storage, or testing. This preliminary action ensures the marking is already permanently formed on the specimen surface before any potential damage could occur.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If labeling is delayed until after specimen production, then the manufacturing process is faster, but mistakes occur due to delays and handling

Engineering Contradiction:

Improvemanufacturing speedVSAvoidlabeling accuracy

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The identification marking is created in advance during the manufacturing process, before the specimen is subjected to handling, storage, or testing. This preliminary action ensures the marking is already permanently formed on the specimen surface before any potential damage could occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The marking process is merged with the specimen manufacturing process. The electric discharge machining wire that cuts the specimen from the block simultaneously creates the identification marking on the specimen surface, combining two operations into one integrated process.

Inventive Principle:

Principle #5Merging (Combining)

3Quantity of substance

If miniature test specimens are stored in batches and subjected to handling, then storage efficiency is improved, but the printed label markings become obscured or labels are removed

Engineering Contradiction:

Improvestorage densityVSAvoidmarking integrity

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The marking process is merged with the specimen manufacturing process. The electric discharge machining wire that cuts the specimen from the block simultaneously creates the identification marking on the specimen surface, combining two operations into one integrated process.

AI summary

A test specimen of a material has a marking on the test specimen that identifies at least one property of the material of the test specimen. The marking is integral with the test specimen and produced by electric discharge machining, micro-machining, and/or laser machining on the test specimen as the test specimen was produced by electric discharge machining, micro-machining, and/or laser machining from the material.
