Solution Overview

Problem

Traditional methods for determining the structure of conductive materials, such as metals, involve stressful testing processes that can alter the material's structure, making it difficult to distinguish between inherent defects and artifacts caused by the testing process, and are laborious, time-consuming, and limited to flat surfaces or require complex measurement techniques for 3D analysis.

Innovation Solution

A method using a charged electrolytic jet to remove conductive material from a workpiece's surface, forming a second surface without excessive stress, allowing for non-destructive testing and imaging, which can be used to determine microstructure or nanostructure, including grain size and inclusion content, without causing mechanical or thermal stress, enabling precise analysis of complex geometries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional mechanical or thermal stress testing methods are used to reveal the structure of conductive materials, then the structure can be revealed, but the stress added alters the structure and creates defects that are artifacts of the testing process rather than inherent defects

Engineering Contradiction:
Improvestructure revelation accuracyVSAvoiddefect identification accuracy
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent replaces mechanical stress testing methods with electrochemical dissolution using a charged electrolytic jet. Instead of applying mechanical or thermal stress to reveal structure, the invention uses controlled electrochemical removal of material to expose the underlying microstructure without inducing stress-related artifacts or altering the material's inherent properties.

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

Solution Approach 2:

The patent introduces an electrolytic jet as an intermediary medium between the imaging system and the conductive material. This electrolytic jet serves as a non-contact tool that removes material through electrochemical dissolution rather than mechanical contact, thereby avoiding the introduction of mechanical stress that would alter the structure being examined.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If samples are physically removed from conductive materials and brought to a material analysis lab for preparation steps including mechanical and chemical etching, then structure analysis can be performed, but the process is laborious, time consuming, and adds stress to the metal

Engineering Contradiction:
Improvestructure analysis capabilityVSAvoidtesting process duration
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges the material removal function and the structure revelation function into a single integrated process. The charged electrolytic jet both removes material and simultaneously reveals the microstructure, eliminating the need for separate mechanical polishing and chemical etching steps that are traditionally performed in a lab setting.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the essential function of structure revelation from the complex traditional workflow of sample removal, mechanical polishing, and chemical etching. By using the electrolytic jet to directly expose the microstructure in situ, the invention removes unnecessary preparatory steps and transfers the analysis capability to the production environment.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If the upper surface of conductive material is removed by slicing or grinding to reveal structure, then the metal can be polished and etched for imaging, but this process is laborious, time consuming, and limited to flat pieces of metal

Engineering Contradiction:
Improvesurface structure visibilityVSAvoidprocess simplicity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent replaces mechanical slicing, grinding, and polishing operations with an electrochemical dissolution process using a charged electrolytic jet. This substitution eliminates the need for complex mechanical preparation steps and enables the examination of complex geometries that cannot be processed by traditional mechanical means.

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

4Measurement precision

If serial sectioning is performed to determine three dimensional structure, then images can be combined to produce a 3-dimensional representation, but complex measurement techniques are required to correctly position the images

Engineering Contradiction:
Improvethree dimensional structure determinationVSAvoidmeasurement technique complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical measurement and positioning systems with a controlled electrolytic dissolution process. By using the charged electrolytic jet to systematically remove material layer by layer and simultaneously capture images, the invention simplifies the 3D reconstruction process and eliminates the need for complex measurement techniques to position images correctly.

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