Scratch Test Image-Force Synchronization Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing scratch test method is limited by the irreversibility of physical synchronization between scratch images and applied force, making it impossible to associate images with corresponding critical loads after the sample has been moved or changed, thus restricting analysis to only during the measurement process.
Innovation Solution
A method involving the recording and calibration of panoramic images synchronized with scratch parameters, allowing for visual analysis at any time without loss of resolution, using a digital image acquisition device and sensors connected to a computer program that maintains synchronization between scratch images and measurement curves, enabling association of force and image positions even after the scratch is no longer under the microscope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the scratch test is performed with visual inspection under a microscope during measurement, then the critical loads can be determined with physical synchronization between images and force, but the analysis cannot be performed after the sample has been moved or changed
Solution Approach 1:
The patent creates a digital copy of the scratch image and associates it with the corresponding force data through a synchronized recording system. This digital copy can be stored and analyzed later without requiring the physical sample to be present, thus enabling deferred analysis while maintaining measurement precision.
Solution Approach 2:
The patent performs preliminary synchronization and recording of image-position-force data during the scratch test before the sample is moved or removed. This preliminary action captures all necessary information in advance, allowing subsequent analysis to be conducted at any time without requiring the sample's physical presence.
2Reliability
If the scratch is analyzed immediately under the microscope, then the physical synchronization between image and force is maintained, but the sample must be physically present for analysis
Solution Approach 1:
The system creates a digital representation of the scratch image and its association with force data, replacing the need for physical sample presence. The digital copy maintains reliable image-force association while enabling flexible sample handling, as the analyzed data can be stored and accessed without the original sample.
Solution Approach 2:
The patent replaces the mechanical requirement of physically examining the sample under a microscope with a digital information system. The synchronized recording of image position and force data creates a virtual model that can be analyzed without mechanical interaction with the physical sample, thus improving ease of operation while maintaining reliability.
3Quantity of substance
If only a few images of the scratch are recorded during creation, then the data storage is minimal, but it is impossible to associate images with corresponding applied force for a posteriori analysis
Solution Approach 1:
The system performs preliminary synchronized recording of image position and force data during the scratch test. This preliminary action captures the correlation information in advance, allowing complete a posteriori analysis without requiring excessive storage of raw image data, thus balancing data storage requirements with information preservation.
Solution Approach 2:
The patent introduces an intermediary synchronization system that links image position data with force data through a common reference frame. This intermediary mechanism enables accurate image-force correlation without requiring storage of all raw data, as the synchronization metadata acts as a compact bridge between the two data types.

AI summary
The invention relates to a method for analyzing a scratch from a scratch test, employing a digital image acquisition device, a substrate and an indenter to apply a force to the substrate.The process includes the following steps: - determining the position of the start of the scratch relative to a reference position, - creating the scratch on the substrate using the indenter, recording the applied force and at least one measurement parameter, as a function of the displacement of the indenter on the substrate relative to the reference position, - acquiring and recording images of the entire significant part of the scratch, the position on the scratch corresponding to the recorded images being determined relative to the reference position, - synchronizing the recorded images, the applied force and the measurement parameter, as a function of the displacement of the indenter, - displaying the curves of the applied force and the measurement parameter as a function of the displacement of the indenter, and synchronously displaying an image of the significant part of the scratch, reconstructed from the recorded images.
