Solution Overview

Problem

Infrared spectroscopy is not optimal for analyzing inorganic substances like metals, requiring users to estimate the component and choose between different analysis methods, which is cumbersome and may lead to inappropriate analysis.

Innovation Solution

A composite analysis apparatus and method that combines infrared spectroscopic analysis and laser-induced breakdown spectroscopy (LIBS), where infrared spectroscopic analysis is conducted before LIBS, using a sample holder, infrared and laser light sources, a spectroscope, and a control device to identify components based on both types of analysis data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If infrared spectroscopy is used for analysis, then organic substances can be analyzed effectively, but inorganic substances such as metals cannot be analyzed optimally

Engineering Contradiction:
Improveanalysis method applicabilityVSAvoidanalysis accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines infrared spectroscopy and LIBS into a single composite analysis apparatus that can perform both types of analysis. The apparatus integrates an infrared light source, infrared detector, laser light source, and spectroscope, allowing users to conduct both organic and inorganic substance analysis without switching between separate instruments, thereby resolving the contradiction between versatility and analysis accuracy for different substance types.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The composite analysis apparatus is designed to perform multiple functions: it can conduct infrared spectroscopic analysis for organic substances and LIBS analysis for inorganic substances using the same device. This multi-functionality eliminates the need for users to estimate the component type and choose between different analysis methods, providing universal adaptability across different substance types while maintaining reliable analysis accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If users estimate the component and choose analysis method, then analysis can be performed, but user effort increases and inappropriate analysis may occur

Engineering Contradiction:
Improveuser effortVSAvoidanalysis appropriateness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

By making the apparatus universal and capable of performing both infrared spectroscopy and LIBS, the system eliminates the need for users to estimate components and select analysis methods. The apparatus can handle both organic and inorganic substances, greatly simplifying operation while ensuring appropriate analysis is performed for any substance type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs infrared spectroscopic analysis first as a preliminary step before conducting LIBS analysis. This preliminary action allows the system to gather initial information about the sample, and based on that data, determine whether further LIBS analysis is needed, thereby automating the decision-making process and reducing user effort while maintaining analysis appropriateness.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If LIBS analysis is conducted first, then inorganic substances can be analyzed, but subsequent infrared spectroscopic analysis becomes ineffective due to sample damage

Engineering Contradiction:
Improveanalysis effectivenessVSAvoidsample integrity
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The system performs infrared spectroscopic analysis as a preliminary step before conducting LIBS analysis. This sequencing ensures that the non-destructive infrared analysis is completed first when the sample is still intact, followed by the more intense LIBS analysis. This resolves the contradiction by maintaining sample integrity for the first analysis while still enabling effective inorganic substance analysis through the subsequent LIBS step.

Inventive Principle:
Principle #10Preliminary action

AI summary

An analysis method is performed in a composite analysis apparatus in which infrared spectroscopic analysis by infrared spectroscopy and LIBS analysis by laser-induced breakdown spectroscopy can be performed on a sample. The analysis method includes conducting infrared spectroscopic analysis by irradiating the sample with infrared rays, conducting LIBS analysis by irradiating the sample with laser beams, and identifying a component in the sample based on first analysis data obtained by infrared spectroscopic analysis and second analysis data obtained by LIBS analysis. The conducting infrared spectroscopic analysis is performed before the conducting LIBS analysis.
