Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visual comparison to a color grading system is used, then plasma grading can be performed with simple equipment, but the process becomes labor-intensive and subjective leading to inconsistent results
Solution Approach 1:
The patent replaces the manual visual inspection system with an optical measurement system consisting of a light source, spectrometer, and automated analysis. This substitution eliminates human subjectivity and labor intensity while providing objective, precise plasma grading based on spectral wavelength measurements, directly resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The patent introduces an optical spectrometer as an intermediary device between the plasma sample and the grading determination. This intermediary objectively measures the plasma's light reflection spectrum and provides quantitative data for automated grading, eliminating the need for manual visual comparison while maintaining operational simplicity through computerized analysis
2Productivity
If manual plasma grading is performed, then equipment requirements are minimal, but labor resources and time are significantly consumed
Solution Approach 1:
The patent implements a self-service automated system where the optical grading apparatus independently performs plasma analysis without requiring manual intervention. The system automatically illuminates the plasma, captures spectral data, processes the information, and determines the grade, thereby eliminating labor consumption while significantly improving grading throughput and productivity
Solution Approach 2:
The manual labor-intensive process is replaced by an automated optical measurement and analysis system. The spectrometer and computer automatically perform all grading operations, reducing both labor resources and time consumption while increasing productivity through rapid, sequential analysis of multiple plasma samples

Implementation Method 1
emitting, from a broadband light source, light having wavelengths in a visible range and directing the emitted light to a vessel at an incidence angle. The method also includes receiving, at an optical spectrometer, a reflected light portion of the emitted light
Implementation Method 2
analyzing, with the optical spectrometer, at least a portion of the received reflected light to determine a main wavelength of the received reflected light
Data Source
AI summary
An optical plasma grading system includes a broadband light source configured to emit light having wavelengths in a visible spectrum, an optical spectrometer configured to receive a reflected portion of the emitted light and analyze at least a portion of the received, reflected light to determine a main wavelength of the portion of the received reflected light, and a controller operably connected to the optical spectrometer, the controller configured to determine a plasma grade of the plasma based at least upon the main wavelength of the plasma.
