Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate digital camera is used to capture images of the analyte, then the imaging function is achieved, but the operation time and user effort increase
Solution Approach 1:
The patent combines the imaging function and analysis function into a single integrated device. The imaging section and analysis section share common components (light source, optical path, detector) to capture both reflection light for imaging and plasma light for analysis simultaneously, eliminating the need for separate digital camera operation and reducing total operation time.
Solution Approach 2:
The device performs multiple functions using shared components. The same optical system and detector used for LIBS analysis also capture reflection light for imaging, allowing the device to serve both imaging and analytical purposes without requiring additional specialized equipment or increasing operation time.
2Ease of operation
If a separate digital camera is used for imaging, then the analyte can be observed, but the device complexity increases
Solution Approach 1:
The imaging section and analysis section are merged into a single integrated system with shared optical components and a common detector. This consolidation reduces the number of separate devices needed while maintaining both imaging and analysis capabilities, thereby reducing overall device complexity despite the multi-functional requirement.
3Productivity
If imaging and analysis are performed separately, then each function can be optimized, but the productivity decreases
Solution Approach 1:
The device enables continuous operation by simultaneously capturing reflection light for imaging and plasma light for analysis during the laser irradiation process. Both functions are performed in one continuous operation without interruption or sequential execution, maximizing productivity and minimizing total operation time.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integration saves time and effort required for imaging, improves the usability of the analysis device by allowing simultaneous observation and analysis, and enhances user experience by providing a direct visual correlation between analysis results and the analyte.
Implementation Method 1
an imaging section which receives reflection light reflected by the analyte placed on the placement stage
Implementation Method 2
a laser light emitter which emits laser light to the analyte; a collection head which collects plasma light generated in the analyte as the analyte is irradiated with the laser light
Implementation Method 3
a detector which receives the plasma light generated in the analyte and collected by the collection head, and generates an intensity distribution spectrum that is an intensity distribution of the plasma light for each wavelength
Data Source
AI summary
It is possible to save time and effort required for imaging of an analysis point and to improve usability of an analysis device. An analysis and observation device as a laser-induced breakdown spectroscope includes: a first camera, an electromagnetic wave emitter that emits laser light to a sample; a reflective object lens that collects plasma light generated in the sample; first and second detectors that generate intensity distribution spectra; and a processor. The processor controls the first camera in response to reception of a start trigger signal to generate a pre-irradiation image that is an image before the sample is irradiated with the laser light, and controls the electromagnetic wave emitter after controlling the first camera to emit the laser light to the sample.
