Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional spectroscopic methods are used to analyze inhomogeneous objects, then the measurement process is simple, but the measurement precision deteriorates due to averaging out local variations
Solution Approach 1:
The patent combines a spectrometer device with an imaging device into a unified measurement system. The spectrometer captures spectral data while the imaging device captures spatial information, and both data types are integrated through evaluation units to produce spatially resolved chemical composition maps. This merging resolves the contradiction by achieving high measurement precision through multi-parameter data fusion while maintaining manageable device complexity through modular integration.
Solution Approach 2:
The patent transitions from conventional single-point or bulk spectroscopic measurement to spatially resolved spectroscopy by adding a spatial dimension. The imaging device provides spatial coordinates while the spectrometer provides spectral information, creating a two-dimensional chemical composition map. This dimensional expansion enables detection of local variations inhomogeneities without requiring complex multi-component instruments, as the spatial dimension compensates for the simplification.
2Loss of information
If spectroscopic data is acquired without spatial information, then the device complexity is low, but the loss of information increases due to averaging effects
Solution Approach 1:
The patent merges spectral data acquisition with spatial information capture by integrating a spectrometer and imaging device. The evaluation units process both data types to reconstruct spatially resolved chemical composition information, preventing information loss about local variations. This integration achieves high information retention while maintaining relatively simple device architecture through modular component combination.
3Measurement precision
If conventional spectroscopic methods are used, then the ease of operation is high, but the measurement precision deteriorates for inhomogeneous samples
Solution Approach 1:
The patent implements self-service through automated evaluation units that process and correlate spectral and spatial data automatically. The system autonomously generates chemical composition maps and identifies regions of interest without requiring manual intervention. This automation maintains ease of operation while significantly improving measurement precision for inhomogeneous samples by consistently applying complex data processing algorithms.
Solution Approach 2:
The patent incorporates feedback mechanisms where the evaluation units continuously process spectral and spatial data to refine chemical composition mappings. The system uses the spatial information from the imaging device to guide and interpret spectral measurements, creating an iterative feedback loop that enhances precision while maintaining operational simplicity through automated data fusion.
