Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Raman spectrum data is displayed with Raman shift as the horizontal axis, then the Raman spectroscopic analysis can be performed, but the existing infrared spectroscopy software cannot process it
Solution Approach 1:
The patent transforms the horizontal axis parameter from Raman shift (non-uniform intervals) to wave number (uniform intervals) through mathematical conversion. This parameter change allows Raman spectrum data to be processed by infrared spectroscopy software without requiring separate processing systems, thereby resolving the software compatibility issue while maintaining data integrity
Solution Approach 2:
By converting Raman spectrum data to the wave number domain with uniform intervals, the patent enables a single software system to handle both infrared and Raman spectroscopic analysis. This universal approach eliminates the need for separate processing software for different spectral types, achieving multi-functionality in the data processing system
2Ease of operation
If Raman spectrum data is converted to equal interval wave number data, then the same software can be used for both infrared and Raman analysis, but additional data conversion processing is required
Solution Approach 1:
The patent performs the wave number conversion and equal-interval transformation as a preliminary step before displaying or analyzing the Raman spectrum data. By pre-processing the data into a standardized format, the system simplifies subsequent operations and allows users to interact with uniformly spaced spectral data, improving ease of operation despite the added conversion step
3Device complexity
If infrared spectrum analysis software is used for Raman spectrum analysis without conversion, then software complexity is reduced, but processing capability is lost
Solution Approach 1:
The patent applies parameter transformation by converting the independent variable from Raman shift to wave number, and ensures uniform data intervals. This mathematical transformation allows existing infrared analysis software to process Raman data without requiring separate processing algorithms, thereby maintaining software simplicity while expanding analysis capability to include both infrared and Raman spectroscopy
