Engineering Contradiction Analysis
1Weight of moving object
If portable Raman systems are used, then portability is improved, but measurement accuracy and reliability deteriorate
Solution Approach 1:
The patent combines multiple optical sources and spectrometers into a single portable Raman system, integrating their functions through a common optical path and control system. This merging allows the compact device to leverage the combined capabilities of multiple components, achieving both portability and measurement accuracy by consolidating functionality rather than relying on a single simplified component.
2Device complexity
If fixed sample configuration is used, then device simplicity is improved, but measurement versatility deteriorates
Solution Approach 1:
The patent implements dynamic sample configuration capabilities within the portable Raman system, allowing the optical path, sample holders, and measurement parameters to be adjusted and reconfigured during operation. This dynamic adaptability enables the system to handle various sample types and measurement requirements while maintaining a relatively simple overall device structure through programmable control.
3Ease of operation
If traditional vials are used, then sample holding capability is improved, but sample volume requirement increases
Solution Approach 1:
The patent modifies the traditional vial design by changing key parameters such as volume, shape, and optical properties to create optimized sample holders for portable Raman spectroscopy. These parameter changes enable the use of smaller sample volumes while maintaining ease of operation and compatibility with the portable device's optical system.
