A Raman photometer with a base module and expansion modules, featuring a semi-permeable interference filter that allows simultaneous capture of multiple components through parallel processing, reducing measurement time to under 60 seconds and enabling rapid analysis of complex samples by using a slot diaphragm for spatial filtering and band-pass filters for precise Raman band capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Raman photometers use sequential detection methods, then device complexity is reduced, but measurement time increases to minutes and sampling rate decreases
Solution Approach 1:
The device is divided into a base module and multiple expansion modules, each expansion module containing specific receiving devices for detecting different Raman bands. This segmentation enables parallel processing of multiple components simultaneously, increasing sampling rate from minutes to under 60 seconds while maintaining manageable device complexity through modular architecture
Solution Approach 2:
The invention transitions from sequential time-based detection to parallel spatial detection by arranging multiple receiving devices to detect different Raman bands simultaneously. This dimensional change from temporal to spatial processing enables rapid multi-component analysis without proportionally increasing overall device complexity
2Adaptability or versatility
If conventional Raman photometers lack modularity, then device complexity is reduced, but adaptability for different industrial processes decreases
Solution Approach 1:
The photometer is designed with a base module and detachable expansion modules, allowing flexible configuration for different applications. Users can select and combine specific expansion modules based on the components to be analyzed, providing high adaptability for different industrial processes while keeping the base module simple and standardized
Solution Approach 2:
The base module serves as a universal platform that can work with various expansion modules designed for different Raman band detections. This multi-functionality allows a single base module to support multiple analytical configurations, enhancing adaptability without requiring complex redesign for each application
