Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional micro Raman spectrometer design is used, then measurement capability is achieved, but device complexity and difficulty of adjustment increase
Solution Approach 1:
The system is divided into modular components: a laser module (with optional adjustment mechanism), a spectrometer module, and a control unit. This segmentation allows independent optimization and simplifies adjustment of each module rather than adjusting the entire system at once.
Solution Approach 2:
The laser module is designed to be universally applicable with the ability to select different laser wavelengths and adjust axis/orientation parameters. This multi-functionality reduces the need for multiple specialized components, simplifying the overall system setup.
2Adaptability or versatility
If fixed laser wavelength is used, then system simplicity is maintained, but adaptability to different measurement needs decreases
Solution Approach 1:
The laser module incorporates dynamic adjustability for axis and orientation parameters, allowing the system to adapt to different measurement requirements. This dynamic capability enables wavelength selection and positioning adjustment without requiring multiple fixed systems.
Solution Approach 2:
The system allows changing of laser parameters (wavelength, axis position, orientation) to adapt to different measurement needs. By enabling parameter changes in the laser module, the system becomes versatile without requiring fundamentally different hardware configurations.
3Productivity
If manual adjustment of light path components is required, then measurement precision can be optimized, but operation time and complexity increase
Solution Approach 1:
The laser module comes pre-configured with adjustable axis and orientation mechanisms, allowing preliminary setup of the light path before actual measurement. This preliminary action reduces the time required during actual operation while maintaining alignment precision.
Solution Approach 2:
The system incorporates self-adjustment capabilities through the axis adjustment mechanism and orientation control, allowing the user to independently optimize the light path without requiring complex external alignment tools or procedures.

Function Achieved in This Case
Facilitates easy operation and adjustment of the light path, enhances applicability by allowing flexible wavelength selection, and enables efficient switching between measurement and observation modes, making the system more user-friendly and versatile.
Implementation Method 1
It relies on inelastic scattering, or Raman scattering, of monochromatic light, usually from a laser in the visible, near infrared, or near ultraviolet range. The laser light interacts with molecular vibrations, phonons or other excitations in the system, resulting in the energy of the laser photons being shifted up or down.
Implementation Method 2
The beam splitter is disposed on the path of the laser beam.
