Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct excitation light irradiation is used to acquire sample images, then image acquisition is simple, but excitation light distribution becomes uneven causing uneven fluorescence images
Solution Approach 1:
The patent introduces a diffuser plate as an intermediary component between the light source and the sample. This diffuser plate scatters the excitation light to create uniform light distribution across the sample area, eliminating the unevenness caused by direct irradiation while maintaining the simplicity of the imaging system
Solution Approach 2:
The patent transitions from direct one-dimensional light path irradiation to two-dimensional diffuse light distribution by introducing the diffuser plate. This dimensional change in light propagation ensures uniform excitation across the entire sample area without complicating the overall system structure
2Measurement precision
If spectral imaging is used to acquire fluorescence information, then comprehensive sample analysis is achieved, but the system complexity increases
Solution Approach 1:
The patent employs a camera module that can capture images across multiple wavelength ranges (visible light, near-infrared, and ultraviolet) without requiring separate imaging systems for each range. This multi-functional approach enables comprehensive fluorescence spectral analysis while maintaining relatively simple system structure
Solution Approach 2:
The patent combines the excitation light source, diffuser plate, and multi-wavelength camera module into an integrated imaging system. By merging these components and their functions, the system achieves comprehensive spectral imaging capability without the complexity of multiple separate systems
3Loss of information
If multiple separate displays are used for spectra and images, then data is organized separately, but user convenience decreases
Solution Approach 1:
The patent merges the spectral data and image data into a single integrated display interface. The display unit simultaneously shows the fluorescence intensity spectrum and the corresponding sample image, allowing users to correlate spectral features with their spatial locations without switching between separate displays
Solution Approach 2:
The patent adds a spatial dimension to the spectral display by overlaying or juxtaposing the image with the spectrum. This dimensional integration allows users to visually correlate spectral characteristics with their corresponding spatial regions in the sample, enhancing both data organization and user convenience
