Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple white-light illumination is used, then the device complexity is reduced, but the color rendering and medical diagnostic capability deteriorate
Solution Approach 1:
The light source is segmented into multiple independent light sources (first light source with red, blue, and ultraviolet beams; second light source with green beam; third light source with yellow beam). Each light source emits a specific wavelength range, and beam splitters combine these segmented light beams to form composite illumination. This segmentation allows precise control over the spectral composition, achieving superior color rendering and medical diagnostic capability while maintaining manageable system complexity through modular design.
2Manufacturing precision
If multiple light sources with various colors are combined, then the color rendering is improved, but the device complexity increases
Solution Approach 1:
Beam splitters serve as intermediary optical elements that efficiently combine multiple light beams from different light sources. The first beam splitter combines the red, blue, and ultraviolet beams from the first light source, while the second beam splitter integrates these with the green beam from the second light source and yellow beam from the third light source. These intermediary beam splitters simplify the optical path design and reduce the complexity of directly combining multiple light sources, while achieving the desired multi-color composite illumination for superior color rendering.
3Manufacturing precision
If ultraviolet light is added to the light source, then the special optical properties and symptom detection capability are improved, but the device complexity increases
Solution Approach 1:
The ultraviolet beam from the first light source is merged with the visible light beams (red, blue, green, yellow) through beam splitters to form a composite light beam containing both ultraviolet and visible spectrum components. This merging approach integrates the ultraviolet functionality into the existing multi-color light source system without requiring separate ultraviolet illumination paths, thereby achieving special optical properties and enhanced symptom detection capability while minimizing the increase in device complexity through unified optical design.

AI summary
The present invention provides a light source module. The first light source forms the first beam from the second light source, the third light source, and the function of the first beam splitter. Then the second beam splitter reflects the first beam and transmits the fourth beam from the fourth light source for forming the mixed beam, which is received and projected by the optical processing device. Thereby, by using the high color rendering and special optical properties of the mixed beam, the applications and efficacy of the present invention can be improved.
