Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wavelength conversion units and light splitting units are added to generate multiple colors, then color diversity is improved, but module size increases
Solution Approach 1:
The patent combines multiple light sources (first light source and second light source) and their corresponding wavelength conversion units into a single integrated module. The light splitting units are strategically positioned to serve multiple wavelengths simultaneously, merging functions that would traditionally require separate components, thereby achieving color diversity without proportionally increasing module size
Solution Approach 2:
The light splitting units are designed with multi-functionality to handle multiple wavelengths (first wavelength, second wavelength, and third wavelength) in a single component. Each light splitting unit can selectively reflect or transmit different wavelengths, allowing one component to perform what would traditionally require multiple separate components, thus reducing overall module size while maintaining color diversity
2Adaptability or versatility
If multiple wavelength conversion units and light splitting units are used, then color generation capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the color generation function into distinct wavelength conversion units, each associated with a specific light source. The first wavelength conversion unit converts the first light to the second wavelength, while the second wavelength conversion unit converts the second light to the third wavelength. This segmentation allows for modular design and simplified control of each wavelength conversion process
Solution Approach 2:
Multiple light sources and their corresponding wavelength conversion units are merged into a single integrated module with shared optical paths. The light splitting units serve multiple wavelengths simultaneously, combining functions that would traditionally require separate systems, thereby reducing device complexity while maintaining color generation capability
