Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources with different wavelengths are used, then brightness is improved, but device complexity increases
Solution Approach 1:
The light source module is segmented into multiple independent light sources (first light source emitting first wavelength, second light source emitting second wavelength, third light source emitting third wavelength) with separate optical paths. Each light source has its own reflective layer and light-splitting elements, allowing independent optimization while achieving high combined brightness output.
Solution Approach 2:
The patent introduces a third optical path dimension perpendicular to the first and second optical paths. The third light source emits light in a direction substantially perpendicular to the other two optical paths, utilizing three-dimensional spatial arrangement to combine multiple wavelengths without increasing planar complexity.
2Loss of energy
If light-splitting elements and reflective layers are added, then light utilization is improved, but manufacturing complexity increases
Solution Approach 1:
Light-splitting elements serve as intermediary components that selectively direct different wavelengths along specific optical paths. These elements mediate between the multiple light sources and the output, ensuring efficient wavelength separation and combination while maintaining a manageable manufacturing structure through standardized optical component interfaces.
3Illumination intensity
If multiple optical paths are implemented, then brightness combination is improved, but alignment precision requirements increase
Solution Approach 1:
The optical paths are arranged asymmetrically in three-dimensional space rather than symmetrically in a plane. The third optical path is positioned substantially perpendicular to the first and second optical paths, creating an asymmetric configuration that simplifies alignment by reducing sensitivity to planar misalignment while maintaining precise wavelength separation through the light-splitting elements.
