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 patent combines multiple light sources (first light source emitting first wavelength, second light source emitting second wavelength, third light source emitting third wavelength) into a single integrated module. The light-splitting elements and reflection layers merge these separate light sources into a unified structure that outputs combined light, achieving high brightness while managing complexity through integration.
Solution Approach 2:
The patent divides the light generation function into separate segments: first light source, second light source, and third light source, each emitting different wavelengths. These segmented light sources are then processed through light-splitting elements and reflection layers to combine them effectively, allowing independent optimization of each light source while achieving superior overall brightness.
2Loss of energy
If light-splitting elements are strategically positioned to optimize optical paths, then light utilization is improved, but device complexity increases
Solution Approach 1:
The patent introduces light-splitting elements as intermediary components between the light sources and the output. These light-splitting elements mediate the optical paths by selectively transmitting and reflecting specific wavelengths, optimizing light utilization. The reflection layers also serve as intermediaries to redirect light toward the output, minimizing energy loss.
Solution Approach 2:
The patent optimizes optical paths by introducing spatial dimensionality through strategically positioned light-splitting elements. These elements are arranged in specific spatial configurations that create optimized light pathways, utilizing three-dimensional space to improve light utilization efficiency while managing the added complexity through structured arrangement.

AI summary
A light source module includes a first light-splitting element, a second light-splitting element, a first light source, a second light source and a third light source. The first light source emits a first light having a first wavelength to the first light-splitting element in a first optical path direction. The second light source emits a second light having the first wavelength to the first light-splitting element in a second optical path direction perpendicular to the first optical path direction. The third light source emits a third light having a second wavelength to the first and second light-splitting elements in a third optical path direction opposite to the second optical path direction, and the second wavelength is different from the first wavelength. The first light source and the second light source include reflection layers configured to reflect light having the first wavelength.
