Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high-intensity light sources are used to meet projection system requirements, then illumination intensity is improved, but device size increases making it unsuitable for space-constrained applications
Solution Approach 1:
The illumination source is divided into multiple separate illumination devices (first through sixth illumination devices) that can be independently arranged and optimized. Each device contributes to the overall light intensity while allowing compact packaging through distributed arrangement on opposite surfaces of the housing.
Solution Approach 2:
Illumination devices are arranged on both the first surface and second surface (opposite surfaces) of the housing, utilizing three-dimensional space efficiently. This multi-surface arrangement allows compact integration while maintaining high total light output by distributing sources across multiple spatial planes.
2Illumination intensity
If multiple illumination devices are arranged to produce different colors, then color diversity and light intensity are improved, but device complexity increases
Solution Approach 1:
The illumination system is segmented into multiple devices, each potentially emitting different colors (first color, second color, third color). This segmentation allows independent optimization of each device while achieving combined high-intensity multi-color output through simple spatial arrangement.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical support, defines the spatial arrangement of illumination devices on opposite surfaces, and facilitates optical combining. This multi-functional design reduces overall system complexity despite the presence of multiple illumination devices.

AI summary
An apparatus includes a housing having opposing first and second surfaces. A first illumination device produces first light, a second illumination device produces second light, and a third illumination device produces third light. The first, second, and third illumination devices are arranged along the first surface. The first light has a first color, the second light has a second color, and the third light has a third color. The first color is different than the second color and the third color, and the second color is different than the third color. A fourth illumination device produces fourth light, a fifth illumination device produces fifth light, and a sixth illumination device produces sixth light. The fourth, fifth, and sixth illumination devices are arranged along the second surface. The fourth light has the first color, the fifth light has the second color, and the sixth light has the third color.
