Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple projectors with independent light sources are used in a tiled arrangement, then the coverage area and projection capacity are improved, but brightness and colorimetry mismatches become more apparent, degrading image quality
Solution Approach 1:
The patent combines multiple light sources into a single centralized light source that serves all projectors in the tiled arrangement. This eliminates the brightness and colorimetry mismatches that occur with independent light sources, as all projectors now receive light from the same source with consistent characteristics. The merged light distribution system ensures uniformity across the entire projection area.
Solution Approach 2:
The patent introduces a light distribution system as an intermediary between the centralized light source and the multiple projectors. This intermediary system includes light guides and switching mechanisms that evenly distribute the light from the single source to multiple projectors, ensuring consistent brightness and colorimetry across all projection surfaces while maintaining the ability to serve large areas.
2Adaptability or versatility
If each projector has its own light source, then the independence and operational flexibility of each projector are improved, but the difficulty of matching brightness and contrast across projectors increases, impacting overall image quality
Solution Approach 1:
The patent implements a dynamic light distribution system that can switch and adjust light allocation to different projectors in real-time. The system includes switching mechanisms that can dynamically route light from the centralized source to different projectors based on operational requirements, maintaining both centralization for consistency and flexibility for adaptability.
3Manufacturing precision
If a single centralized light source is used to serve multiple projectors, then brightness and colorimetry consistency are improved, but the complexity of the light distribution system increases
Solution Approach 1:
The patent segments the light distribution system into modular components including separate light guides for each projector, individual switching mechanisms, and distinct distribution channels. This segmentation allows the complex function of serving multiple projectors from a single source to be divided into manageable, independent modules that can be installed and maintained separately, reducing overall system complexity.

Data Source
AI summary
A system and apparatus for dynamically distributing light are provided. The apparatus includes a source conduit configured to collect light from a light source and transmit the collected light for emission towards an optical switch. The optical switch is moveable between several discrete resting positions, each corresponding to a different one of a plurality of projector conduits. In each resting position, the optical switch directs light from the source conduit to a corresponding projector conduit. Each projector conduit receives the directed light from the optical switch and transmits the light to a corresponding one of a plurality of projectors. The optical switch is also configured to rest at each of the resting positions for respective portions of a given period of time, to regulate what amount of the light emitted by the source conduit during the period of time is received by each projector conduit.
