Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional projectors are used to create distributed manifestations, then the system can display visual content, but signal saturation occurs and sensor operation exceeds dynamic range
Solution Approach 1:
The patent segments the visual display into multiple discrete light sources (LEDs) distributed across the environment. Each LED operates independently at lower intensity levels, preventing sensor saturation while collectively providing comprehensive spatial coverage. This segmentation allows the system to maintain visual display quality without exceeding sensor dynamic range.
Solution Approach 2:
The patent implements local quality by varying the intensity and activation state of individual LEDs based on their specific spatial locations and viewing conditions. Each light source is independently controlled to provide optimal local illumination without causing overall system signal saturation, enabling reliable sensor operation across the entire distributed display.
2Device complexity
If single projector systems are used, then the setup is simple, but line-of-sight obstructions create gaps in the visual experience
Solution Approach 1:
The patent divides the single projector system into multiple distributed LED sources positioned throughout the environment. This segmentation eliminates line-of-sight obstructions by providing multiple viewing paths to different spatial zones, ensuring continuous visual experience without gaps while maintaining manageable system complexity through modular deployment.
Solution Approach 2:
The patent transitions from a single-point projector to a multi-dimensional distributed array of light sources. By adding spatial distribution across multiple dimensions, the system overcomes line-of-sight limitations and creates comprehensive coverage, transforming the visual display from a centralized projection to a distributed spatial manifestation.
3Reliability
If distributed light sources are used to cover all areas, then spatial continuity is achieved, but the number of components increases
Solution Approach 1:
The patent implements universality by designing each distributed LED unit to serve multiple functions: spatial positioning, visual display, and potential interaction capabilities. This multi-functionality reduces the need for separate specialized components, achieving comprehensive spatial coverage with a standardized modular unit that simplifies overall system complexity.
Solution Approach 2:
The patent utilizes parameter changes by varying the intensity, color, and activation state of individual LEDs based on spatial location and viewing conditions. This dynamic parameter adjustment allows the system to achieve continuous spatial coverage with fewer active components at any given time, effectively managing the number of simultaneously operating light sources while maintaining visual continuity.

Data Source
AI summary
Systems and method for distributed manifestation are described. One such system may comprise a data generator configured to generate data sets comprising state data and corresponding spatial coordinate data. The data sets may be encoded so as to allow a receiving unit to operate within its dynamic range. The data sets may be transmitted, using one or more projectors, in the direction of a target area. The target area may comprise a first area and a second area. In some circumstances, the first and second areas do not overlap in space. In other circumstances, the first and the second areas may overlap, at least partially. The system may further comprise a processor configured to provide a synchronization sequence for synchronizing the projectors to one another.
