Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 2D pixel matrix is projected using conventional methods, then data can be transmitted to different locations, but voids appear between pixels leaving some audience members unable to receive the IR digital data stream
Solution Approach 1:
The patent transitions from a conventional 2D pixel matrix projection to a 3D volumetric light field approach. By using multiple light sources arranged in a three-dimensional configuration and employing optical elements to create light planes that intersect in space, the system fills the voids between traditional pixels and ensures continuous coverage throughout the projection volume, allowing receivers anywhere in the space to reliably receive data.
2Adaptability or versatility
If conventional projection methods are used, then manufacturing costs are reduced, but the full potential of the technology is not exploited for other applications
Solution Approach 1:
The patent creates a multi-functional lighting control system where the same 3D light field projection infrastructure can simultaneously perform multiple functions: transmitting control instructions to receivers, creating immersive visual displays, enabling interactive experiences, and supporting various application scenarios. The system's modular architecture with configurable light sources and optical elements allows it to adapt to different applications without requiring complete redesign, thereby achieving high versatility while maintaining reasonable manufacturing complexity.
3Area of stationary object
If light efficiency is enhanced using optical elements, then manufacturing costs increase, but coverage without voids is achieved
Solution Approach 1:
The patent divides the projection space into multiple overlapping light planes created by different light sources and optical elements. Each light source with its associated optical elements (lenses, prisms) creates a segmented portion of the overall light field. This segmentation allows for optimized local coverage in each segment while the overlapping regions ensure continuous coverage throughout the entire volume, reducing the need for expensive high-power single-source solutions and enabling cost-effective manufacturing through modular assembly.

Data Source
AI summary
Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels emitted by the pixel shaper assembly. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.
