Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If direct radiation from LED light sources is used to illuminate graphic openings, then the structure is simple, but the light output is non-uniform and aesthetically displeasing
Solution Approach 1:
A photon recycling cavity acts as an intermediary between the LED light source and the graphic opening. The cavity contains reflective surfaces that mediate the light path, converting direct radiation into indirect, uniformly distributed illumination that exits through the graphic openings in a visually pleasing manner.
Solution Approach 2:
The patent transforms the light distribution from a direct one-dimensional path to a multi-dimensional indirect path within the photon recycling cavity. By introducing spatial complexity through reflective surfaces and cavity geometry, the light is redistributed uniformly across multiple dimensions before exiting the graphic openings.
2Illumination intensity
If uniform light distribution is achieved through traditional methods, then aesthetic quality improves, but manufacturing cost and complexity increase
Solution Approach 1:
The photon recycling cavity is designed to utilize and recycle photons that would otherwise be lost or wasted. The reflective surfaces within the cavity cause photons to bounce and redistribute, allowing the system to self-regulate and achieve uniform light distribution without requiring additional expensive optical components or complex manufacturing processes.
Solution Approach 2:
The system recovers photons that would normally be discarded or lost within the housing structure. By incorporating reflective surfaces in the photon recycling cavity, previously wasted light is captured and redirected toward the graphic openings, achieving uniform illumination while minimizing material usage and manufacturing cost.
3Adaptability or versatility
If static display configurations are used, then manufacturing is simpler, but adaptability and dynamic lighting capabilities are reduced
Solution Approach 1:
The display is divided into multiple independent segments or modules, each containing its own photon recycling cavity and graphic openings. This segmentation allows individual sections to be controlled independently, enabling dynamic lighting patterns, animations, and adaptive responses to different operational conditions while maintaining the uniform illumination benefits of the photon recycling principle.
Solution Approach 2:
The patent transitions from static to dynamic lighting by enabling independent control of different display segments. The segmented architecture allows the system to adapt its lighting patterns, intensity, and timing dynamically, providing versatility for various applications such as sequential lighting, animations, and responsive displays while maintaining the underlying photon recycling mechanism in each segment.

AI summary
A segmented display includes a first housing portion having graphic openings therein, a second housing portion spaced apart from the first housing portion and a first circuit board comprising a plurality of light emitting diodes (LEDs). The first circuit board is disposed between the first housing portion and the second housing portion. A first side wall and a second side wall are spaced apart from the first side wall. The first side wall and the second side wall define a plurality of photon recycling cavities in a sequence wherein adjacent photon recycling cavities having a shared end wall. At least one of the LED is disposed in each of the photon recycling cavities. Each LED is associated with an optical element redirecting light within the associated cavity so that light from the light emitting diode is indirectly communicated through the graphic opening after reflecting within the photon recycling cavity.
