Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple semiconductor components are arranged next to each other in an array to produce pixelated light sources, then the luminance can be increased, but the cooling becomes more difficult and manufacturing complexity increases
Solution Approach 1:
The patent segments the light source into multiple independently controllable output waveguides, each capable of emitting at different wavelengths. This segmentation allows independent cooling and control of each segment, reducing the overall cooling complexity while maintaining high luminance through the array of segments.
Solution Approach 2:
The patent introduces a distribution structure as an intermediary component that receives electromagnetic radiation from semiconductor components and distributes it to multiple output waveguides. This intermediary simplifies the cooling architecture by centralizing the heat management function while maintaining the benefits of multiple independent light sources.
2Illumination intensity
If multiple semiconductor components are arranged next to each other in an array, then the luminance can be increased, but the manufacturing precision requirements increase
Solution Approach 1:
The patent merges multiple semiconductor components into a single integrated structure where they are monolithically integrated on a substrate. This merging approach maintains the high luminance benefits of multiple light sources while significantly reducing manufacturing precision requirements, as the integrated structure is manufactured as one piece rather than requiring precise assembly of separate components.
Solution Approach 2:
The patent creates a universal platform where a single semiconductor component can serve multiple functions by distributing its output through the distribution structure to various output waveguides. This multi-functionality reduces the need for multiple specialized components, thereby reducing manufacturing precision requirements while maintaining high luminance.
3Ease of operation
If a distribution structure is used to distribute electromagnetic radiation to multiple output waveguides, then the control is simplified, but the device complexity increases
Solution Approach 1:
The distribution structure serves multiple functions simultaneously: it distributes electromagnetic radiation to multiple output waveguides, enables wavelength division multiplexing, and provides a platform for independent control of each output. This multi-functionality justifies the added structural complexity by delivering multiple control benefits from a single component.
Solution Approach 2:
The distribution structure acts as an intermediary that simplifies the control architecture by centralizing the radiation distribution function. Instead of requiring separate control mechanisms for each output waveguide, the single distribution structure mediates the control for all outputs, reducing the overall system complexity despite the added structural element.
4Measurement precision
If conversion structures are arranged downstream of each output waveguide, then the contrast ratio between neighboring conversion structures is increased, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the conversion structures into separate, independently manufacturable units arranged downstream of each output waveguide. This segmentation allows for precise alignment and high contrast ratio between neighboring conversion structures while reducing manufacturing complexity through modular assembly rather than monolithic integration.
