Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple emission regions of different sizes are used to create autostereoscopic zones, then the radiation characteristics and three-dimensional image quality are improved, but the device complexity increases due to the need for multiple independently controllable light sources and precise spatial arrangement
Solution Approach 1:
The emission surface is divided into multiple emission regions (first emission regions and second emission regions) of different sizes and arrangements. These regions are independently controllable and emit light into different spatial zones to create autostereoscopic display effects without requiring additional optical aids.
Solution Approach 2:
Different emission regions have different sizes and light emission characteristics tailored to their specific functions. First emission regions and second emission regions are configured with different dimensions to create distinct zones with specific radiation patterns, optimizing the three-dimensional image quality for different viewing positions.
2Illumination intensity
If first and second emission regions are arranged in a specific pattern with precise spacing, then the optical properties and zone definition are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The emission regions are arranged in an asymmetric pattern where first emission regions and second emission regions have different sizes and positions. This asymmetric arrangement creates distinct optical zones with specific radiation characteristics, improving the three-dimensional display effect while providing tolerance in manufacturing through the design's inherent robustness.
3Adaptability or versatility
If independently controllable emission regions are implemented to adjust color and luminance, then the adaptability and color control are improved, but the device complexity and control system requirements increase
Solution Approach 1:
Each emission region is independently controllable, allowing dynamic adjustment of color location and luminance for different regions. This enables real-time modification of the displayed image's three-dimensional characteristics, color properties, and brightness distribution without requiring physical reconfiguration of the device.
