Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pixels emitting light in different wavelength ranges are arranged in a specific pattern, then image generation capability is improved, but device size increases
Solution Approach 1:
The patent introduces a third dimension (vertical stacking) by placing the optical part above the pixel array, allowing optical signals to be reflected and directed without increasing the horizontal footprint. This enables compact pixel arrangement while maintaining image generation capability through spatial separation in the vertical direction.
Solution Approach 2:
The optical part is divided into multiple regions corresponding to different wavelength ranges, with each region having specific reflective properties. This segmentation allows different pixels emitting different wavelengths to be efficiently managed and directed to appropriate sensor regions without requiring larger device area.
2Reliability
If pixels are arranged with spacing for optical signal management, then optical signal quality is improved, but pixel density decreases
Solution Approach 1:
By utilizing the vertical dimension with the optical part positioned above the pixel array, the patent eliminates the need for large horizontal spacing between pixels. Optical signals can be managed and directed through the vertical optical path, allowing pixels to be densely packed while maintaining signal quality through the reflective optical design.
Solution Approach 2:
The optical part serves multiple functions: it reflects optical signals from different wavelength ranges, directs them to appropriate sensor regions, and enables compact pixel arrangement. This multi-functionality allows the system to maintain high pixel density while ensuring proper optical signal management through a single integrated component.
