Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image segmentation is used to create left and right eye images, then three-dimensional visual effect is achieved, but device complexity and processing requirements increase
Solution Approach 1:
The patent replaces traditional mechanical image segmentation methods with a light field display approach that uses microlens arrays and spatial light modulation. Instead of digitally segmenting images into left and right views, the system optically synthesizes the light field to naturally provide depth perception and parallax effects, thereby achieving 3D visual effect without complex image processing
Solution Approach 2:
The display device integrates multiple functions into a single system: it simultaneously provides 2D display, 3D light field display, and adaptive focus adjustment capabilities. The microlens array structure enables the same hardware to deliver both conventional imaging and light field effects, eliminating the need for separate systems for different display modes
2Reliability
If water curtain is used to form virtual image, then three-dimensional display is achieved, but adaptability to different environments is reduced
Solution Approach 1:
The patent replaces the fragile and environment-sensitive water curtain with a solid-state microlens array structure that is durable, stable, and adaptable to various environments. The microlens array can be manufactured using standard optical fabrication techniques and maintains consistent performance across different temperature, humidity, and atmospheric conditions
Solution Approach 2:
The system allows dynamic adjustment of display parameters including focal depth, field of view, and image content through electronic control of the spatial light modulator and microlens array configuration. This enables adaptation to different viewing conditions and user preferences without changing the physical structure or environmental requirements
3Measurement precision
If multiple image-capture devices are used to capture color and depth images, then image quality is improved, but device complexity increases
Solution Approach 1:
The patent combines color imaging and depth sensing capabilities into integrated capture modules, where multiple sensors and processing functions are merged into unified devices. The system processes color and depth information simultaneously through coordinated sensors and algorithms, reducing the number of separate devices needed while maintaining high image quality
Solution Approach 2:
The patent introduces computational processing and image fusion algorithms as intermediaries that combine data from multiple sensors (color cameras, depth sensors, infrared sensors) into unified high-quality color-depth images. These computational intermediaries extract and integrate useful information from various sensor inputs, achieving superior image quality without requiring a proportional increase in physical devices
