Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual reality system uses separate two-dimensional display devices for left and right eyes, then three-dimensional image can be displayed, but the convergence point and focal distance do not match causing eye strain
Solution Approach 1:
The display system is segmented into multiple sub-pixels arranged in a matrix, with each sub-pixel corresponding to a specific lens. This segmentation allows independent control of light emission from each sub-pixel, enabling precise matching of convergence points and focal distances for different regions of the three-dimensional image, thereby reducing eye strain while maintaining 3D display capability
Solution Approach 2:
Different regions of the display have different optical properties tailored to their specific functions. Each sub-pixel region is optimized with specific lens combinations and light emission characteristics to achieve the correct convergence and focal properties for that local area, ensuring natural three-dimensional viewing across the entire display surface
2Ease of operation
If electronic hologram system records interference fringe, then three-dimensional image can be reproduced, but high technical hurdles prevent practical use
Solution Approach 1:
Instead of recording and reproducing complex interference fringes, the system creates a simplified copy of the three-dimensional information by displaying multiple two-dimensional images on sub-pixels that correspond to different lenses. Each lens refracts light from its corresponding sub-pixels to form virtual images at appropriate convergence points, achieving 3D reproduction without the complexity of holographic interference recording
Solution Approach 2:
The patent replaces the complex optical interference and diffraction mechanisms of electronic holography with a simpler geometric optics approach using arrays of lenses and controlled light emission from sub-pixels. This substitution maintains three-dimensional image reproduction capability while dramatically reducing technical complexity and enabling practical implementation
3Object-affected harmful factors
If pixel blocks and lens blocks are arranged in matrix with predetermined intervals, then natural three-dimensional image is displayed, but device structure becomes complex
Solution Approach 1:
The patent merges the pixel array and lens array into an integrated structure where sub-pixels and lenses are positioned in corresponding relationships within a unified matrix framework. This merging allows the complex matrix arrangement to function as a single coordinated system, where the predetermined intervals between sub-pixels and lenses work together to naturally form three-dimensional images without requiring separate complex positioning mechanisms
