Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lenticular lenses are used to achieve three-dimensional image recognition, then the device can provide depth perception through parallax, but the device size increases and visual stress occurs due to mismatched focusing points and sight intersection positions
Solution Approach 1:
The display surface is divided into multiple division regions, with each region corresponding to a specific lens. This segmentation allows the device to achieve three-dimensional imaging functionality through multiple smaller optical units rather than requiring a single large optical system, thereby reducing overall device size while maintaining depth perception capability
Solution Approach 2:
The patent transitions from traditional two-dimensional display to three-dimensional image recognition by utilizing the optical focusing dimension. By forming real or virtual images at different depths through lens focusing, the system adds a depth dimension to the display, enabling true three-dimensional perception without proportionally increasing device footprint
2Adaptability or versatility
If lenticular lenses focus light at specific points for three-dimensional imaging, then depth perception is achieved, but visual stress occurs due to mismatch between focusing points and sight intersection positions
Solution Approach 1:
The patent dynamically adjusts display parameters including the position of division regions, focal lengths of lenses, and image formation distances. By changing these optical parameters, the system can align the focusing points with the sight intersection position, thereby eliminating visual stress while maintaining depth perception capability
Solution Approach 2:
The system employs dynamic adjustment mechanisms that allow the focusing points and image formation positions to be adaptively changed based on viewing conditions. This dynamic capability enables the device to maintain optimal optical alignment between the lens focusing points and the user's sight intersection, preventing visual fatigue during prolonged use
3Measurement precision
If the display is divided into multiple regions with individual lenses for high-resolution three-dimensional imaging, then image quality improves, but device complexity increases
Solution Approach 1:
The patent combines multiple functional elements into an integrated structure where division regions, lenses, and image formation mechanisms are unified. By merging these components into a cohesive optical system, the device achieves high-resolution three-dimensional imaging capability while reducing the complexity that would arise from separate, independent components for each function
