Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional circuit board structure is used for image display, then electrical connection and component mounting are achieved, but 3D visual effect and light deflection capability are not provided
Solution Approach 1:
The light deflecting lens array is divided into multiple independent light deflecting units, each capable of deflecting light to specific viewing zones. This segmentation enables 3D visual effect while maintaining manageable structural complexity through modular design
Solution Approach 2:
The patent transitions from conventional 2D display to 3D display by introducing light deflection capability that directs images to multiple viewing zones simultaneously. This adds a spatial dimension to the display, creating 3D visual effect without requiring complete structural redesign
2Adaptability or versatility
If light deflecting lens array is added to create multiple viewing zones, then 3D visual effect is achieved, but image blinking and synchronization issues occur
Solution Approach 1:
The light deflecting units operate in a periodic manner, sequentially deflecting light to different viewing zones in a controlled time sequence. This periodic operation, synchronized with the display panel's image output, eliminates image blinking and ensures stable synchronization across multiple viewing zones
Solution Approach 2:
The system employs feedback control to synchronize the light deflection timing with the display panel's image output. By monitoring and adjusting the timing relationship between light deflection and image display, the system maintains reliable synchronization and prevents image blinking
3Adaptability or versatility
If liquid crystal units are used for light deflection, then flexible and adjustable light direction control is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The liquid crystal units utilize parameter changes in their refractive index properties to control light deflection direction. By adjusting electrical parameters applied to the liquid crystal units, the system achieves flexible light direction control without requiring extremely tight manufacturing tolerances on physical alignment
Solution Approach 2:
The patent replaces mechanical alignment adjustment mechanisms with electrical control of liquid crystal properties. Instead of requiring precise mechanical alignment during manufacturing, the system uses electrical signals to control the refractive index of liquid crystal units, achieving flexible light direction control with reduced manufacturing precision requirements
