Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a grating structure is added to achieve naked eye 3D display effect, then the 3D display capability is improved, but the device complexity and production cost increase
Solution Approach 1:
The grating is divided into multiple independently controllable grating units that can be selectively activated. Each grating unit corresponds to specific pixel regions and can be controlled to be in transparent or opaque state, enabling the system to adapt to different resolutions without requiring a complete separate grating structure for each resolution level.
Solution Approach 2:
The grating units are made dynamically controllable through driving signal lines that can switch each grating unit between transparent and opaque states. This dynamic control allows the same grating structure to adapt to multiple resolutions by selectively activating appropriate grating units based on the current display resolution, eliminating the need for multiple fixed grating structures.
2Manufacturing precision
If separate grating structures are designed for different resolutions, then the display quality for each resolution is optimized, but the production cost and manufacturing complexity increase
Solution Approach 1:
A single grating structure is designed to serve multiple resolution requirements simultaneously. The grating comprises multiple grating units that can be selectively controlled to match different resolution levels, making one universal grating structure replace multiple resolution-specific gratings. This reduces manufacturing complexity and production costs while maintaining optimal display quality for each supported resolution.
3Ease of manufacture
If a fixed grating structure is used, then the manufacturing is simplified, but the compatibility with various resolutions is limited
Solution Approach 1:
The grating structure incorporates dynamically controllable grating units that can switch between transparent and opaque states based on driving signals. This dynamic capability allows a single manufactured grating structure to adapt to multiple resolutions, combining manufacturing simplicity with resolution versatility through electronic control rather than requiring multiple fixed structures.
Solution Approach 2:
The optical properties of grating units are changed through electrical control, allowing the same physical structure to present different optical configurations for different resolutions. By changing the state (transparent/opaque) of individual grating units via driving signals, the system achieves multi-resolution compatibility without manufacturing multiple gratings with different parameters.
4Reliability
If multiple grating structures are produced for different resolutions, then the display performance for each resolution is optimized, but the production time and resource consumption increase
Solution Approach 1:
One universal grating structure is manufactured to replace multiple resolution-specific gratings. This single structure can be configured through electronic control to optimize display performance for different resolutions, significantly reducing production time and resource consumption while maintaining the reliability and quality of display performance for each supported resolution.
