Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stereoscopic image display is implemented to display 3D images, then display quality and viewer experience are improved, but viewer discomfort and dizziness occur when watching for a long time
Solution Approach 1:
The patent implements a liquid crystal lens that can dynamically change its optical properties between different states (2D and 3D modes). The lens transitions from a flat state for 2D display to a curved state for 3D display, allowing the display system to adapt its optical characteristics in real-time based on the desired viewing mode, thereby providing high-quality 3D display when needed while enabling easy switching to 2D mode to prevent viewer discomfort
Solution Approach 2:
The patent changes the physical parameters of the liquid crystal lens by applying different voltages to control the refractive index and curvature of the lens. By varying the voltage applied to the liquid crystal layer, the lens can transition between different focal lengths and curvature states, enabling the display to switch between 2D and 3D modes and thereby managing viewer comfort while maintaining display quality
2Adaptability or versatility
If optical path control is implemented to enable both 2D and 3D display modes, then display versatility is improved, but device complexity increases
Solution Approach 1:
The liquid crystal lens serves multiple functions within a single component: it acts as a flat window element for 2D display mode and as a curved optical lens for 3D display mode. This multi-functional design eliminates the need for separate optical components for different display modes, achieving versatile 2D/3D switching capability while minimizing the increase in device complexity
Solution Approach 2:
The patent combines the functions of the liquid crystal layer and the lens structure into a single integrated liquid crystal lens assembly. By merging the light modulation function of the liquid crystal with the optical focusing function of the lens, the system achieves both 2D and 3D display capabilities through one unified component rather than requiring multiple separate elements
