Rotating Display Grating for Naked-Eye 3D Viewing Position Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies limit the versatility of 3D viewing experiences due to fixed positioning requirements, which restrict the application of naked-eye 3D displays and user experience.
Innovation Solution
An adjusting device with a supporting portion and a rotatable portion embedded in a groove, capable of moving the display panel or grating to align with the viewer's eye position, allowing for dynamic adjustment of the light exit direction to achieve optimal 3D display at various positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel or grating is fixed in position, then the structure is simple and stable, but the 3D viewing experience is limited to specific positions only
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed display panel or grating into a movable component. The adjusting device includes a rotatable portion that can rotate within a groove, enabling the display panel or grating to move dynamically. This allows the system to adapt to different viewing positions while maintaining a relatively simple structural design, thus resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If the display panel or grating is made movable to adjust viewing positions, then the versatility of 3D viewing is improved, but the structural complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjusting device into distinct functional components: a supporting portion with a groove and a separate rotatable portion. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while enabling the desired mobility and adaptability for viewing position adjustment.
Solution Approach 2:
The rotatable portion is embedded within the groove of the supporting portion, creating a nested structure. This nesting approach allows the movable component to be integrated into the supporting structure without adding significant external complexity, achieving both adaptability and structural efficiency.
3Adaptability or versatility
If a complex adjusting mechanism is used to enable viewing from multiple positions, then the adaptability is improved, but the device becomes more complicated and harder to control
Solution Approach 1:
The patent replaces complex mechanical adjusting mechanisms with a simplified rotational system. The rotatable portion rotates within a groove to achieve position adjustment, which is mechanically simpler and easier to control than traditional multi-component adjusting mechanisms. This substitution maintains multi-position viewing capability while significantly improving ease of operation.
