Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional single panel method is used for auto-stereoscopic 3D display, then the display can be implemented with a single panel structure, but it becomes difficult to implement large-sized displays with high resolution
Solution Approach 1:
The display system is divided into multiple independent light source units, each capable of emitting light for specific viewpoint images. This segmentation allows the system to maintain high viewpoint resolution while enabling large-sized displays by combining multiple units, resolving the contradiction between single panel ease of manufacture and manufacturing precision for large displays.
Solution Approach 2:
The patent transitions from conventional 2D panel arrangements to a 3D spatial arrangement of multiple light source units at different positions and heights. This dimensional change enables large-sized displays to achieve high viewpoint resolution by utilizing spatial separation of light sources for different viewpoints, rather than relying solely on panel density.
2Manufacturing precision
If point light sources are densely arranged to maintain high resolution, then viewpoint resolution is improved, but crosstalk between adjacent light sources increases
Solution Approach 1:
Each light source unit is designed with specific optical properties and positioning optimized for its local viewpoint function. The patent employs individual control and optical isolation for each light source unit, allowing dense arrangement while maintaining low crosstalk through localized optimization of each unit's optical characteristics and spatial positioning.
Solution Approach 2:
The patent introduces optical isolation mechanisms and precise positioning systems as intermediaries between adjacent light source units. These intermediaries prevent direct optical interference between densely packed light sources while maintaining their spatial proximity for high resolution, effectively mediating between the need for density and the need to eliminate crosstalk.
3Area of stationary object
If multiple light source units are connected to form large displays, then large-sized displays are achieved, but connection complexity and system integration difficulty increase
Solution Approach 1:
The patent designs universal connection interfaces and standardized mounting structures that can be applied across all light source units regardless of position or size. This universality simplifies the connection process for forming large displays, as the same connection mechanisms work throughout the system, reducing integration complexity despite the increased number of connections required.
Solution Approach 2:
The patent employs a modular nested structure where smaller light source units can be combined to form larger display configurations. The connection system is designed to accommodate nested arrangements of units at different scales, allowing complex large displays to be built from simpler modular components with standardized connection protocols at each level of nesting.
