Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single three-dimensional image displaying apparatus is used, then the field of view can be maintained, but the resolution and depth reproducibility are insufficient
Solution Approach 1:
The patent divides the three-dimensional image display system into multiple independent displaying apparatuses, each responsible for generating a specific group of viewpoints. This segmentation allows each apparatus to operate at high resolution while collectively providing comprehensive coverage, resolving the contradiction between high resolution and system complexity by distributing the computational and display burden across multiple specialized units.
Solution Approach 2:
The patent transitions from a single apparatus handling all viewpoints to multiple apparatuses organized in a spatial array, adding a dimensional aspect to the system architecture. Each apparatus is positioned to emit light rays toward specific regions, creating a multi-dimensional viewpoint generation system that achieves high resolution without excessive complexity through spatial distribution.
2Manufacturing precision
If multiple groups of viewpoints are generated to improve depth reproducibility, then the depth perception improves, but the field of view may be restricted
Solution Approach 1:
The patent merges the output of multiple three-dimensional image displaying apparatuses through an optical system that combines light rays from different apparatuses. Each apparatus generates a specific group of viewpoints, and the optical system integrates these groups to form a comprehensive view that maintains both high depth reproducibility and wide field of view, effectively combining the strengths of multiple separate systems.
Solution Approach 2:
The patent introduces an optical system as an intermediary between the multiple three-dimensional image displaying apparatuses and the user's eyes. This intermediary optical system receives light rays from multiple apparatuses, performs necessary optical processing, and delivers the combined imagery, enabling the system to achieve high depth reproducibility without compromising the field of view.
3Measurement precision
If light rays from multiple three-dimensional image displaying apparatuses are combined, then high resolution is achieved, but optical alignment becomes complex
Solution Approach 1:
The patent applies local quality by assigning each three-dimensional image displaying apparatus a specific functional role and spatial position optimized for its purpose. Each apparatus is configured to emit light rays toward particular regions, and the optical system is designed with corresponding local optimization for receiving and processing light from each specific apparatus, simplifying the overall alignment complexity through localized specialization.
