Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing 3D rendering methods are used, then the rendering process is simple, but the visual quality is poor and scene changes are inconsistent
Solution Approach 1:
The patent segments the 3D scene into multiple 2D subgraphs that can be independently processed and adjusted. This allows for improved visual quality through selective manipulation of specific scene components without requiring complete scene re-rendering, thus balancing quality improvement with computational efficiency.
Solution Approach 2:
The patent transforms the traditional 3D rendering approach by decomposing the 3D scene into 2D subgraphs. This dimensionality change enables more flexible manipulation and adjustment of scene elements, improving visual quality while providing consistent scene changes across different views.
2Measurement precision
If camera pose is not considered in rendering, then the rendering process is faster, but the 3D geometry reconstruction is inaccurate
Solution Approach 1:
The patent performs preliminary extraction of camera pose information and 3D graph features before the actual rendering process. This pre-processing step enables accurate 3D geometry reconstruction by incorporating pose data upfront, while the subsequent rendering of 2D subgraphs maintains computational efficiency.
3Adaptability or versatility
If 3D graph features are not decomposed, then the rendering process is simpler, but scene synthesis and customization are difficult
Solution Approach 1:
The patent decomposes the 3D graph into multiple 2D subgraphs, each representing different aspects or components of the scene. This segmentation enables independent manipulation and customization of specific scene elements, greatly enhancing adaptability and versatility while maintaining manageable complexity through systematic organization.
Solution Approach 2:
The patent creates dynamically adjustable 2D subgraphs that can be selectively modified, adjusted, or synthesized based on specific requirements. This dynamic approach allows for flexible scene customization where individual subgraphs can be optimized independently, enhancing adaptability without requiring complete scene redesign.
