Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-quality rendering techniques are used, then rendering quality is improved, but rendering speed deteriorates due to significant processing resources and time required
Solution Approach 1:
The patent pre-processes and stores multiple perspective views of objects in a database before runtime. During real-time application, the system retrieves and merges these pre-computed views rather than performing complex real-time rendering calculations, thus achieving high quality with minimal processing time.
Solution Approach 2:
The system creates and stores multiple copied perspectives of each object from different angles and positions. These pre-generated image copies are then retrieved and merged to construct arbitrary views, avoiding the need for computationally intensive real-time rendering while maintaining high visual quality.
2Productivity
If lower quality but faster rendering techniques are used, then rendering speed is improved, but rendering quality deteriorates
Solution Approach 1:
The patent merges multiple pre-rendered images from different perspectives to construct a complete arbitrary view. This merging process combines the strengths of multiple lower-resolution or differently-angled images to produce a high-quality final image, achieving both speed and quality simultaneously.
Solution Approach 2:
Instead of improving quality within a single rendering dimension (time or resolution), the patent adds a new dimension by combining multiple pre-computed perspectives. This multi-dimensional approach allows the system to achieve high quality through image merging rather than through computationally expensive single-view rendering.
3Productivity
If rasterization is used for fast rendering, then rendering speed is improved, but rendering quality deteriorates
Solution Approach 1:
The system performs the computationally intensive rendering work in advance by pre-processing objects into multiple perspective views. During real-time operation, only lightweight image retrieval and merging operations are needed, eliminating the quality-speed trade-off by shifting the computational burden to offline preprocessing.
