Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed depth data is captured to maintain high measurement precision, then scanning accuracy is improved, but file size and processing time increase significantly
Solution Approach 1:
The patent segments the 3D mesh generation process into progressive stages, building the mesh incrementally from depth data. This allows the system to process and display intermediate results at different levels of detail, reducing the time required to handle complete detailed scans while maintaining the option to access full precision data when needed.
Solution Approach 2:
The patent implements dynamic mesh simplification where the level of detail can be adjusted during processing. The system can adaptively simplify or enhance mesh complexity based on processing requirements, allowing real-time preview at lower detail levels while preserving the ability to access high-precision detailed data structures.
2Manufacturing precision
If complex mesh models are generated to maintain manufacturing precision, then 3D modeling accuracy is improved, but memory usage and processing speed deteriorate
Solution Approach 1:
The patent creates simplified representative copies of complex 3D models at different levels of detail. These simplified meshes capture the essential geometric information needed for manufacturing while using significantly less memory and processing resources compared to the original detailed depth data and complex mesh structures.
Solution Approach 2:
The patent changes geometric parameters of the mesh models dynamically, adjusting resolution, polygon count, and detail levels based on processing requirements. This allows the system to maintain manufacturing precision when needed while optimizing processing speed by using coarser approximations during preliminary stages.
3Ease of operation
If real-time preview is implemented to improve ease of operation, then user feedback capability is improved, but processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary mesh generation and simplification actions before user interaction. By pre-processing the depth data into simplified mesh representations, the system enables real-time preview and user feedback without requiring complex computations during the actual user interaction, thus reducing processing time while maintaining ease of operation.
