Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution original 3D digital model is used for printing complex colored 3D objects, then printing quality and geometric fidelity are improved, but computation time and data handling requirements increase significantly
Solution Approach 1:
The patent applies preliminary action by performing model simplification and data reduction before the actual printing process. The system pre-processes the high-resolution 3D model to generate a simplified version that maintains essential geometric and color information while reducing data complexity, thereby preparing the data in advance to avoid lengthy computations during printing.
Solution Approach 2:
The patent creates a simplified copy of the original high-resolution 3D model. This approximated model serves as a representative copy that captures the essential features and visual appearance of the original object without containing all the detailed information, allowing the printing system to work with reduced data while maintaining acceptable fidelity.
2Manufacturing precision
If high-resolution original 3D digital model is used for printing complex colored 3D objects, then printing quality and geometric fidelity are improved, but data handling requirements increase significantly
Solution Approach 1:
The patent extracts only the essential geometric and color information from the high-resolution 3D model, removing redundant and excessive data. By selectively retaining critical features and discarding unnecessary details, the system reduces data handling requirements while preserving the key characteristics needed for quality printing.
Solution Approach 2:
The system performs preliminary data reduction and filtering to extract essential information before processing. This pre-extraction of critical data elements simplifies the data structure and reduces the burden on the printing system's data handling capabilities.
3Productivity
If model simplification is performed to reduce computation time, then productivity is improved, but geometric and color fidelity may deteriorate
Solution Approach 1:
The patent applies parameter changes by adjusting the simplification thresholds for geometric and color variations. The system modifies these parameters to control the degree of approximation, allowing optimization between processing speed and output quality. By carefully tuning these parameters, the system achieves acceptable fidelity while maintaining improved productivity.
Solution Approach 2:
The patent applies local quality by allowing different levels of approximation in different regions of the 3D model. Critical areas that require high fidelity are preserved with greater detail, while less critical areas undergo more aggressive simplification. This selective approach maintains color and geometric fidelity where needed while improving overall processing efficiency.
