Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual post-processing operations are performed by operators, then flexibility in adjusting settings based on product characteristics is improved, but labor intensity and exposure to hazardous chemicals increase
Solution Approach 1:
The control apparatus automatically analyzes CAD and slicing files to extract product information and determines optimal post-processing parameters without human intervention. The system serves itself by making intelligent decisions about washing, curing, and drying parameters based on product characteristics, eliminating the need for operators to manually handle hazardous chemicals while maintaining adaptive parameter adjustment.
Solution Approach 2:
The patent replaces the manual mechanical operation system with an automated control system that uses computer-aided design analysis and algorithm-based parameter determination. The control apparatus substitutes human operators with automated computational methods that analyze product geometry and material properties to determine optimal post-processing settings, thereby eliminating exposure to hazardous chemicals.
2Productivity
If automated control is implemented, then productivity and safety are improved, but device complexity increases
Solution Approach 1:
The control apparatus is designed as a universal system that handles multiple post-processing operations (washing, curing, drying) through a single integrated platform. It can process various product types by analyzing different CAD and slicing file formats, extracting relevant information, and automatically determining appropriate parameters for each operation type, thereby achieving high productivity without proportionally increasing complexity.
Solution Approach 2:
The system uses CAD files and slicing files as intermediaries to bridge the gap between product design and post-processing parameters. Rather than requiring complex sensors and real-time measurements, the control apparatus extracts necessary information from existing digital models, using these files as mediators to automatically determine washing, curing, and drying parameters, thus achieving automation with manageable complexity.
3Manufacturing precision
If detailed parameter analysis is performed on CAD and slicing files, then manufacturing precision is improved, but processing time increases
Solution Approach 1:
The control apparatus extracts only the essential information needed for post-processing from the comprehensive CAD and slicing files. It identifies and extracts key parameters such as product volume, surface area, complexity metrics, and material properties, rather than processing all available data. This selective extraction maintains high manufacturing precision by focusing on the most relevant parameters while significantly reducing processing time.
Solution Approach 2:
The system performs partial analysis by focusing on the most critical parameters that have the greatest impact on post-processing quality. Rather than exhaustively analyzing every aspect of the CAD and slicing files, it applies analysis to the essential geometric and material properties that directly influence washing, curing, and drying parameters, achieving sufficient precision with reduced computational effort and time.
