Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual procedures are used to correct mesh deformation, then mesh quality can be improved, but the operation becomes complicated and time-consuming
Solution Approach 1:
The mesh correction system performs self-service by automatically evaluating mesh quality and correcting deformations without requiring manual intervention. The quality evaluation unit assesses mesh elements and the correction unit automatically adjusts node positions based on evaluation results, enabling the system to serve itself rather than requiring external manual operations.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated computational system. Instead of analysts manually shifting node points using sequential procedures, the system uses a quality evaluation unit and correction unit that automatically calculate and apply corrections based on mesh quality metrics, substituting human mechanical operations with computational automation.
2Manufacturing precision
If manual correction procedures are used, then mesh quality can be improved, but the process requires significant time
Solution Approach 1:
The system performs preliminary quality evaluation before finalizing the mesh, identifying elements that require correction. The quality evaluation unit assesses mesh elements in advance and determines which ones need correction, allowing the correction unit to focus computational resources on problematic areas rather than manually inspecting and correcting the entire mesh sequentially.
Solution Approach 2:
The patent replaces time-consuming manual correction procedures with an automated computational system that rapidly evaluates mesh quality and applies corrections. The correction unit automatically calculates optimal node positions and updates the mesh structure without requiring analysts to perform sequential manual operations, dramatically reducing the time required for mesh correction while maintaining quality standards.
3Productivity
If automatic correction is implemented, then productivity is improved, but the device complexity increases
Solution Approach 1:
The mesh correction system is segmented into distinct functional units: a quality evaluation unit that assesses mesh elements and a correction unit that applies corrections. This segmentation allows each unit to perform its specific function independently, improving productivity through automated workflows while managing system complexity by organizing functionality into modular, manageable components with clear interfaces.
Solution Approach 2:
The correction unit serves multiple functions: it receives correction requests from the quality evaluation unit, calculates optimal node positions, updates mesh structures, and ensures quality standards are met. This multi-functionality improves productivity by consolidating correction operations into a single automated unit rather than requiring separate manual procedures for each correction task.
