Engineering Contradiction Analysis
1Productivity
If manual data acquisition and structure analysis method are used for durability analysis, then analysis can be performed with existing tools, but the design time becomes very long and requires extensive investigation of boundary conditions
Solution Approach 1:
The system automatically generates 3D models for each constituent element and prepares durability analysis model definitions without requiring manual data acquisition. The automated process includes generating models from design data, preparing analysis model definitions, and executing dynamics and fatigue analyses, thereby eliminating manual intervention and significantly reducing design time.
Solution Approach 2:
The patent replaces manual mechanical processes of data acquisition and model preparation with an automated computational system. The system uses computer-based generation of 3D models, automatic preparation of analysis model definitions, and automated execution of analyses, substituting manual operations with digital automation to improve productivity.
2Reliability
If structure analysis method is applied to each constituent element, then durability can be analyzed, but large deviation in analysis results occurs depending on boundary condition settings
Solution Approach 1:
The system uses a universal automated process that applies the same standardized procedure to all constituent elements. The automated generation of 3D models and preparation of durability analysis model definitions ensures consistent boundary condition application across all elements, eliminating the variability that occurs when manually adjusting boundary conditions for each element type.
Solution Approach 2:
The patent automatically adjusts and standardizes boundary condition parameters through the automated preparation of durability analysis model definitions. By using computer-generated models and standardized analysis protocols, the system maintains consistent parameter settings across all constituent elements, preventing large deviations in analysis results that occur with manual parameter adjustment.
3Loss of time
If automated 3D model generation and durability analysis model preparation are implemented, then time required for durability analysis is significantly decreased, but system complexity increases
Solution Approach 1:
The automated system is divided into distinct functional modules: 3D model generation unit, durability analysis model preparation unit, dynamics analysis unit, and fatigue analysis unit. Each module handles a specific task independently, making the complex automated system manageable and easier to implement while achieving significant time reduction through automation.
