Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate software is used for low-dimensional and high-dimensional analyses, then each analysis can be performed with specialized tools, but manual parameter setting and separate data processing are required, increasing operation complexity and time consumption
Solution Approach 1:
The patent merges low-dimensional and high-dimensional analysis functions into a single integrated software system. The simulation apparatus includes both a low-dimensional analysis unit and a high-dimensional analysis unit within the same device, allowing users to perform both types of analyses without switching between separate software packages. This integration automatically handles parameter transfer and data processing, resolving the contradiction by maintaining specialized analysis capabilities while eliminating manual intervention requirements.
Solution Approach 2:
The simulation apparatus is designed with multi-functionality to perform both low-dimensional and high-dimensional fluid-flow analyses. The system includes a unified setting information management unit that handles parameters for both analysis types, and a result output unit that provides comprehensive analysis results. This universal design allows a single software system to fulfill multiple analysis needs that previously required separate specialized tools.
2Measurement precision
If manual parameter setting is performed for each analysis type, then analysis accuracy can be maintained, but time consumption and operation complexity increase significantly
Solution Approach 1:
The patent implements preliminary action by automatically transferring setting information and boundary conditions from the low-dimensional analysis to the high-dimensional analysis. The system pre-processes and prepares necessary parameters before the high-dimensional analysis begins, eliminating the need for manual parameter setting in the second analysis phase. This automated preliminary preparation maintains analysis accuracy while dramatically reducing the time and effort required.
Solution Approach 2:
The patent introduces an intermediary data transfer mechanism between the low-dimensional and high-dimensional analysis units. This intermediary system automatically extracts relevant physical quantities and boundary conditions from the first analysis and uses them as input for the second analysis, serving as a mediator that eliminates manual parameter setting while preserving data accuracy throughout the process.
3Adaptability or versatility
If separate data processing is performed for different analysis types, then specific analysis requirements can be met, but integrated evaluation of resin physical quantities and local kneading behavior becomes difficult
Solution Approach 1:
The patent merges the data processing systems for low-dimensional and high-dimensional analyses into a unified processing framework. The simulation apparatus includes a single result output unit that handles both types of analysis results, providing integrated evaluation capabilities for resin physical quantities and local kneading behavior. This consolidation maintains the adaptability to meet specific analysis requirements while simplifying the overall data processing system architecture.
