Engineering Contradiction Analysis
1Ease of operation
If manual layout method is used, then ease of operation is improved, but productivity and analysis capability deteriorate
Solution Approach 1:
The patent replaces manual mechanical layout methods with an automated computer-based simulation system. The system uses software to automatically generate facility layouts, calculate production metrics, and simulate different scenarios, eliminating the need for manual calculations and derivations while significantly improving productivity and analysis capability.
Solution Approach 2:
The simulation system performs self-service by automatically conducting production calculations, generating layout configurations, and providing analysis results without requiring manual intervention. The system independently executes simulations, compares different layout methods, and presents optimized solutions, enabling the facility planning process to serve itself.
2Adaptability or versatility
If new facility type is added, then adaptability is improved, but calculation capability without simulation tool deteriorates
Solution Approach 1:
The simulation system is designed with universal functionality to handle various facility types and layout configurations. It can accommodate new facility types by integrating their parameters and characteristics into the existing simulation framework, allowing the system to perform multiple functions including layout generation, production calculation, and scenario comparison across different facility types without requiring separate tools.
Solution Approach 2:
The system manages adaptability through parameter changes by allowing users to input and modify facility-specific parameters such as processing times, transmission times, and facility dimensions. When new facility types are introduced, their unique parameters are incorporated into the simulation model, enabling the system to automatically adjust calculations and provide accurate production projections for diverse facility configurations.
3Productivity
If automated simulation is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent employs an intermediary approach by using a computer-based simulation system as a mediator between the facility layout design and production analysis. This intermediary system automates complex calculations and simulations while presenting results in an accessible format, bridging the gap between detailed technical parameters and decision-making requirements without requiring direct complex device operations.
