Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual management mode is used for truck dispatching, then operational simplicity is maintained, but automation level and response efficiency deteriorate
Solution Approach 1:
The patent creates digital twin copies of physical trucks, loaders, and dispatchers. These digital twins virtualize the dispatching system, enabling automated decision-making while maintaining a simplified interface. The digital twin technology allows the system to process complex dispatching logic virtually without requiring complex physical infrastructure.
Solution Approach 2:
The patent replaces manual mechanical dispatching operations with an automated computer-based system. The automated dispatching system uses algorithms to optimize truck routing, loading, and unloading decisions, substituting human manual control with intelligent automated control while reducing overall system complexity through software-based management.
2Speed
If manual dispatching operations are performed, then system simplicity is maintained, but response time to abnormal situations deteriorates
Solution Approach 1:
The patent implements real-time feedback mechanisms where digital twins continuously monitor the status of trucks, loaders, and transportation paths. When abnormal situations are detected (such as equipment failure or traffic congestion), the system immediately receives feedback and automatically adjusts dispatching decisions, enabling rapid response without manual intervention.
Solution Approach 2:
The system performs preliminary actions by pre-planning multiple dispatching scenarios and preparing alternative routes before abnormal situations occur. When issues arise, the system can quickly switch to pre-prepared solutions, significantly reducing response time compared to reactive manual decision-making.
3Extent of automation
If computer intervention is added to monitor and process dispatching information, then automation is improved, but manual operation requirements and abnormal case handling complexity increase
Solution Approach 1:
The patent enables the dispatching system to serve itself through automated decision-making algorithms. The digital twin dispatcher automatically generates optimal dispatching plans based on real-time data, eliminating the need for manual operations. The system handles abnormal cases autonomously by re-optimizing routes and resource allocation without requiring human intervention.
