Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional physical equipment-based simulation platforms are used, then intuitive equipment understanding is improved, but site size requirements and safety issues increase
Solution Approach 1:
The patent creates virtual copies of physical equipment through detailed 3D modeling and simulation. The virtual platform replicates the functionality and behavior of actual MSWI equipment, allowing users to interact with and understand equipment operations without requiring physical presence at a large facility. This virtual copying approach maintains intuitive understanding while eliminating space constraints.
Solution Approach 2:
The patent replaces physical mechanical equipment with a virtual simulation system. Instead of requiring actual incineration equipment, conveyors, and processing machinery occupying significant space, the invention uses computer-based virtual models that replicate equipment behavior. This substitution eliminates the need for large physical sites while preserving equipment understanding through interactive simulation.
2Device complexity
If single-loop control simulation platforms are used, then platform simplicity is improved, but multiple-input and multiple-output characteristics are not considered
Solution Approach 1:
The patent implements a multi-functional simulation platform that handles multiple-input and multiple-output control characteristics. The system integrates various process variables, control loops, and equipment interactions within a unified virtual environment. This allows the platform to simulate complex MSWI process dynamics including material flow, energy balance, and environmental controls simultaneously, providing comprehensive adaptability while maintaining platform coherence.
3Device complexity
If actuator model, process object model and instrument model are not separated, then model integration is improved, but signal transmission authenticity and interference simulation are reduced
Solution Approach 1:
The patent segments the simulation model into distinct functional components: actuator models, process object models, and instrument models. Each component is independently developed and validated, then integrated through defined interfaces that replicate actual signal transmission pathways. This segmentation allows for authentic simulation of signal transmission characteristics, including noise, delays, and interference, while maintaining overall system integration through coordinated model interactions.
