Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only airflow side simulation is used for control optimization, then temperature control accuracy is improved, but equipment operational constraints are violated
Solution Approach 1:
The patent combines the airflow side model (simulating temperature distribution) and equipment side model (simulating device behavior constraints) into a unified coupled optimization system. This integration allows simultaneous consideration of both temperature control accuracy and equipment operational constraints, resolving the contradiction by making the system consider both aspects together rather than separately
2Reliability
If equipment side constraints are added to the optimization model, then operational reliability is improved, but computational complexity increases
Solution Approach 1:
The patent segments the complex optimization problem into two distinct but coupled models: the airflow side model handling temperature field simulation and the equipment side model handling device behavior simulation. This segmentation allows each model to focus on specific aspects, making the overall complex problem more manageable while maintaining comprehensive optimization
3Measurement precision
If inverse analysis method is used for coupled optimization, then control precision is improved, but computational time increases
Solution Approach 1:
The patent performs preliminary simulation to obtain boundary condition temperatures and heating energy environment data before executing the inverse analysis. This preliminary action prepares the necessary input data in advance, allowing the subsequent inverse analysis to focus specifically on optimizing control parameters, thereby improving control precision while reducing the overall computational time required
