Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If inverse analysis is used to obtain control parameters for desired heating energy environment, then temperature control accuracy is improved, but equipment side constraints are not considered leading to insufficient control
Solution Approach 1:
The patent merges the airflow side model (thermal fluid analysis) with the equipment side model (device behavior simulation) into a coupled optimization system. This integration allows simultaneous consideration of both temperature distribution requirements and equipment operational constraints, resolving the contradiction between temperature control accuracy and control sufficiency by unified multi-objective optimization.
2Temperature
If only airflow side simulation is performed to control heating energy environment, then temperature distribution is optimized, but equipment capacity and behavior restrictions are not considered
Solution Approach 1:
The patent adds a new dimension to the simulation by introducing the equipment side model that operates in parallel with the airflow side model. This dimensional expansion incorporates equipment capacity, behavior restrictions, and operational constraints into the optimization process, enabling simultaneous optimization of temperature distribution and equipment adaptability.
3Measurement precision
If conventional temperature sensor control is used, then local temperature is controlled, but overall space heating energy environment is not accurately reflected
Solution Approach 1:
The patent introduces a thermal fluid analysis model as an intermediary between temperature sensors and control decisions. This intermediary processes local sensor data to simulate and predict overall space temperature distribution, compensating for the information loss from localized measurement and enabling accurate space-wide environmental control.
