Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the radiation panel temperature is adjusted without considering equipment characteristics, then the control system is simple, but the operation efficiency deteriorates
Solution Approach 1:
The controller stores panel characteristics data and device characteristics data in advance before operation. This preliminary storage of equipment-specific parameters enables the system to perform efficient temperature control without complex real-time calculations, resolving the contradiction between simple control and high efficiency
Solution Approach 2:
The system determines a time-series pattern of heat quantity by changing and adjusting multiple parameters including panel temperature, heat quantity, and time sequences based on stored characteristics data. This parameter optimization enables efficient operation while maintaining manageable control complexity
2Ease of operation
If the radiation panel temperature is adjusted without considering characteristics data, then the system is easy to operate, but the temperature adjustment accuracy deteriorates
Solution Approach 1:
The system collects indoor environment data and panel temperature data from sensors, compares this feedback with target values, and adjusts the heat quantity time-series pattern accordingly. This feedback mechanism ensures accurate temperature adjustment while maintaining ease of operation through automated control
Solution Approach 2:
Characteristics data for both the radiation panel and air conditioner are stored in advance, enabling the system to perform accurate temperature adjustments without requiring complex real-time decision-making by the operator, thus maintaining ease of operation while achieving precision
3Device complexity
If generic control is used without equipment characteristics, then the control method is simple, but the energy efficiency deteriorates
Solution Approach 1:
The system optimizes energy efficiency by determining a time-series pattern of heat quantity that changes multiple parameters including panel temperature, heat quantity magnitude, and temporal distribution. This parameter optimization achieves better energy efficiency while keeping the control methodology manageable
Solution Approach 2:
Instead of static generic control, the system implements dynamic control where the heat quantity pattern adapts to specific equipment characteristics and environmental conditions. This dynamic approach improves energy efficiency without requiring overly complex control infrastructure
