Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a heating control system uses neural networks to optimize energy supply based on exterior temperature, then energy optimization is improved, but the system becomes inapplicable to installations with thermostatic valves and causes drift
Solution Approach 1:
The patent introduces a modified exterior temperature as an intermediary parameter that mediates between the neural network's energy optimization calculations and the actual heating system control. Instead of directly using raw exterior temperature values that cause drift in systems with thermostatic valves, the system processes this temperature through additional calculations involving interior temperature predictions and comfort parameters to generate a modified temperature value that is suitable for controlling the mixing valve while maintaining compatibility with thermostatic valves.
Solution Approach 2:
The patent transforms the exterior temperature parameter into a modified exterior temperature parameter through mathematical processing. This parameter transformation allows the system to maintain energy optimization benefits while adapting to different system configurations, particularly making the system compatible with installations using thermostatic valves by changing how temperature data is utilized in the control algorithm.
2Use of energy by moving object
If the heating control system is installed to optimize energy supply, then energy efficiency is improved, but installation cost and complexity increase due to specialist intervention
Solution Approach 1:
The patent designs the heating control system to be universally applicable to multiple types of heating installations, including both systems with and without thermostatic valves. By making the system multi-functional and adaptable to different configurations through the modified temperature parameter approach, it eliminates the need for specialist intervention and complex customization during installation, thereby reducing installation costs and complexity while maintaining energy efficiency benefits.
3Use of energy by moving object
If the system uses exterior temperature for control, then energy optimization is achieved, but the system drifts when thermostatic valves are closed
Solution Approach 1:
The patent implements a feedback mechanism by incorporating interior temperature predictions and actual comfort parameters into the calculation of modified exterior temperature. This feedback loop allows the system to continuously adjust the temperature parameter based on actual system state and performance, preventing drift when thermostatic valves are closed while maintaining energy optimization. The system uses this feedback to ensure stability and reliability across different operating conditions.
