Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex measuring devices are used to determine electrical power consumption, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex electrical measuring devices with a calculation-based approach using existing control data. Instead of using physical measurement instruments to determine power consumption, the system calculates energy consumption from stored characteristic parameters and control variables, substituting mechanical/electrical measurement systems with computational methods.
Solution Approach 2:
The patent creates a virtual model of power consumption by calculating it from characteristic parameters and control variables rather than physically measuring it. This computational copy of the measurement data achieves the same purpose as physical measuring devices without their complexity and cost.
2Adaptability or versatility
If multiple heating control devices are powered from a common power supply, then system integration is improved, but network load increases
Solution Approach 1:
The patent implements feedback by continuously monitoring control variables and characteristic parameters to calculate real-time energy consumption data. This feedback mechanism enables the system to track and report power consumption, allowing for network load optimization while maintaining common power supply integration.
Solution Approach 2:
The patent introduces energy consumption calculation as an intermediary function between the heating control devices and the power supply network. By calculating and reporting energy consumption data, the system provides information that mediates the relationship between integrated devices and network load, enabling better power management.

AI summary
When operating a system (1) with at least one heating control and/or regulation device (2, 3, 4) for heating elements (12), according to the invention, values for energy consumption and/or current power input of the heating elements (12) are determined without using measured values for electrical currents, based on characteristic parameters of the heating elements (12) and on values of control and/or regulation variables for controlling and/or regulating the heating power of the heating elements (12). This allows the network load caused by the heating control and/or regulation devices (2, 3, 4) to be determined, reported, and optimized even without complex and therefore expensive measuring devices in the heating control and/or regulation device (2, 3, 4).
