Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If decentralized energy sources are integrated into the distribution network, then local energy generation increases, but grid stability deteriorates due to supply fluctuations
Solution Approach 1:
The control device continuously monitors the electrical power output from decentralized generation devices and the power consumption of consumers, using this feedback information to dynamically calculate energy allocation coefficients and adjust distribution in real-time, thereby maintaining grid stability despite supply fluctuations
Solution Approach 2:
The system transitions from static energy allocation to dynamic allocation by continuously adjusting energy allocation coefficients based on real-time measurements of power output and consumption, allowing the distribution network to adapt to fluctuating decentralized energy supply
2Quantity of substance
If decentralized energy sources are integrated into the distribution network, then local energy generation increases, but measurement and control complexity increases
Solution Approach 1:
The control system is segmented into distributed measurement devices at consumer locations and a central control device that processes measurements and calculates allocation coefficients, distributing the control functionality rather than concentrating all complexity in one location
Solution Approach 2:
The control device acts as an intermediary between decentralized generation devices and multiple consumers, receiving power output measurements and consumption measurements, then mediating the energy allocation by calculating and applying energy allocation coefficients to balance supply and demand
3Productivity
If energy allocation coefficients are determined dynamically, then energy distribution efficiency improves, but control and regulation complexity increases
Solution Approach 1:
The control device automatically determines energy allocation coefficients based on measured power output and consumption data without requiring manual intervention, and automatically controls controllable consumers to align their power consumption with available supply, enabling the system to self-regulate
Solution Approach 2:
The patent replaces manual or mechanical energy allocation methods with an automated electronic control system that uses electrical measurements and computational algorithms to dynamically determine allocation coefficients and control energy distribution
