Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If passive power control (switching off power, tripping upon overcurrent and overload) is used, then device complexity is reduced, but grid stability and reliability deteriorate due to fluctuations and shocks
Solution Approach 1:
The patent implements active feedback control by establishing bidirectional communication between the energy control apparatus and power consumption devices. The system continuously monitors power consumption data and provides real-time feedback to adjust power allocation, replacing passive switching with dynamic responsive control that maintains grid stability while managing complexity through intelligent coordination.
Solution Approach 2:
The energy control apparatus serves as an intermediary between the power supply system and power consumption devices. It actively manages power allocation by receiving power consumption data from devices, determining available power capacity, and coordinating startup sequences, thereby mediating between supply and demand to prevent grid shocks while maintaining system reliability.
2Reliability
If active control over the grid is implemented, then grid stability and reliability are improved, but device complexity increases due to communication and coordination requirements
Solution Approach 1:
The energy control apparatus performs multiple functions within a single centralized system: it communicates with power consumption devices, collects power consumption data, determines available power capacity, and coordinates startup sequences. By consolidating these diverse functions into one multi-functional apparatus, the patent manages complexity through functional integration rather than proliferation of separate control systems.
3Ease of operation
If power is allocated without considering startup power requirements, then ease of operation is improved, but power supply reliability deteriorates when startup power exceeds available capacity
Solution Approach 1:
The system performs preliminary assessment of power availability before allowing device startups. The energy control apparatus determines the available power capacity in advance and uses this information to coordinate startup sequences, ensuring that cumulative startup power requirements do not exceed available capacity. This preliminary planning maintains ease of operation while preventing power supply failures.
Solution Approach 2:
The patent implements continuous monitoring of power consumption data and dynamic adjustment of power allocation to maintain uninterrupted power supply. By continuously tracking the cumulative startup power of devices and comparing it against available capacity, the system ensures continuous reliable operation, preventing power outages while allowing devices to operate with ease.
