Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple non-standardized renewable power generation technologies and power storage technologies are integrated, then energy production and storage capability is improved, but system complexity and integration difficulty increase
Solution Approach 1:
The patent introduces a power control system as an intermediary device that standardizes the integration interface between multiple non-standardized renewable power generation technologies and power storage technologies. The system includes a controller that receives power from multiple sources through standardized conversion circuits, managing the complexity internally while presenting a unified interface to the grid and loads.
Solution Approach 2:
The power control system is designed with multi-functional capability to handle various power generation sources (solar, wind, etc.) and storage technologies simultaneously. The controller can manage power conversion, storage charging/discharging, grid interaction, and load distribution through a single integrated platform, reducing the need for separate systems for each function.
2Adaptability or versatility
If consumer operated power generation systems and energy storage systems are integrated with the utility power grid, then energy autonomy is improved, but control and balancing difficulty increases
Solution Approach 1:
The power control system incorporates feedback mechanisms where the controller continuously monitors power input from generation sources, storage state, grid conditions, and load requirements. Based on this feedback, the controller automatically adjusts power conversion ratios, charging/discharging rates, and grid exchange to maintain balance and autonomy without requiring complex manual control.
Solution Approach 2:
The system is designed to autonomously manage its own power balancing and control functions. The controller automatically determines optimal power distribution among generation sources, storage devices, grid connection, and loads based on real-time conditions, eliminating the need for external control intervention and simplifying operation for the consumer.
