Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If centralized cloud server computing is used for energy management, then data processing capability is improved, but computing burden and response time are worsened
Solution Approach 1:
The patent segments the centralized cloud server into multiple edge servers distributed at different locations. Each edge server processes data locally for its corresponding energy management system, reducing the need for data to travel to a centralized cloud server. This segmentation maintains data processing capability while significantly reducing response time by enabling local real-time processing.
2Productivity
If more computing resources are allocated to cloud server, then energy management capability is improved, but system complexity and cost are worsened
Solution Approach 1:
Instead of concentrating all computing resources in a single cloud server, the patent divides them into multiple edge servers distributed across different locations. Each edge server handles a portion of the computing workload locally, maintaining energy management capability while reducing system complexity through distributed architecture and avoiding the need for an overly complex centralized system.
3Quantity of substance
If renewable energy generation is increased, then green energy supply is improved, but intermittence and instability are worsened
Solution Approach 1:
The patent introduces energy storage devices as intermediaries between renewable energy generation and consumption. These storage devices buffer the intermittent and unstable renewable energy, storing excess energy when generation exceeds demand and releasing energy when demand exceeds generation, thereby maintaining energy stability while enabling increased renewable energy supply.
Solution Approach 2:
The system performs preliminary actions by storing renewable energy in advance when generation is high and conditions are favorable. The edge servers predict future energy needs and pre-store energy in storage devices, so that when renewable generation fluctuates or becomes insufficient, pre-stored energy is available to maintain stable supply without interruption.

AI summary
A household energy management and dispatching system includes: a power generation device, converters, an energy storage device, an energy management controller, local servers and a cloud server. Each of the converters is electrically connected to the power generation device, an electricity grid, the energy storage device and the energy management controller, configured to receive a power generation electrical energy or a utility power, and transmitted to the energy storage device and a load. Each of the local servers is electrically connected to each of the converters and configured to read an electrical energy information, a utility power information and an energy storage information. The cloud server is electrically connected to the local servers. The local servers perform an edge computing analysis to obtain an edge information according to the above information. The system is used to provide a buffer to stabilize the grid and power dispatching.
