Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If staged or regional power outages are adopted to avoid safety accidents caused by excessive power load, then the electricity load is reduced, but user convenience deteriorates due to great inconvenience
Solution Approach 1:
The system performs preliminary actions by proactively controlling authorized devices to execute energy-saving operations before the power grid becomes overloaded. The server device receives demand instructions and preemptively adjusts device operations during peak demand periods, preventing the need for staged power outages while maintaining user convenience through automated, transparent load management.
2Ease of operation
If remote control of authorized devices is implemented to perform energy-saving operations, then user selectivity is improved and convenience is enhanced, but system complexity increases
Solution Approach 1:
The server device acts as an intermediary between the power grid operator and user devices. It receives demand instructions from the power grid, processes them according to user-authorizations, and translates them into appropriate control commands for authorized devices. This intermediary layer simplifies the overall system architecture by centralizing the complexity of load management logic while maintaining simple, standardized interfaces for both users and devices.
3Loss of energy
If energy-saving operations are performed during performing time slot to reduce power grid load, then electricity load is alleviated, but energy consumption increases for the authorized device
Solution Approach 1:
The system changes operational parameters of authorized devices during performing time slots to achieve energy-saving operations. Instead of simply turning devices off, the server device adjusts parameters such as operating power levels, operational intensity, or task scheduling to reduce overall power consumption while maintaining essential functions. This allows the device to consume less energy during peak grid demand periods while still providing useful service.

AI summary
An energy-saving control method includes obtaining a demand instruction configured to indicate an energy-saving operation and a performing time slot of the energy-saving operation. The energy-saving operation is determined based on load data of a power grid and is configured to reduce a load of the power grid. The method further includes transmitting a first control message configured to control an authorized device to perform the energy-saving operation in response to detecting that time reaches the performing time slot, and transmitting a second control message configured to control the authorized device to stop performing the energy-saving operation in response to detecting that time is outside the performing time slot.
