Home Appliance Power Curve Scheduling for Circuit Load Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home systems struggle to meet the demand of running multiple household appliances simultaneously without exceeding the circuit's load capacity, often requiring the disconnection of already running appliances, which affects user experience and efficiency.
Innovation Solution
A control method that determines if the power curves of appliances meet off-peak running conditions, adjusts the running states of currently running appliances based on priority sequences, and allows new appliances to run within these conditions to avoid overloading, ensuring safe and efficient operation.

Engineering Contradiction Analysis
1Reliability
If the existing home system connects a newly started household appliance by automatically disconnecting power to at least one currently running household appliance, then the circuit load capacity is not exceeded, but the number of simultaneously running appliances is reduced
Solution Approach 1:
The system performs preliminary analysis of power curves before connecting a new appliance. By predicting future power consumption patterns and identifying off-peak periods in advance, the system can schedule appliance operation to avoid overload without disconnecting currently running appliances, thus maintaining both circuit safety and appliance availability
Solution Approach 2:
The system dynamically adjusts the operation schedule of appliances based on real-time power consumption patterns and predicted future demands. By flexibly shifting appliance operation to off-peak periods while maintaining their functional requirements, the system allows more appliances to run simultaneously without exceeding circuit capacity
2Ease of operation
If multiple household appliances run at the same time, then user convenience is improved, but the circuit load may be exceeded
Solution Approach 1:
The system continuously monitors actual power consumption of running appliances and compares it with predicted power curves. This feedback mechanism allows the system to adjust operation schedules in real-time, ensuring that user convenience is maintained while preventing circuit overload by dynamically responding to actual usage patterns
Solution Approach 2:
The system performs preliminary power curve analysis and predicts future power consumption patterns before appliances actually run. This allows the system to pre-plan operation schedules that maximize simultaneous appliance operation while staying within circuit safety limits, improving user convenience without compromising safety

AI summary
A control method for a home system includes obtaining the power curve of a household appliance to be run; obtaining power curves of all the currently running household appliances; and, if the power curve of the household appliance to be run and that of at least one currently running household appliance meet an off-peak running condition, making the household appliance to be run and the currently running household appliance run within an off-peak period of time. Without affecting the running states of all the currently running household appliances, the method can connect the household appliance to be run to a circuit, meets the demand of a user for making the household appliance to be run and the currently running household appliances simultaneously work, and does not exceed the load of the circuit, thereby improving the overall working efficiency of the home system.
