Home Appliance Power Control to Prevent Overload Shutdowns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple home appliances are used in the same space, the total power consumption often exceeds the maximum allowable power, leading to power shutdown issues, necessitating a control system that manages power usage effectively.
Innovation Solution
A home appliance control system and method that uses a user terminal to communicate with a server, which registers and controls the operation of multiple appliances, ensuring that power consumption does not exceed a preset reference value by determining if additional appliance operation would exceed the maximum allowable power, and notifying users if operation is prevented to avoid shutdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple home appliances are used simultaneously in one space, then the functionality and convenience are improved, but the total power consumption exceeds the maximum allowable power, causing power shutdown
Solution Approach 1:
The server performs preliminary calculation of expected total power consumption before allowing an appliance to operate. When a user requests to operate an appliance, the server first determines whether adding this appliance's power consumption to the current total would exceed the maximum allowable power. If not, the appliance is allowed to operate; if yes, the operation is restricted. This preliminary check prevents power shutdown by anticipating the power load before it occurs.
2Reliability
If the operation of home appliances is restricted to prevent power shutdown, then power consumption is controlled within safe limits, but the ease of operation is reduced
Solution Approach 1:
The system provides real-time feedback to users about power consumption status. When an appliance operation would cause the total power to exceed the maximum allowable power, the server sends a notification message to the user terminal indicating that the operation is restricted due to power limits. This feedback mechanism maintains reliability by preventing power shutdown while informing users of the restriction, allowing them to make informed decisions about appliance operation.

AI summary
The present disclosure relates to a home appliance control system and method using a user terminal and controlling the operation of the home appliances arranged in a space in consideration of the amount of power consumed in the space. In the present disclosure, if a first home appliance is to be operated, the first home appliance is operated only when the total power consumption of the first home appliance and other home appliances that are already operating is less than or equal to a reference value.
