Home Appliance Power Control for Space Load Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple home appliances are used simultaneously in one space, the maximum allowable power of the space is often exceeded, leading to power shutdown issues. There is a need for a technology that controls the operation of home appliances in consideration of power consumption.
Innovation Solution
A system and method for controlling home appliances that includes a user terminal, a server, and home appliances equipped with communication modules. The system allows users to register and manage home appliances, and the server determines whether to operate additional appliances based on the total expected power consumption in the space, ensuring it does not exceed the maximum allowable power.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple home appliances are used simultaneously in one space, then the utility and functionality of the space is improved, but the power consumption exceeds the maximum allowable power
Solution Approach 1:
The system performs preliminary calculation of total power consumption before allowing appliances to operate. The server receives operation requests, calculates the sum of power consumption for all currently operating appliances plus the requested appliance, and determines in advance whether this exceeds the maximum allowable power, thereby preventing power overload before it occurs.
Solution Approach 2:
The system implements feedback by continuously monitoring the operation status of appliances and dynamically adjusting whether new operation requests are permitted. The server provides feedback to users about whether additional appliances can be operated based on current power consumption levels, enabling adaptive control of appliance operations to maintain power within safe limits.
2Reliability
If the operation of home appliances is controlled to prevent power shutdown, then the reliability of appliance operation is improved, but the complexity of the control system increases
Solution Approach 1:
The server acts as an intermediary between users and home appliances for operation control. Instead of implementing complex control logic within each appliance or requiring direct user management of power consumption, the server centralizes the calculation and decision-making process, simplifying the overall system architecture while ensuring reliable operation through centralized power consumption management.

AI summary
The present disclosure relates to a system and method for controlling home appliances that operates home appliances using a user terminal and controls 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, when a first home appliance is 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.
