Appliance Control Device for Sleep-Based Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling electrical appliances, such as remote control units and smart bands, are either cumbersome or require user interaction, failing to efficiently manage power supply based on user sleep states, leading to poor sleep quality and increased electricity consumption.
Innovation Solution
An electrical appliance control device that outputs events at predetermined intervals, determines user input, and adjusts power supply modes accordingly, allowing for automatic power management based on user state, including sound, vibration, or touch inputs, to maintain or switch operation modes and control power to electrical appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control unit is used to control electrical appliances, then user can turn off appliances manually, but user must operate buttons and cannot control appliances when sleeping
Solution Approach 1:
The system automatically detects user sleep state through motion sensors and autonomously controls appliance power without requiring user intervention. The control device itself performs the monitoring and decision-making functions that would otherwise require manual user action.
Solution Approach 2:
The patent replaces manual button operation with automated sensor-based detection and electronic control signals. Motion sensors detect user activity levels, and the system translates this into automatic power control decisions, eliminating the need for mechanical remote control operation.
2Extent of automation
If smart band is used to detect sleep state, then automatic power control can be achieved, but user must wear the smart band continuously
Solution Approach 1:
The patent extracts the sleep detection function from wearable devices and relocates it to the home environment's existing infrastructure (motion sensors in rooms). This eliminates the need for users to wear smart bands while maintaining automatic sleep state detection capability.
Solution Approach 2:
The system uses motion sensors as intermediaries between the user's physical state and the appliance control system. These sensors detect motion in the user's environment and translate it into sleep state information, serving as a bridge without requiring direct contact with the user's body.
3Ease of operation
If electrical appliances remain on during user sleep, then user can access them easily, but electricity consumption increases and sleep quality deteriorates
Solution Approach 1:
The system dynamically adjusts appliance power states based on real-time detection of user sleep status. When sleep is detected, the system automatically transitions appliances to standby or off states. When user activity is detected, appliances are automatically activated, creating a dynamic response to changing conditions.
Solution Approach 2:
The system implements closed-loop feedback by continuously monitoring motion sensors, detecting user sleep states, and adjusting appliance power accordingly. The control device receives feedback from sensors and modifies appliance operation in response, creating an adaptive system that responds to user needs.

AI summary
An electrical appliance control device for controlling power supplied to an electrical appliance, comprises: an output unit configured to output a predetermined event for each predetermined period during an operation mode; a determination unit configured to determine whether predetermined information is inputted by a user in response to the predetermined event; and a control unit configured to control power supplied to the electrical appliance corresponding to whether the predetermined information is inputted.
