Motor-Driven Appliance Sleep Mode Control via External Wakeup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor-driven appliance systems require user intervention to switch from sleep mode to active mode, reducing usability and increasing power consumption.
Innovation Solution
Incorporating a communication device that allows external wakeup signals to switch control circuits from sleep mode to active mode without user operation, and optionally using a switch for user-driven activation, thereby reducing power consumption and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the control circuit switches to sleep mode to reduce power consumption, then power consumption is reduced, but user operation becomes more complex requiring main switch activation
Solution Approach 1:
The communication device serves as an intermediary that receives external wakeup signals and transmits them to the control circuit. This mediator enables the control circuit to wake up automatically without requiring direct user interaction with the main switch, thus maintaining ease of operation while achieving power savings through sleep mode
Solution Approach 2:
The control circuit is designed to automatically wake up upon receiving a wakeup signal through the communication device, eliminating the need for manual main switch operation. The system serves itself by autonomously transitioning from sleep mode to active mode based on external signals, improving both power efficiency and usability
2Speed
If the control circuit remains in active mode to maintain responsiveness, then system responsiveness is improved, but power consumption increases
Solution Approach 1:
The control circuit dynamically switches between active mode and sleep mode based on operational needs. During normal operation, it remains in active mode for immediate responsiveness. When idle, it transitions to sleep mode to conserve power, yet can quickly wake up upon receiving external signals through the communication device, thus maintaining responsiveness when needed while reducing overall power consumption

AI summary
A motor-driven appliance system in one aspect of an embodiment of the present disclosure includes a motor-driven appliance having a motor, at least one control circuit, and a communication device. The control circuit is configured to execute a process related to control of the motor-driven appliance. The communication device is configured to communicate with an external device. The control circuit is further configured to switch, when at least one predetermined sleep condition is satisfied, from an active mode in which the control circuit performs a normal operation to a sleep mode in which the control circuit stops part of the normal operation to thereby suppress power consumption; and to switch to the active mode when the communication device receives an external wakeup signal transmitted from the external device while the control circuit is in the sleep mode.
