Power Strip Socket Control via Device State Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often get overcharged when left plugged into a power strip after they have completed their tasks, leading to power waste and potential device damage, as existing solutions do not effectively monitor and control the charging state of devices.
Innovation Solution
A power supply control method and apparatus for a power strip that acquires the working state of connected electronic devices, either via wired or wireless communication, to determine the appropriate power supply state, including disabling power when a preset task is completed, thereby preventing overcharging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power strip continuously supplies power to electronic devices after task completion, then the devices remain ready for immediate use, but power waste occurs and device damage may result from overcharging
Solution Approach 1:
The power strip incorporates a control module that receives state information from electronic devices and provides feedback to adjust power supply. The control module monitors device status (charged state, working state) and automatically adjusts power supply accordingly, enabling the power strip to respond to device needs rather than continuously supplying power
Solution Approach 2:
The electronic device itself reports its state to the power strip through state information transmission, allowing the device to serve its own monitoring function. The power strip then uses this self-reported information to automatically control power supply, eliminating the need for manual user intervention
2Loss of energy
If the power strip monitors and controls power supply based on device working state, then power waste and device damage are prevented, but system complexity increases due to communication and control mechanisms
Solution Approach 1:
The control module serves multiple functions: receiving state information from devices, determining device working states, controlling power supply to individual sockets, and preventing both power waste and overcharging. This multi-functionality reduces the need for separate dedicated components for each function
Solution Approach 2:
The control module acts as an intermediary between the power supply source and the electronic devices. It receives simple state information from devices and translates it into appropriate power supply control actions, mediating the interaction between power source and load
3Reliability
If the power strip uses wired communication to acquire device state information, then communication reliability is improved, but ease of operation decreases due to connection requirements
Solution Approach 1:
The control module serves as an intermediary that accepts multiple communication modes. It can receive state information through wired connections (providing reliable communication) or wireless connections (providing convenience), mediating between different communication requirements
4Loss of energy
If the power strip disables power supply when devices complete tasks, then energy saving is achieved, but device availability may be reduced if devices need immediate re-use
Solution Approach 1:
The control module continuously monitors device state information and provides feedback-based power supply control. When devices report completed tasks or charging completion, the control module receives this feedback and adjusts power supply accordingly, enabling dynamic response to device needs

AI summary
The present invention relates to a power supply control method and apparatus of a power strip and the power strip, a computer program and a recording medium. The method comprises: acquiring a charge state or working state of an electronic device; and controlling a power supply state of a socket of the power strip which is connected with the electronic device, according to the charge state or working state of the electronic device. The present invention enables flexibly controlling a power supply state of a socket of a power strip, so that an electronic device can be prevented from being overcharged and power can be prevented from being supplied to an electronic device that does not need to be power-supplied, thereby not only saving power and but also protecting the electronic device.
