Power Strip Socket Sensing to Prevent False Energization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power strips either energize all sockets upon connection, risking electric shock from false contacts, or require manual operation, which can lead to forgotten settings causing further false energizations.
Innovation Solution
The implementation of independently powered sensors to detect plug insertions in each socket, ensuring power is only supplied when a plug is detected, eliminating the need for manual operation and reducing false energizations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If all sockets are energized upon connection, then power availability is improved, but safety risk increases due to electric shock from false contacts
Solution Approach 1:
The sensor performs preliminary detection of plug presence before the socket is energized. The control unit checks the sensor signal indicating plug insertion, and only then activates power supply to that socket, preventing electric shock from false contacts while ensuring power is available when needed
2Object-affected harmful factors
If manual operation is required to energize sockets, then safety is improved by preventing false energization, but ease of operation deteriorates due to user intervention requirements
Solution Approach 1:
The power strip performs self-service by automatically detecting plug insertion through sensors and autonomously controlling power supply to each socket. The control unit receives sensor signals and automatically activates or deactivates power without requiring any user operation, eliminating manual intervention while maintaining safety
3Measurement precision
If sensors are independently powered to detect plug insertion, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary detection using independently powered sensors before energizing sockets. The control unit receives detection signals from these sensors and only activates power supply when plug presence is confirmed, ensuring accurate measurement while managing system complexity through controlled sensor deployment

AI summary
The present invention relates to an energization method and apparatus for a power strip, a computer program and a recording medium. The method comprises: de-energizing respective sockets of the power strip; detecting use states of the respective sockets of the power strip using independently powered sensors; and when the use state of a first socket of the power strip is having a plug inserted therein, controlling the first socket to be energized. The present technical solution can reduce the risk of occurrence of electric shock due to false contact, and does not require a user's manual operation to energize the sockets, thereby reducing the user's operations.
