Electrical Equipment Remote Startup via Induction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical equipment in standby mode continues to consume power, which is inefficient and wasteful, as existing remote control systems do not effectively manage power supply to completely shut down the equipment.
Innovation Solution
A remote control system using electromagnetic induction to transmit and receive signals, allowing the electrical equipment to be turned on and off remotely by controlling the connection to an external power source, ensuring zero standby power consumption through a clock signal generating unit, signal transmitting unit, signal receiving unit, rectifying and filtering unit, switch unit, and control unit, which determine the mode of operation based on signal persistence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrical equipment is kept in standby mode to allow remote control functionality, then the equipment can be quickly restarted, but power consumption continues during standby
Solution Approach 1:
The patent extracts the power consumption function during standby by completely disconnecting the power supply from the electrical equipment. The remote control signal is used to trigger a complete power cycle (shutdown and restart) rather than maintaining a standby state, thereby eliminating continuous power consumption while preserving remote operation capability.
Solution Approach 2:
The system uses periodic action by shutting down the equipment completely and only activating it when a remote control signal is received. This transforms continuous operation with periodic standby into discrete periodic activation, where the equipment operates only when needed and remains completely powered off otherwise, eliminating standby power consumption.
2Loss of energy
If the electrical equipment is completely shut off to eliminate standby power consumption, then energy efficiency is improved, but the equipment cannot be remotely controlled
Solution Approach 1:
The patent introduces an intermediary mechanism - the remote control signal reception circuit and power supply control circuit - that enables the equipment to wake up from complete shutdown. The equipment remains powered off to eliminate standby consumption, but the intermediary circuits allow it to receive remote signals and restart when needed, bridging the gap between complete shutdown and remote controllability.
3Reliability
If the power supply remains connected to maintain equipment functionality, then the equipment is always operational, but continuous power consumption occurs
Solution Approach 1:
The patent applies dynamics by making the power supply state changeable rather than static. The power supply dynamically transitions between connected and disconnected states based on operational needs. The equipment is fully operational when needed (high reliability) and completely powered off when not in use (zero energy loss), eliminating the need for continuous connection.

Data Source
AI summary
Electrical equipment includes a power supply unit, a signal receiving unit, a rectifying and filtering unit, a switch unit, and a control. The rectifying and filtering unit rectifies and filters remote signals received by the signal receiving unit to generate first voltage signals. The switch unit connects the power supply unit to an external power in response to receiving the first voltage signals. The control identifies a current mode of the electrical equipment and determines whether the first voltage signal persists longer than a predetermined time or not. The control outputs a second voltage signals in response to the duration time of the first voltage signals being greater than the predetermined time. The switch unit further connects the power supply unit to the external power according to the first voltage signal and the second voltage signal to start the electrical equipment.
