Load Power Switching Control for Standby Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic products continue to consume unnecessary power even when a predetermined control condition is satisfied, leading to standby power consumption, as they are continuously supplied with power regardless of the operational need.
Innovation Solution
An apparatus and method that include a power switching unit, sensor unit, and controller to monitor and control power supply based on predetermined conditions, cutting off power when the condition is met and resuming supply when it is not, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If power is continuously supplied to electronic products, then the loads can operate whenever needed, but unnecessary power consumption occurs during standby periods
Solution Approach 1:
The controller predicts future load operation needs based on historical operation data and user patterns before actually needing the load. This preliminary prediction allows the system to prepare for upcoming operation periods, ensuring reliability while avoiding unnecessary standby power consumption during predicted idle periods.
Solution Approach 2:
Instead of continuous power supply, the system implements periodic power supply based on predicted operation cycles. The controller periodically wakes up to check predicted needs, supplies power only during predicted operation windows, and remains in low-power mode during predicted idle periods, converting continuous action into efficient periodic action.
2Loss of energy
If power is cut off when control conditions are satisfied, then standby power consumption is reduced, but the load cannot respond quickly when conditions change
Solution Approach 1:
The controller performs preliminary prediction of load operation needs using historical data and user patterns before actual operation is required. This advance preparation allows the system to wake up and supply power in advance of actual needed operation, maintaining fast response times while enabling power cutoff during predicted idle periods.
Solution Approach 2:
The system continuously monitors actual load operation vs. predicted operation, using this feedback to refine future predictions. When the load actually operates differently from predictions, the controller learns from this discrepancy and adjusts future prediction accuracy, ensuring both energy efficiency and reliable response when conditions change.

AI summary
Provided is an apparatus and method for reducing power consumption of an electronic product. The apparatus and method reduces unnecessary power consumption by cutting off power for driving a load if a predetermined control condition is satisfied in an electronic product operating for a long time. In the electronic product operating for a long time, power for driving the load is cut off to prevent waste of the power if the predetermined control condition is satisfied, and the load is driven only when the predetermined control condition is not satisfied, thereby efficiently reducing the power consumption of the electronic product.
