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, a sensor unit, and a controller to measure and determine if a predetermined control condition is met, cutting off power supply when the condition is satisfied and resuming it when not, thereby reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If power is continuously supplied to the electronic product, then the load can operate whenever needed, but unnecessary power consumption occurs due to standby power when the load is not operating

Engineering Contradiction:
Improvestandby power consumptionVSAvoidload operation availability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The controller predicts future load operation needs based on historical operation patterns and user behavior data, and proactively supplies power before the load is actually needed. This preliminary power supply action eliminates standby power consumption gaps while ensuring the load is ready to operate when needed, resolving the contradiction between energy loss and operation availability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors load operation status, temperature conditions, and user interaction patterns, then uses this feedback to dynamically adjust power supply timing. The controller learns from historical data and refines its predictions, optimizing the balance between reducing standby power consumption and maintaining load availability based on actual usage patterns.

Inventive Principle:
Principle #23Feedback

2Loss of energy

If power is cut off when control condition is satisfied, then power consumption is reduced, but the electronic product cannot respond quickly when the load needs to operate again

Engineering Contradiction:
Improvepower consumptionVSAvoidresponse speed
Core Design Contradiction:
Loss of energyVSSpeed

Solution Approach 1:

The controller predicts when the load will need to operate next based on historical patterns and user behavior, and restores power proactively before the actual need arises. This preliminary power restoration action eliminates delays that would occur with traditional on-demand power supply, ensuring quick response while maintaining reduced power consumption during idle periods.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts power supply timing based on learned operation patterns and changing user behavior. Rather than using fixed timing or simple threshold-based control, the system adapts its power management strategy in real-time, optimizing the balance between power consumption and response speed according to actual usage dynamics.

Inventive Principle:
Principle #15Dynamics

3Speed

If the controller continuously monitors the control condition, then the load can be activated immediately when needed, but power consumption increases due to continuous monitoring

Engineering Contradiction:
Improveload activation speedVSAvoidmonitoring power consumption
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

Instead of continuous monitoring, the controller uses periodic sampling of sensor data combined with predictive algorithms. The system monitors at optimized intervals based on learned patterns, reducing monitoring power consumption while maintaining accurate prediction of load operation needs. This periodic monitoring approach eliminates the energy waste of continuous monitoring while preserving quick activation capability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses historical operation data and environmental sensor data to self-predict when power will be needed, eliminating the need for continuous active monitoring. The controller learns from past patterns and autonomously determines optimal power supply timing, reducing monitoring energy consumption while maintaining accurate load activation timing through intelligent prediction rather than constant surveillance.

Inventive Principle:
Principle #25Self-service

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.
