Solution Overview

Problem

Existing electronic devices with wireless communication functions face challenges in optimizing power consumption during discontinuous reception modes, particularly in low-power wide-area communication systems, leading to inefficient power management.

Innovation Solution

The electronic device employs a processor to adjust the waiting interval for data reception by performing a shortening process in response to a certain notification and an extension process based on specific conditions, switching between extended discontinuous reception and discontinuous reception cycles to optimize power usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If the waiting interval is extended to reduce power consumption, then power savings increase, but data reception responsiveness deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoiddata reception delay

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The waiting interval is made dynamic rather than fixed. The processor adjusts the waiting interval between communication attempts based on received signals and communication conditions, allowing the system to optimize between power consumption and data reception responsiveness in real-time

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of waiting interval based on different communication scenarios. When a signal indicating data transmission is received, the waiting interval is shortened to improve responsiveness; otherwise, it is extended to save power

Inventive Principle:

Principle #35Parameter changes

2Productivity

If the waiting interval is shortened to improve data reception responsiveness, then communication efficiency improves, but power consumption increases

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The waiting interval parameter is adjusted based on communication needs. The system shortens the interval when data transmission is detected to improve communication efficiency, and extends it during idle periods to reduce power consumption

Inventive Principle:

Principle #35Parameter changes

3Loss of energy

If discontinuous reception mode is used to reduce power consumption, then energy efficiency improves, but communication reliability deteriorates

Engineering Contradiction:

Improvepower consumptionVSAvoidcommunication reliability

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The system uses feedback from received signals to adjust its reception strategy. When a signal indicating potential data transmission is detected, the system increases reception frequency to ensure reliable data capture, while maintaining power savings during periods without such signals

Inventive Principle:

Principle #23Feedback

AI summary

An electronic device includes a processor and a communicator that communicates with an external communication device via a server. The communicator discontinuously awaits data reception from the server with a predetermined waiting interval. The processor performs a shortening process to shorten the waiting interval in response to the communicator receiving a certain notification via the server, and after performing the shortening process, performs an extension process to extend the waiting interval in response to a certain condition being satisfied.
