Solution Overview

Problem

Short-range wireless communication functions activated for extended periods lead to increased power consumption due to continuous radio wave transmission and reception.

Innovation Solution

A communication control method that utilizes a change in state or operation of another device as a trigger to initiate short-range wireless communication, reducing unnecessary power consumption by controlling the reception of announcement signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the short-range wireless communication function is activated for a long time to ensure communication availability, then the communication reliability is improved, but the power consumption increases

Engineering Contradiction:

Improvecommunication availabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal performs waiting for reception of announcement signals periodically at specific intervals rather than continuously. The waiting operation is triggered by notifications from objects indicating changed operation or state, creating a periodic communication pattern that balances availability with power conservation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses notifications from objects about their own state changes to automatically trigger the terminal's waiting for reception operation. This self-service mechanism eliminates the need for continuous monitoring while ensuring communication is initiated when relevant events occur.

Inventive Principle:

Principle #25Self-service

2Speed

If the terminal continuously waits for reception of announcement signals to establish short-range wireless communication at any time, then the communication speed is improved, but the power consumption increases

Engineering Contradiction:

Improvecommunication establishment speedVSAvoidpower consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The terminal performs waiting for reception periodically triggered by notifications from objects rather than continuously. This periodic operation maintains communication readiness when needed while significantly reducing power consumption compared to continuous waiting.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The terminal performs waiting for reception in advance of actual communication needs by triggering on notifications from objects about state changes. This preliminary action ensures communication can be established quickly when announcement signals are transmitted without requiring continuous monitoring.

Inventive Principle:

Principle #10Preliminary action

AI summary

By communicating with an object having a communication function and having a function of monitoring a change in operation or state of the object, it is determined whether a notification indicating that the operation or the state managed by the object has changed has been received (S301), and when it is determined that the notification has been received, waiting for reception of an announcement signal for establishing short-range wireless communication with an apparatus different from the object is performed (S302).
