Wireless Communication Device Setting Synchronization

Solution Overview

Problem

Current short-range wireless communication technologies, such as Bluetooth BLE, face inefficiencies when transmitting multiple types of information, leading to increased power consumption and processing load due to repeated data exchange even when settings have not changed.

Innovation Solution

Implementing a method where devices use discrimination information, such as bitmaps, to determine which settings have changed since the last communication, allowing only updated information to be synchronized, thereby reducing unnecessary communication and data exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If multiple types of information are transmitted between devices, then communication completeness is improved, but current consumption and processing load increase

Engineering Contradiction:

Improvecommunication completenessVSAvoidcurrent consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent extracts only the changed setting information from the complete set of information and transmits it to the other device. Instead of transmitting all setting information repeatedly, the system identifies and transmits only the specific portions that have changed, thereby maintaining communication completeness while reducing current consumption.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the setting information into multiple types or categories. By dividing the information into discrete segments, the system can selectively transmit only those segments that have changed, rather than transmitting the entire information set, thus reducing energy consumption while ensuring all necessary information is communicated.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If multiple types of information are transmitted between devices, then communication completeness is improved, but processing load increases

Engineering Contradiction:

Improvecommunication completenessVSAvoidprocessing load

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts only the changed setting information from the complete set of information and transmits it to the other device. Instead of transmitting all setting information repeatedly, the system identifies and transmits only the specific portions that have changed, thereby maintaining communication completeness while reducing current consumption.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the setting information into multiple types or categories. By dividing the information into discrete segments, the system can selectively transmit only those segments that have changed, rather than transmitting the entire information set, thus reducing energy consumption while ensuring all necessary information is communicated.

Inventive Principle:

Principle #1Segmentation

3Reliability

If all setting information is transmitted repeatedly, then data synchronization is ensured, but communication efficiency decreases

Engineering Contradiction:

Improvedata synchronizationVSAvoidcommunication efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies partial action by transmitting only the necessary portion of the information (i.e., only the changed settings) rather than the complete information set. This partial transmission approach maintains data synchronization reliability while improving communication efficiency by reducing redundant data exchange.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent extracts only the changed setting information from the complete set of information and transmits it to the other device. Instead of transmitting all setting information repeatedly, the system identifies and transmits only the specific portions that have changed, thereby maintaining communication completeness while reducing current consumption.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

According to an aspect of the present invention, a device capable of wireless communication includes a communicator configured to transmit and receive communication packets to and from other device, a memory configured to store one or more kinds of setting information, and a processor configured to determine whether or not at least one of the one or more kinds of setting information has been changed after the last communication with the other device, generate discrimination information indicating whether or not each of the one or more kinds of setting information has been changed, and control communication with the other device based on the discrimination information.
