Solution Overview

Problem

Communication devices struggle to efficiently connect with reliable partners in wireless networks due to insufficient wireless resources and unreliable relay devices, leading to degraded communication quality and convenience.

Innovation Solution

A communication system where vehicles acquire conditions for communication using a second method from a base station, enabling them to select and connect with suitable relay devices based on geographical range, capacity, reliability, and timing, thereby optimizing communication paths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a vehicle connects to another vehicle using a different communication method to offload data, then wireless resource utilization is improved, but the area where connection is possible becomes extremely limited

Engineering Contradiction:
Improvewireless resource utilizationVSAvoidconnection area
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent introduces a base station as an intermediary that provides condition information about relay vehicles. This mediator enables vehicles to identify suitable relay partners by receiving pre-evaluated condition information (communication capability, location, load status) from the base station, thereby expanding the effective connection area while maintaining efficient resource utilization through informed partner selection

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a vehicle selects a relay vehicle based on proximity, then connection establishment is simplified, but the relay vehicle may not be capable of communicating with the predetermined device

Engineering Contradiction:
Improveconnection establishmentVSAvoidcommunication capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The base station performs preliminary evaluation and publishes condition information about relay vehicles before actual connection establishment. This preliminary action includes assessing communication capabilities, location, and load status, allowing vehicles to make informed selection decisions that ensure both ease of connection and reliability of the relay path

Inventive Principle:
Principle #10Preliminary action

3Speed

If a communication device connects to another device without recognizing its connectability to the predetermined device, then connection speed is improved, but communication quality may be degraded due to unreliable relay devices

Engineering Contradiction:
Improveconnection speedVSAvoidcommunication quality
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system implements feedback through the base station that continuously monitors and publishes condition information about relay vehicles. This feedback mechanism provides real-time information about communication capability, location, and load status, enabling vehicles to quickly identify reliable partners while maintaining high connection speed through pre-evaluated information

Inventive Principle:
Principle #23Feedback

AI summary

A communication device that performs communication wirelessly receives by using a first communication method, from a first another device, information regarding a condition for communication in a second communication method within a geographical range where communication with the first another device is possible, the second communication method being different from the first communication method, and selects a second another device that performs the communication in the second communication method, based on the information regarding the condition.
