Solution Overview

Problem

Existing on-vehicle communication technologies do not adequately control communication channels based on the self-driving level and vehicle speed, potentially leading to insecure data transmission and visibility issues.

Innovation Solution

An on-vehicle communication device that acquires vehicle speed and self-driving level information to determine whether to enable or disable high-confidential communication channels and adjust the visibility of displayed information based on these factors, ensuring secure data transmission and reduced risk of information leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If communication channels are enabled for driver interaction with external devices, then driver convenience and operational capability are improved, but security risk and information leakage potential increase

Engineering Contradiction:

Improvedriver operational capabilityVSAvoidcommunication security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting communication channel accessibility based on vehicle speed parameters. When vehicle speed exceeds a threshold, the system automatically restricts access to high-confidential communication channels, thereby adapting security parameters to current operational conditions and resolving the contradiction between ease of operation and communication security.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If high-confidential communication channels are always accessible, then data transmission capability is improved, but risk of information exposure to external observers increases

Engineering Contradiction:

Improvedata transmission capabilityVSAvoidinformation exposure risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamics by making communication channel accessibility dynamic rather than static. The system continuously monitors vehicle speed and automatically adjusts the accessibility of high-confidential communication channels in real-time, allowing full data transmission capability when safe and restricting it when vehicle speed indicates potential exposure risk.

Inventive Principle:

Principle #15Dynamics

3Reliability

If communication restrictions are imposed based on vehicle speed, then security and confidentiality are improved, but communication availability and operational flexibility deteriorate

Engineering Contradiction:

Improvecommunication confidentialityVSAvoidcommunication availability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent resolves this contradiction through parameter changes by using vehicle speed as a dynamic threshold parameter. Communication restrictions are not imposed universally but only when vehicle speed exceeds the predetermined threshold, thereby maintaining communication availability and operational flexibility during normal driving conditions while ensuring confidentiality when speed-based exposure risk arises.

Inventive Principle:

Principle #35Parameter changes
