Vehicle Information Transmission Apparatus with Grade-Based Access Control

Solution Overview

Problem

Conventional vehicle information transmission apparatuses lack secure access control and fail to manage communication failures and transmission timing effectively, leading to unauthorized access and missed critical information due to communication interference or terminal defects.

Innovation Solution

A vehicle information transmission apparatus with a storage unit for vehicle data, transmission grades, and user terminal grades, a control unit to manage access and transmission based on grades, and a transmission unit to send data to appropriate terminals, including prioritization and password-protected modes for secure and timely information delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all vehicle information is transmitted to all user terminals, then information completeness is improved, but security deteriorates because unauthorized access cannot be prevented

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent segments vehicle information into different types (general information, private information, semi-private information) and segments user terminals into different user groups (all users, specific users, authorized users only). This segmentation allows selective transmission of information to appropriate user groups, ensuring information completeness for authorized users while preventing unauthorized access to sensitive information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by assigning different transmission permissions to different pieces of vehicle information based on their sensitivity. General information (e.g., vehicle location, speed) is transmitted to all user terminals, while private information (e.g., engine diagnostics, fuel level) is transmitted only to authorized terminals. This ensures that each piece of information receives the appropriate level of access control.

Inventive Principle:
Principle #3Local quality

2Use of energy by moving object

If vehicle information is transmitted only upon user request, then energy consumption is reduced, but information timeliness deteriorates because critical information may not be transmitted during communication failures

Engineering Contradiction:
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent implements dynamic transmission control where the transmission behavior adapts based on communication status. During normal communication, information is transmitted upon user request to save energy. When communication failure is detected, the system dynamically switches to automatic transmission mode for critical information, ensuring reliability while minimizing energy consumption during normal operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent performs preliminary action by detecting communication failures in advance and proactively transmitting critical vehicle information to alternative terminals before complete communication breakdown occurs. This ensures that important information is delivered even when primary communication channels fail, while maintaining energy efficiency by only activating this mode when necessary.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If all vehicle information is transmitted at the same time, then information availability is improved, but transmission efficiency deteriorates because different information types require different transmission priorities

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The patent segments vehicle information into priority levels (high priority, medium priority, low priority) based on importance and urgency. Critical safety-related information is transmitted first, followed by important operational information, and finally general status information. This segmentation ensures all necessary information becomes available while optimizing transmission efficiency through prioritized delivery.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements periodic transmission for different types of vehicle information based on their update requirements. Critical information is transmitted periodically at high priority, while less time-sensitive information is transmitted at lower priority intervals. This ensures information availability for all necessary data while improving transmission efficiency by avoiding simultaneous transmission of all information types.

Inventive Principle:
Principle #19Periodic action
