Solution Overview

Problem

The authenticity of vehicle data stored in automobile manufacturer servers cannot be ensured due to the ability of manufacturers to change or delete data at will, and direct data reading from these servers may result in incomplete or insufficient data due to bandwidth limitations and damaged communication modules.

Innovation Solution

A data reading method and apparatus that establishes a communication link between a vehicle-mounted TBOX and a data reading terminal using USB or wireless local area networks, incorporating security authentication and data encryption to ensure data integrity and authenticity, and utilizes a custom file format to enhance security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If data is obtained from automobile manufacturer servers, then data access convenience is improved, but data authenticity cannot be ensured due to manufacturers' ability to change or delete data at will

Engineering Contradiction:
Improvedata access convenienceVSAvoiddata authenticity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a TBOX as an intermediary device between the vehicle and the data reading terminal. The TBOX stores data locally and provides direct reading capability, mediating between the need for convenient data access and the requirement for authentic data. This eliminates dependency on manufacturer servers while ensuring data authenticity through local storage and controlled access mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a local copy of vehicle data in the TBOX, which can be read directly without accessing the original server. This copy enables convenient data access while maintaining authenticity through local verification mechanisms, bypassing the reliability issues of server-based data storage.

Inventive Principle:
Principle #26Copying

2Productivity

If data reading time is reduced, then productivity is improved, but data security may be compromised due to faster access

Engineering Contradiction:
Improvedata reading speedVSAvoiddata security
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements preliminary security authentication and permission verification before data reading operations. The TBOX checks user credentials, validates reading permissions, and establishes secure communication channels in advance. This preliminary action ensures data security is maintained while enabling fast data transfer during the actual reading process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies different quality levels to different parts of the data reading system. Security-critical functions (authentication, permission checking) use rigorous verification processes, while the actual data transfer uses high-speed protocols. This local differentiation maintains security where needed while maximizing reading speed where appropriate.

Inventive Principle:
Principle #3Local quality

3Reliability

If security authentication is implemented, then data security is improved, but device complexity increases

Engineering Contradiction:
Improvedata securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functional authentication mechanisms within the TBOX that handle multiple security requirements (user verification, permission checking, data encryption, communication security) through integrated security modules. This universal security framework provides comprehensive protection while avoiding the complexity of separate independent security systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A data reading method is applicable to the vehicle-mounted TBOX, and a link is established between the vehicle-mounted TBOX and a data reading terminal. Based on the link, the method includes: the vehicle-mounted TBOX receives a connection request from the data reading terminal. The vehicle-mounted TBOX sends a connection response to the connection request to the data reading terminal, to establish a communication connection with the data reading terminal. The data reading terminal sends a data reading instruction to the vehicle-mounted TBOX after the communication connection is established, and the vehicle-mounted TBOX receives the data reading instruction from the data reading terminal. The vehicle-mounted TBOX sends target data to the data reading terminal in response to the data reading instruction, to implement reading of the target data.
