Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If conventional digital forensic technology based on physical storage is used, then it can collect data from device storage, but it cannot effectively collect wireless communication data in the in-vehicle infotainment environment

Engineering Contradiction:

Improvedigital evidence collectionVSAvoidapplicability to wireless communication environment

Core Design Contradiction:

Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent segments the digital forensic collection process into three distinct data sources: communication section data from wireless interactions, first device data from the infotainment system's physical storage, and second device data from the user terminal's physical storage. This segmentation allows each data type to be collected using appropriate methods while maintaining overall forensic completeness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a universal digital forensic framework that can handle multiple data types and communication protocols simultaneously. The system is designed to collect and analyze data from diverse sources including wireless communications, infotainment system storage, and user terminal storage, making it adaptable to various in-vehicle infotainment environments regardless of specific hardware or software configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If wireless communication is enabled in in-vehicle infotainment systems, then more services and data access are available, but driver personal information becomes exposed to cybersecurity threats

Engineering Contradiction:

Improveservice availabilityVSAvoidcybersecurity threats to personal information

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent performs preliminary digital forensic analysis by collecting and analyzing communication section data, device data, and artifacts before cybercrimes can occur or escalate. The system proactively identifies security threats, unauthorized access patterns, and potential vulnerabilities in wireless communications between the infotainment system and user terminals, enabling preventive security measures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where collected data from wireless communications and device operations is continuously analyzed to verify artifacts and detect anomalies. The system compares communication patterns, device states, and user behaviors to identify deviations that may indicate cybersecurity threats, providing continuous monitoring and alerting to protect driver personal information.

Inventive Principle:

Principle #23Feedback

3Loss of information

If multiple data collection methods are implemented for different specification information, then comprehensive digital evidence can be gathered, but the system complexity increases

Engineering Contradiction:

Improvecompleteness of digital evidenceVSAvoiddata collection system

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent divides the complex data collection process into three manageable segments: collecting communication section data from wireless interactions, collecting first device data from the infotainment system's physical storage, and collecting second device data from the user terminal's physical storage. Each segment has its own collection methods tailored to the specific data type and source, reducing overall system complexity while maintaining comprehensive evidence gathering.
