Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If existing vehicle bus protocols are used, then device compatibility is maintained, but data transmission speed and bandwidth are limited

Engineering Contradiction:

Improvedata transmission speedVSAvoidprotocol compatibility

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The patent introduces a gateway device as an intermediary between the existing vehicle bus protocol and modern high-speed communication protocols. The gateway translates and forwards data packets between protocols, enabling fast data transmission while maintaining compatibility with legacy vehicle systems. This resolves the contradiction by mediating between the old protocol constraints and new speed requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication system is segmented into multiple protocol layers, with different protocols used for different communication needs. Critical safety data uses high-speed protocols where available, while non-critical data maintains compatibility with traditional bus protocols. This segmentation allows the system to achieve high transmission speeds for important data without sacrificing overall protocol compatibility.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If computational components are installed in vehicles, then functionality is enhanced, but security risks from unauthorized access increase

Engineering Contradiction:

Improvecomponent functionalityVSAvoidsystem security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements preliminary binding of computational components to specific vehicles during the installation process. The gateway device creates binding records that permanently associate each component with its authorized vehicle identifier. This preliminary security measure prevents unauthorized components from accessing the vehicle network, thereby maintaining reliability while allowing functional enhancement.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors communication requests and verifies component bindings before allowing data transmission. The gateway device checks each data packet against the binding records, providing real-time feedback by blocking unauthorized access attempts. This feedback mechanism ensures security while permitting legitimate functional expansions.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If data sharing between vehicles is enabled, then interoperability is improved, but data security and privacy protection become more difficult

Engineering Contradiction:

Improvevehicle interoperabilityVSAvoiddata security risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements selective data sharing where different types of data are handled differently based on their sensitivity. Non-sensitive operational data is shared freely to improve interoperability, while sensitive personal or security-critical data remains protected and bound to specific vehicles. This local quality approach allows interoperability benefits without exposing the system to security risks.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The gateway device serves as an intermediary that filters and controls data sharing between vehicles. It anonymizes and aggregates data before transmission, removing personally identifiable information while preserving useful operational patterns. This intermediary function enables interoperability through data sharing while protecting security and privacy through automated filtering.

Inventive Principle:

Principle #24Intermediary (Mediator)
