Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If wireless LAN communication is prioritized to reduce communication costs, then communication cost is reduced, but security for critical vehicle functions may be compromised

Engineering Contradiction:

Improvecommunication costVSAvoidsecurity for critical vehicle functions

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent divides communication services into different segments based on security requirements and immediacy needs. Critical vehicle functions are routed through virtual routers associated with cellular communication (higher security), while non-critical services use wireless LAN (lower cost). This segmentation allows simultaneous optimization of both cost and security for different service types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different security qualities are assigned to different communication services based on their specific requirements. The system applies local quality by configuring virtual routers with appropriate security levels and routing policies for each service, rather than applying a uniform security approach to all communications.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple virtual routers are used to handle different services with varying security needs, then service customization is improved, but device complexity increases

Engineering Contradiction:

Improveservice customizationVSAvoidvirtual router system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication control apparatus implements a universal virtual router system that can handle multiple services with different requirements through a standardized framework. Each virtual router follows the same structural pattern and can be configured for different services, allowing the system to serve multiple functions while maintaining manageable complexity through consistency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The virtual router system is designed to be dynamic, allowing routing tables and service configurations to be adjusted based on vehicle conditions and service requirements. The system can dynamically select appropriate virtual routers and routing paths, providing adaptability without requiring fixed complex hardware configurations.

Inventive Principle:

Principle #15Dynamics

3Productivity

If routing tables are dynamically adjusted based on vehicle conditions, then communication efficiency is improved, but control complexity increases

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidrouting control complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms that monitor vehicle conditions and communication states, then automatically adjust routing tables accordingly. The communication control apparatus receives feedback about service requirements and network conditions, and uses this information to dynamically optimize routing decisions, improving efficiency while keeping control logic systematic.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary configuration of virtual routers and routing policies based on predefined service requirements and vehicle conditions. By pre-establishing routing rules and virtual router configurations, the system reduces the complexity of real-time control decisions while maintaining dynamic adaptability through pre-planned routing strategies.

Inventive Principle:

Principle #10Preliminary action
