Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If IP-based communication is used for vehicle control, then transmission speed and data capacity are improved, but communication stability deteriorates due to frequent IP address changes

Engineering Contradiction:
Improvetransmission speedVSAvoidcommunication stability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent introduces an intermediary mechanism (PDU session management and IP address binding) that decouples the relationship between vehicle mobility and communication stability. The system maintains stable logical connections and bound IP addresses even when physical IP addresses change, allowing fast IP-based communication while preserving reliability through the intermediary layer.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If SMS protocol is used for vehicle control, then communication stability is improved, but transmission speed and data capacity deteriorate

Engineering Contradiction:
Improvecommunication stabilityVSAvoidtransmission speed
Core Design Contradiction:
ReliabilityVSSpeed

Solution Approach 1:

The patent merges the advantages of both SMS and IP-based communication systems. It uses IP-based communication for fast data transmission while incorporating SMS-like connection management mechanisms (PDU sessions, authentication) to ensure stability and reliability, creating a hybrid approach that combines the strengths of both protocols.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If separate development and management is performed for each service user, then customization is improved, but system complexity and maintenance costs increase

Engineering Contradiction:
Improveservice customizationVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal platform architecture that serves multiple service users through standardized interfaces and modular components. The system provides multi-functional capabilities including vehicle control, monitoring, and management through a common infrastructure, allowing different users to access customized services without requiring separate system developments, thereby reducing overall complexity while maintaining adaptability.

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

4Reliability

If SMS protocol is used for vehicle control, then security is improved through protocol simplicity, but cost increases and transmission time extends

Engineering Contradiction:
ImprovesecurityVSAvoidtransmission time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the fundamental parameters of communication by transitioning from SMS protocol to IP-based communication with enhanced security mechanisms. It implements authentication, encryption, and secure session management at the IP layer, maintaining security while dramatically reducing transmission time from 10-14 seconds to near-real-time speeds.

Inventive Principle:
Principle #35Parameter changes
