Engineering Contradictions & Design Principles
Engineering 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
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.
2Reliability
If SMS protocol is used for vehicle control, then communication stability is improved, but transmission speed and data capacity deteriorate
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.
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
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.
4Reliability
If SMS protocol is used for vehicle control, then security is improved through protocol simplicity, but cost increases and transmission time extends
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.
