Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical network communication and address mapping are used for interconnection among different video monitoring systems, then network intercommunication is achieved, but network independence and security are compromised
Solution Approach 1:
The patent introduces a video gateway as an intermediary device that enables communication between different video monitoring systems without direct physical network connection. The gateway translates and forwards video data packets between isolated networks, achieving intercommunication while maintaining network independence and security boundaries.
Solution Approach 2:
The system segments different video monitoring networks into isolated units that can be independently managed and secured. Each network maintains its own IP address planning and security policies, while the video gateway provides controlled access points for necessary intercommunication without merging the networks.
2Adaptability or versatility
If video resources from different systems are interconnected through physical networks, then resource sharing is enabled, but network complexity and security risks increase
Solution Approach 1:
The video gateway serves as a mediator that handles the complexity of resource sharing between different systems. It manages IP address translation, video data formatting, and access control, allowing resource sharing without requiring complex configuration changes in the underlying networks.
Solution Approach 2:
The system creates virtual copies of video resources through the gateway, allowing multiple systems to access and share video data without direct physical connections. The gateway replicates and forwards video streams to authorized systems, enabling resource sharing while maintaining network isolation.
3Reliability
If different video monitoring systems are built with different standards and IP address planning, then system independence is maintained, but interconnection and resource sharing become difficult
Solution Approach 1:
The video gateway dynamically changes IP address parameters and data formatting to accommodate different video monitoring system standards. It performs IP address translation and protocol conversion, allowing systems with different addressing schemes to communicate without losing their independence or standardization benefits.
