Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-party video calls are established between IP terminal devices and telephone network devices, then video service capability is improved, but communication cost increases
Solution Approach 1:
The patent segments the video call establishment process into distinct phases: initial video call setup between IP terminal devices, followed by separate media channel establishment with telephone network devices. This segmentation allows optimized resource allocation for each phase, reducing overall communication cost while maintaining video service capability.
Solution Approach 2:
The patent introduces a gateway as an intermediary component that bridges the IP network and telephone network. The gateway mediates channel combination and coordinate transformation between different network protocols, enabling video calls between networks while optimizing resource usage and reducing communication costs through intelligent routing.
2Productivity
If video channels are combined between telephone network and IP network, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The gateway serves as an intermediary that handles the complex channel combination process between telephone network video channels and IP network video channels. It performs coordinate transformation and protocol adaptation, simplifying the interface between networks while maintaining high communication efficiency through optimized data routing.
Solution Approach 2:
The patent applies parameter changes by transforming coordinate systems and adjusting communication parameters during channel combination. The gateway dynamically adjusts transmission parameters, encoding formats, and synchronization settings to optimize video stream integration while managing system complexity through automated parameter management.
