Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate control devices are used for circuit-switching and packet-switching networks, then each network can be independently controlled, but the technical and financial effort for conversion and the complexity of the system increase significantly
Solution Approach 1:
The patent combines separate control devices for circuit-switching and packet-switching networks into a single unified control device. This unified controller manages both network types through a common architecture, reducing the number of separate components while maintaining the ability to independently control each network type through dedicated control modules within the unified structure.
Solution Approach 2:
The unified control device is designed with multi-functional capabilities to handle both circuit-switching and packet-switching operations. It incorporates universal interfaces and protocols that can manage different network types through a single device, eliminating the need for separate specialized controllers and reducing overall system complexity.
2Adaptability or versatility
If separate control devices are used for circuit-switching and packet-switching networks, then each network maintains its specific requirements, but the conversion costs and re-implementation of value-added services increase
Solution Approach 1:
The unified control device provides universal control capabilities that can adapt to both circuit-switching and packet-switching networks. It implements a common control architecture with protocol converters and adaptation layers that enable the same device to serve multiple network types, eliminating the need for separate control infrastructure and reducing conversion costs.
Solution Approach 2:
The patent introduces intermediary components within the unified control device, such as protocol converters and adaptation layers, that mediate between the common control architecture and the specific network requirements. These intermediaries enable seamless operation across different network types without requiring complete re-implementation of control logic for each network.
3Device complexity
If a unified control device is implemented, then conversion costs and complexity are reduced, but the control device must handle very different circuit-switching and packet-switching functions simultaneously
Solution Approach 1:
The unified control device is segmented into distinct control modules, each specialized for either circuit-switching or packet-switching functions. This modular architecture allows the device to handle different network types through dedicated modules while maintaining a unified overall structure, reducing the complexity of managing diverse functions within a single device.
Solution Approach 2:
The patent employs intermediary components within the unified control device that translate and adapt between circuit-switching and packet-switching protocols. These intermediaries enable the control device to manage very different functions simultaneously by providing a translation layer that harmonizes the operational requirements of both network types.
4Ease of manufacture
If separate control devices are used, then service implementation is straightforward for each network type, but the ability to provide seamless services across both network types is compromised
Solution Approach 1:
The unified control device merges the control functions for both network types into a single coordinated system. This integration enables seamless service delivery across circuit-switching and packet-switching networks by allowing the controller to manage service continuity and coordinate operations across both network types through a unified control logic.
