Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is transmitted through packet switching networks, then network flexibility and routing options are improved, but communication capacity adjustment becomes difficult and user available capacity decreases
Solution Approach 1:
The patent segments the network into two distinct types: packet switching networks for flexible routing and line switching networks for guaranteed capacity. Distribution devices divide data transmission tasks between these two network segments based on policy information, allowing each segment to fulfill its specific function without compromising the other.
Solution Approach 2:
Distribution devices act as intermediary components between service providing devices and end users. These intermediaries capture data, determine the appropriate network type based on policy information, and route data accordingly. This intermediary layer enables intelligent traffic management and capacity allocation without requiring changes to the underlying network infrastructure.
2Quantity of substance
If optical burst transfer technology is implemented, then communication capacity is improved for selected users, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent creates a universal framework that supports both packet switching and line switching networks through common distribution devices. These devices can handle multiple network types and transmission protocols, providing multi-functionality without requiring separate specialized infrastructure for each network type.
Solution Approach 2:
The system implements feedback mechanisms where distribution devices monitor network conditions, user requirements, and policy information to dynamically adjust data routing decisions. This feedback loop enables the system to adapt to changing conditions while maintaining manageable complexity through automated decision-making based on predefined policies.
3Productivity
If data is captured and aggregated based on policy information, then communication capacity allocation efficiency is improved, but processing time and operational complexity increase
Solution Approach 1:
Policy information is established in advance before data transmission occurs. Distribution devices use these pre-defined policies to make rapid routing decisions without requiring complex real-time analysis. This preliminary action approach allows efficient capacity allocation while minimizing processing time during actual data transmission.

AI summary
Distribution devices are each connected to a single or a plurality of line switching networks and a single or a plurality of packet switching networks, selects either the line switching network or the packet switching network as the distribution destination on the basis of distribution policy information in a case where data to which the service providing device or the calculation device is set as a transmission destination, and transmits the received data to the selected switching network is received, and the distribution device captures the received data on the basis of the aggregation policy information and transmit the data to the service providing device or the calculation device corresponding to the transmission destination of the captured data in a case where data transmitted by the other distribution device is received from the line switching network or the packet switching network.
