Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hierarchical network architecture with superordinate networks is used to connect multiple sub-networks, then data transfer between sub-networks can be implemented, but the system configuration complexity increases and fabrication cost increases
Solution Approach 1:
The patent merges the superordinate network N110 and data transfer systems DT104-DT106 into a direct peer-to-peer connection between sub-networks N101-N103. Each sub-network station (STN111-STN13n) can directly access shared memories in other sub-networks without intermediate transfer systems, eliminating hierarchical complexity while maintaining data transfer capability.
Solution Approach 2:
The patent extracts and removes the superordinate network N110 and data transfer systems DT104-DT106 from the system architecture. By eliminating these intermediate components, the system achieves direct communication between sub-networks, reducing configuration complexity and fabrication cost while preserving essential data transfer functionality.
2Reliability
If data transfer through superordinate network and additional data transfer systems is used, then data can be transferred between sub-networks, but the data transfer rate decreases
Solution Approach 1:
The patent removes the superordinate network N110 and data transfer systems DT104-DT106 that caused data transfer delays. By establishing direct connections between sub-network stations, data can be transferred without intermediate routing steps, significantly increasing the data transfer rate while maintaining reliability.
3Reliability
If multiple data transfer systems and superordinate networks are provisioned, then data transfer between sub-networks is enabled, but fabrication cost increases and maintenance cost increases
Solution Approach 1:
The patent extracts and eliminates the superordinate network N110 and data transfer systems DT104-DT106, reducing the number of hardware components that need to be manufactured and installed. This directly reduces fabrication cost while maintaining data transfer capability through direct peer-to-peer connections.
Solution Approach 2:
The patent merges the functions of superordinate network N110 and data transfer systems DT104-DT106 into direct communication paths between sub-network stations. By combining these separate components into integrated direct connections, the system reduces both fabrication cost and maintenance cost while preserving data transfer functionality.
4Reliability
If hierarchical network architecture with multiple components is used, then data transfer between sub-networks can be implemented, but maintenance expense increases
Solution Approach 1:
The patent removes the superordinate network N110 and data transfer systems DT104-DT106, eliminating the components that require maintenance. By reducing the total number of system components, maintenance expense is directly reduced while data transfer capability is maintained through simplified direct connections.
