Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of users increases, then the network capacity and service coverage are improved, but the number of FXC switches in the intermediate layer increases, leading to higher network costs
Solution Approach 1:
The patent merges multiple FXC switch functions into fewer switches by optimizing the connection structure. Specifically, it reconfigures the network topology to reduce the number of intermediate layer FXC switches while maintaining the ability to handle increased user traffic through more efficient routing and connection management.
Solution Approach 2:
The patent transforms the problem from managing more switches in the traditional layered structure to optimizing connections within a reconfigured topology. By changing the dimensional arrangement of connections and using advanced switching fabric designs, it achieves higher capacity with fewer physical switches.
2Productivity
If more FXC switches are deployed in the intermediate layer to accommodate more users, then the network can handle more connections, but the network cost increases
Solution Approach 1:
The patent changes key parameters of the network architecture including the number of intermediate layer switches, connection probabilities, and routing configurations. By optimizing these parameters mathematically, it achieves higher connection handling capacity with reduced switch count, directly lowering network cost while maintaining productivity.
3Quantity of substance
If the number of FXC switches in the intermediate layer is reduced, then the network cost is lowered, but the ability to accommodate more users may be compromised
Solution Approach 1:
The patent performs preliminary optimization of the network topology and connection configurations before deploying the reduced number of switches. By pre-calculating optimal connection paths and routing strategies, the system ensures that even with fewer switches, the network can effectively accommodate the required number of users without performance degradation.
