Engineering Contradiction Analysis
1Adaptability or versatility
If two data vortex interconnection networks are connected in parallel to achieve bidirectional operation, then bidirectional data flow is enabled, but device complexity increases and throughput is reduced
Solution Approach 1:
The patent merges forward and reverse data flow paths into a single Data Vortex network by enabling bidirectional operation at each switching node. Instead of using separate parallel networks, the invention combines both directions through shared nodes with bidirectional links, reducing the total number of nodes and optical components while maintaining full bidirectional functionality.

Each switching node in the patent is designed to handle both forward and reverse data flow through bidirectional links. The nodes perform multiple functions by routing packets in either direction based on control signals, eliminating the need for separate dedicated nodes for each direction and thereby reducing overall system complexity.
