Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each source is connected to every sink in the virtual space, then communication coverage is improved, but connection management complexity increases
Solution Approach 1:
The patent segments the virtual space into multiple zones with different connection rules. Instead of treating all sources and sinks uniformly, the system divides the communication environment into distinct regions (e.g., near-field and far-field zones) where different switching rules apply, thereby reducing the complexity of managing universal connections while maintaining comprehensive coverage.
Solution Approach 2:
The patent implements local switching rules that vary by virtual space zone. Each zone has customized connection parameters and switching behaviors tailored to its specific requirements. This allows the system to optimize connections locally in each zone rather than applying a uniform connection strategy across the entire virtual space, reducing overall management complexity.
2Reliability
If bandwidth is allocated to all real-time data streams, then communication quality is improved, but network resource consumption increases
Solution Approach 1:
The patent applies partial bandwidth allocation based on the importance and requirements of different data streams. Not all streams receive full bandwidth treatment; instead, the system allocates bandwidth selectively according to quality-of-service parameters, stream priority, and virtual zone requirements, ensuring adequate communication quality for critical streams while conserving network resources for less demanding streams.
Solution Approach 2:
The system dynamically adjusts bandwidth allocation parameters based on changing conditions in the virtual space, including user presence, data stream types, and network availability. By making bandwidth a variable parameter rather than a fixed allocation, the system optimizes the balance between communication quality and resource consumption in real-time.
3Ease of operation
If connection switching rules are simplified, then ease of operation is improved, but control precision over data stream interactions decreases
Solution Approach 1:
The patent implements automatic connection switching where the system autonomously determines which sources to connect to which sinks based on predefined virtual zone rules and current spatial relationships. This self-service approach eliminates manual configuration complexity while maintaining precise control through programmable switching logic that automatically adapts to changing virtual environment conditions.
Solution Approach 2:
The system continuously monitors the virtual space environment and uses this feedback to dynamically adjust connections. Position information, user presence detection, and stream quality metrics provide feedback loops that enable the switching mechanism to automatically refine connections, balancing ease of operation with precise control through automated adaptation.

AI summary
In one aspect, one or more real-time data stream connections that deliver a set of real-time data streams to a given network node are determined based at least in part on bandwidth capabilities of the given network node. In another aspect, for each of one or more recipient network nodes, a respective link over which to transmit a respective transmission set of one or more real-time data streams is determined. For each of the links, the respective link bandwidth is apportioned between one or more channels that are respectively allocated to the one or more real-time data streams in the respective transmission set.
