Engineering Contradiction Analysis
1Reliability
If multiple unicast links are established between devices, then communication reliability and data rate are improved, but device complexity and management overhead increase
Solution Approach 1:
The patent merges multiple unicast link management functions into a single group link managed by a group ID. Instead of maintaining separate link states for each unicast connection between devices, the system combines these into one group-level link, reducing the number of link management operations from O(n) to O(1) where n is the number of devices in the group.
Solution Approach 2:
The group link serves multiple functions simultaneously: it enables communication between all devices in the group, provides unified link management, and supports both data transmission and link maintenance operations through a single interface, eliminating the need for separate mechanisms for each function.
2Device complexity
If group communication is implemented to reduce complexity, then device complexity is reduced, but communication reliability may deteriorate
Solution Approach 1:
The patent segments the group link management into two distinct layers: group-level link management handled by the group ID for reduced complexity, and device-level unicast link management maintained individually for reliability. This segmentation allows each layer to handle specific aspects of link management, combining the advantages of both approaches.
Solution Approach 2:
The group ID acts as an intermediary that coordinates communication within the group while individual device IDs maintain direct unicast link states. The group ID mediates group-level operations without eliminating device-level link management, allowing reliable direct communication while benefiting from simplified group coordination.
3Productivity
If common ID is used for multiple unicast links, then link management efficiency is improved, but identification precision worsens
Solution Approach 1:
The patent adds a dimensional hierarchy to link identification by introducing group IDs as a higher-level dimension and device IDs as a lower-level dimension. Instead of using single flat identifiers, the system uses hierarchical identifiers (group ID, device ID) that provide both efficient group-level management and precise device-level identification when needed.
Solution Approach 2:
The identification system implements nesting by placing device IDs within the context of group IDs. Each device in a group has its own unique device ID nested within the group's common ID, allowing the system to operate at the group level for efficiency while maintaining the ability to identify individual devices precisely when required.
