Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collaboration cell is determined based on initial transmission delay and bandwidth requirements, then the collaboration function can be established, but if transmission conditions change the collaboration function gain is reduced or the function fails
Solution Approach 1:
The patent implements dynamic re-evaluation of transmission scenarios by periodically acquiring updated transmission delays and bandwidths of collaboration cells. The network device dynamically adjusts the selection of collaboration cells based on current transmission conditions, transforming the static cell determination into a dynamic adaptation process that responds to changing network states.
Solution Approach 2:
The patent establishes a feedback mechanism where the network device continuously monitors transmission delays and bandwidths of collaboration cells, compares them against the preset collaboration function requirements, and triggers re-selection when deviations are detected. This closed-loop feedback ensures the collaboration function maintains optimal performance despite transmission condition variations.
2Productivity
If transmission delay or bandwidth of a collaboration cell changes after determination, then the cell can continue to be used for collaboration, but the collaboration function gain is reduced
Solution Approach 1:
The patent performs preliminary acquisition of transmission delays and bandwidths for candidate collaboration cells before final selection. By pre-evaluating transmission scenarios and identifying cells that meet requirements in advance, the system avoids complex real-time adjustments when conditions change, simplifying the overall selection process while maintaining high collaboration function gain.
Solution Approach 2:
The patent monitors changes in transmission parameters (delay and bandwidth) of collaboration cells and triggers re-selection when parameter deviations exceed thresholds. This parameter-based adaptation mechanism balances productivity maintenance with complexity control by only initiating re-selection when necessary, rather than continuously adjusting the collaboration configuration.
3Adaptability or versatility
If a fixed collaboration cell is selected, then the system configuration is simple, but the system cannot adapt to changing transmission conditions
Solution Approach 1:
The patent segments the collaboration cell selection process into distinct phases: initial transmission scenario acquisition, transmission condition monitoring, requirement comparison, and conditional re-selection. This segmentation allows the system to maintain simple configuration during stable periods while enabling complex adaptation only when transmission conditions change, balancing adaptability with complexity management.
