Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple WiMAX connection-based paths are established for data transmission, then transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent segments the data transmission process by dividing data frames into multiple segments that can be transmitted through different WiMAX connection-based paths simultaneously. This segmentation allows the system to achieve diversification in transmission routes, improving reliability against interference while maintaining manageable complexity through structured data division and path assignment mechanisms.
2Productivity
If data transmission is adjusted based on quality condition of multiple paths, then transmission efficiency is improved, but control complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the quality conditions of multiple transmission paths are continuously monitored and evaluated. Based on this feedback, the system dynamically adjusts data frame transmission strategies, selecting optimal paths or combinations of paths for different data segments. This feedback-driven approach improves transmission efficiency by adapting to changing channel conditions while maintaining controlled complexity through systematic quality assessment and policy-based adjustment rules.
3Object-affected harmful factors
If multiple paths are used for data transmission, then resistance to interference is improved, but system configuration complexity increases
Solution Approach 1:
The patent utilizes parameter changes in WiMAX connection configurations to establish multiple transmission paths with different characteristics. By varying parameters such as connection identifiers, frequency channels, or routing parameters, the system creates diverse transmission paths that offer different levels of interference resistance. This parameter-based approach enables the system to achieve interference diversity while maintaining configuration manageability through standardized parameter adjustment procedures.
