Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data traffic capacity is increased to meet all functional unit requirements, then communication reliability is improved, but resource waste occurs due to allocating maximum capacity to all units simultaneously
Solution Approach 1:
The patent dynamically changes the capacity allocation parameters for different functional units based on predicted future communication requirements. Instead of allocating fixed maximum capacity to all units, the system adjusts capacity parameters (data rate, bandwidth) according to the specific needs of each unit at different time points, thereby improving communication reliability when needed while avoiding resource waste when full capacity is not required.
Solution Approach 2:
The system implements dynamic capacity allocation where the available capacity for each functional unit changes over time based on predictions of future communication requirements. The determination device continuously updates capacity assignments according to predicted traffic patterns, ensuring that capacity is available when needed while being released when not required, thus balancing reliability and resource efficiency.
2Device complexity
If capacity is allocated based on current requirements only, then resource allocation simplicity is maintained, but future overload situations occur when communication requirements change
Solution Approach 1:
The patent applies preliminary action by predicting future communication requirements of functional units before they actually occur. The determination device uses prediction algorithms to anticipate future traffic demands and pre-allocates capacity accordingly, preventing future overload situations. This allows the system to maintain simple current allocation while ensuring future stability through advance planning.
Solution Approach 2:
The system implements feedback mechanisms where actual communication requirements are continuously monitored and compared with predicted requirements. This feedback loop allows the determination device to adjust capacity allocations dynamically, ensuring that future overload situations are prevented while maintaining allocation simplicity through automated adjustment based on real-world performance data.
3Reliability
If maximum capacity is allocated to high-priority functions, then quality of service for important functions is improved, but low-priority applications suffer from starvation
Solution Approach 1:
The patent applies local quality by allocating different capacity levels to different functional units based on their specific priority and requirements. High-priority functions receive sufficient capacity to maintain quality of service, while low-priority functions receive adequate residual capacity to prevent complete starvation. This localized quality differentiation ensures that each function receives appropriate resources according to its specific needs rather than applying a uniform allocation strategy.
Solution Approach 2:
The system uses partial action by allocating capacity in proportions that satisfy minimum requirements for all functional units while providing excess capacity to high-priority functions when available. This ensures that low-priority applications receive partial service (preventing starvation) while high-priority functions can utilize excess capacity when needed, balancing quality of service with overall application utilization.
