Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of paths is increased to achieve desired network quality and reliability, then network reliability is improved, but network load increases
Solution Approach 1:
The patent implements dynamic path selection by continuously measuring network states (delay, loss rate, available bandwidth) and calculating evaluation values for each path. The system adaptively selects the optimal number of paths based on current network conditions, transitioning from a static all-paths approach to a dynamic selective approach that maintains reliability while reducing load.
Solution Approach 2:
The patent changes the parameter of path selection from using all available paths to using a selected subset based on evaluation values. By introducing evaluation criteria (combining delay, loss rate, and bandwidth parameters) and selecting paths based on these evaluations, the system reduces the quantity of transmitted frames while maintaining the reliability function.
2Reliability
If the number of paths is increased to achieve desired network quality, then network reliability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the number of active transmission paths based on real-time network state measurements and evaluation values. This dynamic adjustment reduces the number of simultaneously active paths compared to using all paths, thereby reducing power consumption while maintaining the required reliability level through selective path usage.
Solution Approach 2:
The patent converts the potential harm of reduced path diversity into a benefit by using intelligent evaluation and selection. Instead of blindly using all paths (which consumes excessive power), the system evaluates each path's quality and selects only the necessary number of high-quality paths, turning the limitation of reduced path count into an efficiency advantage.
3Reliability
If all paths are used for frame transmission, then network reliability is improved, but transmission efficiency decreases
Solution Approach 1:
The patent changes the transmission approach from uniform use of all paths to selective use of evaluated paths. By introducing evaluation parameters (delay, loss rate, bandwidth) and using these to select the optimal subset of paths, the system improves transmission efficiency by avoiding low-quality paths while maintaining reliability through duplication on selected paths.
Solution Approach 2:
The system dynamically selects which paths to use for transmission based on real-time evaluation of network states. This dynamic selection process allows the system to adapt to changing network conditions, consistently choosing the most efficient paths for transmission while maintaining the reliability function through selective duplication.
