Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If communication parameters are calculated assuming constant frame size, then calculation simplicity is maintained, but parameter accuracy deteriorates
Solution Approach 1:
The patent applies dynamics by making the frame size variable rather than constant. The access point dynamically adjusts frame size based on the number of connected access points, and the calculation method dynamically selects different formulas based on whether the frame size varies. This resolves the contradiction by allowing accurate parameter calculation that adapts to changing communication conditions without requiring permanently complex calculation systems.
Solution Approach 2:
The patent changes the parameter of frame size from a fixed constant to a variable that depends on the number of connected access points. The calculation method accordingly changes parameters by selecting between different calculation formulas based on the actual frame size behavior, thereby maintaining accuracy while managing complexity through conditional parameter selection.
2Device complexity
If frame size variation is not considered, then calculation process remains simple, but communication reliability deteriorates
Solution Approach 1:
The patent introduces dynamics by enabling the calculation process to adapt to whether frame size varies. The system dynamically determines frame size based on connected access point count and selects appropriate calculation methods, ensuring reliable communication parameters are always calculated according to actual conditions rather than using a fixed simple approach.
Solution Approach 2:
The patent changes the frame size parameter from constant to variable, and consequently changes the calculation approach by providing different formulas for different scenarios. This ensures communication reliability by matching the calculation complexity to the actual communication conditions, preventing the use of inaccurate simplified calculations when frame size actually varies.
3Reliability
If accurate communication parameters are obtained by considering varying frame sizes, then communication reliability improves, but calculation complexity increases
Solution Approach 1:
The patent applies dynamics by making the calculation process adaptive rather than static. The system dynamically assesses whether frame size varies and selects the appropriate calculation formula accordingly. This resolves the contradiction by ensuring high reliability through accurate calculations only when necessary, while maintaining simplicity when frame size remains constant, thus balancing reliability and complexity.
Solution Approach 2:
The patent changes parameters by introducing conditional logic that selects between different calculation approaches based on frame size behavior. This ensures accurate communication parameters are obtained when frame size varies, while avoiding unnecessary calculation complexity when frame size is constant, thereby resolving the contradiction between reliability and complexity.
