Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission rate control is not performed, then wireless communication simplicity is maintained, but communication quality degrades and transmission efficiency decreases
Solution Approach 1:
The patent implements feedback mechanisms where the receiving apparatus measures radio propagation conditions and communicates this information back to the transmitting apparatus. The transmitting apparatus then adjusts transmission parameters based on this feedback, creating a closed-loop control system that maintains communication quality without requiring complex centralized control.
Solution Approach 2:
Each wireless communication apparatus autonomously controls its own transmission rate based on locally measured radio propagation conditions and received capability information. This self-service approach eliminates the need for complex external control mechanisms while maintaining optimal transmission performance.
2Adaptability or versatility
If multiple information processing apparatuses transmit data simultaneously, then data exchange capability increases, but interference increases and communication stability decreases
Solution Approach 1:
The patent enables each transmitting apparatus to independently adjust its transmission characteristics based on local radio propagation conditions and the specific capabilities of the receiving apparatus. This localized adaptation allows multiple apparatuses to coexist in the same wireless environment without causing mutual interference, as each transmitter optimizes its parameters for its specific communication context.
3Productivity
If transmission rate is increased to improve efficiency, then productivity increases, but communication quality degrades under poor radio conditions
Solution Approach 1:
The patent implements dynamic transmission rate control where the transmitting apparatus continuously adjusts the data transmission rate based on real-time radio propagation measurements and feedback from the receiving apparatus. This dynamic adjustment allows the system to maximize transmission efficiency when conditions are good while automatically reducing the rate when conditions deteriorate, maintaining communication quality across varying conditions.
4Productivity
If frequency channel switching is implemented to improve transmission rate, then productivity increases, but system complexity and measurement requirements increase
Solution Approach 1:
The patent uses feedback mechanisms where the receiving apparatus measures radio propagation conditions on different frequency channels and communicates this information to the transmitting apparatus. Based on this feedback, the transmitting apparatus automatically selects the optimal frequency channel, eliminating the need for complex centralized frequency management while achieving optimal transmission rates.
