Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the memory clock frequency is increased to improve data processing speed, then the productivity is improved, but the wireless communication performance deteriorates due to frequency interference
Solution Approach 1:
The patent implements dynamic clock frequency adjustment by making the memory clock frequency changeable based on operational conditions. The controller monitors communication performance and adjusts the memory clock frequency in real-time, switching between different frequency states (e.g., first clock frequency and second clock frequency) to optimize both processing speed and communication reliability depending on the current operational context.
Solution Approach 2:
The patent changes the physical parameter of clock frequency to resolve the contradiction. By adjusting the memory clock frequency parameter based on detected communication performance degradation, the system can operate at higher frequencies for improved productivity when communication is stable, and switch to lower frequencies to prevent interference when communication performance deteriorates, thus dynamically balancing both requirements.
2Reliability
If the memory clock frequency is dynamically adjusted to prevent communication interference, then the wireless communication performance is maintained, but the device complexity increases
Solution Approach 1:
The patent employs a feedback mechanism where the controller continuously monitors wireless communication performance and uses this information to adjust the memory clock frequency. The communication performance detection unit provides feedback about interference levels, and the controller responds by adjusting the clock frequency accordingly, creating a closed-loop control system that automatically maintains communication reliability without requiring complex manual intervention.
Solution Approach 2:
The system performs self-adjustment of the memory clock frequency based on automatically detected communication conditions. The controller autonomously monitors for interference and adjusts frequencies without external control, making the complex frequency management transparent to the user and other system components, thus hiding the complexity while maintaining reliability.
