Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed connection interface standard is used, then data transfer rate is improved, but device temperature and power consumption increase
Solution Approach 1:
The patent applies dynamics by making the connection interface standard adjustable rather than fixed. The memory control circuit dynamically switches between different connection interface standards (e.g., PCI Express Gen 1 to Gen 5) based on real-time device status, allowing the system to adapt the data transfer rate to actual operational needs, thereby reducing unnecessary heat generation while maintaining performance when required
2Speed
If high-speed connection interface standard is used, then data transfer rate is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the connection interface standard based on device status information, switching between high-speed and lower-speed modes depending on actual operational requirements. This prevents continuous operation at maximum speed when not needed, thereby reducing unnecessary power consumption while maintaining the capability for high-speed transfer when performance is required
Solution Approach 2:
The patent changes the operational parameter of connection interface standard based on device status. By monitoring whether the device is performing default operations and adjusting the interface standard accordingly, the system optimizes the balance between data transfer rate and power consumption, improving energy efficiency without sacrificing performance when needed
3Speed
If high-speed connection interface standard is used, then data transfer rate is improved, but performance per watt decreases
Solution Approach 1:
The memory control circuit dynamically adjusts the connection interface standard based on real-time device status monitoring. When default operations are detected, the system switches to appropriate interface standards that optimize the balance between data transfer rate and power consumption, thereby improving performance per watt while maintaining the capability for high-speed operation when necessary
4Loss of energy
If connection interface standard is adjusted, then energy conversion rate is improved, but device complexity increases
Solution Approach 1:
The memory control circuit autonomously monitors device status and automatically adjusts the connection interface standard without requiring external intervention. The system self-determines when to switch between different interface standards based on detected operations, simplifying the overall control architecture while achieving energy optimization
Solution Approach 2:
The system implements feedback control by continuously monitoring device status information and using this feedback to adjust the connection interface standard. This closed-loop approach allows the system to respond to changing operational conditions and optimize energy conversion rates while managing complexity through automated feedback-based decision making
