Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If voltage and clock frequency are adjusted to match host device performance, then power consumption is reduced, but system complexity increases due to additional power management controller and clock management module
Solution Approach 1:
The system divides power management functions into separate modules: a power management controller that determines voltage and clock frequency settings, and a clock management module that executes the frequency adjustments. This segmentation allows independent optimization of each component while achieving overall power reduction.
Solution Approach 2:
The power management controller continuously monitors host device performance and dynamically adjusts voltage and clock frequency settings based on actual usage conditions. This feedback mechanism ensures power consumption is optimized without manually configuring system parameters.
2Loss of energy
If dynamic voltage and clock frequency adjustment is implemented, then energy efficiency improves, but control complexity increases
Solution Approach 1:
The system performs self-adjustment of voltage and clock frequency through the power management controller that automatically monitors host performance and modifies power settings without external intervention. This eliminates the need for manual configuration and reduces operational complexity.
Solution Approach 2:
The system dynamically changes operational parameters (voltage and clock frequency) based on host device performance requirements. The power management controller adjusts these parameters in real-time to optimize energy efficiency while maintaining adequate performance levels.
3Use of energy by moving object
If power supply is optimized based on operation conditions, then power consumption decreases, but measurement and detection difficulty increases
Solution Approach 1:
The power management controller acts as an intermediary between the host device and the power supply system. It monitors host performance metrics and translates these into appropriate voltage and clock frequency settings, simplifying the detection and measurement of operation conditions.

AI summary
A memory system includes non-volatile memory. The memory system includes a controller that controls data transfer between a host and the non-volatile memory, and a power supply unit that supplies a voltage to the controller. Further, the controller includes a power supply control unit that determines the voltage supplied to a module in the controller on the basis of an operation condition determined with the host. The power supply unit adjusts the voltage supplied to the module in accordance with a command from the power supply control unit.
