Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If physical delay is added to operations for power optimization, then power consumption is reduced, but human resource control complexity and error occurrence increase
Solution Approach 1:
The storage device automatically adjusts its own clock frequency based on real-time power consumption measurements without requiring external human control. The controller measures power consumption via current and voltage, compares it against thresholds, and autonomously adjusts the clock signal frequency to optimize power usage, eliminating the need for manual intervention and reducing control complexity.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where the controller continuously monitors real-time power consumption through ADC measurements of current and voltage, compares the measured power against predefined thresholds, and adjusts the clock frequency accordingly. This automated feedback loop resolves the contradiction by eliminating manual control while maintaining power optimization.
2Loss of energy
If power optimization is manually controlled, then power consumption can be optimized, but human resources and error occurrence increase
Solution Approach 1:
The storage device performs self-optimization of power consumption by automatically measuring its own power usage through integrated ADC modules and adjusting its internal clock frequency without external human intervention. This self-service approach increases automation level while maintaining effective power optimization.
Solution Approach 2:
The automated feedback mechanism continuously monitors power consumption and adjusts clock frequency in real-time, eliminating manual control requirements. This feedback loop implements high-level automation that maintains power optimization without human resource involvement.
3Loss of energy
If clock frequency is adjusted for power optimization, then power consumption decreases, but operational stability may be affected
Solution Approach 1:
The system dynamically adjusts the clock frequency based on real-time power consumption conditions rather than using a fixed frequency. The controller modifies the clock signal frequency in response to measured power usage, allowing the system to adapt between performance and power-saving modes while maintaining operational stability through condition-based adjustments.
Solution Approach 2:
The invention changes the operational parameter of clock frequency in response to power consumption thresholds. By adjusting the clock frequency parameter dynamically based on measured power usage, the system optimizes power consumption while maintaining stability through controlled parameter changes rather than arbitrary modifications.
