Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the memory device operates with high power consumption, then the operating performance is improved, but the energy efficiency deteriorates
Solution Approach 1:
The controller includes a feedback regulation circuit that monitors the actual power consumption of the memory device and dynamically adjusts the input voltage accordingly. When power consumption exceeds a threshold, the feedback circuit reduces the input voltage to improve energy efficiency while maintaining adequate operating performance. This closed-loop feedback mechanism resolves the contradiction by continuously optimizing the balance between power performance and energy efficiency.
Solution Approach 2:
The system dynamically changes the input voltage parameter based on real-time power consumption conditions. The feedback regulation circuit adjusts the voltage level according to the operating state, transforming the fixed voltage supply into a variable parameter that adapts to different power consumption scenarios, thereby improving energy efficiency without completely sacrificing operating performance.
2Use of energy by moving object
If the input voltage is reduced to decrease power consumption, then the energy efficiency is improved, but the operating reliability deteriorates
Solution Approach 1:
The feedback regulation circuit continuously monitors both power consumption and operating status, adjusting the input voltage to maintain reliability thresholds. When voltage reduction would compromise reliability, the feedback mechanism prevents further reduction, ensuring that energy efficiency improvements do not come at the cost of operating reliability.
Solution Approach 2:
The input voltage is transformed from a static parameter to a dynamic one that adapts in real-time to operating conditions. The system dynamically adjusts voltage levels within safe operating ranges, allowing for energy efficiency improvements while maintaining reliability through continuous adaptation rather than fixed voltage reduction.
