Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooling fans are constantly rotated at maximum revolution speed to prevent computer failure, then reliability is improved, but power consumption increases
Solution Approach 1:
The cooling fan rotation speed is dynamically adjusted based on real-time temperature detection and predicted future temperature changes. The control unit varies the rotation speed between minimum and maximum ranges according to actual cooling needs, rather than maintaining constant maximum speed, thereby resolving the contradiction between reliability and power consumption.
Solution Approach 2:
The system performs preliminary temperature prediction using the prediction unit that calculates future temperature changes based on current temperature trends and environmental factors. This allows the control unit to proactively adjust fan speed before overheating occurs, maintaining reliability while avoiding excessive cooling and power waste.
2Use of energy by moving object
If cooling fans operate at variable speeds to reduce power consumption, then power consumption is reduced, but temperature control precision deteriorates
Solution Approach 1:
The system continuously monitors actual temperature changes and compares them with predicted temperature changes. The control unit uses this feedback to adjust the rotation speed command, ensuring that temperature control precision is maintained even when operating at variable speeds rather than constant maximum speed.
Solution Approach 2:
The prediction unit calculates future temperature changes in advance, allowing the control unit to pre-adjust fan speed to achieve target temperature changes. This preliminary action ensures precise temperature control while avoiding the need for constant maximum speed operation.
3Use of energy by moving object
If cooling equipment operates efficiently according to computer operational states, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The control unit performs multiple functions: it detects current temperature, predicts future temperature changes, determines target temperature changes, and controls fan rotation speed. By consolidating these functions into a single multi-functional control unit, the system achieves efficient power management without proportionally increasing overall system complexity.
Solution Approach 2:
The prediction unit performs preliminary calculations of future temperature changes based on current operational states. This allows the system to proactively optimize cooling efficiency without requiring complex real-time reaction mechanisms, thereby reducing power consumption while keeping the added complexity manageable.
