Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If cooling fan speed is controlled based on temperature alone, then cooling effect is ensured, but power consumption increases due to unnecessarily high fan speeds
Solution Approach 1:
The patent changes the control parameters from temperature-only to a composite parameter that includes temperature, hardware configuration, and facility environment. This allows the system to determine optimal fan speeds that balance cooling effectiveness with power consumption reduction.
Solution Approach 2:
The patent implements dynamic fan speed adjustment based on real-time monitoring of temperature, hardware configuration, and facility environment. The control algorithm continuously adapts fan speeds to current operating conditions, ensuring optimal performance while minimizing energy consumption.
2Loss of energy
If cooling fan speed is reduced to save power, then energy consumption decreases, but cooling performance may deteriorate
Solution Approach 1:
The patent employs feedback control where the system continuously monitors temperature, hardware configuration, and facility environment, then adjusts fan speeds accordingly. This closed-loop control ensures that power consumption is minimized while maintaining adequate cooling performance through real-time adjustments.
Solution Approach 2:
The control algorithm dynamically changes operating parameters (fan speed) based on the relationship between temperature conditions, hardware configuration, and facility environment. This allows optimization of the balance between power consumption and cooling performance.
3Adaptability or versatility
If generic cooling control algorithm is used, then system compatibility is maintained, but optimization for specific hardware configurations is lost
Solution Approach 1:
The patent applies local quality by tailoring the cooling control to specific hardware configurations and facility environments. Instead of a uniform approach, the system adapts control parameters to match the specific characteristics of each installation, achieving both compatibility and optimization.
Solution Approach 2:
The control algorithm dynamically adjusts parameters based on detected hardware configuration and facility environment characteristics. This allows the system to maintain broad compatibility while achieving specific optimization for each installation scenario.

AI summary
Power consumption of a cooling fan of an information processing device is reduced. A processor reduces a speed of the cooling fan provided in the information processing device, and controls the cooling fan at a first speed when there is no problem with the operation of the information processing device, the first speed being obtained by reducing the speed of the cooling fan. An interface transmits first information indicating the first speed to a management device. The processor receives second information indicating a second speed from the management device that associates the first speed with identification information identifying the information processing device and stores therein the first information indicating the first speed and the identification information, and controls the speed of the cooling fan according to the second speed when the second speed is lower than the first speed.
