Fan Control Device Dynamic Speed Threshold Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fan control devices struggle to appropriately control fans when the fan configuration pattern changes, as they cannot adjust the rotational speed settings in real-time, leading to potential loss of control over fan operations.
Innovation Solution
A fan control device with an acquisition unit to detect the number and type of fans, a storage unit for fan configuration patterns, and a specification unit to match the acquired configuration with stored patterns, allowing the setting of appropriate rotational speed thresholds, ensuring continued control even with changes in fan configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fan control device uses fixed rotational speed thresholds for controlling fans, then the control is simple and stable, but the device cannot adapt when fan configuration patterns change
Solution Approach 1:
The patent implements dynamic adjustment of rotational speed thresholds based on detected fan configuration patterns. The control device transitions from fixed thresholds to dynamically configurable thresholds that automatically adapt when fan configurations change, resolving the contradiction between simplicity and adaptability
Solution Approach 2:
The patent changes the parameter of rotational speed thresholds from fixed values to dynamically adjustable values based on fan configuration patterns. This allows the system to adapt to different fan types and configurations while maintaining simple operation through automatic parameter adjustment
2Reliability
If the fan control device individually controls multiple fans, then the control precision is improved, but the device cannot adjust control settings in real-time when configurations change
Solution Approach 1:
The patent incorporates feedback mechanisms where the control device detects fan configuration patterns and uses this information to automatically adjust control settings. This feedback loop enables real-time adaptation while maintaining reliable individual fan control
Solution Approach 2:
The patent stores multiple fan configuration patterns in advance, allowing the system to quickly match and adapt to configuration changes without real-time calculation. This preliminary preparation enables both reliable control and rapid adaptation

AI summary
Provided are a fan control device and a setting method capable of appropriately controlling fans even if a fan configuration pattern is modified. A fan control device is provided with: an acquiring unit for acquiring the quantity and types of fans connected to input/output ports; a storage unit for storing a plurality of fan configuration patterns indicating the quantity and types of the fans; a specifying unit for specifying a fan configuration pattern matching the quantity and types of fans acquired by the acquiring unit, from among the plurality of fan configuration patterns stored in the storage unit; and a setting unit for setting, in the fans connected to the input/output ports, a rotational speed threshold for use when the fans are rotated, associated with the fan configuration pattern specified by the specifying unit.
