Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If more powerful fans are used to cool processors, then cooling performance is improved, but vibrations generated increase
Solution Approach 1:
The fan controller dynamically adjusts fan operation by determining critical vibration frequencies through monitoring component performance parameters and vibrations, then generates keep-out zones to avoid operating at these frequencies. This dynamic adaptation allows the system to maintain cooling performance while minimizing harmful vibrations in real-time
Solution Approach 2:
The system changes the operational parameters of the fan by identifying and avoiding specific frequency ranges (keep-out zones) that cause excessive vibrations. By monitoring performance parameters and vibration frequencies, the system adjusts fan operation to stay outside critical frequency ranges, thereby reducing vibrations while maintaining cooling effectiveness
2Quantity of substance
If smaller track sizes and tighter tolerances are used in disk drives to increase storage capacity, then storage capacity is improved, but sensitivity to vibrations increases
Solution Approach 1:
The system takes preliminary action by determining critical vibration frequencies and generating keep-out zones before operating the fan at frequencies that would harm the disk drive. By proactively identifying and avoiding frequency ranges that could cause performance degradation, the system protects the sensitive disk drive components from vibration-induced errors
Solution Approach 2:
The system continuously monitors component performance parameters and vibration frequencies, using this feedback to identify critical frequencies and adjust fan operation accordingly. This closed-loop feedback mechanism ensures that the disk drive operates in a stable environment by detecting and avoiding vibration conditions that would affect its performance

AI summary
Some embodiments of the present invention provide a system that controls a device that generates vibrations in a computer system. During operation, a critical vibration frequency is determined for the computer system. Next, a keep-out zone is generated based on the critical vibration frequency, wherein the keep-out zone specifies a range of frequencies to be avoided. Then, the device is controlled based on the keep-out zone to reduce vibrations generated by the device in the keep-out zone.
