Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a high-performance cooling fan is installed to actively discharge waste heat, then heat dissipation efficiency is improved, but vibration and noise are generated that reduce storage device efficiency and service life
Solution Approach 1:
An airflow guiding component with airflow guiding ducts is introduced as an intermediary between the fan module and storage modules. This component redirects airflow to pass through gaps between storage modules rather than directly impacting them, thereby maintaining heat dissipation effectiveness while reducing vibration and noise transmission to the storage devices.
2Temperature
If the fan module is positioned close to storage modules for effective cooling, then heat dissipation performance is improved, but structure-borne vibration transmission to storage modules increases
Solution Approach 1:
The airflow path is segmented into multiple channels through the airflow guiding ducts, which direct cooling air through gaps between storage modules. This segmentation allows the fan to remain positioned for effective cooling while the divided airflow paths prevent direct structure-borne vibration transmission to individual storage modules.
3Ease of manufacture
If a simple fan mounting structure is used to reduce manufacturing cost, then manufacturing cost is reduced, but vibration isolation and noise reduction capabilities are insufficient
Solution Approach 1:
The airflow guiding component serves as both a functional airflow director and a passive vibration isolation intermediary. By positioning this component between the fan module and storage modules, it provides vibration and noise reduction capabilities without requiring complex active vibration control systems, maintaining cost-effectiveness while improving performance.
