Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the amount of cooling airflow is increased to improve heat dissipation of the storage array, then the heat dissipation performance is improved, but the backflow of cooling airflow becomes stronger which reduces the effectiveness of heat dissipation
Solution Approach 1:
The flapper components are positioned to preemptively block the backflow path of cooling airflow before it can re-enter the storage array. By placing the flappers at strategic locations, the design prevents the harmful backflow effect from occurring, thereby maintaining effective heat dissipation even at high airflow rates.
Solution Approach 2:
The flapper components act as intermediary elements between the cooling airflow source and the storage array. These flappers control and regulate the airflow direction, allowing cool air to reach the storage array for heat dissipation while preventing the backflow of warmed air from re-entering the array.
2Temperature
If flapper components are used to block backflow of cooling airflow, then the heat dissipation effectiveness is improved, but the device complexity increases due to additional components
Solution Approach 1:
The flapper components are designed to be rotatable rather than fixed, allowing them to dynamically adjust their position based on airflow conditions. This dynamic design enables the flappers to automatically open or close as needed, providing adaptive backflow prevention without requiring complex control systems or multiple static components.
Solution Approach 2:
The flapper components are positioned and designed to automatically respond to airflow patterns without external control. The structure of the flappers themselves enables them to self-adjust their position based on the pressure and direction of the cooling airflow, eliminating the need for additional actuators, sensors, or control mechanisms.
