Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data storage systems face issues with undesirable acoustic energy transmission and backflow of air when air movers fail, leading to reduced airflow and performance degradation.
Innovation Solution
A cooling assembly with an air management system featuring circular components that move between open and closed positions to control airflow and reduce acoustic energy, using concentrically arranged circular components to manage air flow and block backflow by eliminating gaps when the air mover fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air movers are used to cool data storage systems, then cooling effectiveness is improved, but acoustic energy transmission increases
Solution Approach 1:
The air management assembly is divided into multiple circular components arranged concentrically, creating multiple gaps that collectively manage airflow while reducing acoustic energy transmission. Each circular component acts as an independent segment that can open or close to control air flow paths.
Solution Approach 2:
The circular components are designed to dynamically change position between open and closed states based on airflow conditions. This dynamic adjustment allows the system to optimize cooling effectiveness while minimizing acoustic energy transmission by closing gaps when air movers fail or during normal operation.
2Productivity
If air movers operate continuously, then cooling performance is maintained, but backflow occurs when air movers fail
Solution Approach 1:
The circular components are positioned and designed to automatically close and block backflow paths when airflow reverses or when air movers fail. This preliminary anti-action prevents backflow before it can compromise the cooling system or data storage devices, ensuring reliability without requiring continuous active control.
Solution Approach 2:
The air management assembly uses the airflow itself to trigger the closing of circular components when backflow occurs. The system self-regulates by allowing normal airflow during operation while automatically closing gaps to prevent backflow, eliminating the need for external sensors or control mechanisms.
3Productivity
If gaps between circular components are maintained for airflow, then cooling efficiency is improved, but backflow paths are created when air movers fail
Solution Approach 1:
The gaps between circular components are dynamically adjustable rather than fixed. During normal operation, gaps remain open to maintain cooling efficiency. When air movers fail or backflow occurs, the circular components close to eliminate gaps and block backflow paths, resolving the contradiction between maintaining open gaps for cooling and closing them to prevent backflow.
Applied Scientific Principles

Function Achieved in This Case
The solution effectively reduces acoustic energy transmission and prevents backflow, maintaining airflow and performance even when air movers malfunction, by using concentrically arranged circular components that adjust positions based on air flow direction.

AI summary
A cooling assembly includes an air mover assembly including an inlet. The cooling assembly further includes an air management assembly that is coupled to the air mover assembly and that includes circular components arranged concentrically with respect to each other such that the circular components can move between an open position and a closed position. In the open position, the circular components have gaps between each other. In the closed position, the circular components reduce or eliminate the gaps between each other.
