Rotatable Stop Plate for Airflow Management in Dual Power Supply Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with dual power supply units, removing one unit disrupts airflow, leading to suboptimal heat dissipation for the remaining unit due to unbalanced airflow distribution.
Innovation Solution
The electronic device incorporates rotatable stop plates that pivot to block airflow when a power supply unit is removed, ensuring consistent airflow to the remaining units by covering the outlets in the receiving bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one power supply unit is removed from the chassis, then the device can be maintained or repaired, but the airflow distribution becomes unbalanced and heat dissipation deteriorates
Solution Approach 1:
A stop plate is introduced as an intermediary component to block the outlet corresponding to the removed power supply unit. This mediator redirects the airflow that would have gone to the empty space back toward the remaining power supply units, ensuring continuous effective cooling without requiring system shutdown or complex airflow control mechanisms
2Device complexity
If the outlet is left open after power supply unit removal, then the device structure remains simple, but airflow is lost and cooling efficiency decreases
Solution Approach 1:
The stop plate is designed to be rotatable rather than fixed, allowing it to pivot into position when needed to block the outlet. This dynamic configuration enables the system to adapt between open and closed states, maintaining cooling efficiency only when necessary while avoiding the need for a permanently complex structured outlet
3Temperature
If a fixed closure is used to block the outlet, then airflow is maintained, but the device complexity increases and maintenance difficulty rises
Solution Approach 1:
Instead of a fixed closure that would permanently increase structural complexity, a rotatable stop plate is used that can be easily positioned or removed. This allows the system to maintain simple geometry when the outlet is open while providing the option to block airflow dynamically, reducing both structural and maintenance complexity
Solution Approach 2:
The stop plate is pre-positioned or easily deployable to block the outlet before significant airflow disruption occurs. This preliminary action prevents the need for complex real-time airflow control systems while maintaining simple overall device structure

AI summary
An electronic device includes a receiving bracket and two electronic modules. The receiving bracket includes a partition plate to divide the receiving bracket into a first receiving space and a second receiving space. Each of the first receiving space and second receiving space includes an outlet located at an end of the receiving bracket. The partition plate defines a through slot. A stop plate is pivotably connected to an end of the through slot near the outlets. Two resilient tabs are formed on opposite sides of the stop plate, and respectively face the first receiving space and second receiving space. The electronic modules are received in the first receiving space and second receiving space, and deform the resilient tabs.
