Hinged Cup Slotfiller for Reliable Computer Rack Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer-rack components with open slots lead to re-circulation of hot air, deteriorating cooling efficiency and potentially causing component failure, and current solutions like metal brackets are cumbersome and risky to install.
Innovation Solution
A slotfiller with two cup elements connected by a hinge, designed for easy insertion and snap-fit closure of open slots, using ergonomic chamfered surfaces and elastic hinges to secure fit without direct pressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal brackets are used to close off unused PCI slots, then the slots are securely closed, but the installation process becomes highly time-consuming and finicky
Solution Approach 1:
The slotfiller is divided into multiple cup elements (at least two) that can be independently pressed towards each other, allowing the closure mechanism to be segmented into manageable parts that are easier to install than a single rigid metal bracket
Solution Approach 2:
The slotfiller transitions from an open state (cup elements apart) to a closed state (cup elements pressed together), enabling dynamic installation without requiring tools or complex assembly steps like traditional metal brackets
2Reliability
If metal brackets are used to close off unused PCI slots, then the slots are securely closed, but the risk of damaging components increases due to sharp metal composition
Solution Approach 1:
The material parameter is changed from sharp metal to rounded plastic cup elements, eliminating the harmful sharp edges while maintaining the closure function through the elastic deformation and pressing mechanism of the cups
Solution Approach 2:
The cup elements function as flexible shells that can deform during insertion and pressing, allowing the slotfiller to adapt to the slot opening without risking damage to surrounding components, unlike rigid metal brackets
3Ease of operation
If the slotfiller is designed to be easily inserted by pressing cup elements, then installation becomes quick and simple, but the mechanism requires additional components (hinge, multiple cups)
Solution Approach 1:
Multiple cup elements are merged with a hinge mechanism to create a single integrated slotfiller component that functions as a complete closure system, combining what could be separate parts into one installable unit

AI summary
The present disclosure concerns a slotfiller (1) for closing a slot (21) in a computer-rack-insertable component (20), wherein the slotfiller (1) comprises at least two finger-grippable cup elements (2), and a hinge (3) connecting the cup elements (2). Therein, the slotfiller (1) is configured to be insertable into the slot (21) by pressing of the cup elements (2) towards each other and is configured to at least partially cover an open surface area of the slot (21) by releasing of the cup elements (2) in the inserted state. The present disclosure also concerns a computer-rack-insertable component (20) and a computer rack (100), each comprising at least one slotfiller (1).
