Expansion Card Receiver With Retractable Handle For Dense Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing sophistication of computing devices has made it challenging to physically access and manipulate hardware components, such as expansion cards, due to increased packing density, which can lead to damage during removal or insertion, especially in densely packed chassis environments.
Innovation Solution
An expansion card receiver that reversibly transitions between two states, with a hidden handle in the first state for compact packing and an exposed handle in the second state for easy manipulation, allowing for safe insertion and removal without damaging the components or the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If components are densely packed to increase packing density, then space utilization is improved, but accessibility and ease of manipulation of hardware components deteriorates
Solution Approach 1:
The expansion card receiver is divided into distinct functional segments: a receiving portion for the expansion card, a management portion for user interaction, and a handle for manipulation. This segmentation allows the receiver to maintain compact integration while providing dedicated accessible control elements.
Solution Approach 2:
The handle acts as an intermediary element between the user and the expansion card receiver. It provides a convenient grip point that extends accessibility without requiring direct manipulation of the densely packed receiver structure, allowing users to safely interact with the component.
2Stability of the object's composition
If expansion card receiver is locked to chassis for secure mounting, then stability is improved, but ease of removal and insertion deteriorates
Solution Approach 1:
The expansion card receiver transitions from a static locked state to a dynamic removable state through the management portion mechanism. The receiver can be securely locked during operation and easily removed when needed, providing adaptability between stability and ease of operation requirements.
Solution Approach 2:
The management portion incorporates a self-contained locking and unlocking mechanism that allows the expansion card receiver to be securely mounted during operation and easily removed when needed, without requiring external tools or complex procedures.
3Ease of operation
If handle is exposed for easy manipulation, then ease of operation is improved, but device complexity and space occupation deteriorates
Solution Approach 1:
The handle is nested within the management portion of the expansion card receiver, allowing it to be compact when not in use while providing easy access when needed. This nesting approach maintains structural efficiency while ensuring operational convenience.

AI summary
A chassis for housing a computing device of an information handling system includes a receiving portion of an expansion card receiver that receives an expansion card and operably connects the expansion card to another component of the computing device while the expansion card is received by the receiving portion. The chassis further includes a management portion of the expansion card receiver that receives a force from a user and, in response to receiving the force: transitions the management portion from a first state to a second state. In the first state, a handle, that enables the expansion card to be removed from the chassis is disposed inside of the management portion and the expansion card receiver is locked to the chassis. In the second state, the handle is disposed outside of the management portion and the expansion card receiver is unlocked from the chassis.
