Hot Plug Drive Carrier Push-to-Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems lack an efficient mechanism for securely inserting and removing drive carriers, such as M.2 devices, without damaging the connectors or causing misalignment issues during the process.
Innovation Solution
A hot plug drive carrier with a push-to-release mechanism that utilizes a latch wire and track segments with a spring bias, allowing the handle to transition between positions within the track, ensuring proper alignment and secure connection, and enabling easy ejection by transitioning the latch wire along the track's channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure latch mechanism is implemented to prevent misalignment and damage, then connection reliability is improved, but device complexity increases due to additional components like latch wire and track segments
Solution Approach 1:
The track is divided into multiple segments (first segment, second segment, third segment) that can move independently relative to each other. This segmentation allows the latch mechanism to control handle position through staged movement of segments rather than a single complex locking component, resolving the contradiction by distributing complexity across simpler modular elements while maintaining secure connection.
Solution Approach 2:
The latch mechanism uses a movable latch wire that transitions between different positions (first position, second position, third position) along the track channel, and segments that can dynamically change their relative positions. This dynamic behavior allows the system to provide secure locking when needed while enabling easy release, improving reliability without requiring an overly complex static structure.
2Ease of operation
If a push-to-release mechanism is added to enable easy removal, then ease of operation is improved, but device complexity increases due to the additional release mechanism
Solution Approach 1:
The push-to-release mechanism allows the handle itself to actuate the release function by simply pushing the handle along the track channel. The latch wire and segments are designed to respond automatically to this pushing motion, transitioning from a locked to an unlocked state without requiring separate release levers or complex actuating mechanisms. This self-service approach improves ease of operation while minimizing additional complexity.
3Manufacturing precision
If multiple track segments with alignment features are used to ensure proper positioning, then manufacturing precision is improved, but device complexity increases due to the segmented track structure
Solution Approach 1:
The track is segmented into multiple sections (first segment, second segment, third segment) with defined interfaces between them. Each segment can be manufactured and positioned independently with specific alignment features, allowing for precise positioning of the handle at different stages of insertion. This segmentation approach improves manufacturing precision by breaking down the complex alignment requirement into simpler, modular alignment tasks.

Function Achieved in This Case
The mechanism ensures secure insertion and easy removal of drive carriers, preventing misalignment and damage, while also triggering PCIe notifications for storage device removal, enhancing the operational efficiency and reliability of information handling systems.
Implementation Method 1
A spring is located between the first segment and the second segment and can exert a force on the second segment to bias the second segment in the misaligned position
Implementation Method 2
The latch wire moves along a channel in the track to enable a handle of the drive carrier to transition between multiple positions within the track

AI summary
A drive carrier includes a latch wire, and a track that includes first and second segments. The latch wire is configured to move along a channel in the track to enable a handle of the drive carrier to transition between multiple positions within the track. The first segment is to be placed in physical communication with the latch wire while the latch wire is at a first position and a second position within the track. The second segment is in physical communication with the first segment. The second segment is to transition between a misaligned position and an aligned position with respect to the first segment, and the latch wire is to transition from the second position to a third position within the track in response to the second segment being in the aligned position.
