Hard Drive Latch Assembly with Rotatable Arm and Guide Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chassis designs for computer components, such as hard drives, often require complex and costly retention and extraction mechanisms for hard drive carriers or frames, limiting flexibility and increasing complexity, especially when trying to easily add or remove hard drives.
Innovation Solution
A chassis with a hard drive slot and a latch assembly that includes a rotatable arm, pin shaft, and spring member, which engages with positioning members on the hard drive for retention and extraction, allowing direct insertion and removal of hard drives without a carrier or frame, using guide rails for alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hard drive carrier or frame with complex retention mechanisms is used, then the hard drive can be retained securely in the chassis, but the device complexity and cost increase
Solution Approach 1:
The retention mechanism is segmented into modular components: guide rails with positioning members on the hard drive, and corresponding guide rails with positioning features in the chassis. This segmentation allows each component to perform a specific function (alignment, retention, extraction) independently, reducing overall complexity while maintaining security
Solution Approach 2:
The patent extracts the hard drive from its traditional carrier or frame, allowing the hard drive itself to integrate the necessary positioning and retention features directly. This eliminates the need for separate complex retention mechanisms on carriers, reducing device complexity while maintaining secure retention through the guide rail and latch assembly integration
2Reliability
If a hard drive carrier or frame with complex extraction mechanisms is used, then the hard drive can be retained securely, but the ease of operation for adding or removing drives decreases
Solution Approach 1:
The latch assembly incorporates a rotatable arm that can dynamically transition between locked and unlocked positions. This dynamic mechanism allows the hard drive to be securely retained during normal operation but easily extracted when needed, simply by rotating the arm to release the latch. The spring member provides automatic engagement, making the operation intuitive and efficient
Solution Approach 2:
The spring member in the latch assembly provides self-service by automatically engaging with the positioning member on the hard drive when the drive is inserted. This automatic engagement eliminates the need for complex manual retention mechanisms, allowing secure retention without increasing operational complexity for the user
3Reliability
If a carrier or frame is used to house the hard drive, then the hard drive is protected and organized, but the quantity of components and cost increase
Solution Approach 1:
The patent merges the functions of the hard drive, carrier, and retention mechanism into an integrated system. The hard drive includes integrated positioning members that work with the chassis guide rails, eliminating the need for separate carriers and complex retention mechanisms. This merging reduces the quantity of components while maintaining protection and organization through the unified design
Solution Approach 2:
The guide rails and positioning members are designed with universality, serving multiple functions: guiding the hard drive during insertion, positioning the drive accurately, enabling retention through the latch assembly, and facilitating easy extraction. This multi-functionality reduces the need for separate specialized components, decreasing component quantity while maintaining protection and organization
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the retention and extraction process, reducing complexity and cost, while allowing for easy replacement of hard drives and accommodating various types of drives, including solid state drives, by using a latch assembly that shifts between rest and engaged positions with a torsion or compression spring mechanism.
Implementation Method 1
a spring member to engage with the hard drive slot and may shift from a rest position to an engaged position based on the position of the rotatable arm
Implementation Method 2
using a latch assembly that shifts between rest and engaged positions with a torsion or compression spring mechanism
Implementation Method 3
using a latch assembly that shifts between rest and engaged positions with a torsion or compression spring mechanism

AI summary
Examples include a system comprising chassis and hard drive. In some examples, the hard drive has a set of positioning members and the chassis includes a hard drive slot having a guide rail unit to guide the hard drive into the hard drive slot via a positioning member of the set of positioning members on the hard drive. The chassis also includes a latch assembly connected to the hard drive slot to retain and extract the hard drive.
