Solution Overview

Problem

The existing technologies face challenges in efficiently and toollessly installing and removing solid-state drive (SSD) devices of varying sizes within computer systems, leading to issues with data transfer errors and increased installation time in data centers.

Innovation Solution

A latch assembly with a securing element and latch mechanism, including cylindrical elements and a magnetic connection, is designed to securely attach SSDs to a printed circuit board assembly (PCBA) without requiring tools, allowing for easy installation and removal of SSDs of different sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional cable sockets and mechanical fasteners are used to secure SSD devices, then the SSD can be firmly attached to the PCBA, but the installation and removal process requires tools and involves multiple steps that increase installation time and risk of damage

Engineering Contradiction:
ImproveEase of installation and removalVSAvoidInstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical fastening systems (screws, clips, cable sockets) with a magnetic field-based securing mechanism. The magnetic latch assembly uses magnetic attraction forces to hold the SSD device firmly to the PCBA, eliminating the need for manual tool operation while maintaining secure attachment. This substitution of mechanical systems with magnetic fields directly enables tool-less installation and removal, resolving the contradiction between ease of operation and installation time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic latch assembly enables the SSD device to be easily installed and removed by the user without requiring external tools or assistance. The magnetic attraction provides self-aligning and self-latching functionality, where the SSD naturally snaps into position and secures itself through magnetic force. This self-service characteristic allows rapid installation and removal operations, directly addressing both the ease of operation and time loss parameters.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If SSD devices of varying sizes are installed using fixed mechanical fasteners, then the attachment is secure, but the system cannot easily accommodate different SSD sizes and lengths

Engineering Contradiction:
ImproveAccommodation of various SSD sizesVSAvoidComplexity of latch assembly
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magnetic latch assembly is designed with universal functionality to accommodate multiple SSD form factors and sizes. The magnetic field generation and attraction mechanisms remain consistent across different configurations, allowing the same basic latch design to secure various SSD types. This universality enables the system to adapt to different SSD sizes without requiring complex reconfiguration, resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent employs adjustable magnetic field parameters and configurable latch positions to adapt to different SSD sizes and lengths. By varying the magnetic field strength, pole configurations, and latch placement, the system can optimize the magnetic securing mechanism for each specific SSD form factor. This parameter-based adaptability allows a single latch assembly design to handle multiple SSD types without increasing overall system complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If traditional cable connections are used for data transfer, then the SSD can be securely connected, but the cables and sockets become frail over time and introduce data transfer errors

Engineering Contradiction:
ImproveData transfer reliabilityVSAvoidService life of cable sockets
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent replaces traditional mechanical cable connections with a direct, tool-less magnetic latch securing mechanism that eliminates the need for separate cable assemblies. By integrating the data connection interface directly into the SSD device and using magnetic fields for mechanical securing, the system removes the cable and socket components that were prone to degradation. This substitution directly improves data transfer reliability by eliminating the frail cable connections while extending the service life of the stationary connection points.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
