Solution Overview

Problem

The existing methods for securing expansion cards in servers require the use of tools to install and remove them, which is inconvenient for users.

Innovation Solution

A fixing mechanism that includes a housing with sliding members and a fixing member, allowing the expansion card to be locked or unlocked without tools by sliding the member relative to the housing, forming a limiting fit with the card's edge to secure or release it.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to fasten the expansion card, then the expansion card is securely fixed in the server, but tools are required to install and remove the expansion card

Engineering Contradiction:

Improvesecure fixationVSAvoidinstallation and removal convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fixing mechanism allows the expansion card to be installed and removed by the user without requiring external tools. The sliding member can be manually moved along the guide groove to engage or disengage from the limiting portion of the expansion card, enabling self-service installation and removal operations.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the traditional screw-fastening mechanical system with a sliding member-based locking mechanism. The sliding member moves along a guide groove and engages with a limiting portion on the expansion card, substituting the need for screws and screwdrivers with a simpler manual sliding operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If screws are used to fasten the expansion card, then the expansion card remains securely in place, but the operation becomes complex and time-consuming

Engineering Contradiction:

Improvesecure fixationVSAvoidinstallation and removal time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The fixing mechanism enables users to install and remove expansion cards independently without requiring assistance or specialized tools. The sliding member can be manually operated to lock or unlock the expansion card, significantly reducing the time and complexity compared to traditional screw fastening methods.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The fixing mechanism transitions from a static screwed connection to a dynamic sliding connection. The sliding member can move freely along the guide groove during installation and removal operations, then locks into position during normal operation, providing both ease of operation and secure fixation.

Inventive Principle:

Principle #15Dynamics

AI summary

A fixing mechanism and a server, including a housing and a sliding member. The housing is used for accommodating an expansion card. The fixing member is slidably arranged on the housing and is used to form a limiting fit with a first limiting portion on the expansion card to lock the expansion card in the housing. The sliding member is slidably arranged on the housing, the sliding member can slide along the first direction and the reverse direction of the first direction, the first direction is the direction in which the expansion card enters the housing.
