Solution Overview

Problem

Existing computer systems face challenges in safely removing modules without damaging connected cables, as traditional quick release mechanisms do not prevent ejection when cables are still plugged in, risking cable damage during module removal.

Innovation Solution

A cable detection mechanism, such as a cable interference tab, integrated into the ejection mechanism that prevents module disengagement when cables are plugged in, ensuring cables are disconnected before module removal by blocking the eject button.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a quick release mechanism is used to allow easy module removal, then ease of operation is improved, but the risk of cable damage during module removal increases

Engineering Contradiction:

Improvemodule removalVSAvoidcable damage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cable detection mechanism performs a preliminary check before allowing module ejection. The eject button is designed to detect cable presence in advance and prevent the ejection action from occurring if cables are connected, thereby avoiding cable damage while maintaining quick release functionality for safe scenarios

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The eject button acts as an intermediary mechanism between the user's ejection action and the actual module removal. It mediates by detecting cable presence and either allowing or blocking the ejection force from being transmitted to the module, thus preventing harmful cable damage while enabling quick removal when safe

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An eject mechanism for a module includes a module casing; a module engaged in the module casing; the module including a cable port; and an eject button for allowing disengagement of the module from the module casing. The eject button prevents the module from disengagement when a cable is plugged into the cable port. A method of ejecting a module from a module casing includes disengaging the module from the module casing upon the pressing of an eject button, and preventing the module from disengagement when a cable is plugged into a cable port of the module.
