Remote Expansion Card Release Module for Shielded Slot Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing release devices for expansion cards in motherboards are often shielded by other expansion card assemblies, making it inconvenient to remove inner expansion cards without first removing outer cards, especially in systems requiring multiple simultaneous expansions.

Innovation Solution

A remote release module with a button, moving member, rotating shaft, and hooks that allow for the release of multiple expansion cards from a remote location, using a mechanism that rotates and retracts hooks to facilitate simultaneous card removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple expansion card assemblies are inserted into the motherboard simultaneously, then the system can support AI and high-end audio-visual products with multiple expansion cards, but the release device for the inner expansion card is shielded by outer expansion cards and cannot be pressed

Engineering Contradiction:

Improvesupport for multiple expansion cardsVSAvoidaccessibility of release device

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The release device is repositioned from the traditional front-facing location to a side-facing location on the motherboard. This dimensional change allows the release device to be accessible from the side rather than from the front, enabling users to access and press the release device for inner expansion cards without having to remove outer expansion cards first.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the innermost expansion card assembly needs to be removed, then all expansion card assemblies outside the innermost expansion card must be removed first, but this process is inconvenient for users

Engineering Contradiction:

Improveconvenience of card removalVSAvoidtime required for sequential removal

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The release device is divided into multiple independent release mechanisms, each corresponding to a specific expansion card slot. Each release device can be independently accessed and operated from the side of the motherboard, allowing users to remove expansion cards from any slot independently without needing to remove other expansion cards first.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the release device is positioned at the edge of the motherboard, then it is easily accessible, but it cannot be used when multiple expansion cards are installed as it gets shielded

Engineering Contradiction:

Improveaccessibility of release deviceVSAvoidusability with multiple expansion cards

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A remote release module includes a button, a moving member, a rotating shaft and at least one hook. The moving member is linked to the button and includes a first driving portion. The rotating shaft includes a second driving portion protruding from a peripheral side and at least a third driving portion, and the second driving portion is linked to the first driving portion. The at least one hook is disposed beside the at least one third driving portion. When the button is pressed, the moving member is driven, and the first driving portion drives the second driving portion to rotate the rotating shaft, and then the at least one third driving portion drives the at least one hook to retract.
