Solution Overview

Problem

Existing quick release mechanisms for electronic assemblies in servers do not prevent accidental or unauthorized removal, including theft, as they can be easily operated by anyone.

Innovation Solution

A quick release mechanism featuring a fixed component with slide channels and engagement components, including a slidable portion and engagement portion, secured by magnetic attraction, which can only be disengaged by a specific disengagement component, preventing unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a simple quick release mechanism is used, then ease of operation is improved, but security against unauthorized removal deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a key component as an intermediary element that mediates between the user and the quick release mechanism. The key must be inserted into the quick release mechanism to activate the release, serving as a mediator that controls access. This resolves the contradiction by maintaining ease of operation for authorized users while preventing unauthorized removal through the key requirement.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the purely mechanical quick release mechanism with a system that incorporates magnetic attraction. The key contains a magnet that attracts to a corresponding magnet in the quick release mechanism, substituting traditional mechanical keyways with magnetic coupling. This maintains ease of operation through simple magnetic attraction while enhancing security by requiring the specific keyed magnetic connection.

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

2Reliability

If a keyed mechanism with magnetic attraction is used, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the physical parameter of magnetic attraction strength to achieve security without complex mechanisms. By using strong magnets in both the key and the quick release mechanism, the system creates a secure bonded state that is difficult to separate without the proper key. This resolves the contradiction by using magnetic field strength as the security parameter rather than mechanical complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite construction combining magnetic materials (magnets) with mechanical components (key, quick release mechanism). The key consists of a magnet embedded in a key body, and the quick release mechanism contains a magnet that attracts to the key's magnet. This composite approach achieves enhanced security through magnetic attraction while keeping the overall device structure relatively simple.

Inventive Principle:
Principle #40Composite materials

AI summary

A quick release mechanism includes a fixed component, at least one engagement component and a disengagement component. The fixed component has at least one slide channel and at least one first opening, and the at least one first opening communicates with one side of the at least one slide channel. The at least one engagement component includes a slidable portion and an engagement portion. The slidable portion is slidably located in the at least one slide channel, and the engagement portion is connected to the slidable portion and configured to penetrate through the at least one first opening. The disengagement component is removably disposed on the fixed component so as to move the engagement portion of the at least one engagement component to be located closer to or farther away from another side of the at least one slide channel.
