Solution Overview

Problem

Conventional server lock mechanisms are difficult to operate and occupy significant space, hindering maintenance and design efficiency.

Innovation Solution

A lock mechanism comprising a frame, lock member, elastic member, operating member, and unlock member, which allows for easy operation and minimal space usage by engaging and disengaging components through elastic force and rotational mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional lock mechanism is used to prevent server sliding, then the server can be securely locked in the rack, but the lock mechanism occupies much space and is not easy to operate

Engineering Contradiction:

Improvelocking reliabilityVSAvoidoperation ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The lock mechanism is divided into independent functional modules: a lock member for engagement, an operating member for user input, and an elastic member for actuation. This segmentation allows each component to be optimized for its specific function while maintaining overall compactness and ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The operating member and unlock member are nested within the frame structure, with the unlock member positioned inside the operating member. This nesting arrangement reduces the overall space occupied by the lock mechanism while maintaining all necessary functional elements.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If a conventional lock mechanism is used to prevent server sliding, then the server can be securely locked in the rack, but the lock mechanism occupies much space

Engineering Contradiction:

Improvelocking reliabilityVSAvoidlock mechanism volume

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The lock member is designed to be movable relative to the frame, transitioning between locked and unlocked positions. This dynamic design allows the lock mechanism to achieve reliable locking while occupying minimal space when not in use, as the movable components can be retracted or positioned compactly.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the unlock member is pressed to release the lock, then the lock member moves inward disengaging from the housing, but the mechanism requires precise engagement and disengagement

Engineering Contradiction:

Improveunlocking easeVSAvoidengagement precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The elastic member automatically returns the lock member to its engaged position with the housing after the unlock member is released. This self-service mechanism ensures precise engagement without requiring additional actuation or complex control systems, simplifying both operation and manufacturing tolerances.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The elastic member acts as an intermediary between the unlock member and the lock member, transmitting the release action and providing the return force. This intermediary component facilitates easy operation while maintaining precise engagement through its elastic properties, which naturally provide smooth, controlled movement.

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates easy installation and removal of server chassis from racks while minimizing space occupation, enhancing maintenance and design flexibility.

Implementation Method 1

The first elastic member is connected to the lock member. When the unlock member is pressed, the fourth engaging portion disengages from the second engaging portion and the first elastic member drives the lock member to move toward an inside of the frame

AI summary

A device with lock function includes a housing, a casing and a lock mechanism. The housing has a first engaging portion. The lock mechanism includes a frame, a lock member, a first elastic member, an operating member and an unlock member. The frame has a second engaging portion. The lock member has a third engaging portion engaging with the first engaging portion to lock the casing in the housing. The unlock member has a fourth engaging portion engaging with the second engaging portion to restrain the operating member. When the unlock member is pressed, the fourth engaging portion disengages from the second engaging portion and the first elastic member drives the lock member to move toward an inside of the frame, such that the third engaging portion disengages from the first engaging portion and the lock member drives the operating member to move toward an outside of the frame.
