Removable Cage Handle Locking for Guided Module Insertion

Solution Overview

Problem

Conventional electronic equipment with exchangeable modules faces inconvenience during installation and removal due to freely rotatable carry handles, which complicates the insertion process and ensures stable electrical connections.

Innovation Solution

A removable cage with a locking mechanism that fixes the carry handle relative to the cage body, allowing for convenient carrying and placement, and utilizes a lever mechanism for guided insertion and extraction, ensuring stable electrical connections through the engagement of electronic connectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the carry handle is made freely rotatable relative to the bracket, then it is convenient to carry the electronic module, but it causes inconvenience during insertion operation and complicates the insertion process

Engineering Contradiction:

Improveconvenience of carryingVSAvoidcomplexity of insertion process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The carry handle is designed to be rotatable relative to the bracket body through a pivot connection, allowing dynamic adjustment during carrying and insertion operations. The handle can rotate to different positions to accommodate user needs while maintaining a controlled range of motion through the pivot mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A pivot connection serves as an intermediary mechanism between the carry handle and the bracket body, enabling controlled rotation. This pivot joint acts as a mediator that allows the handle to move freely within a limited range while maintaining structural connection, resolving the conflict between carry convenience and insertion complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the carry handle is fixed relative to the cage body, then the insertion process is simplified, but it reduces convenience for carrying and placement

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The carry handle is designed to be rotatable relative to the bracket body through a pivot connection, allowing dynamic adjustment during carrying and insertion operations. The handle can rotate to different positions to accommodate user needs while maintaining a controlled range of motion through the pivot mechanism.

3Adaptability or versatility

If the carry handle is rotatable during insertion, then it is flexible for placement, but it prevents verification of complete installation without starting the electronic equipment

Engineering Contradiction:

Improveflexibility of placementVSAvoiddifficulty of verifying installation

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The carry handle incorporates a visual indicator mechanism that changes its appearance or position to indicate the installation state. When the handle is properly positioned and locked, it displays a specific visual state that allows users to verify complete installation without powering on the equipment.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The system provides visual feedback through the carry handle's position or indicator to confirm proper installation. This feedback mechanism allows users to detect whether the electronic module is fully installed and secured without needing to start the electronic equipment.

Inventive Principle:

Principle #23Feedback

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

The locking mechanism prevents arbitrary rotation of the carry handle, facilitating steady placement and ensuring stable electrical connections during insertion, while the lever mechanism simplifies the insertion and extraction processes, making operations more efficient and reliable.

Implementation Method 1

The carry handle pivots about a fulcrum, where the pushing part contacts the first constraint part, to move the cage body in the insertion direction further by the pivotally-connecting part

Methodology Applied

Scientific EffectLever: Lever

AI summary

An electronic apparatus includes an apparatus casing and a removable cage. The removable cage includes a cage body, a carry handle, and a locking mechanism disposed on the cage body. The carry handle includes a pivotally-connecting part, pivotally connected to the cage body, a handle body, and a pushing part. The handle body and the pushing part are oppositely connected to the pivotally-connecting part. The locking mechanism includes a latching part and an unlocking part. The latching part can be engaged into a lock slot of the pivotally-connecting part so that the carry handle is fixed relative to the cage body for carrying the cage body. The unlocking part can be driven to disengage the latching part from the lock slot. By the lever rule, the carry handle can move the cage body into the apparatus casing further or move the cage body reversely to depart from the apparatus casing.
