Solution Overview

Problem

Existing handles on device boxes in stacked electronic equipment chassis obstruct the assembly path and space, causing inconvenience during the pulling out and pushing in of device boxes, which is a common issue in electronic technology applications.

Innovation Solution

A dual-axis handle system with symmetrical racks and preset locking seats, allowing handles to rotate horizontally and vertically to disengage from locking seats, facilitating a two-stage pull-out mechanism that avoids mechanical interference with racks, enabling easy access to electronic components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a simple buckling structure is used for device boxes, then assembly and disassembly become easy, but the handle obstructs the assembly path and space for electronic products

Engineering Contradiction:
Improveease of pulling out device boxVSAvoidhandle structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The handle is divided into two independent rotation axes: a horizontal axis (first rotation axis) allowing 90-degree rotation to clear the assembly path, and a vertical axis (second rotation axis) allowing 180-degree rotation for full retraction. This segmentation enables the handle to perform multiple functions through sequential rotations without requiring a complex single-axis mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The handle transitions from a static structure to a dynamic one with two degrees of freedom. The horizontal rotation (first axis) dynamically clears the assembly path during insertion/removal operations, while the vertical rotation (second axis) dynamically retracts the handle to avoid obstructing electronic product assembly paths.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the handle is fixed in position, then the structure is simple, but it obstructs the assembly path and space for electronic products

Engineering Contradiction:
Improvehandle structure simplicityVSAvoidaccessibility to electronic components
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The handle is given movement in two dimensional directions: horizontal rotation (first axis) for initial path clearance and vertical rotation (second axis) for complete retraction. This multi-dimensional movement allows the handle to exit the assembly path space without requiring complex lateral displacement mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the handle rotates only horizontally, then the assembly path is cleared, but mechanical interference with racks still occurs during full retraction

Engineering Contradiction:
Improveassembly path clearanceVSAvoidmechanical interference with racks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The two-stage rotation mechanism ensures continuous useful action: the horizontal rotation (first axis) continuously clears the assembly path, followed by vertical rotation (second axis) that continuously retracts the handle to avoid rack interference during full device box extraction. This continuous multi-directional movement eliminates mechanical interference throughout the entire operation.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A dual-axis handle includes a base having an axial hole, a first pivot inserted into the axial hole and partially exposed from the base, a swing shaft having a shaft body pivotally connected to the outside of the first pivot and can be rotated 90 degrees in the horizontal direction and a second pivot extended from one side of the shaft body and arranged in a vertical direction to the first pivot, and a handle having a connecting body pivotally connected to the second pivot and a connecting groove provided on one side of the connecting body for receiving the partially exposed first pivot. The handle can be rotated 180 degrees vertically at the second pivot to avoid mechanical interference between the handle and the rack, and to facilitate the maintenance or replacement of electronic components inside the device box.
