Solution Overview

Problem

Existing foldable lifting desks have a single layer desktop, making it impossible to place both a computer and a keyboard simultaneously, and their unlocking structures occupy valuable desktop space, causing inconvenience.

Innovation Solution

A double-layer foldable lifting desk with a lever type unlocking structure, featuring an X-shaped lifting frame, a limiting shaft, and an unlocking mechanism that includes a rotating shaft base, unlocking lever, and a gas spring, allowing for separate sliding of the unlocking rotating rod and enhancing stability by using a lever principle to avoid occupying desktop space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a sliding plate unlocking structure is used that passes through the desktop board, then users can conveniently prod the sliding plate, but the desktop board area is occupied and usability is reduced

Engineering Contradiction:

Improveunlocking operation convenienceVSAvoiddesktop board available area

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The unlocking mechanism is extracted from the desktop board surface and relocated to the bottom frame. The sliding plate is replaced with a lever-type unlocking structure that operates from below the desktop board, allowing users to unlock the lifting frame without occupying any desktop board area while maintaining operational convenience.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of having the unlocking mechanism protrude upward from the desktop board surface, the invention inverts the structure by placing the unlocking mechanism on the bottom frame with the lever extending downward. This allows users to operate the unlocking mechanism from below the desktop board, effectively reversing the traditional arrangement and freeing up desktop board space.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If a single layer desktop design is used, then the structure is simple, but it is impossible to place both computer and keyboard simultaneously, reducing functionality

Engineering Contradiction:

Improvedesktop functionalityVSAvoiddesktop structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The desktop is segmented into two separate layers: an upper desktop board for placing items and a lower auxiliary desktop board for additional items. This segmentation allows users to place both computer and keyboard simultaneously on different layers, enhancing functionality while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-layer (2D) desktop design to a double-layer (3D) design by adding vertical dimension. The auxiliary desktop board is positioned below the main desktop board, creating a two-level structure that increases functional capacity without significantly increasing horizontal footprint.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

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

AI summary

The present invention discloses a double-layer foldable lifting desk with a lever-type unlocking structure and relates to the technical field of foldable lifting desks. The double-layer foldable lifting desk with the lever type unlocking structure includes a desktop board, wherein a lower side of the desktop board is connected to an X-shaped lifting frame, a lower end of which is connected to a bottom frame; a limiting shaft is arranged at one end of an upper side of the X-shaped lifting frame; one side of the bottom of the desktop board is connected through a bolt to a guide rail, which is slidingly connected to two ends of the limiting shaft; and an unlocking mechanism corresponding to the limiting shaft is arranged on a lower side of one end of the desktop board. The present invention has the following beneficial effects: the unlocking structure is arranged on the lower side of the desktop board so that the use space of the desktop side is not occupied; a lever principle is used to make an unlocking lever rotate, and the reasonable and simple structure is not liable to get stuck, thereby avoiding the inconvenience caused by the unlocking structure of the traditional lifting desk that occupies the area of the desktop board.
