Adjustable-Angle Desk Structure for Space-Saving Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bulky and heavy OA office furniture, such as desks, are inconvenient to fold and store efficiently, as they require significant space when stacked.
Innovation Solution
An angle-adjustment unit is coupled to the desk, comprising left and right holding frames, restricting rods, a grip rod, inverted y-shaped desk legs, auxiliary connecting elements, and a front guarding panel, allowing the desk board to be rotated by a predetermined inclination angle and maintaining positional restriction, enabling the desk to be folded and stacked in a space-saving manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If bulky and heavy OA office furniture desks are stacked horizontally for storage, then the desks can be stored when not in use, but they occupy significant space and require the same direction alignment
Solution Approach 1:
The desk structure incorporates an angle-adjustment unit that enables the desk board to rotate dynamically between horizontal (working position) and inclined (storage position). This dynamic adjustment mechanism allows the desk to change its configuration from a fixed horizontal state to a folded inclined state, solving the contradiction by making the storage process adaptable and operationally simple despite the desk's bulky and heavy nature.
Solution Approach 2:
The angle-adjustment unit is divided into functional segments including restricting rods, holding frames, and auxiliary connecting elements. These segmented components work independently but cooperatively to achieve the overall folding function, making the complex operation of moving heavy desks more manageable and easier to execute.
2Volume of moving object
If the desk board is rotated by a predetermined inclination angle using the angle-adjustment unit, then the desk can be folded for space-efficient stacking, but the structure becomes more complex with multiple components
Solution Approach 1:
The angle-adjustment unit employs a nested structure where restricting rods are inserted into holding frames, and auxiliary connecting elements link various components. This nesting arrangement allows multiple functional elements to be compactly integrated, reducing the overall spatial footprint while maintaining the capability for predetermined inclination angle rotation, thus achieving space-efficient stacking without excessive structural complexity.
Solution Approach 2:
The auxiliary connecting elements serve as intermediaries that link the restricting rods, holding frames, and desk board. These intermediary components facilitate the transmission of force and motion between the various parts, enabling the complex rotation and positioning functions to be achieved through coordinated action of simpler individual elements, thereby managing structural complexity.
3Ease of operation
If restricting rods are made movable to allow forward and backward displacement, then the desk board can be easily positioned at predetermined angles, but the positioning precision may be compromised
Solution Approach 1:
The holding frames are pre-configured with specific geometric dimensions and attachment points that correspond to predetermined inclination angles. The restricting rods are designed to engage with these pre-established positions, ensuring that when the rods are moved forward or backward, they naturally settle into predetermined angular positions. This preliminary configuration ensures both ease of operation and positioning precision without requiring complex control mechanisms.

AI summary
A desk structure with adjustable angles is provided, characterized in that: an angle-adjustment unit is coupled to a bottom of a desk which is space-demanding and falls into the category of OA office furniture such that folding the desk entails: performing positional release with the angle-adjustment unit disposed below a desk board, rotating the desk board by a predetermined inclination angle, and imposing a positional restriction on the angle-adjustment unit upon completion of the angular positioning of a rotation state. Accordingly, the desks can be folded up each by a predetermined adjustable inclination angle and stacked up in a non-space-demanding direction.
