Foldable Desk with X-Leg Angle Adjustment to Reduce Neck Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable desks lack the ability to adjust the angle of the tabletop, which can lead to discomfort for users, especially readers, as they need to bend their neck excessively to maintain a comfortable reading posture.
Innovation Solution
A foldable desk design featuring a tabletop that can be adjusted to different angles by telescopic outer and inner legs, allowing the desk to be used in both horizontal and inclined positions, with a simple and convenient folding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a support structure with telescoping positioning function and locking mechanism is added to enable angle adjustment, then the adaptability of the desk is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the telescopic function from a complex locking mechanism by using the X-shaped leg structure itself to provide the necessary support and positioning. The legs can extend and retract without requiring additional locking components, as the crossed configuration naturally maintains structural integrity during adjustment.
Solution Approach 2:
Instead of using a traditional locking mechanism to fix the desk at specific angles, the patent inverts the approach by allowing continuous adjustment through the telescopic X-shaped legs. The structure relies on the geometric properties of the crossed legs rather than mechanical locks to maintain position.
2Reliability
If a locking mechanism with match parts is added to maintain stability at different positions, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The X-shaped leg structure serves itself by using its own geometric configuration to provide both support and positioning functions. The crossed legs naturally create stable triangular configurations at various extension levels, eliminating the need for separate locking mechanisms to maintain reliability at different angles.
3Ease of manufacture
If the desk structure is simplified to reduce complexity, then the ease of manufacture is improved, but the adaptability decreases
Solution Approach 1:
The X-shaped leg assembly performs multiple functions simultaneously: it provides structural support, enables angle adjustment through telescopic movement, and maintains stability through its crossed configuration. This multi-functionality achieves adaptability without requiring separate components for each function, keeping the overall structure simple and easy to manufacture.

AI summary
A foldable desk includes a tabletop, two outer legs, and two inner legs. An outer leg connecting rod and an inner leg connecting rod are connected to upper ends of the two outer legs and the two inner legs, respectively. Each of the two outer legs is rotatably connected to a one of the two inner legs in an X-structure. The tabletop is located between the two outer legs, and a front end of a bottom surface of the tabletop is disposed with a buckle configured to be buckled to the inner leg connecting rod when the foldable desk is unfolded for use. The two outer legs or the two inner legs are telescopic, and the tabletop is configured to be placed horizontally or switched to be placed in a state in which a front of the tabletop is lower than a rear of the tabletop.
