Adjustable Desk Panels for Correct Posture and Reduced Neck Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks lead to incorrect posture due to the need to bend the upper body, causing neck and shoulder pain, especially for users who sit for long periods, as they do not allow for optimal alignment of the head and body during tasks like reading or writing.
Innovation Solution
A desk design featuring an upper panel, a movable panel, and a vertical panel that can be adjusted to various positions, including inclined, vertical, and parallel configurations, allowing users to maintain correct posture by minimizing head tilt and eye movement, with adjustable height and slant angles to accommodate different body types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the horizontal panel is fixed to the support legs, then the desk structure is simple and stable, but the user's upper body must bow down causing incorrect posture and neck, shoulder, waist pain
Solution Approach 1:
The desk surface is divided into multiple independent panels: a fixed horizontal panel and a movable panel that can rotate independently. This segmentation allows the movable panel to adjust to the user's line of sight while the horizontal panel remains stable, resolving the contradiction between posture correctness and structural simplicity.
Solution Approach 2:
The movable panel is designed to rotate around a rotation shaft, transforming from a static fixed panel to a dynamic adjustable panel. This dynamic feature enables the panel to adapt to different user heights and viewing angles, improving posture correctness while maintaining overall structural stability through the rotation mechanism.
2Ease of operation
If the horizontal panel is configured to rotate around a rotation shaft to adjust the slant angle, then the bent degree of the user's upper body is eased, but the upper body must still bow down to use the desk
Solution Approach 1:
The desk surface is divided into a fixed horizontal panel and a separate movable panel that rotates independently. This segmentation allows the movable panel to be adjusted to a higher position and angle, enabling the user to view it without bowing down, while the horizontal panel remains stable for placing materials.
Solution Approach 2:
The solution moves from a single-plane rotation to a two-panel configuration where the movable panel can be positioned in both vertical and horizontal dimensions. This dimensional adjustment allows the panel to align with the user's line of sight without requiring the user to bend their upper body.
3Object-affected harmful factors
If a movable panel and vertical panel are added to allow correct posture, then neck and shoulder strain is reduced, but the device complexity increases
Solution Approach 1:
The desk is segmented into a fixed horizontal panel for material placement and a movable panel that rotates to align with the user's line of sight. This segmentation eliminates the need for the user to bow down or strain their neck, as the movable panel can be positioned at the appropriate viewing angle.
Solution Approach 2:
The movable panel serves multiple functions: it acts as a viewing surface for the user, provides support for reading or writing materials, and can be adjusted to different angles. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary
A desk according to one embodiment of the present invention includes an upper panel (120), a support leg (110), a support member (130), a movable panel (140) and a vertical panel (150). The upper panel is coupled to an upper end of the support leg. The support member extends from the upper panel. The movable panel has an upper end movable along the support member and a lower end movably placed on the upper panel. The movable panel is movable between a first position inclined with respect to the upper panel and a second position vertical to the upper panel and between the first position and a third position parallel to the upper panel. The vertical panel is rotatably joined to the support member. A lower end of the vertical panel is movably placed on the movable panel. The vertical panel moves along with the movement of the movable panel.
