Portable Sit-Stand Table With X-Frame Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional desks and tables do not effectively address the health issues associated with prolonged sitting, such as eye, neck, and back strain, and do not provide easy access to adjustable working surfaces for both seated and standing positions, especially for healthcare workers.
Innovation Solution
A lightweight, portable table with an X-shaped elevation structure that can be easily extended to a maximum height of approximately one foot, featuring a compact collapsed configuration, spring-assisted deployment, and a simple L-shaped base rail design for easy installation and use, allowing users to switch between seated and standing positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional desk or table is used, then the working surface height is fixed, but this causes eye, neck, and back strain for seated users and does not allow standing work
Solution Approach 1:
The table is divided into separate components: a table top, an X-shaped support structure with multiple rods, and a base. This segmentation allows the support structure to be collapsed into a compact configuration for easy storage and transport, while still providing full height adjustment capability when deployed. The locking mechanism segments the adjustment function, allowing the table to be locked at various heights.
Solution Approach 2:
The X-shaped support structure incorporates a dynamic locking mechanism that allows the table height to be adjusted and locked at multiple positions. The locking/release handles enable the user to dynamically change the table height from a collapsed state (less than 4 inches) to an extended working height (up to one foot or more), providing adaptability between seated and standing work positions.
2Ease of operation
If a portable table with height adjustment is designed, then health benefits are improved, but the table becomes heavier and harder to transport
Solution Approach 1:
The base rails are designed as L-shaped structures rather than symmetric rectangular frames, reducing material usage and overall weight while maintaining structural integrity and stability. This asymmetric design provides sufficient support for the table top and adjustment mechanism without the excess weight of a complete rectangular frame.
Solution Approach 2:
The X-shaped support structure is designed to collapse into a compact nested configuration during transport, with the support rods fitting within each other and the overall structure reducing to a small footprint. This nesting capability significantly reduces the space and effort required for transport while maintaining full functionality when deployed.
3Ease of manufacture
If the table structure is simplified for easy portability, then ease of operation is improved, but manufacturing precision and structural strength may be compromised
Solution Approach 1:
The locking mechanism is designed with preliminary positioning features that guide the support rods into correct alignment and locking positions. The notches and engagement surfaces are pre-formed to ensure proper positioning, eliminating the need for complex adjustment procedures while maintaining structural integrity and strength.

AI summary
A lightweight and portable table that during its use can be set upon a desk or another table, and which has an upwardly extendable top surface with a maximum elevation of approximately one foot. It allows people working in a seated position at their desk to adjust the working top surface thereof to a more comfortable position, and alternatively allow them to comfortably work from the elevated top surface while in a standing position. The portable table is easy to manage, movable from one support surface to another with little effort, spring-assisted with load during up and down deployment, and it promotes improved health and welfare of its users. Applications include, but are not limited to, home use, business use, and use by healthcare workers who need prompt access to instruments and devices while in both sitting and standing positions when caring for different patients during a work day.
