Touch Screen Stand with Retractable Wheels for Stability and Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stands for touch screen devices are unstable and prone to falling, especially when used in vertical or inclined positions, and their increased height due to wheels makes them cumbersome and difficult to use.
Innovation Solution
A stand with retractable wheels that can be tucked inside the base, allowing the stand to be stabilized and reduced in height, combined with a frame that supports the device and allows for adjustable positioning and locking, along with a battery connection and a writing board on the opposing side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheels are added to enable easy movement, then mobility is improved, but the base height increases making the stand cumbersome and causing tripping hazards
Solution Approach 1:
The wheels are designed to be retractable rather than fixed, allowing the stand to dynamically change its configuration. When movement is needed, wheels are extended; when stability is needed, wheels are retracted into the base, reducing the base height and eliminating tripping hazards while maintaining mobility capability
2Ease of operation
If wheels are added to enable easy movement, then mobility is improved, but the stand becomes unstable and oscillates when the screen is touched
Solution Approach 1:
The stand transitions between two stable states: wheels retracted for stability during use, and wheels extended for movement. This dynamic configuration ensures the stand is stable when needed for viewing and input, while maintaining mobility capability when required
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
The stand provides enhanced stability and reduced height, preventing it from falling when touched and allowing easy movement and positioning of the device, while maintaining portability and usability.
Implementation Method 1
the actuator drops or retracts the wheel through the support structure
Implementation Method 2
one of the parts is connected to other part of the support structure via a hinge at one end

AI summary
Disclosed is a stand for a touch screen device (118, 318), comprising a base (102, 202, 302, 402) comprising at least two wheels (104, 204, 304, 404, 504), wherein the wheels are retractable within the base. The stand also comprises a frame (106, 206, 306, 406, 506) comprising a first end (108, 208, 308, 408) and a second end (110, 210, 310, 410), attached by its first end to the base. Furthermore, the stand comprises a support for the touch screen device, attachable to the frame at the proximity of the second end of the frame. The support comprises means (116, 216, 316) for rotating the support with respect to the frame and means for locking the support with respect to the frame. The stand also comprises a battery (220, 320) and means for connecting the battery to the touch screen device.
