Stand for a portable device with a graphic user interface display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices with graphic user interfaces, such as laptops and tablets, often pose ergonomic challenges due to insufficient display height and difficulty in maintaining a suitable viewing angle, leading to neck complaints and discomfort during prolonged use.
Innovation Solution
A lightweight and compact stand that allows adjustable orientation of the display screen between landscape and portrait positions, with a device holder connected to a carrier panel that can pivot and rotate, enabling easy adjustment without removing the device from the stand, and a magnetic connection system for secure and adjustable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display position is kept low for portability, then the device remains compact and easy to carry, but neck complaints and ergonomic problems occur during prolonged use
Solution Approach 1:
The stand employs a hinge mechanism that allows the carrier panel to pivot between a flat transport position and an elevated support position. This dynamic transformation enables the display to be positioned at an ergonomically suitable height during use while maintaining a compact profile for portability, directly resolving the contradiction between low display position for portability and high display position for ergonomics
2Device complexity
If the display orientation is fixed, then the device structure remains simple, but the display cannot be adjusted to match desired viewing angles
Solution Approach 1:
The device holder is connected to the carrier panel via a rotation mechanism that enables the held device to rotate between landscape and portrait orientations. This dynamic rotational capability allows the display orientation to adapt to different viewing preferences and usage scenarios while maintaining a relatively simple overall structure, resolving the contradiction between structural simplicity and viewing angle adaptability
Solution Approach 2:
The stand is divided into functionally independent components: a base support structure, a pivoting carrier panel, and a rotating device holder. This segmentation allows each component to perform its specific function (support, position adjustment, orientation adjustment) independently, enabling versatile display orientation adjustment without requiring complex integrated mechanisms
3Ease of operation
If the stand is made adjustable for different positions and orientations, then ergonomic use is enabled, but the stand becomes heavier and less compact
Solution Approach 1:
The stand uses a hinge mechanism that allows the carrier panel to pivot between flat and elevated positions, and a rotation mechanism that enables the device holder to rotate between orientations. These dynamic mechanisms provide full adjustability for ergonomic use while keeping the stand lightweight and compact, as the mechanisms rely on simple mechanical joints rather than heavy motorized systems
Solution Approach 2:
The stand employs thin, flat panels and lightweight structural elements that can be easily pivoted and rotated. The carrier panel and device holder are designed as thin components that provide necessary structural strength for position adjustment while minimizing weight, enabling ergonomic adjustability without significantly increasing the stand's mass

AI summary
A stand for supporting a portable display device with a graphic user interface display screen in a generally upright position leaning backward. The stand has a carrier panel and a support pivotable relative to the carrier panel about a pivot axis, between a transport position and a support position for supporting the carrier panel in an orientation projecting obliquely upward from the support surface. An angle setting member holds the carrier panel and the support at a set mutual angle when the support is in its support position. A device holder is attached or attachable to the device in a fixed position and adjustably connected to the carrier panel for guided movement in a direction perpendicular to the pivot axis and in rotational sense about an axis of rotation perpendicular to the carrier panel.
