Adjustable Multi-Degree-Freedom Stand for Uneven Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic device stands fail to accommodate uneven or non-solid surfaces, limiting their usability in various settings such as beds, outdoor locations, and positions other than lying on the back, as they have fixed legs that require a flat surface for support.
Innovation Solution
A supporting device with a main shaft, swing arms, adjustable legs, and grippers that allow for independent movement and adjustment in multiple degrees of freedom, enabling the device to be used on uneven surfaces and in different orientations, including lying on the side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed legs are used in the stand, then the structure is simple and stable on flat surfaces, but the stand cannot accommodate uneven or non-solid surfaces
Solution Approach 1:
The patent applies the dynamics principle by making the legs adjustable and movable rather than fixed. Each leg can be independently positioned and angled to adapt to uneven surfaces, transforming a static structure into a dynamic one that can respond to varying surface conditions while maintaining stability
2Adaptability or versatility
If fixed orientation legs are used, then the manufacturing is simple, but the device cannot be used in positions other than lying on the back
Solution Approach 1:
The legs are designed with adjustable orientation capabilities, allowing them to be positioned at different angles and directions. This dynamic adjustment feature enables the device to be used in various positions (lying on back, side, etc.) while the manufacturing process remains relatively simple through modular construction
3Adaptability or versatility
If adjustable legs are added to accommodate uneven surfaces, then surface adaptability improves, but the device complexity increases
Solution Approach 1:
The stand is divided into independent leg segments that can be individually adjusted. Each leg operates independently with its own adjustment mechanism, allowing for localized adaptation to surface irregularities without requiring complex coordinated movement of the entire structure
Solution Approach 2:
The legs incorporate dynamic adjustment mechanisms that allow users to modify leg position and angle in response to uneven surfaces. This dynamic capability enables the stand to adapt to various surface conditions while maintaining a relatively simple overall structure through modular design

AI summary
A supporting device is configured to hold and support a portable electronic device. The supporting device includes a main shaft, a plurality of swing arms, a holder, and a plurality of adjustable legs. The portable electronic device is configured to lean against the main shaft. The swing arms are pivotally coupled to two opposite ends of the main shaft and configured to rotate relatively to the main shaft. The holder is configured to receive an edge of the portable electronic device. The swing arms are slidably connected to the holder for adjusting a distance between the main shaft and the holder through the rotating of the swing arms. The adjustable legs are pivotally coupled to the two opposite ends of the main shaft. The adjustable legs are independently movable in at least two degrees of freedom.
