Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices are often used while being held, causing inconvenience, and when placed flat on a surface, it is difficult to view the screen at an optimal angle, leading to delays in communication and reduced usability.
Innovation Solution
A mobile device display stand structure with a shaft and levers that can be adjusted to any angle between 0-180 degrees, using a non-permanent fixing method, allowing for flexible positioning and secure attachment of devices at desired heights and angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile device is held in hand for viewing, then the viewing angle and accessibility are improved, but the user's hands are occupied and communication efficiency deteriorates
Solution Approach 1:
The stand structure allows the mobile device to support itself independently on a horizontal surface, freeing the user's hands for other operations. The device maintains its own viewing angle through the lever-shaft mechanism without requiring continuous manual adjustment.
Solution Approach 2:
The stand is divided into separate functional components: levers for angle adjustment, a shaft for rotational movement, and a bending portion for stability. This segmentation allows each component to perform its specific function efficiently while working together to solve the overall problem.
2Stability of the object's composition
If the mobile device is placed flat on the desktop, then the device is stable and hands-free, but the viewing angle is poor and usability deteriorates
Solution Approach 1:
The stand transitions from a static flat position to a dynamic adjustable structure. The levers can be manually positioned at different angles relative to the shaft, allowing the device to be tilted to optimal viewing angles while maintaining stability through the bending portion's attachment mechanisms.
Solution Approach 2:
The stand structure uses asymmetric lever arrangements where the first and second levers are positioned at different orientations relative to the shaft. This asymmetry enables multi-directional angle adjustment, providing flexible viewing options while maintaining structural balance and stability.
3Reliability
If the stand structure is made rigid and fixed, then the viewing angle is stable and reliable, but the adaptability to different viewing preferences deteriorates
Solution Approach 1:
The stand incorporates movable levers that can be adjusted to different angular positions relative to the shaft, then fixed in place using the bending portion with non-permanent fixing methods. This allows the structure to be dynamically reconfigured for different viewing preferences while maintaining reliable stability once positioned.
Solution Approach 2:
The stand allows users to change the angular parameters of the levers relative to the shaft and to each other. By adjusting the included angle between levers and their orientation to the shaft, users can optimize the viewing angle for different scenarios while the structure maintains reliability through its mechanical design.
4Weight of moving object
If the levers are made lightweight for portability, then the ease of carrying is improved, but the structural strength to support the device deteriorates
Solution Approach 1:
The stand levers and shaft are constructed from composite materials that combine light weight with high strength-to-weight ratio. This allows the structure to remain portable and easy to carry while maintaining sufficient structural strength to support the mobile device at various angles without deformation or failure.

AI summary
A mobile device display stand structure includes: a shaft driven and rotated by applying a critical moment greater than a resistance of the shaft to overcome the resistance of the shaft; and a first lever and a second lever connected to the shaft separately. The first lever and the second lever use the shaft as a fulcrum and flip over relative to each other by the shaft to define an included angle, and the first lever and the second lever are plate-shaped bodies. When the included angle is 0-180 degrees, the gravity of the first lever generates a first moment relative to the shaft or the gravity of the second lever generates a second moment smaller than the critical moment relative to the shaft, such that the first lever or the second lever cannot be rotated relative to the shaft and the included angle is kept constant.
