Adjustable Cell Phone Stand With Rotating Bracket And Sliding Jaws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cell phone stands do not optimally adjust to different phone sizes and viewing angles, and often fail to securely hold phones due to their weight and tendency to tip over.
Innovation Solution
A cell phone stand with a base and rotatable mounting bracket featuring adjustable jaws to fit various phone widths and heights, along with a mechanism to adjust the viewing angle, and gripping members for stability, allowing easy phone insertion and removal with a single hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cell phone stand uses a fixed-width mounting bracket, then the structure is simple, but it cannot accommodate cell phones of different sizes
Solution Approach 1:
The mounting bracket incorporates a movable jaw that can slide along the mounting pier, transforming a static fixed-width structure into a dynamic adjustable-width structure. This allows the bracket to adapt to different phone widths while maintaining a relatively simple overall design.
Solution Approach 2:
The mounting bracket is divided into two separate jaws (first jaw and second jaw) that can move independently relative to each other. This segmentation allows the width between the jaws to be adjusted to match different phone sizes, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If the cell phone stand uses a fixed viewing angle, then the structure is simple, but it cannot provide optimal viewing for different users
Solution Approach 1:
The mounting bracket is made rotatable relative to the base around a vertical axis, converting a static fixed-angle structure into a dynamic adjustable-angle structure. This allows users to rotate the bracket to achieve optimal viewing angles without significantly complicating the overall design.
3Stability of the object's composition
If the cell phone stand uses a narrow base, then the structure is compact, but it is unstable and tips over easily under the weight of the cell phone
Solution Approach 1:
The base transitions from a simple two-dimensional flat surface to a three-dimensional structure with legs extending downward. This dimensional change increases the effective footprint and stability without significantly increasing the horizontal footprint area, allowing the stand to resist tipping while remaining compact.
4Stability of the object's composition
If the cell phone stand uses a simple base structure, then it is easy to manufacture, but it cannot provide stable support for heavy cell phones
Solution Approach 1:
The base structure incorporates gripping members at the ends of the legs that provide localized increased friction and grip. This allows the overall base structure to remain relatively simple and easy to manufacture, while the localized gripping features provide the necessary stability and resistance to lateral displacement for supporting heavy cell phones.
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 securely holds phones of different sizes and adjusts the viewing angle for optimal visibility, preventing tipping and allowing easy phone and cable management with one hand.
Implementation Method 1
Each of the gripping members has a contact surface provided by a gripping member made of a material whose coefficient of friction, relative to a horizontal surface on which the stand is to be placed, is greater than a coefficient of friction of the material forming the first, second and third legs

AI summary
A cell phone stand has a base and a cell phone mounting bracket rotatably affixed to the base around a horizontal axis. The mounting bracket has a first jaw and a second jaw that is movable in a horizontal direction with respect to the first jaw. The first jaw has a first u-shaped channel with a first upper segment and a first lower segment. The second jaw has a second u-shaped channel with a second upper segment and a second lower segment. By adjusting the position of the jaws, the user may adjust a width between the first and upper segments, thus sizing the mounting bracket to receive a cell phone of a particular width. Even at the smallest such width, inner ends of the first and second lower segments of the u-shaped channels remain spaced from each other so as to permit the cell phone to be connected to an electrical cable while being held by the stand.
