Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device mounting systems for vehicles and other moving platforms face challenges in providing stability under rotational and vibrational loads, leading to potential re-adjustment needs during operation, which can distract the user and compromise safety.
Innovation Solution
A mounting system with a clamp assembly and connecting elements featuring geometric inhibitors such as teeth or splines that engage to prevent rotation, combined with a ball mount and insert for increased holding force and energy absorption, allowing for secure positioning and adjustment of mobile devices without sacrificing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the mobile device is cantilevered away from the mounting system or supported at only one end of the clamping component, then the mounting system can be simpler in structure, but the rotational stability deteriorates under vibration and rotational forces
Solution Approach 1:
The connecting element incorporates asymmetric geometric inhibitors (teeth or splines) that create directional resistance to rotation. These inhibitors are positioned and shaped to provide maximum rotational stability while maintaining a relatively simple mounting structure, resolving the contradiction between structural simplicity and rotational stability.
2Stability of the object's composition
If geometric inhibitors (teeth or splines) are added to the connecting element to prevent rotation, then rotational stability improves, but the device complexity increases
Solution Approach 1:
The geometric inhibitors (teeth or splines) are integrated directly into the connecting element as a unified structure rather than being separate components. This merging of anti-rotation features with the connecting element itself provides rotational stability while minimizing the increase in overall device complexity.
3Stability of the object's composition
If the clamp assembly components are compressed against the connecting element to increase holding force, then the rotational stability improves, but the freedom-of-angular rotation during assembly decreases
Solution Approach 1:
The clamp assembly is designed with dynamic characteristics that allow freedom of angular rotation during the assembly process when compression force is not yet applied. Once the clamp bodies are compressed against the connecting element, the geometric inhibitors engage to provide rotational stability. This dynamic transition from flexible assembly to rigid operation resolves the contradiction between ease of assembly and rotational stability.
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 solution enhances rotational stability and holding force, preventing self-adjustment of the mounting system under load, thus improving user safety by maintaining device position and orientation without requiring frequent re-adjustments during vehicle operation.
Implementation Method 1
The first plurality of engaging elements may be configured to engage with a clamp body to substantially prevent rotation of the clamp body with respect to the connecting element
Implementation Method 2
a ball mount and insert for increased holding force and energy absorption, allowing for secure positioning and adjustment of mobile devices
Implementation Method 3
The insert may be formed from a different (e.g., softer) material than the ball mount and may be configured to engage with the protrusions and/or indentations in the ball to further increase the holding force. The insert may be recessed into the inner surface of the clamp bodies and may include clocking features to prevent relative rotation between the insert and the clamp bodies. In some embodiments, the insert may be formed from a different (e.g., softer) material than the ball mount and may be configured to engage with the protrusions and/or indentations in the ball to further increase the holding force.

AI summary
A mounting system for supporting an electronic device includes a mount and a connecting element coupled to the mount. The connecting element may include an interface body and a first plurality of engaging elements. The interface body may include a first body portion and a second body portion, and extend axially between an axial end of the connecting element and the first body portion. The second body portion may have a reduced diameter relative to the first body portion. The first plurality of engaging elements may be configured to engage with a clamp body to substantially prevent rotation of the clamp body with respect to the connecting element.
