Rotatable Mounting Arms for Centered Phone Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for electronic devices, such as mobile phones, often fail to securely attach without obstructing buttons or ensuring proper orientation and centering, especially when used with head-mounted displays (HMDs).
Innovation Solution
A mounting device featuring rotatable arms with engagement members made of high-friction materials, such as hard rubber grips, and a coiled spring mechanism that securely holds electronic devices like mobile phones in a horizontal orientation without touching buttons, using a housing with a screw thread and washer for attachment, ensuring centering and horizontal alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing mounting devices use simple clamping mechanisms, then the device complexity is reduced, but the mounting security and reliability deteriorate
Solution Approach 1:
The mounting device is divided into two separate arms (first arm and second arm) that can independently rotate around a common axis. Each arm has its own engagement members, allowing independent adjustment and secure clamping of the electronic device from multiple directions, thereby improving mounting security without requiring a single complex mechanism
Solution Approach 2:
The arms are designed to be rotatable around a common axis, providing dynamic adjustment capability. This allows the engagement members to be positioned at optimal locations for different device sizes and shapes, enhancing mounting reliability while maintaining a relatively simple structural design
2Reliability
If engagement members are positioned to securely grip the device, then the mounting security is improved, but the risk of obstructing buttons or controls increases
Solution Approach 1:
The engagement members are designed with localized high-friction surfaces (such as rubber grips or textured surfaces) at specific contact points, providing secure grip only where needed. The arms and other portions of the device maintain smooth surfaces that do not interfere with buttons or controls, thus achieving secure gripping without button obstruction
Solution Approach 2:
The rotatable arms allow the engagement members to be preliminarily positioned at optimal locations before clamping. This enables the high-friction surfaces to contact the device at points that provide secure grip while avoiding areas with buttons or controls, preventing obstruction before the clamping action occurs
3Adaptability or versatility
If the mounting device uses a fixed orientation structure, then the manufacturing precision is improved, but the adaptability to different device orientations deteriorates
Solution Approach 1:
The arms are designed to rotate around a common axis, allowing dynamic adjustment of the engagement members' positions and orientations. This enables the mounting device to adapt to different electronic device orientations and configurations while the rotational mechanism itself can be manufactured with standard precision tolerances, maintaining manufacturing feasibility
Solution Approach 2:
The mounting device structure with rotatable arms and adjustable engagement members can accommodate multiple device types, sizes, and orientations. This universal design achieves adaptability without requiring complex custom-manufactured components for each specific application
4Ease of operation
If the arms are made longer to increase engagement distance, then the ease of operation is improved, but the device dimensions and space requirements increase
Solution Approach 1:
The engagement members incorporate localized high-friction surfaces (such as rubber grips or textured surfaces) at the contact points with the electronic device. This concentrates the gripping function at specific locations, providing sufficient engagement force and ease of operation without requiring the arms to be excessively long
