Adjustable Swivel Clip for Communication Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swivel clip configurations for portable communication devices are not suitable for varied wearing arrangements, as they fail to securely attach to different sized and shaped items throughout a 360-degree rotation, leading to sliding or tilting issues due to improper grasping and poor hinge positioning.
Innovation Solution
An adjustable swivel clip with a two-piece paddle sub-assembly for linear clip length adjustment and an adjustable swivel bracket sub-assembly for linear and rotational hinge point adjustment, allowing independent configuration of clip length and hinge location to securely attach to various items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-position swivel clip is used, then the device can be attached to standard items, but it cannot reliably grip varied sized and shaped items throughout 360-degree rotation
Solution Approach 1:
The clip incorporates an adjustable paddle mechanism that allows dynamic repositioning of the clipping surface. The paddle can be rotated and locked at different angles (0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°) to adapt to various wearing positions and item orientations, ensuring reliable attachment across all 360-degree rotations while maintaining secure grip on different sized and shaped items
Solution Approach 2:
The adjustable swivel clip is designed to function with multiple types of items including belts, epaulettes, straps, and other garments or accessories. The universal design allows a single clip to serve multiple attachment purposes through its adjustable paddle and swivel bracket mechanism, accommodating varied wearing arrangements without requiring separate clip designs
2Adaptability or versatility
If the paddle is rotated beyond 30 degrees from default position, then different wearing positions can be achieved, but the clip fails to grasp the garment properly causing sliding and tilting
Solution Approach 1:
The paddle is designed with discrete angular positions (0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°) that allow it to be dynamically adjusted to different orientations. Each position is lockable to maintain secure grasping capability, eliminating the sliding and tilting problems that occur with continuous rotation in fixed-position clips
3Adaptability or versatility
If existing swivel clips are used on devices with high aspect ratios, then the device can be mounted, but the clip cannot stay in place causing sliding and tilting forward or sideways
Solution Approach 1:
The adjustable paddle can be positioned at multiple angular orientations to optimize the center of gravity alignment for high aspect ratio devices. The swivel bracket allows independent adjustment of the hinge location, enabling the clip to be configured specifically for vertical mounting scenarios where stability is critical, preventing sliding and tilting
Solution Approach 2:
The clip allows preliminary adjustment of the paddle angle and hinge position before attachment to ensure optimal stability configuration. This pre-adjustment capability enables users to configure the clip specifically for high aspect ratio devices, ensuring the center of gravity is properly positioned to prevent sliding and tilting during use
