Phone Case Mount Systems
18 patents in this list
Updated:
Mobile phone case mount systems must balance multiple mechanical constraints: they need to withstand repeated attachment/detachment cycles, support loads up to 300g at various angles, and maintain reliable connections despite daily wear. Current mounting solutions show failure rates of 12-15% within the first year, primarily at connection points and adhesive interfaces.
The core engineering challenge lies in creating secure mounting mechanisms that maintain device protection while enabling quick release and repositioning—all within the strict dimensional constraints of modern smartphone form factors.
This page brings together solutions from recent research—including sliding rail systems with mechanical locks, multi-position hinged mounts, hybrid adhesive-mechanical attachments, and modular connector designs. These and other approaches focus on achieving reliable mounting while preserving case thickness profiles and enabling compatibility across device generations.
1. Removable Mobile Phone Case Pocket with Adjustable Strap and Quick-Release Mechanism
Marisa A. James, 2022
A removable pocket that attaches to a mobile phone case to provide an add-on pouch for holding personal items like credit cards, money, and keys.

The integrated design prevents bracket detachment and provides a secure bracket that can rotate around the case.
9. Finger Attachment System with Secure Grip Mechanism for Portable Device Integration
ANDREW JACOB FREIMUTH, 2020
A finger attachment system for portable devices that improves ergonomics and ease of use while reducing the risk of dropping the device. The system attaches to the back of a device like a smartphone and wraps around the user's finger, providing a secure grip with reduced strain compared to holding the device in the hand. The attachment adds minimal bulk and weight to the device.
10. Slim Smartphone-Attachable Credit Card Holder with Flexible Snap-Back Clip Mechanism
NITE IZE, INC., 2020
