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 pocket attaches to the back of the case between the camera and the charging port. It can prop the phone up, enhance grip, and has a strap that allows the phone to rest on the hand without gripping it tightly. The pouch can be quickly released to wirelessly charge the phone or mounted in a car holder.

2. Device Strap with Sliding Clip Attachment Mechanism for Tripod Connectivity

Vitec Holdings Italia SRL, 2022

A device strap with an attachment mechanism that allows users to securely hold electronic devices and attach them to tripods or other accessories. The strap clips onto the device case and can slide along a fixed path to expose a clip that connects to a tripod. This provides a more secure grip on the device and allows it to be conveniently attached to tripods and other accessories.

3. Elastic Mobile Device Cover with Interchangeable Rigid Male Connector Parts

FRUITSHOP INTERNATIONAL CO., LTD., 2022

A protective cover for mobile devices like smartphones that have replaceable male connector parts. The cover has an elastic main body that fits around the device. The main body can connect to a first rigid male part or a second rigid male part. These male parts have different connector designs to match different female parts on mounting accessories. The main body has openings and engagement features to secure the male parts in place. This allows the user to swap the male connector to match different mounting systems without changing the main cover.

4. Attachable Device with Hinged and Rotatable Extendable Member for Mobile Devices

Hip Innovations, LLC, 2021

Versatile device attachable to mobile devices like cell phones. It has an extendable member hinged to a base that attaches to the mobile device. The extendable member can pivot and rotate to create a stand, grip, hook, and ring for holding, viewing, hanging, and spinning the mobile device. The device attaches to the mobile device via a fastener like adhesive or hook and loop.

5. Cellular Device Case with Integrated Mount, Slidable Attachment Hooks, and Suction Cup Mechanism

Guadalupe Reyes, 2021

Cellular device case with a built-in mount that allows hands-free viewing and use of a smartphone. The case has a back portion and sidewalls that surround and fit a smartphone. Slidable attachment hooks on the sidewalls secure the phone in place. The case has a suction cup on the back, buttons to operate the phone's buttons, and an aperture for the camera. It can also have a protective screen.

6. Mobile Phone Case with Integrated Rotatable Bracket and Connecting Frame

GUANGZHOU XIONGDA ELECTRONIC TECH CO LTD, GUANGZHOU XIONGDA ELECTRONIC TECHNOLOGY CO LTD, 2021

Mobile phone case design with integrated bracket that prevents detachment and improves durability compared to separate brackets. The case has an outer frame with integrated frame, connecting piece, and bracket. The bracket attaches to the connecting piece and can rotate around it. This allows winding the bracket around the case for support without adhesives or rotating shafts. The integrated design prevents bracket detachment and provides a secure bracket that can rotate around the case.

7. Mobile Phone Connection Frame with Fixing Frame and Clamping Assembly

SHENZHEN WEIJIAMEI RUBBER & PLASTIC ELECTRONICS CO LTD, 2020

A mobile phone connection frame with improved stability and security compared to traditional snap-on or adhesive frames. The frame has a fixing frame, a mobile phone bracket, and a clamping assembly. The phone bracket attaches to the fixing frame. The clamping assembly is mounted on the fixing frame. This provides a sturter, more stable connection for the phone since it is clamped in place rather than just snapped on or held by adhesive.

8. Mobile Device Protective Cover with Cavity-Stored Dry Adhesive Strips for Hands-Free Mounting

Richard G. Ramirez, Marissa L. Gaster, Brent Kleinman, 2019

This is a protective cover for mobile devices with dry adhesive strips that allow hands-free mounting on objects. The cover has a cavity on the backside to store the adhesive strips when not in use. The adhesive strips can be accessed, peeled off, and pressed against a target surface to mount the device hands-free.

9. Protective Electronic Device Cover with Integrated Functional Components and Interface Access

Samsung Electronics Co., Ltd., 2019

A protective cover for an electronic device that allows the device to perform additional functions when mounted inside the cover. The protective cover has a mounting surface for receiving the electronic device, a case frame that combines with the mounting surface, and electronic components sandwiched between the frames. These components include sensors, connectors, speakers, etc. that can operate when powered and controlled by the device inside. The cover can have buttons to press the device buttons, ports to access device ports, holes for jacks, etc.

10. Protective Case with Removable Mounting, Anti-Slip Inserts, and Rear Access Openings

ROKFORM IP LLC, 2018

Protective case system for smartphones and tablets with features like removable mounting, anti-slip inserts, and rear device access. The case has a shell with sidewalls that enclose the device, openings for controls, and rear openings for access. It has an attachment region for a removable mount allowing securement to surfaces. The shell also has a non-slip insert with a magnet for surface adherence.

11. Protective Cover Assemblies with Retractable Dry Adhesive Strips for Mobile Devices

Richard G. Ramirez, Marissa L. Gaster, Brent Kleinman, 2018

Protective cover assemblies for mobile computing devices that enable hands-free viewing by allowing mounting of the device to objects. The protective covers have dry adhesive strips on the back that stick to surfaces. When not in use, the adhesive strips can be stored in covered cavities or movable compartments to protect them from damage or dirt.

12. Cell Phone Case with Sliding Support Members and Elastic Front Connection

Chang Seob YOO, 2016

Cell phone case with a slim, compact design that allows accommodating phones of different sizes and thicknesses without increasing the case thickness or requiring multiple fixing mechanisms. The case has support members with sliding guides to grip the phone sides and front. A thin elastic connection between the front supports fixes the phone width. This allows tight fixing with reduced case thickness versus separate side and front springs. It also enables moving the lower support to avoid battery port obstruction.
