Foldable Mobile Grip Dynamics for Slim Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device grips are bulky, compromise the sleek design, and often do not accommodate a wide range of hand sizes, while also interfering with wireless charging and requiring removal for charging.
Innovation Solution
A foldable grip integrated into the mobile device case with a base and a rotatable grip element that moves from a flat, flush position to a curved deployment for secure hand engagement, allowing for adjustable curvature and use as a kickstand without interfering with wireless charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button type accessory is attached to the back of the mobile device to provide grip, then the user's hand engagement is improved, but the device's sleek design is compromised due to the bulky appearance
Solution Approach 1:
The grip element transitions from a flat, flush position against the back panel to a deployed position that curves away to engage the user's hand. This dynamic transformation allows the grip to provide hand engagement only when needed, maintaining the sleek design when not in use.
Solution Approach 2:
The grip element utilizes the third dimension by folding away from the back panel surface, creating a curved engagement surface that extends into space. This allows the grip to provide hand engagement without adding permanent bulk to the device's profile.
2Ease of operation
If an extendable button is used to provide larger extension for hand engagement or kickstand function, then the grip comfort is improved, but the device's sleek design is further compromised due to even larger protrusion
Solution Approach 1:
The grip element can be extended to various degrees depending on the user's needs, providing adjustable comfort for different hand sizes while only protruding when deployed. When not in use, it remains flush with the back panel, avoiding permanent extension.
3Ease of operation
If a ring type grip is attached to the back of the mobile device, then hand engagement is provided, but the ring and attachment swivel protrude creating a bulky bump on the device
Solution Approach 1:
The grip element folds away from the back panel only when needed for hand engagement, rather than permanently protruding like a ring grip. This dynamic deployment eliminates the bulky bump appearance when the grip is not in use.
4Area of moving object
If a panel grip that overlays the user's finger is used, then extended gripping area is provided, but the grip becomes uncomfortable for extended use due to pressure on the hand
Solution Approach 1:
The grip element curves away from the back panel to form a concave engagement surface that cradles the user's hand, distributing pressure more evenly across the hand's surface area rather than concentrating it on a flat panel.
5Ease of operation
If separate accessories are attached to the back of the mobile device, then grip functionality is added, but the attachment mechanisms (magnetic or adhesive) interfere with wireless charging
Solution Approach 1:
The grip element is integrated directly into the back panel as a unified structure, eliminating the need for separate magnetic or adhesive attachments. This integration ensures that the grip does not interfere with wireless charging while maintaining secure attachment to the device.

AI summary
A foldable grip is provided on the back panel of a mobile device to enable comfortable and secure holding of the device even during extended use. The grip structure has two main parts, a base that is integrally connected to the panel, and a grip element that is mounted to the base. The grip element moves from a resting position that is flat and flush with the panel of the mobile device to a deployed position in which at least a portion of the grip element folds and curves away from the base to provide a curved surface for a user’s hand to engage. The flat resting position of the trip element ensures that the slim form factor of the device is not disrupted and that a sleek appearance is
