Folding Mobile Grip Handle With Dual-Branch Finger Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handles for mobile devices are not reliable or comfortable for holding due to insufficient finger engagement, as they only provide one portion closer and one portion farther from the pivot axis for finger support.
Innovation Solution
A handle design with a first element attachable to the mobile device and a second element pivotally connected, featuring branches with two portions each, allowing fingers to be surrounded by both portions for secure grip, and including means for attachment and pivot connection to maintain the device at an angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handle with a single-portion branch structure is used, then the device structure is simple, but the finger engagement reliability is insufficient
Solution Approach 1:
The branch structure is segmented into two distinct portions: a first portion closer to the pivot axis and a second portion farther from the pivot axis. This segmentation allows each portion to engage with different parts of the finger, creating a more reliable two-point engagement system that improves holding reliability while maintaining reasonable structural complexity.
2Ease of operation
If branches with two portions are implemented, then finger surrounding and grip reliability improve, but the manufacturing complexity increases
Solution Approach 1:
The handle incorporates a pivotal connection between the first and second elements, allowing the second element to rotate relative to the first. This dynamic feature enables the handle to adapt to different finger positions and gripping styles, significantly improving ease of operation and comfortability while the manufacturing complexity remains manageable through standard hinge mechanisms.

AI summary
A handle for holding a mobile device with at least one finger has a first element attachable to a back of the mobile device, and a second element pivotally connected to the first element for pivoting around a pivot axis extending in an axial direction, the second element includes at least two branches spaced from one another in a direction which is parallel to the axial direction and each having a finger receiving opening, in a folded position of the first and second elements the second element extends along the back of the mobile device, while in a pivoted away position of the second element relative to the first element the first and second elements are located at an angle relative to one another, and each of the branches of the second elements has a first portion located closer to the pivot axis and a second portion located farther from the pivot axis and formed so that when a finger of a user is introduced into the finger receiving opening of any of the branches it is surrounded by the first portion of said branch which is located closer to the pivot axis and the second portion of the branch which is located farther from the pivot axis correspondingly from two sides.
