Finger Loop Grip for Portable Device Drop Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch screens are prone to being dropped and damaged due to inadequate grip when held in one hand, as the user's fingers are not on the edge but on the back of the device.
Innovation Solution
A finger loop made of material such as wire or silicone is affixed to the back of the case or enclosure, allowing users to place their fingers through it for improved retention and grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the device is made thinner and lighter, then the device becomes more portable and comfortable, but the grip becomes inadequate and the device becomes more susceptible to being dropped
Solution Approach 1:
The patent adds a new dimensional element (the loop structure extending from the back surface) to provide an additional grip point, transforming the single-surface grip problem into a multi-point grip solution that maintains reliability while preserving thinness
2Ease of operation
If the user holds the device with one hand using thumb and fingers on the back, then the device is easier to operate with one hand, but the grip is insufficient and the device may be dropped
Solution Approach 1:
The patent segments the grip function into two independent components: the primary grip from fingers on the back and the secondary grip from the loop structure, allowing each to perform its specific function independently while together providing reliable retention

AI summary
The invention disclosed herein is a finger loop for use with a portable electronic device case, housing or enclosure. The finger loop is formed by a strip of material such as silicone or rubber that extends away from the rear outer surface of the case, housing, or enclosure, and returns to the rear outer surface of the case, housing, or enclosure thereby forming a loop through which a user can insert at least one, or a plurality of fingers to aid in holding the device. The strip of material may include features to increase friction with the inside surface of the case or with the portable electronic device itself.
