Mobile Phone Back Recesses for Wider One-Handed Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen full-screen mobile phones with widths greater than 90 mm are inconvenient to hold with one hand, limiting the usability of wider screens.
Innovation Solution
The mobile phone design incorporates recesses on the back to accommodate multiple fingertips, with strip-shaped protrusions at the opening, allowing for a one-handed grip, and optionally includes a foldable bracket or handle for enhanced grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the width of the mobile phone body is increased to accommodate a wider screen, then the visual effect and screen real estate are improved, but the ease of one-handed holding deteriorates
Solution Approach 1:
The patent introduces a recess structure on the back surface of the mobile phone, creating a third-dimensional feature that provides additional grip points for fingers. This dimensional addition allows the phone to maintain a wider screen width while providing ergonomic support for one-handed holding through the recess accommodation of 2-4 fingers.
2Area of stationary object
If the screen width is increased beyond 90mm, then more content can be displayed and visual experience is improved, but the phone becomes difficult to hold with one hand
Solution Approach 1:
The patent applies local quality by creating a recess with specific dimensional parameters (length 13-80mm, width 13-25mm, depth 5-15mm) at a specific location on the phone back. This localized structural modification provides targeted finger accommodation without affecting the overall screen width, enabling both large display area and comfortable one-handed holding.

AI summary
Disclosed is a mobile phone. In the mobile phone, one to four recesses are formed in a back of the mobile phone, the recesses are sized enough to allow one to four fingertips to reach into the recesses, such that the fingertips can cooperate with a palm of the same hand to hold the mobile phone by one hand, while a thumb of the hand can still click or slide a screen freely. Due to a change in a manner of holding the mobile phone by one hand, a screen width of a full-screen mobile phone can be designed to be wider. The wider screen displays the same content, and characters or image elements appear larger, which obviously improves a visual effect and is also conducive to relieving eye fatigue.
