Solution Overview

Problem

The increasing screen-to-body ratio in smartphones with arc-shaped screens compromises the size of the obverse-side display area, restricts operations, and affects the overall display effect due to the arc-shaped screen's large radius and limited obverse-side display space.

Innovation Solution

A mobile terminal design featuring a middle frame with grooves for securing an arc-shaped display module and battery cover, utilizing sloping fastening planes and auxiliary blocks for assembly, along with an AI chip to control pressure-sensitive components for optimal display and functionality based on user posture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If an arc-shaped screen is used to increase the screen-to-body ratio, then the screen-to-body ratio is improved, but the obverse-side display area becomes relatively small

Engineering Contradiction:
Improvescreen-to-body ratioVSAvoidobverse-side display area
Core Design Contradiction:
Area of moving objectVSArea of stationary object

Solution Approach 1:

The display module extends from the obverse side to the side frame, utilizing the side dimension of the terminal device. This allows the arc-shaped display area to wrap around the side wall, effectively using three-dimensional space rather than being confined to the two-dimensional obverse surface, thereby increasing the overall screen-to-body ratio without significantly reducing the obverse-side display area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the arc-shaped screen has a large radian to enable participation in display, then the display coverage is improved, but the obverse-side display area becomes smaller

Engineering Contradiction:
Improvedisplay coverageVSAvoidobverse-side display area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The display area is segmented into distinct regions: an obverse-side display area for primary content and an arc-shaped display area wrapping around the side frame for additional display functions. This segmentation allows each region to serve specific purposes, with the arc-shaped portion providing extended display coverage without encroaching on the main obverse-side display space.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the arc-shaped display area is used for horizontal operations, then the display versatility is improved, but the operation flexibility is restricted

Engineering Contradiction:
Improvedisplay versatilityVSAvoidoperation flexibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The terminal device dynamically adapts its display configuration based on the holding posture detected by pressure-sensitive components. When held horizontally, the arc-shaped display area becomes active for additional operations; when held vertically, the system switches to conventional operation modes. This dynamic adaptation allows the device to provide versatile display options while maintaining operational flexibility across different usage scenarios.

Inventive Principle:
Principle #15Dynamics

AI summary

This application provides a mobile terminal. The mobile terminal includes a middle frame, a battery cover, and a display module. A first groove and a second groove are provided on each of a left-side wall and a right-side wall of the middle frame, and the first groove and the second groove share a part of the side wall. The display module is correspondingly disposed in one of the first grooves, and the battery cover is correspondingly disposed in one of the second grooves. The display module includes an obverse-side display area and arc-shaped display areas located on two sides of the obverse-side display area, indent surfaces of the two arc-shaped display areas are disposed opposite to each other, and a vertical distance between end portions that are of the two arc-shaped display areas and that are away from the obverse-side display area is less than a maximum vertical distance between the two arc-shaped display areas. In this way, the arc-shaped display areas enclose a widest part of the entire mobile terminal. In addition, the arc-shaped display areas have sufficient sizes to display independently, thereby improving a display effect of the entire mobile terminal.
