Solution Overview

Problem

Portable electronic devices with flexible displays face challenges in providing a user-friendly interface that leverages their bending characteristics, as existing solutions do not effectively utilize shape changes to control information display and user interaction.

Innovation Solution

A portable electronic device with a flexible display unit that detects shape changes and adjusts information display accordingly, using gestures such as sliding and tilting to control content on a second segment exposed when the first segment is bent or folded, allowing for intuitive interaction and efficient power use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the entire display unit is kept active to provide full information access, then information availability is improved, but power consumption increases

Engineering Contradiction:
Improveinformation availabilityVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The display unit is divided into multiple segments (first segment and second segment). When the display unit is bent or folded, only the exposed second segment remains active for information display, while the covered first segment is deactivated. This segmentation allows the system to provide necessary information access while significantly reducing power consumption by activating only the required display portion.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the display unit is bent or folded to create novel designs, then design versatility is improved, but user interface complexity increases

Engineering Contradiction:
Improvedesign versatilityVSAvoiduser interface complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display unit is designed to be flexible and capable of dynamic bending or folding. The system dynamically adjusts the active display segment based on the bending state: when bent, the second segment becomes exposed and active, providing a simplified interface; when flat, the entire display area is available. This dynamic adaptation maintains ease of operation while enabling novel design configurations.

AI summary

Provided is a mobile electronic device including: a display unit that is formed to be so flexible that at least one portion of the display unit is capable of being bent, and that is configured from a first segment of which one portion and the other portion are brought into contact with each other when the display unit is bent, and a second segment that is different from the first segment and extends from the first segment; a sensing unit that detects a shape change in the first segment due to an external force; and a controller that controls information that is output to the second segment, based on the shape change.
