Solution Overview

Problem

Existing flexible electronic devices with foldable displays lack efficient mechanisms to dynamically adjust display modes based on the device's posture and user interaction, leading to suboptimal user experience.

Innovation Solution

Incorporating first and second inertial sensors in the device housings, along with a processor, to identify angles and postures, allowing for dynamic switching between display modes, including activating or deactivating displays and adjusting modes based on inertial data and application usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If display modes are fixed without dynamic adjustment, then device structure is simple, but user experience is suboptimal

Engineering Contradiction:

Improvedisplay mode adaptabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic display mode adjustment by enabling the display to switch between different modes (full screen, split screen, folded mode, unfolded mode) based on real-time detection of device posture through inertial sensors and folding state through hinge sensors, making the display system adaptable rather than fixed

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system continuously monitors device posture via inertial sensors and folding state via hinge sensors, processes this feedback information through the processor, and automatically adjusts display modes accordingly, creating a closed-loop control system that adapts to user needs without manual intervention

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If multiple sensors and processing mechanisms are added for dynamic display adjustment, then user experience improves, but device complexity increases

Engineering Contradiction:

Improvedisplay mode adaptabilityVSAvoidsensor and processing system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The inertial sensors and hinge sensors serve multiple functions: detecting device posture, determining folding state, and triggering display mode changes, allowing a single sensor system to handle multiple detection tasks rather than requiring separate specialized sensors for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functions of posture detection (inertial sensors) and folding state detection (hinge sensors) into a unified display control system managed by the processor, integrating multiple sensing and control functions into a coordinated system rather than separate independent mechanisms

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An electronic device includes: a first housing including a first surface and a second surface opposite to the first surface; a second housing including a third surface and a fourth surface opposite to the third surface; a first display on the first and third surfaces; a second display on the second surface; a first inertial sensor in the first housing; a second inertial sensor in the second housing; and at least one processor. The at least one processor is configured to: identify, using the first and second inertial sensors, that an angle between a first direction in which the first surface faces and a second direction in which the third surface faces is within a designated range, identify that first data, which is related to a posture of the electronic device and is identified using the second inertial sensor, is within a first range, and change a display mode of the second display.
