Solution Overview

Problem

Existing methods for unrolling and rolling rollable screens in electronic devices, such as mobile phones and tablets, are limited and result in a low user experience due to reliance on manual dragging.

Innovation Solution

A method that involves starting a rollable screen motor when a target gesture meets a preset gesture, and determining a motion parameter to unroll or close the screen to specific preset states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual dragging is used to unroll and roll the rollable screen, then the device structure remains simple, but the user experience deteriorates due to limited functionality

Engineering Contradiction:

Improveuser experienceVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical dragging with an electric motor-driven system. The motor receives control signals from the controller based on gesture recognition, automatically driving the rollable screen to unroll or roll to preset positions, thereby improving ease of operation while managing device complexity through intelligent control

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service operation where the rollable screen automatically unrolls or rolls based on gesture recognition without requiring manual physical manipulation. The motor and controller work together to autonomously position the screen according to detected gestures, enhancing user experience

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If a motor-driven system is introduced to improve unrolling and rolling functionality, then user experience improves, but device complexity increases

Engineering Contradiction:

Improveunrolling and rolling diversityVSAvoidcontrol system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motor-driven system serves multiple functions: it can unroll the screen to various preset positions, roll the screen to different positions, and respond to different gesture types (swipe gestures in different directions). This multi-functionality enhances adaptability while the controller manages complexity through unified control logic

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts its behavior based on detected gestures. Different gesture types and directions trigger different motor responses, allowing the rollable screen to adapt to various user intentions. The controller dynamically controls motor operation based on real-time gesture recognition, improving versatility

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If gesture recognition is used to control the motor, then operation convenience improves, but system complexity increases

Engineering Contradiction:

Improveoperation convenienceVSAvoidgesture detection complexity

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The controller acts as an intermediary between gesture recognition and motor control. It receives gesture data from the gesture recognition module, processes this information, and translates it into appropriate motor control signals. This intermediary layer simplifies the overall system by separating detection from actuation functions

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method for unrolling and rolling a rollable screen. The method includes: starting a rollable screen motor in a case where a target gesture for a display screen meets a preset gesture; and determining a motion parameter of the rollable screen motor according to the target gesture, wherein the motion parameter is configured for indicate that the rollable screen is unrolled to a first preset state, or is closed to a second preset state.
