Solution Overview

Problem

Flexible display devices bend under gravity, making it difficult for users to perform touch operations due to their flexible nature, which affects the stability and accuracy of interactions.

Innovation Solution

A widget displaying method and apparatus that determines a force-bearing area on the flexible display screen based on pressure bearing capacity information, allowing a touchable widget to be displayed on areas with high anti-deformation and pressure bearing capacities, ensuring stable operation by avoiding the contact area with the holding object and adjusting for deformation and stretching conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the flexible display device is held in one hand while performing touch operations, then portability and ease of operation are improved, but the device bends under gravity making touch operations difficult and inaccurate

Engineering Contradiction:
Improveease of operationVSAvoidaccuracy of touch operations
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent dynamically adjusts the widget display area based on the real-time bending state of the flexible display device. By detecting the curvature and deformation of the display surface, the system adapts the widget position and shape to remain within the force-bearing area, ensuring accurate touch operations despite device flexing during single-hand holding

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent identifies and utilizes the force-bearing area (typically the center region) of the flexible display device where the display maintains its flatness and pressure-bearing capacity. Widgets are specifically positioned within this local region that resists deformation, while other areas of the display may bend without affecting the operational stability of the interface

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the flexible display device uses a fully flexible screen, then foldability and portability are improved, but the display deforms under gravity affecting touch operation stability

Engineering Contradiction:
ImprovefoldabilityVSAvoidstability of display surface
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system continuously monitors the display surface deformation and dynamically adjusts the widget display area accordingly. When the device is folded or bent, the system detects the changed geometry and repositions widgets to areas that maintain structural stability, allowing the display to be flexible while preserving operational reliability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent distinguishes between different regions of the flexible display device, identifying the force-bearing area that maintains stability during folding and bending. The widget interface is confined to this stable local region, allowing the rest of the display to flex and fold without compromising the stability of the interactive area

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the widget is displayed on the flexible display screen, then user interface functionality is provided, but the widget position shifts due to display deformation making precise touch difficult

Engineering Contradiction:
Improveinterface functionalityVSAvoidprecision of touch input
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent implements real-time detection of display surface curvature and deformation, using this information to dynamically recalculate and reposition the widget display area. This ensures that the widget remains within the force-bearing area where touch precision is maintained, even as the display deforms during flexing or folding operations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The widget interface is specifically positioned within the force-bearing area of the flexible display device where the surface maintains its flatness and dimensional stability. By confining the interactive elements to this localized stable region, the system preserves touch input precision while allowing the rest of the display to deform

Inventive Principle:
Principle #3Local quality
