Solution Overview

Problem

Existing electronic devices with flexible displays face challenges in efficiently displaying notifications on curved or folded surfaces, leading to potential obscuration and distortion, which affects user visibility and interaction.

Innovation Solution

The solution involves determining the configuration and curvature of a flexible display to optimize the placement and representation of notifications within a viewable display region, using viewing angle and curvature compensation transformations to ensure clear visibility, even when the device is in a closed or partially open configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If notifications are displayed on a flexible display in a closed or partially open configuration, then the device maintains portability and compactness, but the notification becomes obscured or distorted reducing user visibility

Engineering Contradiction:
Improvedevice compactnessVSAvoidnotification visibility
Core Design Contradiction:
Volume of moving objectVSLoss of information

Solution Approach 1:

The system performs preliminary actions by detecting the flexible display configuration state before displaying notifications. The processor determines whether the display is in a closed, partially open, or fully open configuration, and proactively selects the appropriate notification display region and transformation parameters in advance, ensuring notifications are always displayed in the optimal location regardless of device state

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The notification display region and representation are made dynamic rather than static. The system continuously monitors flexible display configuration changes and dynamically adjusts the notification display parameters including position, size, shape, and orientation transformations. This allows the notification display to adapt in real-time to different device configurations, maintaining visibility and readability whether the device is closed, partially open, or fully open

Inventive Principle:
Principle #15Dynamics

2Length of moving object

If the flexible display is folded or curved to maintain portability, then the device remains compact for transport, but distortion occurs in the displayed notification content

Engineering Contradiction:
Improvedevice portabilityVSAvoidnotification display accuracy
Core Design Contradiction:
Length of moving objectVSManufacturing precision

Solution Approach 1:

The system changes display parameters including position, size, shape, and orientation of notification content based on the detected flexible display configuration. The processor applies transformation parameters that compensate for curvature and folding effects, adjusting the notification representation to maintain accurate and readable display regardless of the physical state of the flexible display

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The processor acts as an intermediary between the notification content and the flexible display surface. It calculates and applies transformation parameters that mediate the relationship between the flat notification content and the curved/folded display surface, ensuring accurate representation by compensating for geometric distortions introduced by the flexible display configuration

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If notifications are displayed on the visible portion of the flexible display, then user accessibility is improved, but the display area available for notifications is reduced when the device is closed

Engineering Contradiction:
Improveuser accessibilityVSAvoidnotification display area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The system utilizes multiple dimensions and spatial relationships to determine notification placement. By considering the three-dimensional configuration of the flexible display including curvature radius, fold angle, and visible surface geometry, the processor identifies optimal notification display regions that maximize both user accessibility and available display area, sometimes placing notifications on surfaces that appear curved or folded but remain visible to the user

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