Solution Overview

Problem

Current electronic devices with display screens face a trade-off between display area and portability, as larger display screens require larger hardware, reducing portability.

Innovation Solution

A foldable display apparatus featuring a flexible display screen and a bearer component that can unfold into multiple shapes, allowing the display area to be expanded while maintaining compactness for carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the display screen is enlarged to increase display area, then the display area is improved, but the hardware size must be enlarged which reduces portability

Engineering Contradiction:
Improvedisplay areaVSAvoidhardware size
Core Design Contradiction:
Area of moving objectVSLength of moving object

Solution Approach 1:

The bearer component is divided into multiple plane parts (first plane part, second plane part, third plane part) connected by bending parts, allowing the display structure to be segmented into foldable sections that can be collapsed for portability while maintaining large display area when unfolded

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bearer component transitions from a static rigid structure to a dynamic foldable structure with bending parts that can change between curved and plane states, enabling the device to adapt between large-screen display mode and compact portable mode

Inventive Principle:
Principle #15Dynamics

Solution Approach 3:

When the bearer component is folded, the third plane part is nested between the first and second plane parts, and the flexible display screen is folded accordingly, creating a compact nested configuration that maintains portability while preserving the large display area capability

Inventive Principle:
Principle #7Nested doll (Nesting)

2Length of moving object

If the bearer component is folded to improve portability, then the length is reduced to one third, but the display area is reduced

Engineering Contradiction:
ImprovelengthVSAvoiddisplay area
Core Design Contradiction:
Length of moving objectVSArea of moving object

Solution Approach 1:

Different parts of the flexible display screen have different functions: parts on the first and second plane parts are designed to be exposed and used for display in folded state, while parts on the third plane part are folded inward, creating local quality differences in display functionality across the screen

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

In the folded state, approximately two thirds of the flexible display screen area is exposed and can still be used for display, providing partial display functionality that satisfies basic viewing needs while achieving compact portability

Inventive Principle:
Principle #16Partial or excessive action
