Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Flexible display apparatuses are prone to defects such as dents when subjected to external pressures, due to their bending deformation capabilities.

Innovation Solution

A support assembly comprising at least one first support unit with a recessing portion and at least one second support unit with an embedding portion, allowing the assembly to switch between states to provide stable support and protection to the flexible display panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the flexible display panel is designed to be bendable and deformable, then the adaptability and versatility are improved, but the reliability deteriorates due to susceptibility to dents and defects under external pressure

Engineering Contradiction:

Improvebending deformation capabilityVSAvoidresistance to dents

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The support assembly employs a nested structure where the second support unit is embedded within the first support unit. The embedding portion of the second support unit fits into the recessing portion of the first support unit, creating a compact nested configuration that provides structural support while maintaining flexibility of the display panel.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The support assembly is divided into multiple independent support units (first support unit and second support unit) that can function separately or in combination. Each support unit is structurally independent with its own embedding or recessing portions, allowing modular support that adapts to different operational states of the flexible display panel.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If the support assembly uses an embedded configuration, then the device complexity is reduced, but the manufacturing precision requirement increases due to the need for precise embedding portions

Engineering Contradiction:

Improvestructural simplicityVSAvoidembedding portion precision

Core Design Contradiction:

Device complexityVSManufacturing precision

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A support assembly and a display apparatus are provided. The support assembly includes first and second support units. The first support unit includes a first recessing portion. The second support unit includes a first embedding portion. The first support unit includes first and second surfaces that are opposite to each other. The second support unit includes a third surface and a fourth surface that are opposite to each other. Operating states of the support assembly include a first state and a second state. In the first state, the first embedding portion is embedded in the first recessing portion. In the second state, the first surface and the third surface are disposed in a same horizontal plane, the first surface and the third surface abut against each other, and the second surface and the fourth surface are located at a same side of the support assembly.
