Solution Overview

Problem

The sizes of the hinge mechanism and the flexible display panel body do not match before and after folding, causing the hinge to squeeze or pull the display panel body.

Innovation Solution

A flexible display panel with a hinge mechanism comprising a fixing bracket, a first movement mechanism, and a second movement mechanism, allowing the first and second supports to move away from or close to the fixing bracket, adjusting the radius of curvature to match the flexible panel's size with the hinge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the hinge mechanism size is fixed, then the structure is simple, but the flexible display panel body cannot match the hinge size before and after folding, causing squeezing or pulling

Engineering Contradiction:

Improvesize matching between hinge and flexible display panelVSAvoidhinge mechanism structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hinge mechanism employs dynamic adjustment through two movement mechanisms that can change the distance between supports and the fixing bracket based on the flexible display panel's bending state. This allows the hinge to adapt its effective size to match the panel dimensions in both folded and unfolded states, eliminating squeezing or pulling while maintaining structural integrity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The hinge mechanism changes the spatial parameter (distance between supports and fixing bracket) according to the bending state of the flexible display panel. By adjusting this parameter dynamically, the hinge mechanism achieves size matching with the panel in different configurations without requiring complex redesign.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the hinge mechanism adjusts its size to match the flexible display panel, then the structural integrity is maintained, but the mechanism becomes more complex

Engineering Contradiction:

Improvestructural integrity during foldingVSAvoidmovement mechanisms

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The hinge mechanism is segmented into multiple independent movement mechanisms (first and second movement mechanisms) that can operate separately. Each mechanism adjusts its support independently based on the panel's bending state, allowing the system to achieve reliable size matching while keeping each individual mechanism relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixing bracket serves as an intermediary element that connects both movement mechanisms and provides a reference point for adjustment. This intermediary structure enables coordinated adjustment of both supports without requiring direct complex interaction between the mechanisms themselves, simplifying the overall design.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A flexible display panel and an electronic device are provided. The electronic device includes a flexible display panel. The flexible display panel includes a main body of the flexible display panel, a first support part, a second support part, and a hinge. When a flexible part of the main body of the flexible display panel is in a bent state, the first support part and the second support part are both close to or far from a fixing bracket to make a size of the flexible part match a size of the hinge, and to avoid the hinge from squeezing or pulling the main body of the flexible display panel.
