Solution Overview

Problem

There is a need to develop a support portion for flexible display devices that can firmly support the display module while minimizing the bezel region and enhancing the connection between link bars and support bars.

Innovation Solution

A display device design featuring a support plate, support bars, link bars, and guide rails that are integrated into the display module's structure to provide stable support and reduce bezel area, with link bars connected to opposite sides of the support bars and guide rails inserted into binding grooves for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the support portion structure is simplified, then the device complexity is reduced, but the firmness of support and connection between link bars and support bars deteriorates

Engineering Contradiction:
Improvesupport portion structureVSAvoidfirmness of support
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The guide rails are nested within the link bars, with the guide rails positioned inside the link bar structures. This nesting arrangement allows the guide rails to be integrated into the existing link bar framework without adding external complexity, while still providing the necessary guidance and support functions. The guide rails are located at positions where they can effectively guide the movement of the display module while maintaining a compact overall structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The guide rails extend in directions that are not simply parallel to the link bars, utilizing additional spatial dimensions for their arrangement. Specifically, the guide rails are positioned to extend in directions that provide multi-dimensional guidance, allowing the display module to move smoothly along complex paths while maintaining structural integrity. This dimensional approach enables better support firmness without proportionally increasing structural complexity.

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

2Area of stationary object

If the bezel region is reduced, then the display area is increased, but the structural support and connection stability deteriorate

Engineering Contradiction:
Improvebezel regionVSAvoidstructural support
Core Design Contradiction:
Area of stationary objectVSStrength

Solution Approach 1:

By nesting the guide rails within the link bar structures, the design eliminates the need for additional external support components that would increase the bezel width. The guide rails are integrated into the link bars themselves, allowing the support function to be maintained within the existing structural envelope, thereby minimizing the bezel region while preserving structural strength.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The link bars serve multiple functions simultaneously: they provide structural support, enable movement guidance through the guide rails, and maintain connection between different parts of the display module. This multi-functionality allows the same structural elements to perform both support and guidance roles, reducing the need for separate components that would increase the bezel width.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If link bars are firmly connected to support bars, then the connection stability is improved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveconnection stabilityVSAvoidmanufacturing difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The guide rails are nested within the link bars, creating an integrated structure where the guide rails and link bars form a unified assembly. This nesting arrangement simplifies the connection between link bars and support bars by eliminating the need for separate connection mechanisms, as the guide rails themselves provide the necessary guidance and connection functions within the existing structural framework.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The guide rails are positioned and oriented in specific three-dimensional configurations that facilitate easier manufacturing. By arranging the guide rails in directions that align with natural manufacturing processes and utilizing spatial positioning that simplifies assembly, the design achieves stable connections without proportionally increasing manufacturing complexity.

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