Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The continuous development of display devices has led to narrower borders, resulting in a smaller portion of the display panel under the front frame, making it prone to falling off and reducing stability, thereby increasing the risk of damage.

Innovation Solution

Incorporating a snap-fit connection with limiting elements, such as positioning pillars or screws, between the display panel and the plastic frame to secure the panel between the front frame and the backlight module, enhancing stability and preventing panel detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the border of the display device is narrowed, then the aesthetic appearance and modern design are improved, but the display panel becomes prone to falling off and the stability is reduced

Engineering Contradiction:

Improveborder widthVSAvoidpanel stability

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The securing mechanism is segmented into multiple components: limiting holes in the display panel, limiting elements (positioning pillars or screws) that pass through these holes, and the plastic frame with corresponding positioning structures. This segmentation allows the narrow border design to maintain stability through a distributed securing system rather than relying on a large border area alone.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Limiting elements act as intermediaries between the display panel and the plastic frame. These elements (positioning pillars or screws) pass through limiting holes in the display panel and engage with the plastic frame, creating a mechanical connection that secures the panel even when the border is narrow. The intermediary structures transfer and distribute the securing forces across multiple points.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the display panel is secured with traditional methods, then the structure is simple, but the panel is easy to fall off and damage risk increases

Engineering Contradiction:

Improvesecuring structure complexityVSAvoidpanel retention reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The securing mechanism uses a nested structure where limiting elements (positioning pillars or screws) pass through limiting holes in the display panel and insert into corresponding recesses or engage with the plastic frame. This nested arrangement creates a multi-layered securing system that enhances reliability while maintaining reasonable structural complexity. The limiting holes are nested within the panel, and the limiting elements are nested within these holes, creating a hierarchical securing mechanism.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A display device is provided. The display device includes a backlight module, a display panel, and a front frame. The backlight module includes a plastic frame. The display panel is attached on the plastic frame and is positioned at an emitting side of the backlight module. A limiting hole is defined in the display panel. The front frame engages with the display panel by a snap-fit connection and defines a first limiting element corresponding to the limiting hole. The first limiting element cooperates with the limiting hole to secure the display panel between the front frame and the plastic frame.
