Guide Frame Coupling for Thinner Display Devices

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing LCD devices require a middle frame to fix the decorative part, rear cover, and guide frame, leading to increased component count and complexity, making it difficult to match components from different manufacturers and hindering the development of thinner designs.

Innovation Solution

A display device design where the guide frame is directly coupled with the decorative part and rear cover, eliminating the need for a middle frame by using coupling units and fastening members that extend in different directions for secure assembly, allowing the guide frame to form the exterior of the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a middle frame is used to fix the decorative part, rear cover, and guide frame, then the components can be securely assembled, but the number of components increases and the device becomes thicker

Engineering Contradiction:

Improveassembly stabilityVSAvoidcomponent count

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the middle frame's functions into the guide frame by integrating coupling units directly into the guide frame structure. This allows the guide frame to simultaneously support the display panel and couple with both the decorative part and rear cover, eliminating the need for a separate middle frame while maintaining assembly stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The guide frame is designed with multi-functionality, serving as both the structural support for the display panel and the coupling mechanism for attaching the decorative part and rear cover. The coupling units embedded in the guide frame enable it to perform multiple functions that previously required a separate middle frame.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a middle frame is used to fix the decorative part, rear cover, and guide frame, then the components can be securely assembled, but the device thickness increases

Engineering Contradiction:

Improveassembly stabilityVSAvoiddevice thickness

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

By combining the middle frame's coupling functions into the guide frame, the patent eliminates the additional thickness that would be required for a separate middle frame structure. The guide frame directly couples with the decorative part and rear cover, reducing the overall device thickness while maintaining secure assembly.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If multiple coupling parts are distributed across different components, then secure coupling is achieved, but component matching becomes difficult

Engineering Contradiction:

Improvecoupling strengthVSAvoidcomponent compatibility

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The guide frame is designed with universal coupling units that can accommodate both the decorative part and rear cover attachments. This standardized coupling mechanism embedded in the guide frame simplifies component matching and assembly, making it easier to integrate components from different manufacturers while maintaining reliable coupling.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Discussed herein is a display device. In the display device, a guide frame that is a component of a display module is directly coupled with a decorative part by using a coupling unit formed on the guide frame, such that the number of components to be assembled can be reduced, and the device can be made lighter and thinner. In addition, the guide frame may be exposed to the outside to form the exterior of the device.
