Shared Front Frame for LCD TV Thickness Reduction

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional LCD-TVs have an inelegant appearance and increased thickness due to a double-layered edge structure, which is costly to manufacture, especially for ultra-large sized TVs, failing to meet market demands for thinner and lighter designs.

Innovation Solution

A display module and device design where the backlight module and display screen are directly fixed together by a shared front frame, eliminating the need for a metal outer frame, and using a back cover to secure components, thereby reducing weight, thickness, and production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a metal outer frame is used to cover the front frame, then the structural strength is improved, but the thickness and weight of the display device increase

Engineering Contradiction:

Improvestructural strengthVSAvoidthickness

Core Design Contradiction:

StrengthVSLength of stationary object

Solution Approach 1:

The patent combines the front frame and metal outer frame into a shared front frame structure. The front frame serves dual functions as both the structural support for the display screen and the outer frame covering, eliminating the need for separate metal outer frame layers at the edges.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shared front frame performs multiple functions simultaneously: it provides structural support for the display screen, acts as the outer frame covering, and serves as the mounting structure for the backlight module and display screen assembly.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If a metal outer frame is used to cover the front frame, then the structural strength is improved, but the weight of the display device increases

Engineering Contradiction:

Improvestructural strengthVSAvoidweight

Core Design Contradiction:

StrengthVSWeight of stationary object

Solution Approach 1:

The patent combines the front frame and metal outer frame into a shared front frame structure, eliminating redundant materials and reducing overall weight while maintaining structural integrity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shared front frame performs multiple functions simultaneously, reducing the total material required and thus the weight, while still providing necessary structural support.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If separate metal molds are made for each ultra-large sized LCD-TV, then the manufacturing precision is improved, but the manufacturing cost increases

Engineering Contradiction:

Improvemold precisionVSAvoidmanufacturing cost

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The shared front frame design allows a single mold to be used for producing front frames that can accommodate different sizes of display screens, including ultra-large sizes. This universal mold reduces the need for multiple specialized molds.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The front frame is designed as a modular structure that can be adapted to different display sizes through configuration changes rather than requiring completely different molds for each size category.

Inventive Principle:

Principle #1Segmentation
