Solution Overview

Problem

Recent display devices with increased screen size and reduced thickness face challenges in maintaining adequate strength, leading to potential deformation due to their own weight.

Innovation Solution

A display device configuration featuring a frame structure composed of extrusion molded members, including beams, pillars, and sub-pillars, coupled with an intermediate member to hold the display panel, ensuring strength while minimizing weight increase.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the screen size is increased and the thickness is reduced, then the display device achieves a larger display area and thinner profile, but the structural strength decreases and deformation occurs due to its own weight

Engineering Contradiction:

Improvescreen sizeVSAvoidstructural strength

Core Design Contradiction:

Area of moving objectVSStrength

Solution Approach 1:

The housing is divided into multiple extrusion molded members (beams and pillars) that are coupled together to form a frame structure. This segmentation allows each member to be optimized for strength while keeping the overall structure lightweight, resolving the contradiction between large screen size and adequate structural strength.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses extrusion molded members that combine material strength with optimized geometric cross-sections. These composite structural elements provide high strength-to-weight ratio, enabling the display device to maintain structural integrity while achieving reduced thickness and increased screen size.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If a single sheet metal housing is used to hold the display panel, then the manufacturing process is simple, but the weight increases significantly

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoiddevice weight

Core Design Contradiction:

Ease of manufactureVSWeight of moving object

Solution Approach 1:

Instead of using a single sheet metal housing, the structure is segmented into multiple extrusion molded members (beams and pillars) that are coupled together. This segmentation significantly reduces the overall weight while maintaining manufacturing feasibility through standardized extrusion processes and assembly operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces the traditional single-piece sheet metal mechanical structure with an assembled frame structure made of extrusion molded members. This substitution reduces weight while maintaining manufacturing simplicity through modular assembly of pre-fabricated components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
