Solution Overview

Problem

Conventional display apparatuses have thick bezels and limited aesthetic appeal due to the structural constraints of the front and rear chassis, which also hinder the reduction of the display's overall thickness.

Innovation Solution

The display apparatus incorporates a middle mold that couples the diffuser plate in front of the light source module, with bonding members to secure the liquid crystal panel and optical sheets, and a fastening member system to assemble the rear, middle, and front chassis, allowing for a reduced bezel size and thinner profile.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional front and rear chassis structures are used, then structural support and assembly are ensured, but bezel size increases and aesthetic appeal decreases

Engineering Contradiction:
Improvebezel sizeVSAvoidchassis structure complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The chassis structure is divided into three separate components: front chassis, rear chassis, and middle mold. This segmentation allows each component to be optimized independently for its specific function while enabling thinner overall bezel dimensions through precise spatial arrangement of the segmented parts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The middle mold acts as an intermediary component between the front and rear chassis, providing structural support and alignment features. This intermediary element enables the front and rear chassis to be positioned closer together, reducing bezel thickness without compromising structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Shape

If thick bezel structure is used, then structural strength and assembly stability are ensured, but display area ratio decreases and aesthetic impression deteriorates

Engineering Contradiction:
Improvedisplay area ratioVSAvoidstructural strength
Core Design Contradiction:
ShapeVSStrength

Solution Approach 1:

Instead of uniformly thickening the entire bezel structure, the patent applies structural reinforcement locally at critical positions. The middle mold incorporates localized support features and the fastening holes are strategically positioned to provide strength only where needed, allowing thinner bezel dimensions in other areas.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The chassis components utilize composite material construction combining different materials with complementary properties. This allows optimization of both structural strength and dimensional precision, enabling thinner bezel designs that maintain adequate structural integrity through material composition rather than increased thickness.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If integrated chassis design is used, then assembly simplicity is ensured, but maintenance and part replacement become difficult

Engineering Contradiction:
Improveassembly simplicityVSAvoidmaintenance accessibility
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The display device is segmented into modular chassis components (front chassis, rear chassis, middle mold) that can be independently assembled and disassembled. This modular segmentation maintains assembly simplicity through standardized interfaces while enabling easy maintenance and part replacement by allowing access to internal components through the separated chassis structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The chassis design incorporates dynamic assembly capabilities with reversible fastening mechanisms. The fastening holes and associated fastening members allow the chassis components to be easily assembled during manufacturing and readily disassembled for maintenance, transforming a static integrated structure into a dynamically configurable modular system.

Inventive Principle:
Principle #15Dynamics
