Solution Overview

Problem

As display devices trend towards miniaturization and thinness, the use of glass back covers increases weight, costs, and degrades handling ability, necessitating a lighter and more rigid solution.

Innovation Solution

A display device design featuring a plastic back cover with an inner plate and reinforcing structures, such as connectors and a reinforcing bar, to enhance rigidity and facilitate a multi-display configuration while maintaining lightness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a glass back cover is used to secure rigidity, then rigidity is improved, but weight increases

Engineering Contradiction:

ImproverigidityVSAvoidweight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The back cover is divided into multiple plates (first plate, second plate, third plate) connected by connectors, creating a modular structure that achieves rigidity through geometric arrangement rather than material density, thereby reducing weight while maintaining structural strength

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The back cover uses a composite structure combining multiple plastic plates with connector elements, creating a lightweight alternative to solid glass while achieving comparable or superior rigidity through the distributed framework design

Inventive Principle:

Principle #40Composite materials

2Strength

If a glass back cover is used, then rigidity is improved, but handling ability degrades

Engineering Contradiction:

ImproverigidityVSAvoidhandling ability

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The segmented back cover structure with multiple plates and connectors creates a lighter overall weight that is easier to handle and install, while the distributed connector system provides multiple attachment points for easier assembly operations

Inventive Principle:

Principle #1Segmentation

3Strength

If a plastic back cover with reinforcing structures is used, then rigidity is improved, but device complexity increases

Engineering Contradiction:

ImproverigidityVSAvoidstructure complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The connectors serve dual functions by both joining the plates together to create rigidity and acting as reinforcing elements themselves, eliminating the need for separate reinforcing structures and reducing overall device complexity

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connector elements perform multiple functions simultaneously: structural joining, rigidity reinforcement, and potential heat dissipation pathways, thereby achieving enhanced rigidity without adding dedicated complex reinforcing components

Inventive Principle:

Principle #6Universality (Multi-functionality)
