Solution Overview

Problem

Existing flat panel display devices, particularly LCDs, face limitations in minimizing thickness and enhancing design aesthetics due to the use of multiple casing components that inevitably increase thickness and border widths, making it difficult to achieve slim and innovative designs.

Innovation Solution

A display device design that includes a guide frame supporting the bottom edge of the display panel, an adhesive member coupling the panel and frame, and a set cover with a soft member that closely surrounds the panel, eliminating the need for a front and rear set cover, thereby reducing thickness and enhancing aesthetics through an innovative design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If multiple casing components (front case, rear case, front set cover, rear set cover) are used to support the display panel, then the structural stability is improved, but the thickness of the display device increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidthickness

Core Design Contradiction:

Stability of the object's compositionVSLength of stationary object

Solution Approach 1:

The patent combines multiple separate casing components (front case, rear case, front set cover, rear set cover) into a single integrated case structure. This unified case supports the display panel while eliminating the cumulative thickness of multiple separate components, thereby reducing overall device thickness while maintaining structural stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts and eliminates unnecessary intermediate components (front set cover and rear set cover) from the traditional multi-component structure. By removing these redundant elements that do not contribute essential functions, the design achieves thinner profile while preserving the core structural support function through the integrated case.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If front set cover and rear set cover are used to cover the top edge of the display panel, then the protection function is improved, but the border width increases and thickness increases

Engineering Contradiction:

Improveprotection functionVSAvoidborder width

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The protective function previously distributed across front set cover and rear set cover is merged into the integrated case structure. The single case provides continuous protection along the top edge of the display panel while eliminating the additional border width that would result from multiple overlapping components.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If traditional multi-component casing structure is used, then the manufacturing process is standardized, but the productivity decreases due to complex assembly

Engineering Contradiction:

Improvestandardized processVSAvoidassembly efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

By merging multiple casing components into a single integrated case, the patent reduces the number of assembly steps required. Instead of sequentially assembling front case, rear case, front set cover, and rear set cover, the integrated case can be installed as a single unit, significantly improving assembly efficiency and productivity while maintaining manufacturing standardization.

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If multiple separate casing components are used, then the design flexibility is maintained, but the device complexity increases

Engineering Contradiction:

Improvedesign flexibilityVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate casing components into a single integrated case, reducing device complexity by eliminating the need to manage, align, and assemble four separate components. The integrated design maintains adaptability through modular internal structure and standardized mounting interfaces, achieving simpler overall architecture without sacrificing design flexibility.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosed are a display device and a manufacturing method thereof, which do not use some of cases and set covers necessary for producing the display device and thus can minimize a thickness and enhance a sense of beauty with an innovative design. The display device includes a display panel, a guide frame, an adhesive member, a set cover, and a soft member. The set cover receives the guide frame, and surrounds a side of the display panel. The soft member is formed at the set cover, and closely contacted to the side of the display panel.
