Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

High-definition and large-sized display apparatuses appear smaller due to perimeter coverage by front covers, increasing manufacturing costs and assembly complexity.

Innovation Solution

A display apparatus design featuring a front panel securely supported by frames with stepped ends to prevent misalignment and warping, eliminating the need for a separate covering member, thus enhancing appearance and simplifying assembly while reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a separate front cover is used to support the front panel, then the front panel is securely supported, but the display screen appears smaller and manufacturing cost increases

Engineering Contradiction:

Improvefront panel supportVSAvoiddisplay screen area

Core Design Contradiction:

StrengthVSArea of stationary object

Solution Approach 1:

The patent merges the support function and the covering function into a single integrated frame structure. The frame directly supports the front panel at its perimeter while also serving as the external covering member, eliminating the need for a separate front cover and maximizing the visible display area.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The frame is designed to perform multiple functions simultaneously: it provides structural support for the front panel, serves as the external protective covering, and defines the overall appearance of the display apparatus. This multi-functionality resolves the contradiction by eliminating redundant components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If a separate front cover is used to support the front panel, then the front panel is securely supported, but manufacturing cost and assembly complexity increase

Engineering Contradiction:

Improvefront panel supportVSAvoidassembly complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

By combining the support function and covering function into a single frame structure, the patent reduces the number of components that need to be assembled. The frame is directly coupled to the front panel in one operation, simplifying the assembly process and reducing manufacturing complexity.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of manufacture

If frame ends are flat without steps, then assembly is simpler, but misalignment occurs under external force

Engineering Contradiction:

Improveframe assemblyVSAvoidframe alignment

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The stepped portions are pre-formed on the frame ends during manufacturing, creating built-in alignment features that guide the coupling of adjacent frames. This preliminary preparation ensures proper alignment under external forces without complicating the assembly process, as the steps naturally guide the frames into correct positioning.

AI summary

A display apparatus is provided. A frame is fixed and supported at the rear of a front panel forming the front portion of the display apparatus, and a separate bracket member is not mounted on the edges of the front panel. Thus, the front exterior of the display apparatus is neatly finished, and the display screen looks bigger than it actually is.
