Display Stand with Rear Speaker Box for Stability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Thin flat panel displays have a center of gravity close to the display panel module, making them prone to falling, which necessitates a protruding stand that limits design flexibility.

Innovation Solution

A display device with a separately provided stand located on the lower rear side of the rear exterior panel, incorporating a speaker box with a built-in speaker, which shifts the center of gravity closer to the rear, preventing falling without the need for a forward-protruding stand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a stand protrudes forward from the front side exterior panel to prevent falling, then stability is improved, but design flexibility deteriorates

Engineering Contradiction:

ImprovestabilityVSAvoiddesign flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

Instead of placing the stand at the front side to prevent falling, the invention inverts the approach by placing the stand at the rear side lower portion of the display device. This reverse positioning achieves the same stability function while eliminating the design limitation caused by front-side protrusion.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The invention changes the spatial dimension of the stand placement from the front horizontal dimension to the rear vertical dimension. By positioning the stand at the rear side lower portion rather than protruding from the front, the solution utilizes a different spatial arrangement to achieve stability without compromising design flexibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If the stand is integrated with the rear side exterior panel, then device complexity is reduced, but center of gravity position deteriorates (moves away from lower rear side)

Engineering Contradiction:

Improvedevice complexityVSAvoidcenter of gravity position

Core Design Contradiction:

Device complexityVSWeight of moving object

Solution Approach 1:

The invention segments the stand function from the rear side exterior panel by providing the stand as a separate component. This segmentation allows the stand to be positioned independently at the lower rear side to optimize center of gravity, while the rear side exterior panel maintains its primary function without integrated stand structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The stand is designed as a separate component that serves multiple functions: providing structural support for stability and housing the speaker unit. This multi-functionality allows the stand to be positioned optimally for center of gravity while also integrating audio functionality, rather than being merely an structural attachment to the exterior panel.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A display device includes a panel module including a display cell; a front side exterior panel and a rear side exterior panel which sandwich the panel module therebetween from back and front; a driving circuit which drives the display cell; and a stand which is separately provided from the rear side exterior panel, includes a speaker box inside which a first speaker is built-in, and is located on a lower rear side of the rear side exterior panel when placing the panel module.
