Solution Overview

Problem

Ultra-thin display devices face challenges in minimizing thickness while maintaining functionality, especially when wall-mounted, due to spatial restrictions and the need for additional components, which increases volume and limits contact with the wall.

Innovation Solution

The design incorporates a display unit with minimal components for image output and an AV box, where the display unit and AV box exchange signals via wires or wirelessly, with a flexible cable configuration and modular structure to minimize thickness and allow close contact with the wall, and includes a metal sheet for structural support and a sealing member to prevent foreign substances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional components are added to the display device for receiving and outputting broadcasting signals, then the functionality and versatility of the device is improved, but the volume and thickness of the device increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidvolume
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The display device is divided into two independent parts: a display unit containing only essential components for image output, and an AV box containing additional components for signal reception and processing. This segmentation allows the display unit to remain thin and lightweight while the AV box can be positioned separately, thus maintaining functionality without increasing the display device's volume.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The additional components for broadcasting signal reception and processing are extracted from the display unit and placed in a separate AV box. This extraction removes the volume-increasing components from the display unit, allowing the display unit to achieve minimal thickness while the AV box handles the additional functional requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

2Length of stationary object

If the display device is designed to be ultra-thin for wall mounting, then the thickness is minimized, but the ability to contact the wall completely is reduced and spatial arrangement is restricted

Engineering Contradiction:
ImprovethicknessVSAvoidspatial arrangement
Core Design Contradiction:
Length of stationary objectVSEase of operation

Solution Approach 1:

By segmenting the display device into a thin display unit and a separate AV box, the display unit can be designed with minimal thickness for wall mounting, while the AV box provides the necessary spatial arrangement and component placement flexibility. The display unit can contact the wall completely without being constrained by bulky components.

Inventive Principle:
Principle #1Segmentation

3Length of stationary object

If components are concentrated in the display unit to maintain minimal thickness, then the thickness is reduced, but heat dissipation becomes more difficult

Engineering Contradiction:
ImprovethicknessVSAvoidheat dissipation
Core Design Contradiction:
Length of stationary objectVSTemperature

Solution Approach 1:

The segmentation of components into the display unit and separate AV box allows heat-generating components to be distributed across two separate locations. This distribution improves heat dissipation by reducing thermal concentration in the display unit, while still maintaining minimal thickness in the display unit itself.

Inventive Principle:
Principle #1Segmentation
