Solution Overview

Problem

The challenge is to provide a stable and space-efficient solution for mounting multimedia devices and home appliances on walls while minimizing the number of protruding furniture and electronics, especially addressing the safety concerns for children and maintaining a neat appearance.

Innovation Solution

A smart wall system with a frame structure that includes a mounting cell, a display device, a driving roller, a screen, and a motor for vertical movement, utilizing timing gears and belts for stable screen operation, and a metal mesh for support, allowing the screen to cover devices when not in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If multimedia devices and home appliances are mounted on the wall, then the number of protruding furniture is reduced and appearance is improved, but the screen becomes unstable and difficult to control

Engineering Contradiction:
ImproveappearanceVSAvoidscreen stability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

A fabric screen is introduced as an intermediary element that covers the multimedia devices when not in use, creating a neat appearance while allowing the devices to function normally. The fabric screen acts as a mediator between the need for aesthetic appearance and the functional requirements of the mounted devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The frame structure is divided into multiple mounting cells that can independently hold different devices. The screen is segmented to pass through specific cells while covering others, allowing selective exposure of devices based on usage needs.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the screen is wound around the driving roller, then vertical movement is achieved, but the screen may slip or deform

Engineering Contradiction:
Improvevertical movementVSAvoidscreen control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A timing belt is introduced as an intermediary component between the driving roller and the screen. The timing belt with its toothed structure engages with the driving roller's teeth, providing positive engagement that prevents slipping while allowing smooth vertical movement of the screen.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The surface of the driving roller is coated with silicone or rubber material to change its friction characteristics. This parameter change in surface properties enhances the grip on the timing belt, ensuring reliable power transmission without slippage.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple devices are mounted in the living room, then functionality is improved, but safety risks increase for children

Engineering Contradiction:
Improvedevice functionalityVSAvoidsafety risks
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The fabric screen is extracted as a separate safety element that can cover potentially hazardous devices when not in use. This allows children-safe environments by hiding protruding devices while maintaining full functionality when needed.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of manufacture

If the frame structure is made deformable for easy installation, then ease of manufacture is improved, but structural strength may be compromised

Engineering Contradiction:
Improveframe assemblyVSAvoidframe rigidity
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The frame structure incorporates movable connections that allow the frame to be easily assembled and disassembled, yet maintain rigidity when installed. The dynamic nature of the connections enables easy manufacture while preserving structural strength during operation.

Inventive Principle:
Principle #15Dynamics

AI summary

A smart wall comprises: a frame structure comprising a mounting cell; a display device installed in the mounting cell; a driving roller provided above the mounting cell; a screen which is wound around the driving roller and comprises a first lower side portion located at the front side of the display device and a second lower side portion located at the rear side of the display device; and a motor for moving the screen wound around the driving roller, to thereby enable the screen, which covers the front surface of the display device, to receive the force of the motor without slipping, to thus be stably moved upward or downward.
