Solution Overview

Problem

Existing display devices lack versatility in mounting options, as they are either fixed to a stand or wall-mounted, limiting user flexibility and durability in handling.

Innovation Solution

A display device design featuring a hinge mechanism that allows the second housing to rotate from a standing state to a wall-mounted state, using a cylindrical hinge bar and a spring-loaded system for easy conversion, along with a through bolt and locking bracket for secure coupling, enabling flexible mounting without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a display device is fixed to a stand or wall-mounted, then mounting stability is improved, but user flexibility and adaptability are worsened

Engineering Contradiction:
Improvemounting stabilityVSAvoiduser flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The hinge mechanism enables the display device to dynamically transition between different mounting states (standing and wall-mounted), allowing the device to adapt its configuration based on user needs while maintaining secure connection throughout the transformation process

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hinge structure provides multi-functionality by enabling the display device to serve multiple mounting purposes (stand mode and wall-mounted mode) with a single integrated mechanism, eliminating the need for separate mounting solutions

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a hinge mechanism is added for state switching, then adaptability is improved, but device complexity is worsened

Engineering Contradiction:
Improvemounting option flexibilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hinge mechanism is divided into distinct functional segments (first housing, second housing, hinge connection) that can independently perform specific functions while working together as an integrated system, simplifying the overall design and manufacturing process

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a spring-loaded system is used for easy conversion, then ease of operation is improved, but device complexity is worsened

Engineering Contradiction:
Improvestate switching easeVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The spring-loaded hinge mechanism is designed to automatically provide the necessary force for state transitions, allowing the device to assist its own operation without requiring external tools or significant user effort, while the spring mechanism itself remains a simple, integrated component

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design enhances user flexibility by allowing easy switching between standing and wall-mounted states, reducing the risk of damage during handling and providing a secure, tool-free mounting solution.

Implementation Method 1

The inserted part may be separated from the insertion hole as a spring inserted into the second part contracts, when the first state changes to the second state

Methodology Applied
Scientific EffectSpring elasticity: Spring

AI summary

A display device is disclosed. The display device of the present invention includes: a display panel; a back cover provided to the rear side of the display panel; a first housing provided to at least part of the rear side of the back cover; a second housing, at least part of which contacts the first housing, the second housing having a main board and a power supply mounted therein; and a hinge for coupling the first housing and the second housing, wherein the second housing changes from at least one of a first state in which the second housing is extended in a direction perpendicular to the first housing and a second state in which at least one side of the second housing is extended in parallel with the rear side of the first housing to the other state, according to rotation of the hinge. Accordingly, the display device can easily switch between a standing type and a wall-mounted type by coupling the first housing and the second housing using a hinge.
