Solution Overview

Problem

Existing display devices lack a solution for accurately guiding and securely attaching a thin, flat display panel to a target attachment surface while maintaining a sleek appearance and ensuring the panel is not easily separated or coupled, which affects user focus on the screen and the device's overall aesthetic and functional integrity.

Innovation Solution

The display device employs a combination of coupling parts, including hooks and magnetic materials, along with a module cover and PCB cover, to securely attach the display panel to the target attachment surface in a parallel configuration, ensuring accurate positioning and easy detachment, while maintaining a slim profile and minimizing visible components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a thin, flat display panel is used to achieve a sleek appearance, then the device aesthetic and slim profile are improved, but the panel becomes difficult to securely attach and position accurately on a target surface

Engineering Contradiction:
Improveslim profileVSAvoidattachment security
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The coupling mechanism is divided into multiple discrete components: a first coupling part with a first hook, a second coupling part with a second hook, and magnetic coupling parts. This segmentation allows each component to perform its specific function (mechanical hooking, magnetic attraction, positioning) while collectively achieving secure attachment of the thin display panel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention combines multiple coupling mechanisms (mechanical hooks and magnetic attraction) into a single integrated attachment system. The first and second hooks provide mechanical interlocking, while the magnetic coupling parts provide additional attraction force and positioning, creating a hybrid coupling system that overcomes the limitations of using either mechanism alone.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If coupling parts are added to securely attach the display panel, then attachment security is improved, but the device complexity and visible components increase

Engineering Contradiction:
Improveattachment securityVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The coupling parts are designed to perform multiple functions simultaneously. The hooks provide both mechanical interlocking and positioning guidance, while the magnetic coupling parts provide both attraction force and alignment assistance. This multi-functionality reduces the need for separate components for each function, thereby reducing overall complexity.

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

Solution Approach 2:

The coupling parts act as intermediaries between the display panel and the mounting surface. Rather than directly attaching the thin panel to the surface, the coupling parts mediate the connection, providing mechanical hooks that interlock with corresponding features on the mounting surface, thereby simplifying the attachment process while maintaining security.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If magnetic coupling parts are used to attach the display panel, then ease of attachment and detachment is improved, but the positioning accuracy may be compromised

Engineering Contradiction:
Improveattachment easeVSAvoidpositioning accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The first and second hooks are designed to engage with corresponding features on the mounting surface before the magnetic coupling parts come into full effect. This preliminary mechanical interlocking establishes the correct position and orientation, ensuring positioning accuracy is achieved before the magnetic attraction provides the final secure attachment and easy detachment capability.

Inventive Principle:
Principle #10Preliminary action

AI summary

A display device includes a body including a display panel, a module cover positioned on a rear side of the display panel, and first and second coupling parts formed in a first position of the module cover and a second position spaced apart from the first position, and a target attachment surface placed in a first state in which the target attachment surface is coupled to the body and a second state in which the target attachment surface is separated from the body, and including third and fourth coupling parts positioned to face the first and second coupling parts in the first state, wherein the first coupling part and the third coupling part are coupled and the second coupling part and the fourth coupling part are coupled in the first state, and the body and the target attachment surface may be parallel to each other. Since the body is coupled to be parallel to the target attachment surface by a plurality of coupling parts, the body may be guided to an accurate position and a user may be able to be more focused on a display screen.
