Solution Overview

Problem

Conventional multi-display devices face challenges in easily attaching and detaching display modules due to engagement portions being hidden, leading to difficulties in repair, replacement, and alignment, which increases installation time and complexity.

Innovation Solution

A mounting apparatus using an interlocked rotational engagement body with a magnetic member and bearing unit, facilitated by a rotation module, allows for easy attachment and detachment of display modules by magnetic force, with alignment ensured through an alignment unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If engagement members such as bolts and clamps are used to install display modules to the profile structure body in the rear, then the display modules can be securely mounted, but the engagement portions are not exposed on the front side making detachment and repair difficult

Engineering Contradiction:
Improvesecure mountingVSAvoiddetachment difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The engagement member is divided into a first engagement member extending from the front surface and a second engagement member extending from the rear surface. This segmentation allows the front engagement portion to be accessible for detachment while the rear engagement portion provides secure mounting, resolving the contradiction between secure mounting and ease of repair.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If the plurality of display modules are installed with almost no interval between them in a narrow bezel type configuration, then the display area is extended and visual information is improved, but there is structural limitation preventing coupling to the profile structure body in front of each display module

Engineering Contradiction:
Improvedisplay areaVSAvoidcoupling flexibility
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The engagement member extends in the thickness direction of the display module, utilizing the Z-dimension rather than requiring lateral space. This allows the narrow bezel configuration to be maintained while providing accessible engagement portions for coupling and detachment, resolving the contradiction between display area and coupling flexibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If coupling operation is performed in the rear of the display modules, then the display modules can be mounted, but the coupled state of the front surface cannot be determined requiring frequent checking during assembly

Engineering Contradiction:
Improvemounting capabilityVSAvoidalignment detection
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

A magnetic member is introduced as an intermediary between the engagement member and the display module. The magnetic member allows for easy detection of the coupled state through magnetic attraction, enabling front surface alignment verification without requiring frequent checking during assembly, thus resolving the contradiction between mounting capability and alignment detection.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If conventional installation structure is used, then display modules can be mounted, but detaching or attaching requires large amount of work time and has very high work difficulty

Engineering Contradiction:
Improvemounting stabilityVSAvoidinstallation efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The conventional mechanical fastening system using bolts and clamps is replaced with a magnetic field-based engagement system. The magnetic member provides secure mounting through magnetic attraction while allowing easy attachment and detachment by simply bringing the engagement member close to or removing it from the display module, dramatically improving installation efficiency while maintaining mounting stability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
