Solution Overview

Problem

Conventional tiled display devices face challenges in precise assembly and disassembly due to the weight and size of large display panels, leading to visible seams and prolonged assembly/disassembly times, especially when used as temporary installations.

Innovation Solution

A magnetic coupling system with a first and second coupling unit, featuring a plug-socket relationship, where magnets are used to facilitate easy attachment and detachment of display panels, eliminating the need for screws and allowing for precise alignment without additional alignment apparatuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If display panels are tiled together to form large-sized display devices, then the display size is increased, but the gap between panels becomes visible and seams are perceived by viewers

Engineering Contradiction:
Improvedisplay sizeVSAvoidpanel alignment precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The coupling unit is divided into a first coupling unit attached to the display panel and a second coupling unit attached to the plate, allowing independent positioning and alignment of each segment to achieve precise overall alignment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling units act as intermediary components between the display panel and the plate, providing alignment features that ensure precise positioning while accommodating the large size of the panels

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If mechanical coupling elements such as screws are used to attach display panels, then the attachment strength is increased, but the assembly and disassembly time is significantly prolonged

Engineering Contradiction:
Improveattachment strengthVSAvoidassembly and disassembly time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The traditional screw-based mechanical coupling system is replaced with a magnetic coupling system where magnetic attraction forces provide sufficient attachment strength while allowing rapid assembly and disassembly through simple approach and separation movements

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

Solution Approach 2:

The coupling mechanism transitions from a static screw-locked state to a dynamic magnetic attraction state, allowing the display panel to be quickly attached by bringing the coupling units together and equally quickly detached by separating them

Inventive Principle:
Principle #15Dynamics

3Productivity

If the size of each display panel is increased to reduce the number of panels needed, then the complexity of precise positioning by workers is increased due to weight and size

Engineering Contradiction:
Improvenumber of panelsVSAvoidpositioning ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The coupling units incorporate self-aligning features that automatically guide the display panel into the correct position during attachment, eliminating the need for workers to manually precise-position heavy panels

Inventive Principle:
Principle #25Self-service
