Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tiled displays face challenges in maintaining uniform seam width due to tolerances in support structure dimensions and misalignment of tiles, leading to visual artefacts and difficulties in servicing.

Innovation Solution

The use of adjustable support substructures that allow for movement of display tiles in a plane parallel to the nominal display plane, creating a gap between tiles that is larger than the nominal seam, facilitating easier access for maintenance and alignment.

1Ease of repair

If adjustable support substructures are used to facilitate maintenance access, then ease of repair is improved, but device complexity increases

Engineering Contradiction:

Improveaccessibility for maintenanceVSAvoidsupport structure complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The support structure is divided into modular support substructures, each independently adjustable. This segmentation allows maintenance personnel to access and adjust individual tiles without affecting the entire display wall, improving ease of repair while keeping each module relatively simple

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support substructures incorporate adjustable mechanisms that allow dynamic positioning of display tiles in the X and Y directions. This dynamic capability enables maintenance access by creating gaps between tiles, while the adjustability is built into standardized components rather than custom mechanisms

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If complex mechanical connections are used to align tiles, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:

Improvetile alignment precisionVSAvoidmechanical connection complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The support substructures are designed to automatically align adjacent display tiles through their mechanical interface geometry. The structures self-align during assembly without requiring complex external alignment mechanisms or tools, achieving precise alignment while maintaining simplicity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The support substructures act as intermediary elements between the display tiles and the mounting surface. They provide a standardized interface that simplifies the connection while ensuring precise alignment through their designed geometry, avoiding the need for complex direct tile-to-tile connections

Inventive Principle:

Principle #24Intermediary (Mediator)
