Elastic Tile Positioning for Uniform Tiled Display Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tiled displays face challenges in maintaining precise alignment due to tolerances in support structures, leading to varying seam widths and visual artifacts, with existing solutions often requiring complex mechanical connections or being time-consuming to install.
Innovation Solution
A positioning device with elastic material and pin-and-opening combinations is used to link and align tiles, allowing for elastic deformation and minimal relative position changes, while fastening means like rubber fasteners accommodate displacements to compensate for tolerances, ensuring consistent seam width without complex hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex mechanical connections are used to align tiles, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The patent changes the physical state of the positioning device from rigid to elastic, allowing it to deform and adapt to tolerance variations in the support structure. This elastic deformation capability enables precise tile alignment without requiring complex mechanical adjustment mechanisms, thus improving alignment precision while maintaining simple device structure.
2Stability of the object's composition
If rigid positioning devices are used, then structural stability is improved, but adaptability to tolerance variations worsens
Solution Approach 1:
The positioning device is designed with elastic material properties that allow it to change its physical state from rigid to flexible under load. This enables the device to adapt to support structure tolerance variations through elastic deformation, while maintaining sufficient structural stability to ensure precise tile positioning when installed.
3Ease of operation
If adjustable mechanical bases are used, then alignment flexibility is improved, but installation time increases
Solution Approach 1:
The elastic positioning device automatically adapts to the support structure's tolerance variations through its own elastic deformation when tiles are installed. This self-adjusting mechanism eliminates the need for manual adjustment operations, providing alignment flexibility while significantly reducing installation time compared to adjustable mechanical bases that require operator intervention.

AI summary
A positioning device and a fastening means are described to fix the relative position of two or more adjacent tiles on a tiled display and to provide alignment. Fixing the relative position of two adjacent display tiles will facilitate the alignment of tiles in tiled displays where the seam between tiles will be as regular as possible, thereby avoiding the introduction of misalignments and their associated visual artefacts. According to an aspect of the present invention, there is provided a positioning device with allows linkage of it to at least two tiles of a tiled display. The display tiles are often rectangular in shape and the positioning device is then located at a corner of the tile. The positioning device can also be attached to a support structure to make a tiled display.
