Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display module coupling structures result in thick modules due to perpendicular connector orientations, leading to gaps between screens, especially under temperature changes or external forces, and lack of coupling between modules.
Innovation Solution
A display device with a frame that includes first and second connection members, utilizing magnets for magnetic attraction between display modules, and a horizontal connector structure to minimize gaps and thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If connectors are coupled perpendicularly to the rear surface of the display module, then the connector structure can be simplified, but the module thickness increases
Solution Approach 1:
The patent changes the connector coupling direction from perpendicular (vertical dimension) to horizontal, coupling connectors in the horizontal direction between adjacent display modules. This dimensional change reduces module thickness while maintaining structural simplicity through the horizontal arrangement of first and second connectors on opposite sides of adjacent modules.
2Device complexity
If display modules are coupled to a set frame without inter-module coupling structures, then the overall structure is simplified, but gaps occur between screens
Solution Approach 1:
The patent merges the coupling functions by having display modules coupled to the set frame while simultaneously enabling direct coupling between adjacent display modules through horizontally arranged connectors. This combined approach ensures both screen continuity and structural simplicity.
Solution Approach 2:
The patent introduces planar fluidity through the first connection member, allowing display modules to move freely in the horizontal direction. This dynamic capability enables modules to self-adjust and maintain tight coupling with adjacent modules, preventing gaps while keeping the coupling structure simple.
3Ease of manufacture
If conventional coupling structures are used, then manufacturing is straightforward, but gaps increase under temperature changes or external forces
Solution Approach 1:
The first connection member provides planar fluidity that allows display modules to dynamically adjust their positions in response to temperature changes or external forces. This dynamic adjustment capability maintains precise screen coupling without complicating the manufacturing process.
Solution Approach 2:
The patent changes the coupling parameters by arranging connectors horizontally and providing planar fluidity, enabling the system to adapt to environmental parameter changes (temperature, external forces) while maintaining manufacturing simplicity through straightforward connector designs.
