Segmented Top Cover Fixing Protrusions for Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large size display apparatuses with divisible sub-chassis suffer from reduced bonding strength and assembly quality due to gaps between sub-chassis, which compromises the structural integrity and performance.
Innovation Solution
A display apparatus design featuring a top cover composed of multiple sub-covers that engage with fixing protrusions on a receiving container, preventing gaps and enhancing bonding strength between sub-covers through a narrow bezel structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single unitary cover is used, then manufacturing simplicity is maintained, but bonding strength and structural integrity deteriorate in large size display apparatuses
Solution Approach 1:
The top cover is divided into multiple sub-covers (first sub-cover, second sub-cover, third sub-cover, fourth sub-cover) that can be separately manufactured and assembled. Each sub-cover is coupled to the receiving container through fixing protrusions, allowing the large display apparatus to achieve sufficient bonding strength while maintaining manufacturing feasibility through modular construction.
2Adaptability or versatility
If multiple sub-chassis are used to accommodate large size displays, then adaptability to large screens is improved, but gaps occur between sub-chassis causing deterioration of bonding strength and assembly quality
Solution Approach 1:
The top cover is segmented into multiple sub-covers (first, second, third, and fourth sub-covers) that correspond to different regions of the large display apparatus. Each sub-cover is equipped with fixing holes that engage with fixing protrusions on the receiving container, ensuring precise positioning and eliminating gaps between adjacent sub-covers while maintaining adaptability to large size displays.
Solution Approach 2:
Fixing protrusions are strategically positioned at specific locations (first, second, third, and fourth positions) on the receiving container to correspond with fixing holes in each sub-cover. This localized fixing approach ensures that each sub-cover is securely attached at critical points, preventing gaps and improving overall assembly quality without requiring a completely different structure.

AI summary
A display apparatus includes a display unit which displays an image, a receiving container which accommodates the display unit, and a top cover which comprises a plurality of sub-covers to cover an edge of the display unit and is coupled to the receiving container. The receiving container comprises a fixing protrusion corresponding to a position that two sub-covers of the sub-covers overlap with each other, and each of the two sub-covers comprises a fixing hole coupled to the fixing protrusion.
