Curved Display Shield Cover Hook Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Curved display apparatuses face limitations due to minute differences in curvatures between display panels and accommodation members, leading to lifting phenomena in component coupling, which affects assemblability and appearance quality.
Innovation Solution
A display apparatus design featuring a display panel with a curved surface, a bottom cover with a bent side wall, a top cover with hook parts that engage with the shield cover, and a shield cover with coupling parts, ensuring uniform thickness and improved coupling properties by alternating hook and coupling parts along the display panel's long sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coupling structures are used in curved display apparatuses, then assembly is simplified, but lifting phenomena occur due to minute curvature differences between components
Solution Approach 1:
The coupling structure is divided into multiple segments: the side wall part of the bottom cover, the shield cover with its planar and bent parts, and the top cover with hook parts. This segmentation allows each component to independently accommodate curvature variations while maintaining overall coupling integrity, preventing lifting phenomena between components with slightly different curvatures.
Solution Approach 2:
Different parts of the coupling structure have different geometric properties tailored to their specific functions. The side wall part has a specific curvature designed to match the bottom cover, while the shield cover's planar part provides a flat mounting surface for the PCB. This local optimization of geometric properties allows each component to maintain its required curvature characteristics without causing lifting phenomena.
2Adaptability or versatility
If components are coupled with different curvatures, then assembly flexibility is improved, but lifting phenomena occur affecting appearance quality
Solution Approach 1:
The coupling structure utilizes multiple spatial dimensions to accommodate curvature differences. The side wall part extends vertically from the bottom cover, the shield cover provides a horizontal mounting plane, and the top cover's hook parts engage from above. This multi-dimensional arrangement allows components with different curvatures to be coupled without compromising appearance quality, as the coupling occurs across multiple spatial dimensions rather than requiring perfect curvature matching in a single plane.
3Shape
If uniform thickness is maintained in curved components, then manufacturing complexity increases, but appearance quality is improved
Solution Approach 1:
The design maintains uniform thickness as a key parameter throughout the curved components (bottom cover, top cover, shield cover). By consistently controlling the thickness parameter across all curved parts, the invention achieves uniform appearance quality without requiring complex variable thickness profiles. This parameter control approach simplifies manufacturing while ensuring aesthetic consistency across the curved display apparatus.
