Bonding Device for Curved Cover Plates with Irregular Shapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional attaching devices are unable to effectively attach flexible screens to 3D curved cover plates with irregular shapes, as they are designed for fixed curved surfaces and fail when the cover plate is bent inwardly.
Innovation Solution
A bonding device comprising a first and second attaching half with abutting walls and a driving component, which moves between closed and open positions to securely attach a flexible screen to both the flat and arc hook areas of a curved cover plate with an irregular shape, utilizing vacuum adsorption and a telescopic mechanism for precise alignment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional attaching device is used, then the attachment process is simple, but it cannot effectively attach flexible screens to 3D curved cover plates with irregular shapes
Solution Approach 1:
The attaching device is divided into a first attaching half and a second attaching half that can move relative to each other. Each half has abutting walls with different shapes (first/second curved walls for arc hook areas, first/second flat walls for flat area) that can independently attach to different regions of the irregular cover plate, enabling the device to adapt to complex geometries through modular segmentation
Solution Approach 2:
The attaching device incorporates a driving component that enables the first and second attaching halves to move relative to each other between closed and open positions. This dynamic capability allows the device to adjust its configuration to match the irregular shape of the cover plate, transitioning from a static to a dynamic structure that can adapt to various geometries
2Adaptability or versatility
If the cover plate is bent inwardly to create arc hook areas, then the display can show front and side surfaces, but conventional attaching devices fail to attach properly
Solution Approach 1:
Different regions of the abutting walls are designed with locally optimized shapes: the first and second curved walls are specifically shaped to match the arc hook areas, while the first and second flat walls match the flat area. This local quality optimization ensures that each part of the device contacts the cover plate with the appropriate geometry, maintaining high attachment reliability across all regions including the bent arc hook areas
Solution Approach 2:
The abutting walls are pre-designed with specific shapes that match the target cover plate geometry before the attachment process begins. The first curved wall and second curved wall are pre-formed to conform to the arc hook areas, and the flat walls are pre-formed for the flat area, ensuring that when the device closes onto the cover plate, proper contact is already established without requiring complex real-time adjustments
3Area of stationary object
If a single attaching half is used, then the device structure is simple, but it cannot attach both arc hook areas and flat area simultaneously
Solution Approach 1:
The attaching device is segmented into a first attaching half and a second attaching half, each equipped with abutting walls having different shapes. This segmentation allows each half to target specific regions (arc hook areas or flat area) of the cover plate, thereby expanding the total coverage area while keeping each individual component relatively simple in structure

AI summary
A bonding device for attaching a curved cover plate with an irregular shape to a flexible screen includes: a first attaching half having a first abutting wall, a second half, and a driving component. The first abutting wall includes a first curved wall and a first flat wall. The first curved wall matches with an inner surface of the arc hook area, and the first flat wall is smoothly connected to the first curved wall. The second attaching half has a second abutting wall. The second abutting wall includes a second curved wall and a second flat wall. The second curved wall matches with an inner surface of the arc hook area. The second flat wall is smoothly connected to the second curved wall. The driving component drives the first attaching half and the second attaching half to move relative to each other.
