Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bonding devices are unable to effectively bond flexible screens to irregular-shaped curved cover plates, leading to interference and inadequate attachment, especially when the cover plate has a flat area and arc hook areas that transition smoothly.
Innovation Solution
A bonding device with a bonding body that includes adsorption and expansion components, where the adsorption component uses vacuum adsorption to secure the flexible screen and the expansion component adjusts to match the shape of the cover plate, allowing for precise attachment and expansion to ensure full contact with the curved surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bonding device is used to bond flexible screens to irregular-shaped curved cover plates, then the bonding process is simple, but the bonding effect is poor and interference occurs during bonding
Solution Approach 1:
The bonding device is divided into multiple independent sub-adsorption components and sub-expansion components arranged in an array. Each component can independently adsorb and expand to adapt to the irregular shape of the cover plate, avoiding interference while maintaining effective bonding across the entire surface.
Solution Approach 2:
The bonding device incorporates expandable components that can dynamically adjust their size and shape. The expansion components transition from a compact state during insertion to an expanded state during bonding, allowing the device to adapt to the curved surface of the cover plate and eliminate interference issues.
2Adaptability or versatility
If the bonding device uses a fixed-size pressing surface, then the device structure is simple, but it cannot adapt to irregular-shaped curved cover plates
Solution Approach 1:
The pressing surface is made dynamic through expandable components that can change size. The expansion components are configured to expand after insertion, transforming the pressing surface from a small fixed size to a larger adaptive size that matches the irregular shape of the cover plate, enabling versatile adaptation without excessive complexity.
Solution Approach 2:
The expansion components are designed with a nested structure that allows them to be compact during insertion and then expand to their full size during bonding. This nesting principle enables the bonding device to adapt to irregular shapes while keeping the insertion profile small and manageable.
3Reliability
If the flexible screen is pressed onto the cover plate without vacuum adsorption, then the device structure is simpler, but the flexible screen cannot be securely held during bonding
Solution Approach 1:
The bonding device uses vacuum adsorption components that create a pressure differential to securely hold the flexible screen during bonding. The adsorption components are integrated with the expansion components, using pneumatic principles to provide reliable attachment stability without requiring separate complex holding mechanisms.
