Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional bonding method is used to bond display module and window, then the bonding process is simple, but bonding defects occur due to difficulty in aligning and adhering curved surfaces with precision
Solution Approach 1:
The bonding device divides the pressing function into multiple independent jigs (first jig for central area, second jigs for corner areas) that can be controlled separately. This segmentation allows precise independent control of pressing positions to accommodate the curved surfaces of the display module and window, thereby improving alignment precision without requiring an overly complex monolithic device structure.
Solution Approach 2:
The bonding device employs movable jigs that can be dynamically positioned and controlled to apply pressure at specific locations (central and corner areas) on the curved surfaces. The jigs are designed to move along predetermined paths to match the curvature, enabling precise alignment and bonding while maintaining a relatively simple overall device structure through dynamic adaptation rather than complex fixed geometry.
2Manufacturing precision
If multiple jigs are used to press curved surfaces precisely, then bonding precision is improved, but device complexity increases
Solution Approach 1:
Each jig in the bonding device is designed with multi-functionality to perform multiple operations. The first jig handles the central pressing operation, while the second jigs handle corner pressing operations. Each jig can both position itself and apply controlled pressure, combining positioning and bonding functions in single components. This reduces the need for separate positioning mechanisms and bonding mechanisms, thereby improving bonding precision while limiting the increase in overall device complexity.
3Manufacturing precision
If precise alignment of curved surfaces is achieved through complex jig positioning, then bonding quality improves, but manufacturing time increases
Solution Approach 1:
The bonding device is designed with jigs that are pre-configured with predetermined movement paths and pressing positions that match the curvature geometry of the display module and window. The first jig is pre-positioned for central area bonding, and the second jigs are pre-positioned for corner area bonding. This preliminary configuration eliminates the need for complex real-time alignment calculations and adjustments during the bonding process, thereby achieving high alignment accuracy while maintaining efficient manufacturing speed.
