Cover Window Mold With Stepped Pressurizing Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for processing cover windows often result in defects due to non-uniform pressurization, which can lead to suboptimal manufacturing efficiency and quality.
Innovation Solution
The use of a multi-mold apparatus with stepped thickness structures in the second and third molds ensures uniform pressure distribution across the processing area, reducing defects by matching the thickness differences in the molds to the pressurizing force applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single uniform mold structure is used for processing multiple cover windows, then the device complexity is reduced, but non-uniform pressurization occurs leading to processing defects
Solution Approach 1:
The mold structure incorporates different thicknesses at different locations (first thickness at the first pressurizing portion, second thickness thinner than the first at the second pressurizing portion) to provide localized pressurization characteristics that match the specific processing requirements of each cover window position, thereby achieving uniform pressurization across multiple cover windows
Solution Approach 2:
The mold is divided into multiple pressurizing portions (first pressurizing portion and second pressurizing portion) with different thicknesses, allowing each segment to independently control the pressurization force applied to corresponding cover windows, preventing defects caused by non-uniform pressurization
2Productivity
If multiple cover windows are processed simultaneously, then productivity increases, but the risk of processing defects increases due to non-uniform pressurization
Solution Approach 1:
The mold structure with varying thicknesses serves multiple functions simultaneously: it provides support for multiple cover windows, applies uniform pressurization across all positions, and prevents processing defects, thereby enabling high-quality simultaneous processing of multiple cover windows
Solution Approach 2:
By incorporating different thicknesses at different locations in the mold, each region of the mold is optimized for the specific pressurization needs of the cover windows at that position, ensuring that all cover windows receive appropriate pressurization force regardless of their location, thus maintaining high processing quality while increasing productivity

AI summary
An apparatus for processing cover windows includes a first mold including a first support a second support spaced apart from the first support, where the first support and second support are configured to hold processing targets; a second mold; and a third mold spaced apart from the second mold. The second mold includes a first pressurizing portion overlapping with the first support, having a first thickness, and a second pressurizing portion connected with the first pressurizing portion and configured to overlap with the first support, having a second thickness thinner than the first thickness. The third mold includes a third pressurizing portion overlapping with the second support, having a third thickness, and a fourth pressurizing portion connected with the third pressurizing portion and overlapping with the second support, having a fourth thickness thinner than the third thickness.
