Cover Window Jig with Exhausting Portion for Printing Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jigs for cover windows in mobile devices fail to ensure uniformity and reliability of functional layers formed through printing processes, leading to potential defects and reduced durability.
Innovation Solution
A jig system comprising a lower jig with a mounting portion and an exhausting portion, and an upper jig with a cover unit and sidewall portion, where the side surface of the mounting portion is aligned with the side surface of the cover unit, forming a space for airflow and allowing for efficient collection of printing solutions and contaminants, thereby enhancing layer uniformity and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional printing process is performed on the cover window, then functional layers can be formed, but layer uniformity is poor and defects occur
Solution Approach 1:
The patent introduces a jig as an intermediary device between the printing process and the cover window. The jig includes a lower jig with a mounting portion and an upper jig with a cover unit that defines a printing space. This controlled intermediary environment ensures uniform layer formation by preventing printing solution from escaping and contacting the side surfaces of the cover window, thereby improving both layer uniformity and reducing defects.
2Productivity
If the cover window side surfaces are exposed to printing solution, then the printing process can be completed, but durability is reduced due to contaminants
Solution Approach 1:
The patent extracts or removes the harmful exposure of cover window side surfaces to printing solution by introducing the jig structure. The cover unit of the upper jig and mounting portion of the lower jig create a closed printing space that isolates the side surfaces from the printing solution, allowing the printing process to proceed efficiently while protecting the side surfaces from contamination that would reduce durability.
3Device complexity
If no enclosing structure is used during printing, then the printing process is simple, but printing solutions and contaminants are not collected effectively
Solution Approach 1:
The patent segments the printing system into distinct components: a lower jig with mounting portion and an upper jig with cover unit. This segmentation creates a defined printing space that effectively contains and collects printing solutions and contaminants while maintaining relative structural simplicity. The modular segmented design achieves effective solution collection without excessive complexity.

AI summary
A jig for a cover window may include a lower jig and an upper jig on the lower jig. The lower jig may include a mounting portion, on which a cover window is configured to be disposed, and an exhausting portion adjacent to the mounting portion. The upper jig may include a cover unit, in which an opening exposing the mounting portion is defined, and a sidewall portion, coupled to the cover unit and enclosing the lower jig. The cover unit may be spaced apart from and overlapped with the exhausting portion.
