Curved Pad Cleaning Display Cover Windows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing processes for display devices fail to effectively clean curved portions of cover windows, leading to inadequate cleaning and increased cleaning time.
Innovation Solution
An apparatus and method featuring a pad with curvature matching the cover window's curvature, combined with a microfiber and a pushing driver, which moves the pad to contact the cover window, improving cleaning efficiency and reducing cleaning time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flat pad is used to clean the cover window, then the cleaning process is simple, but the curved portions of the cover window cannot be properly cleaned
Solution Approach 1:
The pad is designed with a curved surface that matches the curvature of the cover window. This curvature allows the pad to conform to and properly clean the curved portions of the cover window, resolving the issue of inadequate cleaning in curved areas while maintaining a relatively simple pad structure.
2Manufacturing precision
If a custom-shaped pad matching the cover window curvature is used, then cleaning efficacy in curved areas is improved, but the cleaning time increases
Solution Approach 1:
The curved pad design enables comprehensive cleaning of all curved areas in a single pass, eliminating the need for multiple cleaning operations or adjustments, thereby reducing overall cleaning time while improving cleaning quality.
Solution Approach 2:
The pad is designed to simultaneously clean multiple curved areas of the cover window with a single structure, making it a multi-functional cleaning tool that improves efficiency and reduces the total cleaning time required.
