Screen Protector Pressing Assembly for Crease-Free Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen protector sticking tools generate creases and blade lines on the screen protector plate, affecting subsequent use, and lack universality due to fixed scraper blade positions that do not adapt to different device and protector thicknesses.
Innovation Solution
A screen protector sticking method and tool with an adjustable scraper blade and a screen protector plate assembly that allows for 180° flipping and tight fitting, using a sliding cover with an oblique scraper blade and elastic member to adjust height, and a pull handle for seamless peeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen protector plate is bent from the middle to tear down the screen protector, then the screen protector can be stuck to the electronic device, but creases are generated on the screen protector plate
Solution Approach 1:
The screen protector is divided into a first screen protector portion and a second screen protector portion that can be separately stuck to the electronic device. This segmentation allows each portion to be applied without bending the entire plate, preventing crease formation while maintaining ease of operation.
2Adaptability or versatility
If the scraper blade height is fixed, then the structure is simple, but the tool cannot adapt to different electronic devices and screen protector plate thicknesses
Solution Approach 1:
The scraper blade height is made adjustable through a sliding structure that allows the blade to move vertically along the screen protector plate. This dynamic adjustment enables adaptation to different device and protector thicknesses while maintaining a relatively simple overall structure through straightforward mechanical guidance.
3Ease of operation
If the screen protector is torn down from the middle, then the sticking process is simplified, but blade lines are generated on the screen protector plate
Solution Approach 1:
By dividing the screen protector into separable portions that can be independently applied, the need to tear from the middle is eliminated. Each portion can be carefully positioned and adhered without creating blade lines or surface defects, thus maintaining both operational simplicity and surface quality.

AI summary
The present disclosure relates to a screen protector sticking method, a screen protector sticking tool, and a screen protector plate assembly. The screen protector sticking tool includes a main body piece, a front locating piece, a rear locating piece, and a pressing assembly. The pressing assembly includes a sliding cover, a scraper blade, and an elastic member. The sliding cover is slidably connected to the main body piece, and the scraper blade is rotatably connected to the sliding cover; the scraper blade is oblique relative to the sliding cover and gradually moves away from a first end in a direction from the sliding cover towards the main body piece; and the elastic member is arranged between the sliding cover and the scraper blade to adaptively adjust a height position of the scraper blade.
