Automobile Screen Protector Pasting Device with Positioning Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen protector pasting devices for automobiles are complex, making it difficult for non-professionals to accurately apply screen protectors without bubbles and ensuring proper alignment, as they obscure the screen and require additional adhesives.
Innovation Solution
A simple, hollow rectangular screen protector pasting assisting device with asymmetric handles and positioning protrusions that securely fix the screen protector by its corners, reducing bubble formation and eliminating the need for adhesive tape, while allowing clear observation during application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional screen protector pasting assisting device uses a frame panel to frame the screen protector, then the screen protector can be positioned within a well-limited position range, but the structure becomes complicated and it is not easy to observe air bubbles generated during the pasting process
Solution Approach 1:
The patent extracts the essential positioning function from the complex frame panel structure and implements it through simple positioning protrusions that extend from the bottom of the frame body. These protrusions directly engage with corresponding features on the screen protector, providing accurate positioning without requiring a complex framing mechanism. This simplifies the overall device structure while maintaining positioning accuracy.
Solution Approach 2:
The patent makes the frame body transparent or translucent, allowing users to clearly observe the screen protector and any air bubbles during the pasting process. This optical property change enables visual monitoring of the pasting quality without compromising the structural integrity or positioning functionality of the device.
2Manufacturing precision
If a conventional screen protector pasting assisting device uses a panel to cover the screen, then positioning is improved, but observation of air bubbles during pasting becomes difficult
Solution Approach 1:
The frame body is designed to be transparent or translucent, enabling users to visually detect air bubbles and monitor the pasting process in real-time. This optical transparency resolves the contradiction by allowing both accurate positioning (through the positioning protrusions) and easy observation of defects simultaneously.
3Extent of automation
If fully automatic film pasting devices are used, then automation is improved, but the structure becomes complicated and use becomes inconvenient for non-professional persons
Solution Approach 1:
The device enables users to easily perform the pasting operation themselves through simple positioning protrusions and a user-friendly frame structure. The positioning protrusions automatically guide the screen protector into the correct position, providing a form of self-alignment that eliminates the need for complex automated positioning systems while still achieving accurate results for non-professional users.
4Reliability
If conventional devices require adhesive tape for fixing the screen protector, then positioning is secured, but the structure and operation become more complicated
Solution Approach 1:
The patent extracts the fixing function from external adhesive tapes and integrates it directly into the device structure through positioning protrusions that extend from the frame body bottom. These protrusions mechanically engage with corresponding features on the screen protector, providing reliable fixation without requiring additional adhesive materials or complex application procedures.
