Film Laminator With Hinged Plate For Cell Phone Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing film lamination methods for portable electronic devices, such as cell phones, face challenges with alignment, bubble formation, and the inability to ensure high-quality lamination, especially when using manual methods or complex and costly roller facilities, which are limited to flexible thin films.
Innovation Solution
A film laminator for cell phones featuring a cell phone fixing plate with a through hole and position limiting plates, a hinged film laminating plate, and an exhaust hole, designed to maintain even stress and precise alignment, allowing for effective lamination of hard thin films like glass or sapphire films without bubbles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual film lamination is used, then operation flexibility is maintained, but film alignment precision and lamination quality deteriorate
Solution Approach 1:
The patent uses transparent construction materials that allow visual observation and alignment verification during the lamination process, enabling operators to see through the plate to ensure precise film positioning while maintaining operational flexibility
Solution Approach 2:
The patent replaces complex mechanical alignment systems with a simple hinged plate mechanism combined with positioning holes, achieving precise alignment through geometric constraints rather than complex mechanical adjustments
2Manufacturing precision
If roller facilities are used for film lamination, then lamination quality improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent employs a simple, inexpensive hinged plate structure that can be easily manufactured and replaced if needed, eliminating the need for costly roller facilities while achieving comparable lamination quality through proper technique and plate design
Solution Approach 2:
The patent divides the lamination function into separate components: the fixing plate for substrate positioning, the hinged laminating plate for film application, and positioning holes for alignment, allowing each component to be simple while collectively achieving high lamination quality
3Strength
If hard thin films are laminated, then screen protection effectiveness improves, but lamination difficulty and bubble formation increase
Solution Approach 1:
The patent uses a hinged plate that can be dynamically positioned and pressed with controlled force, allowing the operator to adapt the pressing action to the specific properties of hard thin films, ensuring proper adhesion without causing bubbles or damage
Solution Approach 2:
The transparent hinged plate serves as an intermediary tool that distributes pressure evenly across the hard thin film during lamination, preventing localized stress points that could cause bubbles while ensuring uniform adhesion to the screen

AI summary
According to the utility model, there is provided a film laminator for cell phones, useful for film lamination on a surface of a cell phone, including: a cell phone fixing plate, on which a through hole for receiving the cell phone is established, and a top surface of which is a horizontal face; with at least one position limiting plate for abutting the cell phone within the through hole being also fixed on the top surface. The film laminator for cell phones further includes: a film laminating plate for fixing a cell phone film; one end of which is hinged to the cell phone fixing plate, and the other end of which is movable freely so that the film laminating plate is bonded with the top surface of the cell phone fixing plate. With respect to the film laminator for cell phones according to the utility model, because the position limiting plate is provided on the cell phone fixing plate, the surface of the cell phone to which a film is to be attached can handily be kept in flush with the top surface of the cell phone fixing plate. Upon film lamination, the film laminating plate can contact with the top surface of the cell phone fixing plate and the surface of the cell phone to which a film is to be attached at the same time, so that the stress that is laid on it in the course of film lamination is very even, and a good effect of film lamination is obtained.
