Mobile Phone Film Attaching Device with Tilted Reinforced Glass Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone screen protector attachment methods using reinforced glass films often result in bubbles due to the self-adhesion properties of the films, making accurate alignment and complete adhesion difficult, leading to suboptimal attachment quality and user frustration.
Innovation Solution
A mobile phone film attaching device with a recessed area and a connector system that positions the reinforced glass film at a tilt, allowing for automatic adhesion and air discharge, eliminating the need for manual alignment and reducing bubble formation, featuring a holding space that matches the phone's shape and a connector with a release film for easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the reinforced glass film is placed horizontally on the mobile phone screen to ensure accurate alignment, then the alignment accuracy is improved, but bubbles are generated due to air trapped in the center area
Solution Approach 1:
The patent introduces a third dimension by tilting the reinforced glass film relative to the mobile phone screen during attachment. The film is positioned at an angle rather than parallel to the screen, allowing air to escape in the vertical direction while maintaining horizontal alignment accuracy through the guide structure.
Solution Approach 2:
The patent pre-positions the reinforced glass film in a tilted state within the attaching device before contact with the screen. The guide structure预先 establishes the correct alignment and tilt angle, so that when the film attaches, it automatically follows the predetermined path that prevents bubble formation.
2Object-generated harmful factors
If the reinforced glass film is attached from one end to the other in a tilted position to reduce bubbles, then bubble formation is reduced, but manual alignment becomes very difficult without assistant tools
Solution Approach 1:
The patent introduces a film attaching device as an intermediary tool between the operator and the reinforced glass film. This device incorporates a guide structure that automatically provides alignment and maintains the tilted position during attachment, eliminating the need for difficult manual alignment while preserving the bubble-reduction benefits.
Solution Approach 2:
The guide structure within the attaching device automatically performs the alignment function without requiring manual intervention. The reinforced glass film self-aligns within the guide structure and maintains the tilted position throughout the attachment process, making the operation simple and repeatable.
3Area of stationary object
If the reinforced glass film is completely adhered to the mobile phone screen to ensure full coverage, then coverage completeness is improved, but white edges occur due to insufficient adhesion at the edges
Solution Approach 1:
The tilted attachment approach introduces a vertical dimension to the attachment process. The film contacts the screen at one end first and gradually adheres upward at an angle, ensuring that the edge portions make proper contact with the screen surface while air escapes from underneath, preventing white edges while maintaining full coverage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device simplifies the attachment process, reduces manual effort, and ensures high-quality adhesion without bubbles, allowing consumers to easily attach the film without complex alignment, enhancing user experience and market competitiveness.
Implementation Method 1
Reinforced glass films are self-adhesive. With the self-adhesion property, when part of the reinforced glass film is adhered to the mobile phone screen, even if no external force is applied, the adhesion area will gradually extend outward under the influence of the tension and gravity of the material itself
Implementation Method 2
Under the gravity and self adhesion force of the reinforced glass film 100, the reinforced glass film 100 is attached from the already adhered end 101 gradually toward the other end

AI summary
A mobile phone film attaching device equipped with a reinforced glass film, including: a film attaching device main body, a connector and a reinforced glass film, a holding space, and a recess area. The holding space has a bottom surface to touch the surface of the mobile phone screen; among the relative two ends of the reinforced glass film, one end is protruded from or aligned to the bottom surface, the other end is not protruded from the bottom surface, so that, when the film attaching device main body covers the mobile phone, among the relative two ends of the reinforced glass film, the end protruding from or aligned to the bottom surface touches the mobile phone screen, a gap is maintained between the end not protruding from the bottom surface and the mobile phone screen.
