Solution Overview
Problem
The installation of screen protectors on electronic devices, particularly using the wet application method, is challenging due to the need for precise alignment, avoidance of dust and bubbles, and requires skill, making it difficult for users without training to achieve flawless results.
Innovation Solution
A device with a support member, clamp mechanism, tack assembly, and roller assembly that securely holds the electronic device and bonds the screen protector, ensuring proper alignment, tacking, and liquid removal without manual squeegeeing, allowing any user to install screen protectors quickly and easily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If wet application adhesive is used to eliminate dust and bubbles, then installation quality is improved, but operation difficulty increases and requires extensive training
Solution Approach 1:
The patent introduces a water-based application liquid as an intermediary substance that facilitates the wet application process. This liquid acts as a mediator between the adhesive and the screen, enabling easy alignment and bubble removal while maintaining high installation quality. The intermediary liquid reduces the complexity of working with tacky adhesives directly.
Solution Approach 2:
The system enables self-alignment through the interaction between the water-based liquid and the adhesive layers. The liquid allows the screen protector to naturally settle into proper alignment without requiring skilled manual manipulation, making the process self-correcting and easier to perform correctly on first attempt.
2Measurement precision
If manual alignment is performed during wet application, then alignment precision can be achieved, but installation time increases and skill is required
Solution Approach 1:
The patent applies the water-based liquid to the adhesive layer before placing the screen protector, creating a preliminary prepared state that facilitates automatic alignment. This preliminary action of wetting the adhesive allows the components to self-align during placement, eliminating the need for time-consuming manual alignment adjustments and reducing the skill level required.
3Reliability
If excessive liquid remains between screen protector and screen, then bonding is incomplete, but removing liquid manually increases complexity and risk of contamination
Solution Approach 1:
The system incorporates a liquid extraction mechanism that automatically removes excess water-based liquid from between the screen protector and the screen. This extraction function separates the liquid removal task from the manual installation process, ensuring complete bonding without requiring the user to perform complex manual squeegeeing operations that could introduce contamination.
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 enables seamless, consistent, and effective installation of screen protectors on electronic devices, preventing misalignment, bubbles, and incomplete bonding, even for users without prior experience, by using a tack assembly to secure the protector and a roller assembly to remove excess liquid.
Implementation Method 1
a roller member moves across the screen protector to bond the screen protector to the electronic device and remove any excess liquid that may exist between the screen protector and the electronic device
Implementation Method 2
a tack member applies a force onto the screen protector which tacks the screen protector to the electronic device and prevents misalignment

AI summary
An apparatus and/or method for installing a screen protector on an electronic device, for example using a wet application process. The apparatus includes a support member for supporting the electronic device and a clamp mechanism for clamping the electronic device in a fixed position on the support member. A tack assembly is used to tack the screen protector to the electronic device. The tack assembly includes an actuator that, once actuated, causes a tack member to apply a force onto the screen protector which tacks the screen protector to the electronic device and prevents misalignment. Finally, a roller assembly is actuated so that a roller member moves across the screen protector to bond the screen protector to the electronic device and remove any excess liquid that may exist between the screen protector and the electronic device.
