Problem
The manual application of screen protectors on electronic devices often results in air bubbles, misalignment, and improper adhesion, which can affect touch sensitivity and lead to peeling issues over time.
Innovation Solution
A screen protector installation tool with a pressing assembly that evenly presses the screen protector onto the device, a holding base for stable alignment, and a scrolling member for ensuring complete coverage, including curved edges, while preventing finger contact and using resilient elements for size tolerance and cushioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual application method is used, then operation simplicity is improved, but manufacturing precision deteriorates due to air bubbles and misalignment
Solution Approach 1:
The patent introduces a positioning film as an intermediary element between the screen protector and the screen. This positioning film includes positioning structures that engage with corresponding structures on the screen, ensuring precise alignment during the application process. The positioning film acts as a mediator that guides the screen protector into correct position, eliminating misalignment issues while maintaining manual application simplicity.
Solution Approach 2:
The patent applies preliminary action by pre-equipping the screen protector with a positioning film before the actual application. The positioning film is already attached to the screen protector in factory settings, with positioning structures pre-configured. This preliminary preparation ensures that when the user applies the screen protector manually, alignment is automatically achieved without requiring precise manual positioning skills.
2Device complexity
If manual application method is used, then device complexity is reduced, but reliability deteriorates due to peeling and adhesion issues
Solution Approach 1:
The patent performs preliminary cleaning action by equipping the screen protector with a cleaning film that is removed during application. This cleaning film pre-prepares the adhesive surface by removing contaminants, dust, and oils from the adhesive layer. By performing this cleaning action in advance (factory preparation), the adhesive reliability is significantly improved without requiring complex cleaning devices or procedures during manual application.
Solution Approach 2:
The patent segments the screen protector into multiple functional layers: a positioning film layer for alignment, a cleaning film layer for surface preparation, and the main protective layer. This segmentation allows each layer to perform its specific function optimally. The positioning film ensures proper placement, the cleaning film guarantees adhesive surface quality, and the main layer provides protection. This layered structure improves adhesion reliability while maintaining simple manual application.
3Manufacturing precision
If pressing assembly is added to eliminate air bubbles, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces a positioning film as an intermediary element between the screen protector and the screen, which includes positioning structures that engage with corresponding structures on the screen to ensure precise alignment during application.
Solution Approach 2:
The patent applies preliminary action by pre-equipping the screen protector with a positioning film before the actual application, with positioning structures pre-configured to ensure automatic alignment during manual application.
4Manufacturing precision
If positioning structures are added to align screen protector, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces a positioning film as an intermediary element between the screen protector and the screen, which includes positioning structures that engage with corresponding structures on the screen to ensure precise alignment during application.
Solution Approach 2:
The patent applies preliminary action by pre-equipping the screen protector with a positioning film before the actual application, with positioning structures pre-configured to ensure automatic alignment during manual application.
