Screen Protector with Localized Thickness for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen protectors for mobile information terminals face challenges in easy attachment without bubbles and maintaining operability while ensuring engagement strength, often requiring professional installation and frequent replacement due to peeling issues.
Innovation Solution
A protector with a thin screen cover and thicker side parts, connected through slopes, that engages with the sides of the terminal, preventing bubble entry and peeling, while maintaining screen sensitivity and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protector is made thin to maintain screen operability, then screen touch sensitivity is improved, but engagement strength with the side face deteriorates
Solution Approach 1:
The protector applies different thicknesses to different regions: the screen cover area is kept thin (0.1-0.3mm) to maintain touch sensitivity, while the engaging part extending to the side face is made thick (0.5-1.0mm) to ensure strong engagement. This local differentiation resolves the contradiction between operational sensitivity and engagement strength.
2Strength
If the protector is made thick to ensure engagement strength, then engagement strength is improved, but screen touch sensitivity and terminal size deteriorate
Solution Approach 1:
The protector applies different thicknesses to different regions: the screen cover area is kept thin (0.1-0.3mm) to maintain touch sensitivity, while the engaging part extending to the side face is made thick (0.5-1.0mm) to ensure strong engagement. This local differentiation resolves the contradiction between operational sensitivity and engagement strength.
3Reliability
If a protection film is attached to the screen, then screen protection is improved, but attachment complexity and time consumption increase
Solution Approach 1:
The invention merges the screen cover and side face engagement functions into a single integrated protector structure. The engaging part extends from the screen cover to the side face, allowing simultaneous protection and secure attachment without requiring separate components or complex multi-step attachment processes.
Solution Approach 2:
The engaging part acts as an intermediary element that bridges the screen cover and the side face of the terminal. It provides a mechanical connection point that simplifies attachment by engaging with the side face opening, eliminating the need for precise positioning and bubble-free attachment required by traditional screen films.
4Reliability
If a protection film is attached to the screen, then screen protection is improved, but the risk of peeling and finger entrapment increases
Solution Approach 1:
The invention merges the screen cover and side face engagement functions into a single integrated protector structure. The engaging part extends from the screen cover to the side face, allowing simultaneous protection and secure attachment without requiring separate components or complex multi-step attachment processes.

AI summary
[Problem] Provided is a screen protector that can be easily mounted on a mobile information terminal and is able to favorably maintain the operability of the screen at the touch of the screen while ensuring engagement strength.[Solving Means] A protector configured to be mounted on a front face of a mobile information terminal includes a thin part configured to cover a screen of the mobile information terminal and a pair of thick parts disposed on upper and lower sides of the thin part and having a greater thickness than the thin part. The thin part includes a screen cover configured to cover the screen and a thin engaging part extending from the screen cover toward a side face of the mobile information terminal and configured to engage with the side face. The thick parts each include a thick engaging part connected to the thin engaging part and configured to engage with the side face.
