Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen protective films face challenges with low film-sticking yield, difficulty for non-professionals to operate, and issues such as misalignment, bubbles, and dust accumulation during application.
Innovation Solution
A segmented film design with a layered structure comprising a surface protective film and a divided bottom film, equipped with alignment handles and a dust-sticking adhesive layer, allowing for segmental application and improved alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer release film covers the entire screen, then the film structure is simple, but the film-sticking yield is low and alignment is difficult
Solution Approach 1:
The bottom film is divided into multiple independent segments (first bottom film segment, second bottom film segment, etc.) that can be applied separately to different regions of the screen. This segmentation allows each segment to be aligned and adhered independently, improving overall film-sticking yield while maintaining structural simplicity through modular design
2Ease of operation
If the release film is torn at one time, then the operation is simple, but misalignment and bubbles occur frequently
Solution Approach 1:
The film is segmented into multiple applicability regions with corresponding segments that can be applied independently. This allows users to apply each segment separately with proper alignment, then combine them, reducing misalignment and bubble issues while keeping the operation simple through clear regional division
Solution Approach 2:
Alignment marks are provided in advance on the film segments to guide proper positioning before application. This preliminary alignment guidance ensures precise framing is achieved easily by users without requiring professional skills
3Device complexity
If a single-layer structure is used, then the film structure is simple, but dust and bubbles are prone to occur
Solution Approach 1:
The bottom film is divided into multiple segments that can be applied separately, reducing the surface area exposed to dust during application. Each segment can be handled and positioned carefully to minimize bubble formation, while the segmented structure itself helps prevent dust accumulation between layers
Solution Approach 2:
A dust-sticking adhesive layer is introduced as an intermediary between the release layer and the actual use layer. This intermediate layer specifically targets and adheres to dust particles, preventing them from causing defects in the final film application while maintaining the overall simple layered structure

AI summary
The utility model discloses a segmented film, including a surface protective film and a bottom film which are sequentially arranged from top to bottom, where the surface protective film includes substrate for the surface protective films and adhesive layers, the bottom film includes release layers and a dust-sticking adhesive layer, and the bottom film is divided into several parts. According to the layered and segmented structure of the bottom film of the utility model, the film sticking method can be completed easily by untrained personnel; furthermore, the technical effect of avoiding the adsorption of dust and cilia in the air and removing residual dust on a screen by sticking can be achieved, dust and bubbles are avoided, and the yield is very high.
