Screen Film Positioning Fixture for Bubble-Free Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adhering protection films to electronic device screens are inaccurate and aesthetically flawed, often resulting in bubbles and dust, with a low success rate and frequent shifting during the process.
Innovation Solution
A film sticking device with a main body featuring a first film sticking part and a protruding film positioning component to fix the screen protection film, allowing precise alignment and attachment to the screen, and a second film sticking part for covering and securing the device, along with a connecting mechanism for easy handling and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual film sticking is used, then operation simplicity is maintained, but positioning accuracy and adherence quality deteriorate
Solution Approach 1:
The patent introduces a positioning component as an intermediary element between the film and the operational surface. This component features positioning structures that engage with corresponding features on the film, providing precise alignment without requiring complex automated systems. The mediator enables accurate film placement while maintaining relative operational simplicity.
Solution Approach 2:
The positioning component is pre-configured with positioning structures before the film sticking operation. These structures are designed in advance to match specific features on the film, allowing the film to be accurately positioned and adhered in a single operation. This preliminary preparation eliminates the need for complex real-time adjustment mechanisms during the sticking process.
2Stability of the object's composition
If manual film application is used, then device simplicity is maintained, but film stability during application deteriorates
Solution Approach 1:
The positioning component serves as a mediator that provides stable positioning for the film during the sticking operation. Its positioning structures engage with corresponding features on the film, preventing shifting and ensuring stability throughout the application process while maintaining ease of operation.
3Manufacturing precision
If automated positioning systems are implemented, then positioning precision improves, but device complexity and cost increase
Solution Approach 1:
Instead of implementing complex automated positioning systems, the patent uses a simple positioning component as an intermediary. This component provides precise film alignment through mechanical engagement with positioning structures, achieving high positioning precision without the complexity and cost of automated systems.
Solution Approach 2:
The positioning component and film are designed with complementary positioning structures that automatically align and engage with each other during the sticking operation. This self-aligning mechanism eliminates the need for complex external positioning systems, providing precise alignment through the inherent design of the components themselves.
