Foldable Screen Protective Bracket for Bending Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible screens are prone to damage in the bending region due to frequent bending, affecting user experience.
Innovation Solution
A protective bracket is designed for the bending region of the flexible screen, comprising a flexible part and metal parts that are embedded in the main bodies, allowing the bracket to bend with the screen while enhancing structural strength and reducing thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a foldable structure is used to achieve large screen area on small device, then screen area is improved, but the flexible screen in bending region is prone to damage
Solution Approach 1:
The protective bracket is divided into a flexible part and a rigid part, with the flexible part covering the bending region and the rigid part providing structural support. This segmentation allows different regions to perform different functions, protecting the flexible screen while maintaining foldability.
Solution Approach 2:
The protective bracket acts as an intermediary component between the flexible screen and the external environment. It transfers and distributes mechanical stresses away from the flexible screen during bending, preventing direct damage to the screen while allowing the foldable structure to function.
2Reliability
If a protective bracket is added to protect the flexible screen, then reliability is improved, but device complexity increases
Solution Approach 1:
The protective bracket is integrated with the flexible screen and main body structure, merging multiple functions into a single component system. The bracket serves both as a protective element and as part of the overall structural framework, reducing the need for separate protective components.
Solution Approach 2:
The protective bracket uses a flexible part made of thin, bendable material that can conform to the bending region of the flexible screen. This thin-film approach provides protection without adding significant thickness or rigidity, maintaining the foldable characteristics while enhancing durability.
3Strength
If metal parts are embedded in the flexible part to improve structural strength, then strength is improved, but manufacturing complexity increases
Solution Approach 1:
The protective bracket combines flexible material with metal reinforcement parts to create a composite structure. The flexible part provides bendability and screen coverage, while the embedded metal parts provide structural strength and rigidity. This composite approach leverages the advantages of both material types to achieve both protection and durability.
Solution Approach 2:
The metal parts are embedded within or attached to the flexible part, creating a nested structure where the reinforcement elements are integrated into the protective bracket. This nesting allows the metal components to be positioned precisely where strength is needed without complicating the overall manufacturing process excessively.
