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 and device longevity.
Innovation Solution
A protective bracket is designed for the bending region of a 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 flexible screen is used to achieve a large screen area on a small-sized electronic device, then the screen display effect is improved, but the flexible screen is prone to damage in the bending region
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 the bracket to adapt to the bending motion while maintaining protective strength.
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.
2Reliability
If a protective structure is added to protect the flexible screen, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The protective bracket is integrated with the hinge assembly, combining the protective function with the existing folding mechanism. This merging approach avoids adding a completely separate protective system, thereby limiting the increase in device complexity.
Solution Approach 2:
The protective bracket uses a flexible part made of thin, bendable material that can conform to the bending region. This thin-film approach provides protection without adding significant thickness or structural bulk, maintaining device simplicity.
3Strength
If a rigid protective structure is used, then the strength is improved, but the thickness of the device increases
Solution Approach 1:
The protective bracket applies different material properties to different regions: the flexible part uses thin, bendable material for the bending region, while the rigid part uses stronger material for structural support. This local differentiation provides strength where needed without uniformly increasing device thickness.
Solution Approach 2:
The protective bracket combines flexible and rigid materials in a composite structure. The flexible part provides conformability and thin-profile coverage, while the rigid part provides structural strength, achieving both protection and thinness through material composition.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The protective bracket effectively safeguards the flexible screen from wear and tear, maintaining a thin and lightweight design while ensuring reliable protection against bending-related damage.
Implementation Method 1
The flexible part is connected in the bending region of the flexible screen and can be bent along with bending of the flexible screen
Implementation Method 2
a part of the metal part is embedded in the flexible part, so that structural strength of the protective bracket can be improved
