Foldable Display Support Structure for Reduced Screen Creasing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with inward folding mechanisms often develop creases on the display screen, leading to a shorter service life, and there is a need for a mechanism that maintains a large display area while ensuring high portability and reduced crease formation.
Innovation Solution
A folding mechanism with symmetrical first and second screen supporting plates, housing bases, and a base portion, allowing for a flared structure in the folded state to minimize crease formation and accommodate the display module, while maintaining an unfolded state for a large display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display screen is folded inward to achieve compactness, then the portability is improved, but creases are formed on the display screen reducing its service life
Solution Approach 1:
The display screen is divided into a first display module and a second display module, with the first display module being foldable relative to the second display module. This segmentation allows the screen to be folded into a compact configuration for portability while the first and second modules can be positioned to minimize crease formation on the flexible display screen, thus resolving the contradiction between portability and service life.
2Volume of moving object
If the display screen is folded inward to reduce device size, then portability is improved, but the display area is reduced
Solution Approach 1:
The display screen is designed as a flexible display screen that can dynamically change its configuration between an unfolded state providing a large display area and a folded state providing a compact device size. The first display module can rotate relative to the second display module, enabling the device to adapt its form factor based on usage requirements, thus resolving the contradiction between display area and device size.
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 mechanism prolongs the service life of the display screen by minimizing crease formation and allows for a compact, portable electronic device design with a large display area in the unfolded state.
Implementation Method 1
The first screen supporting plate rotatably matches the first housing base, and the second screen supporting plate rotatably matches the second housing base. Both the first housing base and the second housing base are rotatably connected to the base portion.

AI summary
A folding mechanism, a support structure, and an electronic device are provided. The folding mechanism includes a first screen supporting plate, a second screen supporting plate, a first housing base rotatably matching the first screen supporting plate, a second housing base rotatably matching the second screen supporting plate, and a base portion. The first housing base and the second housing base are rotatably connected to a plurality of first rotation portions of the base portion in a one-to-one correspondence manner by means of respective second rotation portions.
