Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable electronic devices experience reduced reliability and service life of the flexible screen due to pulling or squeezing during the unfolding and folding process.
Innovation Solution
A foldable apparatus with a mounting bracket, rotating bracket assembly, swing arm assembly, and transmission assembly that allows the rotating brackets to move away from the mounting bracket during folding, increasing the accommodation space and reducing stress on the flexible screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible screen is pulled or squeezed at the folding position during folding process, then the folding function can be achieved, but the reliability and service life of the flexible screen are reduced
Solution Approach 1:
The patent introduces a folding component as an intermediary element between the left and right housings. This folding component includes a folding member that can rotate relative to the housing, and a folding component holder that supports the flexible screen. The intermediary structure allows the housing to fold while the flexible screen is supported and protected, preventing direct pulling or squeezing forces from being applied to the screen during the folding process.
Solution Approach 2:
The patent divides the folding mechanism into separate functional segments: the folding component (with rotating folding member), the folding component holder (supporting the flexible screen), and the housing structure. This segmentation allows each component to perform its specific function independently - the folding member handles the folding motion while the holder protects the flexible screen, thereby preventing direct mechanical stress on the screen during folding.
2Reliability
If the accommodation space in folded state is increased, then the flexible screen is protected from squeezing, but the device complexity increases
Solution Approach 1:
The patent implements a nested structure where the folding component and folding component holder are integrated within the housing structure. The folding member rotates within the housing cavity, and the folding component holder is positioned to support the flexible screen during folding. This nesting arrangement creates sufficient accommodation space to protect the flexible screen from squeezing while minimizing the overall increase in device complexity by utilizing existing structural spaces.

AI summary
A foldable apparatus and an electronic device, wherein foldable apparatus includes a mounting bracket and a rotating bracket assembly. The rotating bracket assembly includes a first rotating bracket and a second rotating bracket arranged on two sides of the mounting bracket along a width direction of the mounting bracket. The first rotating bracket is rotatably connected to the mounting bracket by using a first rotating shaft. The second rotating bracket is rotatably connected to the mounting bracket by using a second rotating shaft. When the first rotating bracket and the second rotating bracket rotate toward each other, the first rotating shaft and the second rotating shaft move in a direction away from the mounting bracket along the width direction of the mounting bracket.
