Rollable Display Support Rod Structure for Low-Stress Screen Unfolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support members in rollable screen devices require the flexible screen to transmit force during unfolding or rolling, leading to potential damage due to excessive stress on the screen.
Innovation Solution
A support apparatus with rotatably connected first support rods, featuring guide bend portions that allow for independent movement and force transfer between rods, reducing the need for the flexible screen to bear the load during unfolding or rolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the flexible screen is fixedly connected to the support member to form a whole, then the support member and flexible screen can unfold or roll simultaneously, but the flexible screen is subject to greater force during the process and is prone to damages
Solution Approach 1:
The support member is divided into multiple independent support rods that are rotatably connected through guide bend portions. This segmentation allows each rod to move independently during unfolding and rolling, transferring the mechanical load from the flexible screen to the support rod structure, thereby reducing stress on the screen while maintaining stable support functionality.
2Ease of operation
If the support member relies on the flexible screen to transmit force during sliding and rolling, then simultaneous unfolding is achieved, but the flexible screen experiences excessive stress
Solution Approach 1:
The guide bend portions serve as intermediary structures that enable force transmission between adjacent support rods without requiring the flexible screen to bear the load. These guide bend portions transfer the unfolding force through the support rod connections, allowing simultaneous movement while protecting the flexible screen from excessive stress.
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 solution minimizes stress on the flexible screen, preventing damage by allowing the support apparatus to slide and roll without direct attachment, ensuring smooth operation and extended device lifespan.
Implementation Method 1
the first guide bend portion on a first side of one of the adjacent two first support rods rotatably abuts against the second guide bend portion on a second side of the other of the adjacent two first support rods

AI summary
A support apparatus, a housing provided with the support apparatus, and an electronic device provided with the housing. The support apparatus comprises a plurality of first support rods rotatably connected to each other in a first direction. Each of the first support rods comprises a first rod body, first folding guidance portions, and second folding guidance portions. The first rod body comprises two opposite sides in the first direction, and each side of the first rod body is provided with a first folding guidance portion and a second folding guidance portion. The first folding guidance portion and the second folding guidance portion on one side of one first support rod are rotatably respectively abutting against the second folding guidance portion and the first folding guidance portion on one side of another first support rod adjacent thereto. When two adjacent first support rods rotate relative to each other, the first folding guidance portion slidably abuts against the inner surface of the second folding guidance portion, so as to generate a force transmitted between the two first support rods, thereby enabling the support apparatus to move along a rolling path.
