Bendable Display Support Frame With Segmented Structure and Limit Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bendable intelligent terminals face limitations due to a small display screen and short battery life, and their support structures, such as rotating bearings, restrict overall bending and occupy significant space, reducing the size of functional modules like the display screen or battery, thus limiting their functionality and competitiveness.
Innovation Solution
A support frame for a bendable display screen comprising a fixed part, a bendable part with multiple frame members having gaps for flexibility, and an end part with limiting members, allowing for integrated rigid support and flexible deformation, enabling larger bending angles and maintaining structural stability while accommodating components like batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotating bearing with sheet solid structure is used to connect support structures, then local bending of a small area is achieved, but integrated design of rigid support and flexible deformation cannot be achieved
Solution Approach 1:
The support frame is divided into multiple frame members (first frame members and second frame members) that are connected through gaps. This segmentation allows each member to maintain structural integrity while the collective assembly enables flexible bending deformation, resolving the contradiction between rigid support and flexible deformation.
Solution Approach 2:
The support frame transitions from a static sheet solid structure to a dynamic structure where frame members can relative move through gaps. This dynamic design enables the structure to adapt between rigid support state (when members are closely positioned) and flexible deformation state (when members move relative to each other during bending).
2Adaptability or versatility
If a rotating bearing structure is used for support, then bending function is achieved, but available internal space is reduced
Solution Approach 1:
The support frame uses thin frame members with gaps instead of bulky rotating bearings. This flexible shell-like structure achieves bending functionality while occupying minimal space, significantly increasing the available internal space for functional modules like display screens and batteries.
3Strength
If sheet solid structure is used for supporting and rotating shaft, then structural support is provided, but space occupation is large
Solution Approach 1:
The solid sheet structure is segmented into multiple thin frame members with gaps between them. This segmentation dramatically reduces the volume occupied by the support structure while maintaining structural support capability through the distributed framework of multiple members.
Solution Approach 2:
The support frame adopts a porous-like structure with gaps between frame members, transforming the solid sheet into a space-efficient framework. This porous design reduces material volume and space occupation while preserving structural support function through the geometric arrangement of members.

AI summary
A support frame for a bendable display screen includes: a fixed part; a bendable part connected with the fixed part; and an end part arranged at an end of the support frame. The bendable part includes a first bendable part and a second bendable part. The first bendable part includes a plurality of first frame members connected with one another, and the plurality of first frame members have a gap therebetween. The second bendable part is connected with the end part. Both the end part and the fixed part are provided with a limiting member.
