Foldable Structural Member With Buckle Locking for Stable Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with foldable screens cannot maintain a folding state and may automatically open after being folded.
Innovation Solution
A foldable structural member with a structural main body and a buckle assembly, comprising a first and second buckle piece, allows the display device to switch between unfolding, inward-folding, and outward-folding states, ensuring the display panel remains in a desired configuration through buckling engagement of the buckle pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is made foldable to enable inward or outward bending, then the adaptability and versatility of the display device are improved, but the structural stability deteriorates causing the device to cannot keep a folding state and may open automatically
Solution Approach 1:
The buckle assembly is pre-configured with buckle pieces positioned to engage at specific folding states. Before the device is folded, the buckle pieces are prepared in advance to automatically engage when the folding motion is completed, ensuring the device maintains its folded state without requiring additional stabilization actions afterward
Solution Approach 2:
The buckle assembly acts as an intermediary mechanism between the first and second main bodies. The buckle pieces serve as mediating elements that connect the two main bodies during folding, providing the necessary mechanical constraint to maintain the folded configuration and prevent automatic opening
2Stability of the object's composition
If a buckle assembly is added to maintain folding states, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The buckle assembly is segmented into multiple independent buckle pieces distributed at different positions on the first and second main bodies. This segmentation allows each buckle piece to independently engage and maintain folding states, providing stable locking without requiring a single complex buckling mechanism
Solution Approach 2:
The buckle pieces are designed to dynamically engage and disengage based on the folding state. During normal folding operations, the buckle pieces automatically engage to maintain the folded state, and can be easily released when needed, providing adaptive stability without permanent structural complexity

AI summary
A foldable structural member and a display device. The foldable structural member includes a structural main body including a first main body and a second main body distributed in a first direction, and a bending portion located between the first main body and the second main body, in which the foldable structural member is enabled to be switched between an unfolding state and a folding state by the bending portion, a buckle assembly, including a first buckle piece and a second buckle piece engaged with the first buckle piece, in which the first buckle piece is arranged on the first main body, and the second buckle piece is arranged on the second main body, in an inward-folding state or an outward-folding state, the first buckle piece is buckled with the second buckle piece to connect the first main body with the second main body.
