Integrated Folding Hinge Structure for Lower-Cost Display Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding devices for bendable flexible display screens have complex manufacturing processes and high production costs due to numerous components, such as support plates and connecting members that require assembly through riveting or screwing.
Innovation Solution
A folding device with a side support member featuring embedded inserts, a rotating assembly, and a linkage assembly that allows for synchronous folding or unfolding of side support members, reducing the need for complex assembly and lowering production costs by using integrally moulded plastic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional support members with multiple connecting members are used, then the structural strength is sufficient, but the manufacturing process becomes complex and production costs increase
Solution Approach 1:
The patent combines multiple separate connecting members into a single integrated connecting member that performs multiple connection functions. This single component connects the side support plate to both the middle support member and the rotating assembly, eliminating the need for separate rivets or screws and simplifying the manufacturing process while maintaining structural strength
Solution Approach 2:
The connecting member is designed with multi-functionality, serving as both a structural connector and a rotational joint component. It provides both mechanical support and enables the folding motion, reducing the total number of components needed and simplifying assembly procedures
2Stability of the object's composition
If multiple separate components are used for the side support member, then the structural integrity is maintained, but the assembling process becomes cumbersome
Solution Approach 1:
The side support member is designed as an integrated component where the support plate and connecting members are formed as a single piece or pre-assembled unit. This integration maintains structural integrity while significantly reducing the number of assembly steps required during device manufacturing
3Reliability
If traditional riveted or screwed connections are used, then the connection reliability is sufficient, but the production cost increases
Solution Approach 1:
The connecting member integrates multiple connection functions into a single component that can be manufactured as one piece using processes like injection molding or stamping. This eliminates the need for separate fasteners and their associated assembly operations, reducing production costs while maintaining connection reliability through optimized structural design

AI summary
A folding device, a folding housing provided with the folding device, and an electronic device are provided. The folding device includes a support assembly, comprising a side support member on each of two opposite sides of the folding device; a rotating assembly, comprising a rotating member on each of two opposite sides of the folding device and a connecting member on each of two opposite sides of the folding device; and a linkage assembly, comprising a linkage member on each of two opposite sides of the folding device. The connecting member is rotatable to drive the rotating member and the linkage member to rotate, and rotations of the rotating member and the linkage member can drive the side support member to move, such that the two side support members on the two opposite sides of the folding device are configured to be synchronously folded or synchronously unfolded to each other.
