Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable display devices face issues with durability under external loads and increased bezel size due to incomplete folding and space constraints, which affect their performance and design.
Innovation Solution
A display device with a folding hinge unit comprising panel support plates, hinge links, and brackets that allow for eccentric rotation and central axis movement, ensuring complete closure and sufficient space for panel bending, thereby enhancing durability and reducing bezel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-link hinges or two-axis folding hinges are used, then the hinge mechanism can enable folding, but the folding section cannot be completely closed resulting in poor durability to external load
Solution Approach 1:
The hinge mechanism is divided into multiple components: first and second hinge links, first and second hinge shafts, and first and second hinge brackets. This segmentation allows each component to perform a specific function, enabling the folding section to be completely closed while maintaining structural integrity and durability under external loads.
Solution Approach 2:
The hinge mechanism employs movable connections between hinge links and brackets through hinge shafts, allowing dynamic adjustment during folding operations. This dynamic structure enables complete closure of the folding section while accommodating external loads, improving both closure completeness and durability.
2Area of stationary object
If conventional hinge mechanisms are used to secure panel bending space, then the panel can be bent, but the bezel size increases
Solution Approach 1:
The hinge mechanism utilizes three-dimensional spatial arrangement with hinge links and brackets positioned at different levels and angles. This dimensional optimization allows the panel bending space to be efficiently utilized within a compact footprint, reducing the bezel size while maintaining sufficient space for panel bending.
3Reliability
If the folding section is completely closed to improve durability, then external load resistance increases, but the device complexity increases
Solution Approach 1:
Multiple hinge components (hinge links, hinge shafts, hinge brackets) are merged into an integrated assembly where the first and second hinge links are coupled together, and the hinge brackets are respectively connected to the first and second frames. This merging achieves complete closure for improved durability while consolidating the structure to manage complexity.
