Foldable Display Hinge Layout for Larger Screens at Constant Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices with flexible displays face challenges in expanding display size while maintaining a certain thickness and integrating components like cameras and sensors, and they struggle with combining in-folding and out-folding structures effectively.
Innovation Solution
The electronic device incorporates a foldable housing with a flexible display and a combination of in-folding and out-folding hinge structures, allowing the display to expand by unfolding multiple housings, while maintaining a constant thickness and integrating components like cameras and sensors without additional displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a foldable housing with multiple housings and connecting members is used to expand display size, then the display area increases, but the device complexity increases
Solution Approach 1:
The housing is divided into multiple separate housings (first housing, second housing, third housing) connected by foldable connecting members. This segmentation allows the display to be expanded across multiple housing surfaces while maintaining a manageable structure for each individual housing unit.
Solution Approach 2:
When the device is folded, the multiple housings are arranged in a nested configuration where the second and third housings are positioned within or adjacent to the first housing. This nesting approach maximizes the compact form factor when folded while enabling large display area when unfolded.
2Adaptability or versatility
If the flexible display is positioned on multiple housing surfaces to expand display size, then the display versatility increases, but the manufacturing precision requirements increase
Solution Approach 1:
The flexible display is designed to be positioned on multiple different housing surfaces (first surface, third surface, fifth surface), allowing the same display component to serve multiple functions and positions. This multi-functionality approach enables display versatility without requiring separate display components for each position.
Solution Approach 2:
Each housing surface that may hold the display is designed with specific local characteristics (surfaces spaced apart by predetermined lengths, specific orientations) to ensure proper display positioning and functionality. This local quality approach ensures that manufacturing precision requirements are met at each specific location while maintaining overall versatility.
3Length of moving object
If the second connecting member has a thickness corresponding to the predetermined length to maintain device thickness, then the portability improves, but the ease of manufacture decreases
Solution Approach 1:
The second connecting member is designed with a specific thickness parameter that corresponds to the predetermined length between housing surfaces. This parameter change ensures that when the device is folded, the overall thickness is maintained within acceptable limits, improving portability while the specific parameter value is chosen to balance manufacturing feasibility.
