Foldable Device Hinge Dustproof Fiber Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable electronic devices face issues with foreign matter infiltration through gaps in the hinge module, leading to potential malfunctions and display defects.
Innovation Solution
A fiber structure is deployed around the hinge module to prevent and reduce foreign matter infiltration, utilizing movable fibers and a base for fixation, which can deform to fill gaps and block external particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gap is maintained between the hinge module and housing for smooth operation, then the hinge module can fold or unfold smoothly, but foreign matter may infiltrate into the device through the gap
Solution Approach 1:
A fiber structure is introduced as an intermediary element between the hinge module and housing. This fiber structure fills the gap when the device is folded, preventing foreign matter infiltration, while allowing the hinge module to maintain smooth folding operations through the use of flexible materials that accommodate movement.
Solution Approach 2:
The fiber structure acts as a flexible barrier that can deform with the hinge module's movement. This flexible structure maintains the gap necessary for smooth operation while providing dustproof protection when folded, resolving the contradiction between operational smoothness and foreign matter prevention.
2Device complexity
If foreign matter infiltrates through the gap, then the device structure remains simple, but the hinge module may malfunction or the display may be damaged
Solution Approach 1:
The fiber structure serves as a simple intermediary component that provides reliable protection against foreign matter infiltration. This relatively simple addition prevents hinge module malfunction and display damage without significantly increasing overall device complexity.
Solution Approach 2:
The flexible fiber structure provides an effective barrier against foreign matter while maintaining structural simplicity. This thin, flexible layer protects the hinge module and display from contamination and damage without adding substantial complexity to the device architecture.
