Sealing Member for Foldable Display Hinge Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable communication devices with foldable or rollable displays face issues of noise and damage due to friction between their rigid outer structures, which can allow foreign bodies to contaminate internal components when moving or rotating.
Innovation Solution
Incorporating sealing members, such as elastic materials like rubber or silicone, between the hinge cover and the housing structures to prevent friction and foreign body ingress, ensuring the integrity of internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid outer structures are coupled together to be movable or rotatable, then portability and screen size are improved, but friction and noise occur between the structures
Solution Approach 1:
A sealing member is introduced as an intermediary component between the first and second housing structures. This sealing member prevents direct contact and friction between the rigid housing structures while maintaining their movable coupling, thereby resolving the friction and noise issue without compromising portability
Solution Approach 2:
The sealing member is implemented as a flexible component that can accommodate the movement and rotation of the housing structures. This flexible sealing element prevents friction between rigid structures while allowing the desired portability and screen size functionality
2Object-generated harmful factors
If a gap is left between rubbing portions of outer structures, then friction and noise are reduced, but foreign bodies can enter and contaminate internal components
Solution Approach 1:
The sealing member serves as a mediator that fills the gap between housing structures. It maintains the space needed to reduce friction while simultaneously blocking foreign bodies from entering the internal components, thus resolving both issues simultaneously
Solution Approach 2:
The flexible sealing member creates a barrier that prevents foreign body contamination while allowing the housing structures to move relative to each other with reduced friction
3Object-affected harmful factors
If sealing members are added between housing structures, then foreign body contamination is prevented, but device complexity increases
Solution Approach 1:
The sealing member is implemented as a simple flexible component rather than a complex mechanical system. This straightforward approach prevents foreign body contamination while minimizing the increase in device complexity
