Flexible Display Link Mechanism for Smooth Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices face challenges in smoothly accommodating and supporting extended screens due to internal space constraints and durability issues when the flexible display is pulled out, leading to potential damage from unrestricted deformation.
Innovation Solution
A flexible display device design featuring a first and second body with a link part that allows relative movement, including rotatable link members arranged in a hexagonal shape, to guide the second body's movement and provide elastic support, enabling smooth extension and retraction of the flexible display while maintaining structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the flexible display is pulled out to increase exposed area, then the screen size is increased, but the flexible display lacks proper support and durability decreases due to unrestricted deformation
Solution Approach 1:
A support structure comprising a support rod and support plate is introduced as an intermediary element between the flexible display and the terminal body. The support rod connects to the support plate which in turn supports the flexible display, providing necessary mechanical support and preventing unrestricted deformation when the display is extended, thereby maintaining durability while allowing increased exposed area.
2Adaptability or versatility
If many components are added to utilize deformable characteristics, then the functional requirements are met, but the structure becomes complicated and internal space utilization becomes difficult
Solution Approach 1:
The support structure is segmented into distinct functional components: a support rod for providing structural backbone, a support plate for distributing load and providing mounting surface, and a connection structure for enabling controlled movement. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure manageable and space-efficient.
3Area of moving object
If the flexible display is extended from the body, then the exposed area is increased, but an empty space is generated inside the body and the extended portion cannot be properly supported
Solution Approach 1:
The support structure acts as a mediator that fills and utilizes the empty space created during extension. The support rod and support plate are positioned within the terminal body to occupy the void space, providing mechanical support to the extended flexible display portion and maintaining structural stability throughout the extension process.
