Flexible Display Rolling Guide Structure for Mounting Space Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slidable electronic devices with flexible displays face challenges in securing mounting space for other components when transitioning from a slide-out to a slide-in state, as a portion of the flexible display remains unfolded, obstructing space for other components.
Innovation Solution
A display rolling guide structure that guides a portion of the flexible display into the housing in a rolling manner, ensuring efficient space utilization and smooth unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display is accommodated in the inner space of the housing in a slide-in state, then the display area is reduced for portability, but mounting space for other electronic components is insufficient because a portion of the flexible display remains unfolded
Solution Approach 1:
The flexible display is nested within the housing structure through a rolling guide mechanism. When transitioning to the slide-in state, the flexible display rolls up and is accommodated within the inner space of the housing, similar to how a nested doll places smaller objects inside larger containers. This ensures complete retraction of the display without obstructing mounting space for other components.
Solution Approach 2:
The patent introduces a dynamic rolling guide structure that enables the flexible display to transition between unfolded and rolled states. The rolling guide includes movable components that allow the display to dynamically adjust its configuration, ensuring smooth rolling motion and complete retraction into the housing, thereby resolving the contradiction between display area and mounting space.
2Area of stationary object
If the flexible display is rolled into the housing, then mounting space is secured, but the rolling motion may be unstable without proper guidance
Solution Approach 1:
The rolling guide structure acts as an intermediary mechanism between the flexible display and the housing. It provides guided pathways and support structures that ensure the flexible display rolls smoothly and stably into the housing without unpredictable movements. The rolling guide includes guide rails, rollers, or other intermediary components that maintain controlled rolling motion, thereby ensuring reliability while securing mounting space.
