Flexible Display Multi-Bar Rail Layout for Stable Antenna Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible displays face challenges in maintaining stable antenna performance due to the presence of a multi-bar structure that affects the antenna's operation environment.
Innovation Solution
The implementation of a multi-bar structure with a support surface and rails that are partially disposed in overlapping areas with the flexible display, allowing the flexible display to be deformable and supported while maintaining a sufficient gap from the antenna, thereby securing stable antenna performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a multi-bar structure is used to support the flexible display, then the structural support and deformability are improved, but the antenna operation environment is degraded
Solution Approach 1:
A rail structure is introduced as an intermediary component between the multi-bar support structure and the flexible display. The rail is disposed to overlap with the display area, creating a spatial buffer that allows the multi-bar structure to provide support while preventing direct interference with antenna operations. This intermediary element mediates the conflict between structural support needs and antenna performance requirements.
Solution Approach 2:
The rail structure extends in a direction overlapping with the display area, utilizing spatial arrangement in multiple dimensions. By positioning the rail to overlap with both the display and antenna regions, the design creates a three-dimensional spatial relationship that resolves the two-dimensional conflict between support structure and antenna operation.
2Area of moving object
If the screen display area is expanded using a flexible display, then the portability is improved, but the antenna operation stability is worsened
Solution Approach 1:
The support structure is segmented into multiple bars with a rail component, allowing different segments to perform different functions. The multi-bar structure provides mechanical support for the expanded display area, while the rail segment specifically manages the spatial relationship with the antenna, enabling the system to accommodate a larger display without compromising antenna stability.
3Volume of moving object
If the multi-bar structure is positioned adjacent to the antenna, then the device size is reduced, but the antenna performance is degraded
Solution Approach 1:
The rail structure serves as a mediator that enables close positioning of the multi-bar support structure to the antenna while maintaining antenna performance. The rail's spatial arrangement creates an overlapping configuration that allows compact device design without direct interference between the support structure and antenna operations.
