Flexible Display Hinge Housing That Blocks Foreign-Object Antenna Conduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The housing structure of electronic devices with foldable displays has an unfixed structure due to the placement of the foldable flexible display, leading to gaps between components that can allow foreign objects, such as impure water, to enter and cause conduction between separated antennas, degrading communication performance.
Innovation Solution
The electronic device includes a first housing, a second housing connected by a hinge structure, and a flexible display extending between them. At least one housing includes antennas and a segmenter between them, with a separation member adjacent to the segmenter and protruding towards the flexible display. Additionally, an adhesive member is disposed between the housings and a plate on the flexible display, with a plate protrusion and adhesive member protrusions to further prevent foreign object conduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a foldable flexible display is placed over the entire area of the housing structure, then the display area is increased, but the housing structure becomes unfixed and gaps are created between components
Solution Approach 1:
The housing is divided into multiple housing members (first housing member, second housing member, third housing member, fourth housing member) that can be separately positioned and connected. This segmentation allows each housing member to independently support the flexible display while maintaining overall structural stability, resolving the contradiction between large display area and structural stability.
2Adaptability or versatility
If the housing structure is unfixed due to foldable display placement, then the display can fold, but foreign objects can enter through gaps and cause conduction between antennas
Solution Approach 1:
A waterproof adhesive member is introduced as an intermediary substance between the housing members and the flexible display. This adhesive member fills gaps and prevents foreign objects from entering the space between antennas, thereby maintaining communication reliability while preserving the folding capability of the display.
3Ease of operation
If gaps are created between components for foldable display, then the display can be flexible, but conduction between separated antennas may occur
Solution Approach 1:
The waterproof adhesive member, which could be seen as an additional component complicating the structure, actually benefits the device by converting the harmful effect of gaps (which allow foreign object entry) into a beneficial sealing function. The adhesive fills the necessary gaps for flexibility while preventing foreign object conduction between antennas.
