Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face challenges in expanding display area without compromising portability, particularly in slidable types where the sliding structure moves relative to a fixed structure, affecting the exposure area of the flexible display.
Innovation Solution
The electronic device utilizes a side cover as an antenna radiator by incorporating an antenna contact structure, where at least part of the side cover passes through a guide rail, allowing for an expanded display area while maintaining portability.

1Area of moving object
If a guide rail is disposed to face a side cover that operates as an antenna radiator, then the sliding structure can move relative to the fixed structure to expand the display area, but the antenna radiation function may be compromised due to interference from the guide rail structure
Solution Approach 1:
The guide rail is divided into a first guide rail and a second guide rail that are disposed at different positions. The first guide rail is positioned to avoid interfering with the antenna radiation, while the second guide rail provides the necessary sliding guidance. This segmentation allows the sliding structure to function without compromising the antenna radiation function.
Solution Approach 2:
The guide rails are disposed in different spatial dimensions and orientations. By positioning the guide rails at different locations and angles, the design creates three-dimensional spatial separation that allows both the sliding mechanism and antenna radiation to coexist without interference.
2Reliability
If the side cover passes through the guide rail to implement antenna contact structure, then the antenna radiation function is improved, but the structural complexity increases
Solution Approach 1:
The side cover serves multiple functions: it acts as both a structural component that passes through the guide rail and as an antenna radiator. By making the side cover multi-functional, the design reduces the need for additional separate components, thereby managing structural complexity while improving antenna radiation function.
Solution Approach 2:
The antenna contact structure is merged with the side cover and guide rail assembly. Rather than adding a separate antenna mechanism, the design combines the antenna radiation function with existing structural elements, reducing overall structural complexity while achieving reliable antenna radiation.
