Sliding Housing Antenna Layout for Rollable Display Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with foldable or rollable displays face interference with antenna signals and durability issues due to metal sidewalls covering the antenna radiator and non-conductive resin materials, respectively.
Innovation Solution
The electronic device incorporates a first housing with a metal and non-metal area, and a second housing with a metal and non-metal area, allowing for selective use of either housing as an antenna radiator, reducing interference and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the sidewall of the second housing is formed of metal material, then the durability of the electronic device is improved, but the performance of the antenna using at least a portion of the first housing as an antenna radiator is lowered due to interference
Solution Approach 1:
The second housing is divided into a first sidewall formed of metal material and a second sidewall formed of resin material. This segmentation allows the metal first sidewall to provide durability while the resin second sidewall minimizes interference with antenna signals from the first housing.
Solution Approach 2:
Different portions of the second housing are made of different materials with different properties. The first sidewall uses metal for strength and durability, while the second sidewall uses resin for electrical insulation and reduced signal interference, optimizing each region for its specific function.
2Reliability
If the sidewall of the second housing is formed of resin material, then the interference with antenna signals is reduced, but the durability of the electronic device deteriorates
Solution Approach 1:
The second housing is divided into a first sidewall formed of metal material and a second sidewall formed of resin material. This segmentation allows the metal first sidewall to provide durability while the resin second sidewall minimizes interference with antenna signals from the first housing.
Solution Approach 2:
Different portions of the second housing are made of different materials with different properties. The first sidewall uses metal for strength and durability, while the second sidewall uses resin for electrical insulation and reduced signal interference, optimizing each region for its specific function.
3Area of stationary object
If the display size is increased to allow satisfactory use of multimedia services, then the user experience is improved, but the compactness of the electronic device is compromised
Solution Approach 1:
The electronic device employs a rollable display that can dynamically change its visible area. The display can be rolled out to provide a large viewing area for multimedia services and rolled in to maintain a compact form factor when the full display area is not needed, allowing the device to adapt its size based on usage requirements.
