Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly the fourth generation communication system, face limitations in bandwidth, which hinder the realization of high-quality, high-rate data services needed for emerging applications like 5G and multimedia consumption, leading to issues such as screen interference and dirty screens during video watching on smartphones.
Innovation Solution
The integration of a high-frequency module with a gesture sensing antenna in electronic devices, such as smartphones and smart glasses, that operates in a frequency bandwidth of 60 GHz or higher, allowing for gesture sensing and improved communication capabilities while being integrated into the device's display panel structure, including a stacked structure with image and touch screen layers, and positioned on the bezel or cover glass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna is integrated into the display panel structure, then the device complexity is reduced and space is saved, but the antenna performance may be affected by the display layers and touch screen layers
Solution Approach 1:
The patent positions the antenna in the stacked structure of the display panel, utilizing the vertical dimension (z-axis) through multiple layers including the cover glass, touch screen panel layer, and image display layer. This dimensional approach allows the antenna to be integrated without occupying additional lateral space while maintaining electromagnetic wave propagation characteristics through careful layer selection and arrangement.
Solution Approach 2:
The patent introduces a connecting member as an intermediary component between the antenna and the RF signal processing circuit. This connecting member serves as a mediator that facilitates electrical connection while isolating the antenna from potential interference sources, thereby maintaining antenna performance despite integration into the display panel structure.
2Ease of manufacture
If the second connecting member is made more flexible than the first connecting member, then the ease of manufacture is improved and assembly is facilitated, but the structural strength and stability may be reduced
Solution Approach 1:
The patent applies different flexibility characteristics to different connecting members based on their specific functional requirements. The first connecting member (supporting the RF signal processing circuit) is designed with higher strength and rigidity, while the second connecting member (connecting the antenna) is designed with greater flexibility to facilitate assembly. This localized differentiation of mechanical properties allows each component to optimize its performance for its specific role.
