Low-E Glass Layout for 4G/5G Radio Transmission and Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass bodies with Low-E films struggle to enhance radio wave transmissivity for 4G and 5G frequency bands, leading to weak indoor reception due to high linearity of radio waves, and this is in a trade-off with heat insulating performance.
Innovation Solution
A glass body configuration with a radio wave transmission region that includes multiple radio wave passage sections and conductive film sections, where the conductive film is strategically placed between adjacent radio wave passage sections to enhance heat insulating performance while maintaining radio wave transmissivity. The radio wave transmission region is designed with a diffusion structure to increase radio wave intensity and reception area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a Low-E film is formed on the glass plate to improve heat insulating performance, then heat insulating property is improved, but radio wave transmissivity deteriorates
Solution Approach 1:
The glass plate surface is divided into multiple radio wave passage sections (first through fourth sections) that are spaced apart from each other. Each section allows radio waves to pass through while the conductive film is formed in the regions between these sections. This segmentation enables the glass to maintain heat insulating performance through the conductive film while providing multiple pathways for radio wave transmission.
Solution Approach 2:
The conductive film is selectively formed only in specific regions (conductive film sections) between the radio wave passage sections, rather than covering the entire glass surface. This local application of the conductive film allows those specific areas to provide heat insulation while leaving other areas open for radio wave transmission, thus resolving the contradiction between heat insulation and radio wave transmissivity.
2Reliability
If opening portions are provided in the Low-E film to enhance radio wave transmissivity, then radio wave transmissivity is improved, but heat insulating performance deteriorates
Solution Approach 1:
Instead of providing large continuous opening portions in the Low-E film, the invention segments the transmission areas into multiple smaller radio wave passage sections. The conductive film is then formed in the spaces between these sections, creating a pattern that allows radio waves to pass through multiple discrete points while maintaining thermal insulation through the conductive film regions.
3Reliability
If parallel lines are provided on the Low-E film to improve radio wave transmissivity, then radio wave transmissivity is improved, but appearance quality deteriorates due to striped pattern
Solution Approach 1:
The invention avoids symmetric parallel line patterns that create visible stripes. Instead, it uses an asymmetric arrangement of multiple radio wave passage sections (first through fourth sections) with conductive film sections positioned between them. This asymmetric segmentation provides radio wave transmission functionality while creating a less visually obtrusive pattern that improves appearance quality.
