Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent heating structures for vehicle windows, which incorporate metal wires or transparent electrodes, hinder the penetration of 5G communication electromagnetic waves, limiting their effectiveness in vehicle-to-vehicle communication.
Innovation Solution
A transparent heating structure is designed with a pattern portion on a transparent substrate, comprising cells with unit grids and slots that allow for high transmittance of 5G communication frequency bands while enabling heating to remove fogging or frost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If metal wires or transparent electrodes are used for heating glass, then heating function is achieved, but 5G communication electromagnetic waves cannot penetrate
Solution Approach 1:
The continuous transparent electrode is divided into multiple isolated unit grids arranged in a pattern. Each unit grid is a separate conductive element, creating gaps between them that allow electromagnetic waves to pass through while the collective arrangement maintains heating capability across the glass surface.
Solution Approach 2:
The transparent electrode is designed with non-uniform distribution - the pattern density varies across different regions of the glass. Edge regions have higher density of unit grids for enhanced heating where fogging occurs more frequently, while center regions have lower density to maximize 5G signal transmission where heating demand is lower.
2Temperature
If transparent electrodes are used for heating, then heating function is achieved, but visible light transmittance is reduced
Solution Approach 1:
The segmented unit grid structure reduces the total continuous conductive material coverage compared to a solid transparent electrode. The gaps between unit grids allow visible light to pass through with minimal obstruction while the conductive portions provide sufficient heating capability when electrical current is applied.
Solution Approach 2:
The unit grids are positioned asymmetrically with higher density at edges and lower density at center, optimizing the balance between heating performance (where needed most at edges) and light transmittance (where unobstructed view is most important at center).
