Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent heating films and glasses face challenges in achieving high transmittance while maintaining conductivity and avoiding signal shielding effects, which limits their heating efficiency and popularization due to the restrictive relationship between transmittance and conductivity, as well as the shielding of mobile phone signals.
Innovation Solution
A transparent heating film with a conductive grid formed by filling trenches in a grid shape on a transparent supporting body, incorporating penetration windows that allow signal penetration and a color matching grid to prevent electrical connection, achieving high transmittance, low square resistance, and rapid heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transmittance is improved to ensure better visual effect, then visual clarity is enhanced, but conductivity property is affected, thereby reducing heating efficiency
Solution Approach 1:
The conductive layer is segmented into a grid pattern rather than being continuous, creating discrete conductive paths that minimize light blocking while maintaining electrical conductivity for heating functionality
Solution Approach 2:
Different regions of the heating film have different properties: the grid lines provide conductivity while the penetration windows provide high transmittance, allowing each region to optimize its local function
2Stability of the object's composition
If a homogeneous coating is used to achieve uniform heating, then heating coverage is improved, but signal penetration is blocked, thereby creating a shielding effect on mobile phone signals
Solution Approach 1:
The continuous homogeneous coating is segmented into a grid pattern with penetration windows, creating discrete conductive regions that maintain heating uniformity while allowing signal penetration through the windows
Solution Approach 2:
The grid structure creates a porous-like configuration with penetration windows that allow electromagnetic signals to pass through while the conductive grid portions maintain heating functionality

AI summary
Disclosed are a transparent heating film and a heating glass including the transparent heating film. The transparent heating film includes a transparent supporting body, a conductive grid, and a penetration window. A side of the transparent supporting body is provided with a plurality of trenches interconnected to each other in a grid shape; the conductive grid is formed by filling the plurality of trenches with a conductive material; and the penetration window is located between and partitioned with the conductive grid. The penetration window located between the conductive grid may disrupt or weaken a shielding effect of the conductive grid, thereby facilitating penetration of a signal.
