Solution Overview
Problem
Current methods for producing laminated vehicle panes are inefficient, lacking a cost-effective and energy-efficient process for integrating electrically conductive coatings and printed portions that enable heating and infrared radiation reflection while concealing electrical components.
Innovation Solution
A laminated pane design featuring an electrically conductive coating on one surface with an integrated electrically conductive printed portion, applied via thermal deposition or etching, which is connected to the vehicle's wiring system for heating and infrared reflection, and a non-conductive printed portion for visual concealment of electrical elements, allowing a single heating step for both curing and bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple separate processes are used to apply electrically conductive coating and printed portions, then manufacturing precision can be improved, but device complexity and production time increase
Solution Approach 1:
The patent combines the application of electrically conductive coating and printed portions into a single process step. The conductive coating is applied to the glass pane, and then the printed portions (both conductive and non-conductive) are applied in the same process sequence, eliminating the need for separate coating and printing processes. This merging reduces device complexity while maintaining manufacturing precision through controlled single-pass application.
Solution Approach 2:
The electrically conductive coating is applied to the glass pane before the printed portions are applied. This preliminary action allows the coating to be in place and cured before the printed portions are added, ensuring proper adhesion and integration. The preliminary application of coating enables subsequent printing processes to build upon a stable foundation without requiring re-coating or re-processing.
2Manufacturing precision
If separate heating steps are used for curing coating and bending pane, then manufacturing precision is improved, but loss of time and energy increase
Solution Approach 1:
The patent merges the curing of the electrically conductive coating and the bending of the glass pane into a single heating step. The heating process simultaneously cures the coating material and induces the desired curvature in the glass pane, eliminating the need for separate heating operations. This reduces production cycle time while maintaining precision through controlled thermal parameters that achieve both objectives in one process.
Solution Approach 2:
The heating process continues uninterrupted to perform multiple functions: first curing the electrically conductive coating, then inducing the bending of the glass pane. This continuous heating action ensures that both processes complete without idle time between steps, maximizing energy efficiency and reducing overall production time while maintaining manufacturing precision.
3Ease of manufacture
If electrically conductive printed portion is applied on the side facing away from the first pane, then ease of manufacture is improved, but object-affected harmful factors increase due to potential electrical interference
Solution Approach 1:
The patent introduces a non-conductive printed portion as an intermediary layer between the electrically conductive printed portion and the glass pane. This intermediary non-conductive layer acts as an electrical barrier, preventing harmful electrical interference with the pane while still allowing the conductive printed portion to function for heating and infrared reflection. The intermediary layer isolates the conductive elements from direct contact with the pane, eliminating the harmful effect while preserving manufacturing ease.
4Illumination intensity
If transparent conductive oxide is used for electrically conductive coating, then translucency is improved, but electrical conductivity decreases compared to metal coatings
Solution Approach 1:
The patent uses a composite structure combining transparent conductive oxide (TCO) with metal particles or layers in the electrically conductive coating. The TCO provides translucency and basic conductivity, while the embedded metal particles or layers enhance the electrical conductivity. This composite material approach allows the coating to achieve both high translucency and sufficient electrical conductivity for heating and infrared reflection applications, resolving the trade-off between transparency and conductivity.

Function Achieved in This Case
This design enhances energy efficiency by reducing production costs and complexity, enabling effective de-icing, condensation removal, and reduced heat input from outside, while maintaining an aesthetically concealed electrical infrastructure.
Implementation Method 1
The electrically conductive coating is preferably also configured to reflect infrared radiation. Thus, in particular in the installed state, a heat input from outside the vehicle into the interior of the vehicle is reduced.
Implementation Method 2
The electrically conductive coating serves, for example, for heating the laminated pane during operation. The electrically conductive coating thus functions during operation, for example, in the manner of an electrical resistance heater.
Implementation Method 3
the electrically conductive printed portion is connected, in particular is supplied, to the electrically conductive coating by means of thermal deposition
Implementation Method 4
the electrically conductive printed portion is at least partially diffused into the electrically conductive coating
