Solution Overview
Problem
Conventional methods for manufacturing heat-generating glass panels face issues such as extended curing times for electrically-conductive pastes, leading to energy loss and increased manufacturing costs, as well as high wiring costs and maintenance challenges due to the large number of heat-generating windows in collective housing.
Innovation Solution
A method involving fixing a metal strip on the electrically-conductive thin layer of a translucent panel, applying conductive paste, and using a heat-generating device with a flexible thin plate shape and elastic member to uniformly cure the paste, forming efficient electrodes with reduced energy loss and simplified wiring requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional hot air or far-infrared lamp curing methods are used for electrically-conductive paste, then the entire paste can be heated, but the curing time is extended and energy loss increases
Solution Approach 1:
The invention divides the heating process into segments by placing heating elements only at the edge regions of the plate where the conductive paste is applied. This segmented approach heats only the necessary areas through thermal conduction along the plate, rather than heating the entire plate surface, thereby reducing energy loss and curing time.
Solution Approach 2:
The invention applies local quality by concentrating heating resources at the edge regions where paste application occurs. The heating elements are positioned specifically at these locations to provide localized heating, which then conducts thermal energy through the plate to cure the paste uniformly without requiring energy to heat the entire plate surface.
2Reliability
If a large number of heat-generating glass windows are installed in collective housing, then thermal insulation is improved, but wiring complexity and maintenance costs increase
Solution Approach 1:
The invention merges multiple heating circuits into a single unified circuit by connecting heating elements in parallel. This allows all heat-generating windows to be controlled through one power supply and control system, significantly reducing wiring complexity and maintenance requirements while maintaining thermal insulation performance across multiple windows.
