Angular Sector Heating Conductor for Vehicle Pane Antenna Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle pane designs with heating conductors and antennas suffer from non-uniform appearance due to varying bus bar and feed line widths, and limited open spaces for antenna mounting, which affects antenna performance and visual quality.
Innovation Solution
A vehicle pane with a heating conductor field in the shape of an angular sector, allowing for enlarged open spaces for antenna mounting, and compact bus bar arrangement on a common edge, enabling flexible antenna design and improved electromagnetic coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If bus bar sections and feed lines are designed with varying width and thickness to send identical current through all heating conductors, then current distribution is improved, but visual appearance deteriorates due to non-uniform appearance
Solution Approach 1:
The heating conductor field is designed with angular sector shape, creating different local zones: a heated zone with heating conductors and bus bars, and a non-heated free area for antenna mounting. This local differentiation allows uniform-width bus bars in the heated zone while providing ample space in the free area for antennas, resolving the contradiction between current distribution and visual appearance.
2Ease of manufacture
If heating conductor field has rectangular basic shape, then manufacturing is simplified, but open space for antenna mounting is limited
Solution Approach 1:
The heating conductor field is segmented into distinct functional zones using the angular sector geometry: a triangular heated zone adjacent to the bus bar common edge, and a larger non-heated free area. This segmentation naturally separates heating functions from antenna mounting functions, providing ample open space for antennas while maintaining manufacturable geometry through standard angular patterns.
