Vehicle Window Ribbon Conductor Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional structural units for vehicle windows with protruding ribbon conductors complicate installation, are prone to damage, and increase production and transportation challenges due to the need for additional routing and potential for electrical connection loosening or damage.
Innovation Solution
A structural unit with a pane carrier that integrates an electrical contact element within a receptacle, allowing the ribbon conductor to be routed between panes and attached to the vehicle window surface, providing a secure and cost-effective electrical connection without the need for external cables, and ensuring mechanical and electrical contact during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat ribbon conductor protrudes from the vehicle window to provide freedom of movement, then the electrical connection flexibility is improved, but the risk of damage and disconnection during installation and operation increases
Solution Approach 1:
The flat ribbon conductor is routed between the two individual panes of the laminated vehicle window, nesting the conductor within the window structure itself. This eliminates the protruding conductor while maintaining electrical connection flexibility, as the conductor can still move with the window during lowering operations without being exposed to external damage risks.
Solution Approach 2:
The conductor routing moves from a three-dimensional external path (protruding from the window) to a two-dimensional internal path (between the panes). This dimensional change allows the conductor to remain protected within the window assembly while still providing the necessary flexibility for electrical connections during window operation.
2Ease of operation
If a flat ribbon conductor protrudes from the vehicle window, then electrical connection is achieved, but the complexity of installation and routing increases
Solution Approach 1:
The mechanical window assembly and electrical connection system are merged into a single integrated structure. The flat ribbon conductor is incorporated between the panes during window manufacturing, so that installing the window automatically installs the electrical connection without separate routing steps, significantly reducing installation complexity.
Solution Approach 2:
The electrical conductor is pre-routed and positioned between the panes during window manufacturing before the window is installed in the vehicle. This preliminary action eliminates the need for complex on-site routing and connection work, simplifying the installation process while ensuring proper electrical connectivity.
3Ease of operation
If perforations are made in the vehicle windshield to create electrical contacts, then electrical connection is achieved, but the manufacturing cost and reject rate increase
Solution Approach 1:
The electrical contact creation process is extracted from the windshield manufacturing process itself. Instead of requiring perforations during windshield production, the flat ribbon conductor is routed between the panes after the windshield is manufactured, eliminating the need for costly and reject-prone perforation operations while still achieving electrical connectivity.
