Adjustable Electrical Solder Connection for Vehicle Panes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connections are limited to three or six crimp connections, leading to overuse or underuse in cases requiring different numbers, resulting in inefficient material usage and processing.
Innovation Solution
The electrical connection is designed with a plug extending parallel to the underside and a plug opening with a locking pin, allowing for adjustable crimp connections by forming a larger terminal block with the catch and latch, enabling precise adjustment and soldering for the correct number of crimp connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical connections are designed for fixed three or six crimp connections, then the connection structure is simple and standardized, but it leads to overuse or underuse of connections when different numbers are required
Solution Approach 1:
The terminal block is divided into multiple individual connection positions (three or six) that can be independently activated. Each position can be selectively soldered to the window based on the required number of crimp connections, allowing the system to adapt from 1 to 6 connections without requiring different terminal block designs.
Solution Approach 2:
A single terminal block design serves multiple functions by supporting different numbers of active connections (1-6) within the same physical structure. The universal design eliminates the need for multiple specialized terminal blocks for different connection counts, reducing overall system complexity while increasing adaptability.
2Loss of substance
If fixed-number terminal blocks are used, then manufacturing and inventory management are simplified, but material waste increases due to overuse or underuse
Solution Approach 1:
The terminal block transitions from a static fixed-connection design to a dynamic configurable design where the number of active connections can be adjusted during installation. This dynamic capability allows the system to match the exact number of connections needed, eliminating material waste from overuse while maintaining ease of manufacture through a standardized base design.
3Productivity
If multiple fixed-number connection types are maintained, then each connection type is optimized for its specific use, but processing time increases due to matching requirements
Solution Approach 1:
The terminal block is designed as a universal component that can accommodate any number of crimp connections from 1 to 6 within a single design. This eliminates the need for technicians to match specific terminal block types to connection requirements, significantly reducing processing time while maintaining full adaptability to different connection needs.

AI summary
An electrical connection having a planar underside for electrical devices provided on panes of motor vehicles, such as heating arrays, antennas or the like, in the form of at least one crimp connection having a planar soldering pad, to be soldered onto the pane, and a crimp fixed to said soldering pad, said crimp fixing an electrical cable in the crimp connection, wherein the at least one crimp connection can be inserted into an opening - adapted to the outer contour thereof - in a terminal strip in an immovable manner and can be fixed together with the latter by the soldering of the soldering pad to the pane, is distinguished by the fact that the connection is provided with a plug - extending parallel to the underside - with a latch at one end of said connection and, at its other end lying opposite thereto, is provided with a plug opening having a latching pin.
