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

VSEngineering 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

Engineering Contradiction:
Improveadjustability to different numbers of crimp connectionsVSAvoidconnection structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvematerial waste from overuse or underuse of connectionsVSAvoidmanufacturing simplicity
Core Design Contradiction:
Loss of substanceVSEase of manufacture

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveprocessing speedVSAvoidflexibility to match different connection requirements
Core Design Contradiction:
ProductivityVSAdaptability or versatility

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.
