Trailer Socket Adapter with Dual Contact Standards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of adapter solutions for trailer sockets that allow for the connection of trailer plugs with different standards, such as European and American standards, without requiring complex conversion measures or specific sockets, limiting the versatility of trailer couplings across different markets.
Innovation Solution
An adapter with a secondary contact arrangement according to the US American standard is integrated into a base body with a primary contact arrangement following European or German standards, enabling an electric connection between a trailer plug and socket, and incorporating diode elements to prevent feedback between brake light and direction indicator contacts, ensuring compatibility and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If country-specific sockets or socket wiring are provided for different standards, then compatibility with specific trailer plugs is achieved, but device complexity and cost increase
Solution Approach 1:
The adapter enables a single European trailer socket to universally connect with both European and American trailer plugs by incorporating dual contact arrangements (primary European contacts and secondary American contacts) within one device, eliminating the need for separate country-specific sockets
Solution Approach 2:
The adapter acts as an intermediary device between the European trailer socket and American trailer plug, providing the necessary contact arrangement conversion without modifying the original socket or requiring complex wiring changes
2Adaptability or versatility
If conversion measures or specific sockets are provided for different standards, then compatibility with American trailer plugs is achieved, but ease of operation and installation deteriorate
Solution Approach 1:
The adapter is designed as a self-contained unit with pre-configured contact arrangements that automatically provide the correct electrical connections when inserted into the European socket, eliminating the need for complex conversion measures or professional installation
3Reliability
If diode elements are added to prevent feedback between brake light and direction indicator contacts, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The adapter prevents potentially harmful feedback between brake light and direction indicator circuits by incorporating diode elements that block reverse current flow, converting a potential safety hazard into a reliable electrical connection

AI summary
An adapter for a trailer socket of a trailer coupling for coupling a trailer, wherein the adapter comprises a base body and a primary contact arrangement mounted thereon and comprising a plurality of primary contacts corresponding to a European or German standard, in particular seven primary contacts according to DIN 1724 or thirteen primary contacts according to ISO 11446, for establishing an electric connection to corresponding socket contacts of the trailer socket. The adapter comprises a secondary contact arrangement mounted on the base body with secondary contacts according to a US American standard, so that a trailer plug corresponding to the US American standard can be electrically connected to the secondary contact arrangement for the power supply of a trailer, the secondary contact arrangement and the primary contact arrangement being connected to one another via an electric connection arrangement.
