Tractor Supply Console for Mixed Trailer Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for connecting supply lines between tractors and semi-trailers require full retrofitting of both vehicles with automated line coupling systems to function seamlessly, leading to compatibility issues in mixed truck parks where conventional semi-trailers cannot be properly powered or signaled by retrofitted tractors.
Innovation Solution
A second supply console is integrated on the tractor, connected to the automated line coupling system's jack connection, allowing the plug-in element to be optionally inserted at either the first or second console, enabling compatibility with both automated and conventional semi-trailers by routing power and signals through the second console when needed, and directly to the first console when not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated line coupling systems are installed on tractors to reduce operating expenses and improve coupling automation, then the extent of automation and ease of operation are improved, but compatibility with conventional semi-trailers deteriorates because retrofitted tractors cannot supply power and control signals to conventional semi-trailers
Solution Approach 1:
The tractor is equipped with two supply consoles: a first supply console for automated coupling systems and a second supply console for conventional semi-trailers. This multi-functionality allows the same tractor to work with both automated and conventional semi-trailers, resolving the compatibility issue while maintaining automation benefits
2Reliability
If all tractors and semi-trailers in a fleet are fully retrofitted with automated line coupling systems to ensure seamless operation, then system compatibility and reliability are improved, but device complexity and retrofitting costs increase significantly
Solution Approach 1:
The supply system is segmented into two independent paths: one for automated coupling (via jack connection) and one for conventional coupling (via plug-in element). This segmentation allows selective use of automation components without requiring complete fleet retrofitting, reducing overall system complexity while maintaining reliability

AI summary
A system for connecting supply lines between a tractive vehicle and a semi-trailer that can be coupled to the latter, a semi-trailer coupling and an automatic line coupling system comprising at least one connector jack being situated on the tractive vehicle and the semi-trailer having at least one supply circuit comprising a first supply console for connecting to the tractive vehicle and for receiving a plug-in element that is located on at least one supply line of the tractive vehicle and/or a plug that is configured to fit the connector jack. The aim of the invention is to provide a system for connecting supply lines for tractive vehicles, comprising an automatic line coupling system that permits the coupling of conventional semi-trailers. To achieve this, a second supply console is located on the tractive vehicle and is permanently connected to the connector jack of the line coupling system and the plug-in element can be selectively connected to the first or second supply console.
