Solution Overview

Problem

Existing systems for automating the connection of media transmission between towing and towed vehicles are susceptible to environmental influences and lack flexibility and rigidity, making them unreliable for daily use and requiring manual, time-consuming processes that pose safety risks.

Innovation Solution

A vehicle combination with a multi-part connection system comprising plug-in units and a support device, including a transport device such as an articulated robot, and a support mechanism with actuators to ensure precise and automated plugging of electrical, compressed air, and data connections, using threaded components and locking mechanisms to secure the connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual connection of transmission lines is used, then flexibility and adaptability are maintained, but time consumption increases and safety risks arise

Engineering Contradiction:
Improvecoupling speedVSAvoidmanual intervention required
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The connection system enables automatic self-alignment and self-connection of plug-in units through the articulated robot transport device, eliminating the need for manual intervention. The system performs the coupling operation autonomously by transporting the plug-in unit to the correct position and securing it mechanically

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical connection operations are replaced by an automated robot system that transports and positions plug-in units. The articulated robot performs the coupling function previously requiring human operators to physically connect transmission lines

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Extent of automation

If rigid automated connection systems are used, then automation extent increases, but flexibility to accommodate vehicle movements decreases

Engineering Contradiction:
Improveautomation levelVSAvoidflexibility to vehicle movements
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The connection system incorporates flexible elements including hoses and cables that can dynamically adapt to vehicle movements. The articulated robot transport device can adjust its positioning to accommodate relative movements between towing and towed vehicles while maintaining the connection

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection system is divided into modular plug-in units that can be independently positioned and connected. This segmentation allows each unit to be flexibly positioned by the robot while maintaining overall system connectivity and adaptability to vehicle movements

Inventive Principle:
Principle #1Segmentation

3Productivity

If automated connection systems are used, then productivity increases, but reliability under environmental influences decreases

Engineering Contradiction:
Improvecoupling automationVSAvoidresistance to environmental influences
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The connection system incorporates protective measures against environmental influences such as sealed connections and protected cable routing. The plug-in units are designed with protective features that cushion against dirt, moisture, and other environmental factors before they can affect the connection reliability

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system uses robust, easily replaceable plug-in units that can withstand environmental conditions. If a connection component is damaged by environmental factors, it can be quickly replaced by the automated system, maintaining overall reliability through redundancy and ease of replacement

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Reliability

If precise automated plugging is implemented, then connection reliability improves, but device complexity increases

Engineering Contradiction:
Improveconnection reproducibilityVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The articulated robot transport device serves as an intermediary between the plug-in unit and the connection point. It provides precise positioning and controlled movement, ensuring reliable connection without requiring complex alignment mechanisms in the plug-in units themselves

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The robot transport device performs multiple functions including transporting the plug-in unit, positioning it precisely, and potentially assisting in the connection process. This multi-functionality reduces the need for separate specialized mechanisms, managing overall system complexity while achieving precise automated plugging

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