Solution Overview

Problem

Existing control systems for wired vehicle fleets struggle to prevent collisions between bendable connection elements, which are crucial for efficient energy and resource transfer between vehicles in agricultural settings, particularly when vehicles are moving and their connection heights vary.

Innovation Solution

A control system that includes a supply unit connected to two vehicles via bendable connection elements, with a control unit that adjusts the height of these elements and determines vehicle waylines to maintain a cascading arrangement, preventing collisions by ensuring one connection element's height is always lower than the other, and includes safety zones to anticipate and avoid potential collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If vehicles are allowed to move freely in a wired vehicle fleet, then operational flexibility and productivity are improved, but the risk of collision between bendable connection elements increases

Engineering Contradiction:
Improveoperational flexibilityVSAvoidcollision risk
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts the height of connection elements and recalculates waylines in real-time as vehicles move, allowing operational flexibility while maintaining collision avoidance through continuous adaptation of connection parameters

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control system continuously monitors vehicle positions and connection element states, using this feedback to dynamically adjust heights and waylines, ensuring collision-free operation while maintaining productive vehicle movement

Inventive Principle:
Principle #23Feedback

2Device complexity

If the height of bendable connection elements is fixed, then system complexity is reduced, but the ability to avoid collisions between connection elements is compromised

Engineering Contradiction:
Improveheight control mechanismVSAvoidcollision avoidance capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system employs variable height connection elements that can be dynamically adjusted through telescopic masts and winches, enabling collision avoidance while maintaining manageable system complexity through automated control

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control system changes the height parameter of connection elements dynamically based on vehicle positions and predicted trajectories, enabling collision avoidance without requiring complex mechanical structures by using automated parameter adjustment

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If waylines are planned without considering connection element heights, then path planning is simplified, but collisions between connection elements cannot be prevented

Engineering Contradiction:
Improvepath planning complexityVSAvoidcollision prevention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system dynamically recalculates waylines based on current connection element heights and predicted vehicle positions, integrating height considerations into path planning through automated real-time computation rather than fixed pre-planned routes

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control system performs preliminary recalculation of waylines before vehicle movements that could cause collisions, anticipating potential conflicts and adjusting paths in advance to prevent collisions between connection elements

Inventive Principle:
Principle #10Preliminary action
