Solution Overview

Problem

Existing agricultural vehicle combinations with hose couplers face complex data transmission challenges in determining the plug-in position, leading to potential malfunctions and inefficiencies in assigning hydraulic or pneumatic functions.

Innovation Solution

A connection panel with receiving and transmitting coils allows for the identification of hose couplers through unique current signals, eliminating the need for simultaneous coupler identifier transmission, and includes an evaluation unit for self-configuration and operator feedback to ensure correct plug-in positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If RFID transponders and readers are used to determine hose coupler positions, then individual coupling identification can be transmitted, but the data transmission becomes comparatively complex

Engineering Contradiction:
Improveindividual coupling identificationVSAvoiddata transmission
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the identification function from the hose coupler side and places it on the connection socket side. The transmitting coil with identifier is located in the connection socket, while the receiving coil is in the hose coupler. This reversal eliminates the need for complex simultaneous transmission of coupler identifiers, simplifying the data transmission system while maintaining reliable identification.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of information

If simultaneous transmission of coupler identifier and functional assignment is required, then complete information can be exchanged, but data transmission complexity increases significantly

Engineering Contradiction:
Improveinformation completenessVSAvoiddata transmission
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent inverts the traditional approach by having the connection socket (stationary element) transmit its identifier to the hose coupler (moving element) instead of the reverse. The transmitting coil is in the connection socket and the receiving coil is in the hose coupler. This inversion allows the identifier to be transmitted in one direction only, eliminating the need for simultaneous bidirectional communication and significantly reducing data transmission complexity.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of operation

If hose couplers are connected to any coupling socket without verification, then ease of operation is improved, but malfunctions may occur due to incorrect function assignment

Engineering Contradiction:
Improveconnection flexibilityVSAvoidfunction assignment accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the evaluation unit receives the transmitted identifier from the connection socket, determines the correct plug-in position based on this identifier, and can provide feedback to guide the operator. This ensures that hose couplers are connected to the correct coupling sockets for their intended function, maintaining both ease of operation through automatic detection and reliability through accurate function assignment.

Inventive Principle:
Principle #23Feedback
