Solution Overview

Problem

Existing agricultural working machines, such as self-propelled harvesters, face challenges in evenly distributing crops into transport containers during transfer processes, requiring high energy consumption and reaction time to adjust spout angles or vehicle speeds.

Innovation Solution

An operator assistance system controls a deflection mechanism within the spout to dynamically adjust the crop flow direction, reducing energy consumption by allowing more precise control over the outlet mouth's position, both longitudinally and laterally, using actuators to adjust the outlet mouth's orientation relative to vertical and horizontal planes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the spout is pivoted or vehicle speed is changed to distribute crops evenly, then crop distribution improves, but energy consumption and reaction time increase

Engineering Contradiction:
Improvecrop distributionVSAvoidenergy consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The spout is divided into multiple segments that can be independently adjusted. Instead of pivoting the entire spout, only specific segments are adjusted to change crop flow direction, reducing the energy and mass involved in the adjustment while achieving the same distribution effect.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spout segments are made dynamically adjustable during operation, allowing real-time modification of crop flow direction without stopping the harvesting process. This dynamic adjustment capability enables precise control with minimal energy input compared to static repositioning of the entire spout.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the spout is pivoted to adjust crop flow direction, then distribution control improves, but power demand increases

Engineering Contradiction:
Improvedistribution controlVSAvoidpower demand
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

The spout is segmented into adjustable sections, allowing distribution control to be achieved by moving only small segments rather than the entire heavy spout structure. This dramatically reduces the power demand while maintaining ease of operation for distribution control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Adjustable guide elements or deflectors are introduced as intermediaries within the spout system. These intermediaries redirect crop flow without requiring movement of the entire spout, reducing power demand while preserving distribution control capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If vehicle speed is continuously altered to distribute crops, then crop distribution improves, but reaction time increases

Engineering Contradiction:
Improvecrop distributionVSAvoidreaction time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The spout is segmented into adjustable sections, allowing immediate local adjustments to crop flow direction without waiting for vehicle speed changes to take effect. This provides faster reaction time while achieving the same distribution precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spout segments are made dynamically adjustable during operation, allowing real-time modification of crop flow direction without stopping the harvesting process. This dynamic adjustment capability enables precise control with minimal energy input compared to static repositioning of the entire spout.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention is directed to an agricultural working machine comprising a spout (2) for conveying harvested crops forming a crop flow (3) to a transport container (4), preferably of a transport vehicle (5), in a transfer process, wherein the spout (2) comprises at his distal end a deflection mechanism (6) forming an outlet mouth (7) for the crop flow (3) and wherein the deflection mechanism (6) comprises an actuator arrangement (8) for adjusting at least part of the outlet mouth (7) in order to change the flow direction (F1, F2) of the crop flow by deflection and wherein the agricultural working machine (1) further comprises an operator assistance system (9), which controls the deflection mechanism (6). It is proposed that the deflection mechanism (6) may be controlled by the operator assistance system (9) such that for distribution of the crops in the transport container (4) along the drive direction (D) of the agricultural working machine (1) during a side-by-side transfer process of the agricultural working machine (1) and the transport container (4) the change in flow direction (F1, F2) may comprise a deflection component (DD) in drive direction of the agricultural working machine (1).
