Solution Overview

Problem

Self-propelled agricultural harvesting machines, such as forage harvesters, require drivers to manually adjust numerous parameters when starting to harvest a new field, leading to increased risk of errors, crop losses, and accidents due to the complexity of coordinating cutting and transfer processes under time pressure and poor visibility.

Innovation Solution

A control device that allows activation of a 'field cutting mode' to automatically or recommendably set parameter settings for functional devices like cutting height, conveying speed, and automatic functions, reducing the driver's workload and minimizing the risk of errors by pre-configuring the machine for initial field cutting operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the driver manually adjusts numerous parameters when starting to harvest a new field, then the harvesting machine can be configured for optimal performance, but the risk of errors, crop losses, and accidents increases due to the complexity of coordinating cutting and transfer processes under time pressure and poor visibility

Engineering Contradiction:
Improverisk of errorsVSAvoiddriver workload
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The control device stores predetermined parameter settings for field cutting mode in advance. When the mode is activated, these pre-configured settings are automatically applied to multiple functional devices, eliminating the need for the driver to manually adjust each parameter during the critical field cutting phase, thereby reducing errors while maintaining operational capability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The harvesting machine's control system automatically manages the configuration of multiple functional devices when field cutting mode is activated. The system self-adjusts parameters for cutting height, conveying speed, and other functions without requiring continuous manual intervention from the driver, reducing workload while maintaining proper machine configuration

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If the driver manually configures multiple functional devices for field cutting mode, then the machine can be optimized for the specific harvesting situation, but the time required for configuration increases, reducing productivity under time pressure

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidharvesting speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

Optimal parameter settings for field cutting mode are predetermined and stored in the control device before harvesting operations begin. When the mode is activated, these pre-configured settings are instantly applied to multiple functional devices, maintaining configuration adaptability while eliminating the time-consuming manual adjustment process that would reduce productivity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control device combines multiple parameter adjustments for different functional devices into a single automated operation. By merging the configuration of cutting height, conveying speed, and other parameters into one unified mode activation, the system maintains comprehensive adaptability while dramatically reducing the time required for configuration, thus preserving productivity under time pressure

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If the driver deactivates automatic functions such as cruise control and automatic overloading for field cutting, then the machine can be manually controlled for precision, but the complexity of manual coordination increases, leading to more errors

Engineering Contradiction:
Improvecontrol precisionVSAvoidcontrol system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control system dynamically adapts its behavior based on the operating mode. When field cutting mode is activated, the system automatically adjusts parameter settings for functional devices while allowing automatic functions to remain active. This dynamic adaptation maintains control precision through automated adjustments while reducing the complexity of manual coordination that would otherwise be required

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control device changes operational parameters automatically when field cutting mode is activated. Instead of requiring manual deactivation of automatic functions, the system modifies parameters such as cutting height, conveying speed, and other settings through automated control, maintaining precision while reducing the complexity of manual coordination and the risk of driver error

Inventive Principle:
Principle #35Parameter changes
