Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of self-propelled agricultural working machines face challenges in determining which crop-material or working parameters limit ground-speed control, requiring technical knowledge to adjust settings for optimal throughput, and existing systems lack clear information on limiting factors.
Innovation Solution
A self-propelled agricultural working machine with a forward-travel regulator that automatically adjusts ground speed based on crop-material or working parameters, equipped with a control and display unit that informs the operator of the limiting parameter, allowing for intuitive and targeted adjustments to maintain optimal performance.

Engineering Contradiction Analysis
1Productivity
If ground speed is increased to maintain throughput when crop stands are thin, then productivity is improved, but driving stability and safety deteriorate due to maximum speed limitations
Solution Approach 1:
The control unit continuously monitors the limiting parameter (e.g., maximum working speed) and provides feedback to the operator through the display unit. When the ground speed regulator attempts to increase speed beyond the permissible limit, the system detects this constraint and communicates it to the operator, enabling informed decisions about whether to adjust working parameters or accept reduced throughput.
2Productivity
If the operator modifies working parameters to compensate for throughput loss, then productivity can be maintained, but the complexity of operation increases due to required technical knowledge
Solution Approach 1:
The control and display unit acts as an intermediary between the ground speed regulator and the operator. Instead of requiring the operator to have deep technical knowledge about which parameters to adjust, the system automatically identifies the limiting parameter (such as maximum working speed or engine load) and presents this information clearly to the operator, who can then make simple, informed decisions about parameter adjustments.
3Productivity
If automatic ground speed control is implemented to optimize throughput, then productivity is improved, but the operator loses information about which parameters are limiting performance
Solution Approach 1:
The system incorporates a feedback mechanism where the control unit continuously monitors system parameters and automatically identifies which parameter is currently limiting the ground speed regulator's performance. This information is then fed back to the operator through the display unit, ensuring that the operator always knows whether the limitation comes from maximum working speed, engine load, or other factors.
Solution Approach 2:
The control system performs self-diagnosis to automatically identify and communicate the limiting parameter to the operator. Rather than requiring the operator to manually monitor and interpret complex system data, the system serves itself by automatically detecting constraints (such as when ground speed is limited by maximum working speed) and presenting this information in an easily understandable format through the display unit.

AI summary
In a self-propelled agricultural working machine having working units whose working parameters are adjustable, moving at a ground speed that is regulated automatically as a function of at least one crop-material parameter and/or one working parameter of the working machine using a forward-travel regulator, and having at least one control, operating, and display unit, with which the crop-material parameters and/or the working parameters of the working machine may be adjusted and displayed, the operator of the working machine has access to information regarding the state of the forward-travel regulator when the ground speed is being regulated using a forward-travel regulator. For this purpose, the crop-material parameter and/or working parameter of the working machine that currently limits the ground-speed control via the forward-travel regulator is displayed directly to the operator of the working machine in the control, operating, and display unit.
