Harvester Correction Factor Dialogue for Grain Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing correction factors for determining broken grain and non-grain proportions in harvesting machines are abstract and difficult for operators to adjust, leading to deviations from actual conditions and complicating the setting of evaluation devices.
Innovation Solution
A driver assistance system with a setting assistant that interacts with the operator through a dialogue to set a correction factor, allowing adjustment based on actual conditions and optimizing the displayed grain and non-grain proportions.

Engineering Contradiction Analysis
1Measurement precision
If a correction factor is determined empirically and stored in memory, then the evaluation device can determine display value proportions, but the correction factor varies depending on the crop and grain sizes, causing deviations from actual conditions
Solution Approach 1:
The correction factor is made dynamically adjustable by the operator during operation. Instead of being a fixed stored value, the operator can modify the correction factor based on actual observations of the crop stream and broken grain proportion in the grain tank, allowing the system to adapt to different crops and field conditions in real-time
Solution Approach 2:
The system implements feedback by comparing the display value broken grain proportion with the actual broken grain proportion observed by the operator in the grain tank. This feedback loop allows the operator to adjust the correction factor to improve accuracy, creating a closed-control system that responds to actual operating conditions
2Measurement precision
If the correction factor is adjusted to improve accuracy, then display values align better with actual conditions, but the operator faces difficulty adjusting abstract numerical values that are hard to relate to actual field conditions
Solution Approach 1:
The display value broken grain proportion acts as an intermediary between the raw image analysis data and the actual physical condition. By adjusting this display value through the correction factor, the operator works with a tangible representation of the actual broken grain proportion in the grain tank, making the adjustment process more intuitive and easier to understand
Solution Approach 2:
The system allows the operator to change the correction factor parameter to transform the raw broken grain proportion into the display value broken grain proportion. This parameter adjustment enables the operator to align the displayed values with actual field conditions, improving both accuracy and operational ease
