Display Control Device for Harvester Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of harvesting machines face challenges in adjusting control parameters to achieve optimal performance, as existing methods can lead to unsuitable interventions during automatic optimization processes, causing fluctuations in displayed work result values that may prompt incorrect adjustments.
Innovation Solution
A display management system that suppresses or marks as invalid the current work result values influenced by control parameters during optimization, using a display control device with signal inputs and a graphics module to prevent unwanted operator interventions by hiding or weakening the display of relevant work result values.

Engineering Contradiction Analysis
1Extent of automation
If automatic optimization processes vary control parameters to determine optimal settings, then the system can automatically adapt to harvesting conditions, but the displayed work result values fluctuate causing operators to make unwanted manual adjustments
Solution Approach 1:
The patent applies visual differentiation by changing the display appearance of work result values during optimization processes. Specifically, affected work result values are displayed in a differentiated manner (e.g., different color, intensity, or visual marking) to indicate they are currently influenced by automatic parameter variation. This allows operators to distinguish between values that are actively being optimized and those that are stable, preventing unwanted manual interventions during the automatic optimization process.
2Loss of information
If all work result values are continuously displayed to inform the operator, then the operator has complete information, but the operator may react to temporary fluctuations during optimization and make incorrect adjustments
Solution Approach 1:
The patent applies local quality differentiation by treating different work result values differently based on their current state. Work result values that are influenced by ongoing optimization processes are displayed with differentiated visual characteristics (such as different color intensity, shading, or symbolic marking), while unaffected values are displayed in the normal manner. This localized visual differentiation allows the operator to maintain complete information access while easily identifying which values should not trigger manual adjustments.
3Manufacturing precision
If control parameters are varied to test different settings during optimization, then optimal settings can be determined, but the optimization process takes time and reduces productivity
Solution Approach 1:
The patent implements preliminary action by performing automatic optimization processes during periods when harvesting speed can be temporarily reduced without significant impact on overall productivity. The system is designed to conduct parameter variation and optimization testing during natural breaks in the harvesting workflow or during less critical periods, thereby achieving precise setting optimization while minimizing disruption to the overall harvesting productivity.

AI summary
The method involves indicating multiple result values (AV,RV,VU,KU) for a user of the harvester on the display device (20). During optimization process different settings of control parameter of operating aggregates of the harvester are rounded up temporarily for determining a target setting value of the control parameter automatically in a harvesting process. The display is disabled form such active result values or is marked as invalid, which are affected by the control parameter. Independent claims are also included for the following: (1) a display control device for controlling display device (2) a harvester with a display device.
