Agricultural Mower Interface Dynamic Overlap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing human-machine interfaces for agricultural implements, such as those with a front mower and rear mowers, lack an efficient method for adjusting the overlap between the mowing areas, particularly when operating on slopes or corners, leading to difficulties in maintaining optimal coverage.
Innovation Solution
A novel human-machine interface with individual input keys for each rear mower and a common input button for symmetrical or asymmetrical overlap settings, allowing automatic adjustment of the overlap between the maximum and minimum permissible values, enabling easy, reliable, and effective adjustment of the mowing coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional human-machine interface with pre-assigned softkey input keys is used, then the interface structure is simple, but the overlap adjustment is inconvenient and time-consuming
Solution Approach 1:
The patent implements dynamic adjustment of overlap values through continuous input key pressing. The overlap value changes dynamically based on the duration of the press, allowing operators to quickly adjust between minimum and maximum overlap values without navigating through multiple menus or pressing multiple keys sequentially.
Solution Approach 2:
The system pre-configures minimum and maximum overlap limit values in the control system. When the operator presses the input key, the system automatically selects and applies the appropriate limit value based on the pressing duration, eliminating the need for manual configuration of each overlap setting.
2Manufacturing precision
If manual adjustment of overlap settings is used for each rear mower, then the interface complexity is low, but the adjustment precision and reliability are insufficient for varying operating conditions
Solution Approach 1:
The system automatically determines the appropriate overlap value based on the pressing duration of the input key. The control system self-adjusts the overlap settings without requiring manual intervention for each specific value, improving precision while keeping the interface simple.
Solution Approach 2:
The system provides visual feedback on the operator terminal displaying the current overlap value and its relationship to the minimum and maximum limit values. This feedback mechanism ensures precise control while maintaining interface simplicity through intuitive display.
3Adaptability or versatility
If fixed overlap settings are used, then the control system is simple, but the adaptability to different operating situations (slopes, corners, straight ahead) is poor
Solution Approach 1:
The overlap settings are made dynamic rather than fixed. The system can adapt the overlap values in real-time based on operating conditions by allowing continuous adjustment through the input key pressing mechanism, enabling adaptation to slopes, corners, and straight-ahead operations.
Solution Approach 2:
The system changes the overlap parameter values based on operational needs. By adjusting the overlap between minimum and maximum limit values, the system adapts to different mowing scenarios such as slope compensation, cornering, and straight-line mowing without requiring complex reconfiguration.

AI summary
Human-machine interface (10) for an agricultural implement (1), wherein the implement (1) comprises a towing vehicle (2), a front mower (3) coupled to the towing vehicle (2) and at least one rear mower (4, 5) coupled to the towing vehicle (1), and wherein the human-machine interface (10) has input keys (12, 13, 14), and wherein an overlap or overlap with the front mower (3) can be set via at least one of the input keys for the rear mower or each rear mower (4, 5) between a first limit value corresponding to a maximum permissible overlap and a second limit value corresponding to a minimum permissible overlap.Once the first limit value, and thus the maximum permissible overlap, has been set for the respective rear mower (4, 5), the second limit value, and thus the minimum permissible overlap, is automatically set for the respective rear mower (4, 5) by briefly pressing the respective input key (12, 13, 14). Then, once the second limit value, and thus the minimum permissible overlap, has been set for the respective rear mower (4, 5), the first limit value, and thus the maximum permissible overlap, is automatically set for the respective rear mower (4, 6) by briefly pressing the respective input key (12, 13, 14).Then, if the first or second limit value is set for the respective rear mower (4, 5), a continuous press of the respective input key (12, 13, 14) for the respective rear mower (4, 5) automatically sets an overlap between the first and second limit values, depending on the duration of the continuous press. Then, if an overlap between the first and second limit values is set for the respective rear mower (4, 5), a partial press of the respective input key (12, 13, 14) for the respective rear mower (4, 5) automatically sets the first limit value and thus the maximum permissible overlap.
