Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems with multiple self-propelled tillage implements struggle to coordinate their activities effectively, leading to user disturbance and inefficiencies in energy and time usage, as it is unclear when each device completes its tasks, resulting in uncomfortable situations and suboptimal processing.
Innovation Solution
The system tracks and stores the movement route and time of each tillage implement, subdivides the environment into sub-area groups, and assigns these groups to devices based on their processing capabilities, ensuring that sub-area groups are completed simultaneously by adjusting for differences in travel speed and processing times, thereby minimizing wait times for users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple self-propelled tillage implements work independently without coordinated task assignment, then each device can operate autonomously, but user disturbance increases and energy/time efficiency decreases due to uncoordinated completion times
Solution Approach 1:
The environment map is divided into multiple sub-areas, which are then grouped into sub-area groups and assigned to different tillage implements. This segmentation allows independent operation of each device while coordinating their completion times through centralized task distribution based on detected movement routes and processing speeds.
2Device complexity
If sub-areas are assigned to tillage implements without considering movement speed and processing time, then task distribution is simple, but completion times vary significantly causing user disturbance
Solution Approach 1:
The system detects and stores the actual movement route and movement time of tillage implements during environmental mapping. This feedback information is used to calculate processing speeds and adjust task assignments accordingly, ensuring that implements with different speeds receive appropriately sized sub-area groups to achieve simultaneous completion.
3Measurement precision
If the environmental map is divided into many small sub-areas for precise task assignment, then task allocation accuracy improves, but system complexity and computational requirements increase
Solution Approach 1:
The environment map is divided into sub-areas that are then clustered into sub-area groups. This hierarchical segmentation provides sufficient precision for task assignment while reducing the computational complexity of managing individually tiny sub-areas, as implements are assigned groups rather than individual small units.
4Ease of operation
If tillage implements operate without coordinated task assignment based on detected capabilities, then system operation is simple, but energy efficiency and productivity are suboptimal
Solution Approach 1:
The system dynamically adjusts task assignment parameters based on detected movement routes, movement times, and processing speeds of individual implements. By changing assignment parameters according to actual device capabilities rather than using fixed allocations, the system maintains operational simplicity while significantly improving productivity and energy efficiency.

AI summary
The invention relates to a method for operating a system with at least two soil cultivation implements (1, 2), wherein at least one detects environmental features of an environment and creates an environmental map (3) based on the detected environmental features, wherein the environmental map (3) is divided into sub-areas (10 - 19) and the sub-areas (10 - 19) are assigned to the soil cultivation implements (1, 2) in such a way that each sub-area (10 - 19) is worked by only one of the soil cultivation implements (1, 2).To achieve efficient environmental processing, it is proposed that a movement route (25) of the soil cultivation implement (1, 2) tracked during the detection of environmental features, as well as a movement time elapsed during movement along the movement route (25), be detected and stored with the environmental map (3), wherein several sub-areas (10-19) are grouped into sub-area groups (4-7), and wherein the assignment of the sub-areas (10-19) to the soil cultivation implements (1, 2) is carried out taking into account the stored movement route (25) and movement time such that soil cultivation of a first sub-area group (4-7) by a first soil cultivation implement (1) is completed essentially simultaneously with soil cultivation of a second sub-area group (4-7) by a second soil cultivation implement (1).
