Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural balers operate inefficiently due to lack of data on crop material distribution and parameters such as density and moisture, which hinders optimal operation and field management.

Engineering Contradiction Analysis
1Productivity
If traditional balers without sensors are used, then the device complexity is low, but the productivity and operational efficiency are poor due to lack of field condition data
Solution Approach 1:
The controller serves multiple functions: it controls the tailgate operation, processes location sensor data, processes parameter sensor data, determines parameter distributions, updates the field map, and provides operational recommendations. By making the controller multi-functional, the system achieves high productivity without adding separate dedicated devices for each function, thus improving baling efficiency while limiting the increase in device complexity.
Solution Approach 2:
The field map acts as an intermediary data structure that accumulates and organizes information from location and parameter sensors over time. This intermediary allows the system to process field condition data efficiently and generate operational recommendations without requiring complex real-time processing of all sensor data, thereby improving productivity while managing system complexity.
2Loss of information
If no field map updating system is implemented, then the device complexity remains low, but the loss of information about crop material distribution and field conditions occurs
Solution Approach 1:
The system continuously updates the field map during baling operations as location and parameter data become available. This preliminary action of data collection and organization during operation ensures that field condition information is captured and stored before the harvesting season ends, preventing information loss while processing data incrementally rather than requiring complex batch processing.
Solution Approach 2:
The field map creates a digital copy or representation of the physical field's crop material distribution and conditions. This digital copy preserves all measured parameters and location data in an accessible format that can be used for analysis and decision-making, preventing information loss while using relatively simple data storage and retrieval mechanisms.
3Measurement precision
If real-time parameter monitoring is added to improve operational efficiency, then the measurement precision of field conditions improves, but the device complexity increases
Solution Approach 1:
The system measures specific local parameters (weight, moisture, location) at the baler's current position and associates them with corresponding field locations. By focusing measurement precision on locally relevant parameters rather than attempting to measure all possible field conditions, the system achieves high measurement precision for critical parameters while keeping the sensor suite and overall system complexity manageable.

AI summary
An agricultural baler system (100) includes an agricultural baler (112) including: a chassis (125); a bale chamber (128) carried by the chassis (125) and configured to form a bale (130) from crop material; a crop conveyor (126) configured to feed crop material into the bale chamber (128); and a location sensor (140) carried by the chassis (125) and configured to output a location signal corresponding to a location of the agricultural baler (112). A parameter sensor (150) is carried by the chassis (125) and configured to output a parameter signal corresponding to a measured parameter and a controller (212) is operably coupled to the location sensor (140) and the parameter sensor (150). The controller (212) is configured to: determine an area based at least partially on a rake width (W) of a rake (310) and a defined length (L); determine a parameter distribution in a region (301A, 301B, 301C, 301D) of a field having the area based at least partially on the measured parameter and the location of the agricultural baler (112); and output a field map update signal to update a field map (300) to indicate the determined parameter distribution.
