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.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvebaling efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvefield condition dataVSAvoiddata processing system
Core Design Contradiction:
Loss of informationVSDevice complexity

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #26Copying

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

Engineering Contradiction:
Improvefield condition measurementVSAvoidsensor and control system
Core Design Contradiction:
Measurement precisionVSDevice complexity

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.

Inventive Principle:
Principle #3Local quality

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.
