Solution Overview

Problem

Existing agricultural harvesting systems rely heavily on operator supervision, which is prone to fatigue and reduces the effectiveness of monitoring crop loss due to operator inattention, especially in large headers where continuous supervision is impractical.

Innovation Solution

A loss monitoring system with transceiver sensors and controllers that identify crop constituents below the header arrangement, determining a loss metric and controlling machine operations to minimize losses, including adjusting skid plates, row unit spacing, and machine speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If operator monitoring of header performance is used, then system complexity is reduced, but measurement precision and reliability of crop loss monitoring deteriorate due to operator fatigue and inattention

Engineering Contradiction:
Improvesystem complexityVSAvoidcrop loss monitoring precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces manual operator monitoring with an automated sensor-based detection system. Transceiver sensors mounted on the header arrangement automatically detect and monitor crop constituents (kernels, cobs, etc.) falling below the header, eliminating the need for continuous human observation and thereby maintaining high measurement precision without operator fatigue.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-monitoring of crop loss by the header arrangement itself through integrated transceiver sensors. The sensors continuously scan the area below the header and automatically identify falling crop constituents, allowing the system to self-assess its performance without external human intervention.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If continuous operator supervision of the full header is implemented, then measurement precision improves, but ease of operation deteriorates due to the extensive time and attention required

Engineering Contradiction:
Improveheader performance monitoring precisionVSAvoidoperator workload
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The automated transceiver sensor system replaces the need for continuous operator supervision. The sensors are mounted on the header and automatically scan the area below, providing continuous monitoring of crop loss without requiring operator attention or manual inspection, thereby maintaining precision while dramatically improving ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sensor system provides continuous, uninterrupted monitoring of crop constituents falling below the header throughout the entire harvesting operation. Unlike periodic manual checks by an operator, the automated system maintains constant surveillance, ensuring no loss events are missed while freeing the operator for other tasks.

Inventive Principle:
Principle #20Continuity of useful action

3Measurement precision

If manual inspection of ground area for crop constituents is performed, then measurement precision is adequate, but loss of time increases due to stopping the machine for inspection

Engineering Contradiction:
Improvecrop loss measurement accuracyVSAvoidharvesting operation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The transceiver sensor system enables continuous monitoring of crop loss without interrupting the harvesting operation. Sensors mounted on the header continuously scan the area below and detect falling constituents in real-time, eliminating the need to stop the machine for ground inspections and thereby preventing any loss of harvesting time while maintaining accurate measurement.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system detects crop constituents as they fall below the header, before they reach the ground. This preliminary detection allows for immediate identification of loss events during the harvesting operation, eliminating the need for subsequent ground inspections and saving the time that would be lost stopping the machine.

Inventive Principle:
Principle #10Preliminary action

4Measurement precision

If automated sensor-based monitoring is implemented, then measurement precision and productivity improve, but device complexity increases due to additional sensors and control systems

Engineering Contradiction:
Improvecrop loss monitoring precisionVSAvoidmonitoring system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The transceiver sensor system is designed to perform multiple functions: detecting crop constituents, identifying their type (kernel, cob, etc.), tracking their movement, and providing data for loss calculation. This multi-functionality consolidates what would otherwise require multiple separate systems into a single integrated solution, managing complexity while maintaining high measurement precision.

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

Solution Approach 2:

The control system acts as an intermediary that processes sensor data and translates it into meaningful loss metrics. Rather than requiring complex direct analysis of raw sensor signals, the control system mediates between the sensors and the operator, filtering and interpreting data to provide clear, actionable information about crop loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems and methods are provided for monitoring crop loss associated with a header arrangement operably couplable to an agricultural harvesting machine. One or more transceiver sensors are coupleable, in use, to the header arrangement and configured, in use, for transmitting measurement signals and receiving reflections thereof from an object within a sensing region of the sensor which at least partly includes a region below the header arrangement. Sensor data therefrom is processed to identify crop constituents present within the sensing region and a loss metric for an agricultural operation performed by the header arrangement is determined in dependence thereon. Operation of operable components of or otherwise associated with the header arrangement and/or the agricultural harvesting machine can be controlled in dependence on the determined loss metric.
