Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine guidance systems are limited in providing detailed guidance for machines with implements, especially in non-roadway applications and varying terrains, and do not account for the operation and actuation of implements, leading to inadequate operational information for operators.
Innovation Solution
A system and method for configuring guidance controllers to detect implements, determine their characteristics, and adjust calibration parameters to control the operational path of machines, incorporating global positioning data and implement-specific information to provide detailed guidance for machines operating in different terrains and with various attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional guidance systems are used for machines with implements, then basic navigation is provided, but detailed operational guidance for implements is not available
Solution Approach 1:
The guidance controller is designed to detect and identify multiple types of implements (planters, sprayers, cultivators, etc.) and automatically configure guidance parameters for each implement type, enabling a single system to provide specialized guidance across diverse agricultural applications
Solution Approach 2:
The system dynamically adjusts calibration parameters including offset distances, heading angles, and guidance settings based on the detected implement characteristics, transforming the guidance controller from a fixed-configuration system to an adaptive one that optimizes parameters for each specific implement
2Measurement precision
If guidance systems are configured for specific implements, then operational precision is improved, but system complexity increases
Solution Approach 1:
The guidance controller automatically detects the implement type through sensor inputs and communication systems, retrieves appropriate calibration parameters from stored data, and configures itself without requiring manual operator input, thereby maintaining high precision while eliminating configuration complexity for the user
Solution Approach 2:
Calibration parameters for multiple implement types are pre-configured and stored in the guidance controller's memory during system setup or manufacturing, allowing the controller to quickly retrieve and apply the correct parameters when an implement is detected, avoiding real-time complex calculations or manual configuration
3Loss of time
If manual configuration of guidance parameters is used, then system simplicity is maintained, but time consumption and operator burden increase
Solution Approach 1:
The system uses sensors and communication systems to detect implement presence and characteristics, providing feedback to the guidance controller which automatically adjusts configuration parameters, creating a closed-loop system that eliminates manual configuration steps and reduces operator burden

AI summary
System and method for configuring guidance controllers. In one embodiment, a method includes detecting an implement, by a guidance controller, coupled to a machine. The method may further include determining a characteristic of the implement which affects a calibration parameter of the guidance controller and configuring the calibration parameter of the guidance controller based, at least in part, on the characteristic of the implement. An operational path of the machine may be controlled based on the calibration parameter.
