Dual GPS Tracking System for Implement Parameter Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracking systems for work machines struggle to accurately and conveniently determine implement-related parameters, such as the distance between the hitch point and the implement-mounted GPS receiver, due to variability in soil conditions and implement weight, leading to inaccurate manual measurements by operators.
Innovation Solution
A tracking system employing two GPS receivers, one on the work machine and one on the implement, along with a controller that determines these parameters by obtaining position data from both receivers and correcting for terrain effects using roll, pitch, and yaw data from terrain compensation modules, allowing for automatic calculation of distances and control points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual measurement is used to determine implement-related parameters, then the operator can obtain the parameters, but the accuracy of the parameters deteriorates due to variability in soil conditions and implement weight
Solution Approach 1:
The patent replaces manual mechanical measurement with an automated electronic system using GPS receivers and terrain compensation modules. The system automatically calculates implement parameters by processing position data from GPS receivers and terrain data from compensation modules, eliminating the need for manual measurement while improving accuracy despite variations in soil conditions and implement weight.
Solution Approach 2:
The system enables self-service by automatically determining implement-related parameters without requiring operator intervention for measurement. The GPS receivers and terrain compensation modules work autonomously to collect data and calculate parameters, allowing the system to self-correct for terrain effects and implement variations.
2Device complexity
If manual measurement is used to determine implement-related parameters, then the process is simple, but the time required for accurate measurement increases due to the need for multiple measurements under different conditions
Solution Approach 1:
The patent implements continuous data collection and processing by the GPS receivers and terrain compensation modules during implement operation. Instead of requiring separate measurement sessions under different soil conditions, the system continuously monitors position and terrain data, automatically calculating parameters in real-time or near-real-time, thus eliminating time loss while maintaining process simplicity.
3Measurement precision
If GPS receivers are mounted on both the work machine and implement with automatic parameter determination, then the accuracy of parameter determination improves, but the device complexity increases
Solution Approach 1:
The patent applies universality by using multi-functional components that serve multiple purposes. The GPS receivers not only provide position data but also contribute to parameter calculation. The terrain compensation modules serve both to correct position accuracy and to provide terrain data for parameter determination. This multi-functionality reduces the need for separate dedicated components, thereby managing complexity while maintaining high measurement precision.
