Agricultural Machine Navigation via Optical Coordinate Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural work machines lack integrated navigation devices, requiring drivers to manually input GPS coordinates, which is time-consuming and prone to errors, especially for new or temporary drivers.
Innovation Solution
The agricultural work machine provides an optical pattern with navigation information, which can include GPS coordinates, that a mobile navigation device can read optically, initiating a navigation routine to the target location with reduced time and error susceptibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS coordinates are manually entered into a mobile navigation device, then navigation functionality is achieved, but time expenditure increases and error susceptibility increases
Solution Approach 1:
The patent replaces the mechanical manual input process with an optical reading system. The mobile navigation device uses its camera to optically capture and automatically read GPS coordinates displayed on the agricultural machine's display, eliminating the need for manual keyboard or touchscreen input and thereby reducing both time expenditure and error susceptibility.
Solution Approach 2:
The patent creates an optical copy of the navigation information by displaying GPS coordinates on the agricultural machine's display and having the mobile device capture this visual representation through its camera. This optical copying process enables automatic data transfer without manual intervention.
2Productivity
If GPS coordinates are manually entered into a mobile navigation device, then navigation functionality is achieved, but error susceptibility increases
Solution Approach 1:
The patent replaces the error-prone manual input mechanism with an automated optical recognition system. The mobile device's camera captures the displayed coordinates and automatically processes them, eliminating human errors in transcription and entry while improving both productivity and reliability.
Solution Approach 2:
The system enables self-service navigation setup where the mobile device automatically reads and processes the GPS coordinates displayed on the agricultural machine without requiring manual intervention. This self-reading capability reduces errors and improves work efficiency.
3Loss of time
If optical pattern with navigation information is provided by the agricultural work machine, then time expenditure is reduced and error susceptibility is reduced, but additional system components are required
Solution Approach 1:
The patent utilizes the existing display component of the agricultural machine for dual purposes: displaying operational information and displaying GPS coordinates for navigation. The mobile device's camera, already present for other functions, is used to capture the coordinates. This multi-functionality approach reduces the need for additional dedicated components while achieving automatic navigation setup.
