Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural particle distribution systems, such as those for solid fertilizers and seeds, face challenges in optimizing distribution at field edges and tips, requiring significant driver experience and often resulting in inaccuracies, overdoses, and underdoses, which are costly and environmentally harmful.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of distribution is used, then driver experience can optimize spreading, but distribution accuracy deteriorates due to judgment errors and lack of precision
Solution Approach 1:
The patent replaces manual mechanical control with an automated electronic control system that uses GPS geolocation signals to trigger distribution device operations. This substitution eliminates human judgment errors while maintaining operational simplicity through automatic activation and deactivation based on predefined geographic boundaries.
Solution Approach 2:
The system enables self-service operation where the distribution device automatically activates and deactivates based on its own geolocation positioning relative to stored field boundary coordinates. The device monitors its own position and autonomously controls distribution without requiring continuous manual intervention, improving both accuracy and operational ease.
2Manufacturing precision
If automated GPS control is implemented, then distribution accuracy improves, but device complexity increases due to specific control means
Solution Approach 1:
The patent employs a universal GPS receiver and control module that can be integrated with various types of distribution devices (spreaders, seeders, fertilizers). The same geolocation-based control system serves multiple functions including boundary detection, activation/deactivation control, and positioning monitoring, reducing overall system complexity while maintaining high distribution accuracy.
Solution Approach 2:
The system merges the GPS navigation function with the distribution control function into a single integrated control unit. By combining geolocation signal reception, boundary comparison logic, and distribution device actuation control into one unified system, the patent reduces the number of separate components while achieving precise automated distribution control.
3Manufacturing precision
If distribution is interrupted at field edges, then distribution accuracy improves, but productivity decreases due to frequent start-stop operations
Solution Approach 1:
The system performs preliminary action by pre-storing the geographic boundary coordinates of the field in memory before operation. This allows the distribution device to anticipate when to activate or deactivate based on approaching boundary points, enabling smoother transitions and reducing abrupt start-stop operations that would otherwise reduce productivity.
Solution Approach 2:
The patent maintains continuity of useful action by keeping the distribution device in a ready state with continuous GPS monitoring. The system continuously tracks position relative to stored boundaries and maintains optimal distribution parameters throughout the field, minimizing interruptions while ensuring homogeneous distribution through continuous automated adjustment rather than frequent complete stop-start cycles.

AI summary
The system has a particle distribution controlling autonomous module (35) for controlling opening and closing operations of a particle supplying device. The module includes a reception unit for receiving opening and/or closing control signals delivered by a guide bar (32). The module includes a conversion unit for converting the control signals into opening and/or closing commands of actuators (36-1, 36-2) such that the actuators are controlled by the control signals generated by the guide bar. An independent claim is also included for a method for automatic distribution of particles for an agricultural machine.
