Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural product delivery systems with mid-implement mounted booms face challenges in achieving complete coverage, leading to product loss due to premature activation or deactivation of booms when transitioning between applied and uncovered areas.
Innovation Solution
The system incorporates a pneumatic conveying system with multiple offset booms, a metering system, and a controller to manage airflow and product distribution, allowing individual control of air pressure and metering devices for each boom line to ensure consistent and efficient application across the field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a secondary offset boom is added to compensate for coverage gaps behind the vehicle, then complete coverage is achieved, but product loss increases due to premature activation or deactivation of booms
Solution Approach 1:
The system divides the boom structure into multiple independent segments (primary boom and secondary offset boom) that can be controlled separately. Each boom has its own metering device and air pressure control, allowing independent activation and deactivation to achieve complete coverage without product loss in transition zones.
Solution Approach 2:
The system dynamically controls the activation and deactivation of different boom segments based on real-time positioning and coverage status. The controller adjusts which booms are active at any given moment to ensure complete coverage while avoiding premature activation or deactivation that would cause product loss.
2Productivity
If booms are controlled to turn on and off to manage coverage transitions, then coverage efficiency improves, but product loss occurs due to timing issues in activation and deactivation
Solution Approach 1:
The controller pre-plans the activation and deactivation timing of each boom segment based on vehicle position and coverage requirements. By calculating optimal switch-over points in advance, the system ensures smooth transitions between booms without premature activation or deactivation that would cause product loss.
Solution Approach 2:
The system uses real-time feedback from GPS positioning and coverage monitoring to dynamically adjust boom activation timing. The controller continuously monitors which areas have been covered and adjusts the switch-over timing between booms to maintain complete coverage efficiency while preventing product loss in transition zones.
3Area of stationary object
If multiple offset booms are used to achieve complete coverage, then coverage completeness improves, but system complexity increases due to multiple delivery lines and control mechanisms
Solution Approach 1:
The system uses a universal controller that manages multiple booms and delivery lines through a single integrated control platform. This multi-functional controller handles positioning, coverage monitoring, and coordinated activation/deactivation of all boom segments, reducing operational complexity despite the increased number of physical components.
Solution Approach 2:
The system combines multiple delivery lines and metering devices under a single unified control system that coordinates their operation. By merging the control functions for all booms into one integrated platform, the system manages complexity while maintaining complete coverage capability through coordinated operation of multiple segments.
