Adjustable Liquid Outlet Positioning for Agricultural Spray Tubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural liquid dispensing systems lack adaptability to different plant species and terrain, with fixed application heights and limited variability in dispensing positions, making them prone to damage and inefficient in treating uneven terrains.
Innovation Solution
A device with a tubular body and adjustable outlet device that can be positioned along its length and height, allowing for flexible attachment to machines, featuring a flexible hose and spring device for positioning, and a clamping mechanism for secure attachment, enabling variable dispensing heights and angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outlet device is fixed at a single position on the tubular body, then the structure is simple and robust, but the adaptability to different plant species and dispensing positions is limited
Solution Approach 1:
The outlet device is made adjustable along the longitudinal direction of the tubular body, allowing it to be positioned at different locations. This dynamic positioning capability enables adaptation to different plant species and dispensing requirements without increasing overall device complexity, as the adjustment mechanism integrates seamlessly with the tubular structure.
Solution Approach 2:
The tubular body with adjustable outlet device serves multiple functions: it can dispense liquid at various heights and positions to treat different plant types (stem, leaves, etc.), and the same basic structure can be used across different agricultural applications by simply repositioning the outlet device rather than requiring different specialized equipment for each plant type.
2Adaptability or versatility
If the outlet device is attached to the end of the tubular body, then the structure is simple, but the application height cannot be adjusted
Solution Approach 1:
The outlet device can be positioned at multiple locations along the longitudinal direction of the tubular body, enabling adjustment of application height. This dynamic positioning allows operators to select the appropriate dispensing height for different agricultural needs while maintaining simple attachment and adjustment operations.
3Reliability
If the dispensing system is made robust for impassable terrain, then the reliability increases, but the flexibility in positioning and adapting to different terrains decreases
Solution Approach 1:
The dispensing system is divided into separable components: the tubular body and the outlet device can be detached from each other. This segmentation allows the robust tubular body to withstand harsh terrain conditions while the outlet device can be easily repositioned or replaced to adapt to different positioning requirements and terrain types.
Solution Approach 2:
The detachable connection between the tubular body and outlet device enables dynamic reconfiguration of the system. In impassable terrain, the robust tubular body provides reliability, while the outlet device can be adjusted to different positions along the tubular body or removed entirely if needed, providing flexibility without compromising the structural integrity of the main system.
