Irrigation Sprinkler Nozzle Deflector Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional irrigation sprinkler devices often result in non-uniform water distribution, leading to overwatering in some areas and underwatering in others, due to lower Distribution Uniformity (DU) and Scheduling Coefficient (SC) values, which complicates irrigation scheduling and efficiency.
Innovation Solution
The use of spray nozzles with adjustable arcuate discharge openings and deflectors featuring depending ribs with micro-structures that redirect water into different sprays with varying characteristics, improving DUlq and SC values by segregating water flow into tailored sprays for more efficient irrigation patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional spray nozzle irrigation devices are used, then the device structure is simple, but the water distribution uniformity is poor resulting in lower DUlq values
Solution Approach 1:
The deflector is segmented into multiple radially outward extending ribs that create separate channels for water flow. Each rib with its micro-ramp structure independently directs a portion of the water flow, dividing the single water stream into multiple controlled sprays. This segmentation enables precise control over water distribution patterns and improves uniformity across the irrigation area.
Solution Approach 2:
The deflector incorporates micro-ramps at specific locations on the ribs, creating localized flow modification zones. These micro-ramps are positioned to specific heights and angles to control the direction and characteristics of water sprays in different radial zones. This local quality approach allows tailored spray characteristics in different areas to achieve optimal water distribution uniformity.
2Productivity
If conventional spray nozzles are used, then the device complexity is low, but the scheduling coefficient is high requiring extra watering time
Solution Approach 1:
The deflector structure segments water flow into multiple controlled channels using radially extending ribs with micro-ramps. This segmentation creates predictable spray patterns that improve water distribution uniformity, directly reducing the scheduling coefficient by ensuring all areas receive adequate water simultaneously, thereby improving irrigation efficiency.
Solution Approach 2:
The micro-ramp height, angle, and positioning are carefully controlled parameters that modify water flow characteristics. By optimizing these parameters, the spray pattern is tuned to achieve better water distribution uniformity, which reduces the scheduling coefficient and eliminates the need for extended irrigation times to cover critical dry areas.
3Manufacturing precision
If water is applied to ensure critical areas receive minimum water, then the scheduling coefficient is addressed, but overwatering occurs in other areas
Solution Approach 1:
The micro-ramps on the ribs create localized spray control zones that deliver water precisely where needed. Each rib-micro-ramp combination is configured to direct water to specific areas, ensuring critical zones receive adequate water without requiring excessive application to non-critical areas. This local quality control eliminates overwatering while meeting minimum requirements for all areas.
Solution Approach 2:
The segmented deflector structure with multiple ribs and micro-ramps divides water flow into distinct sprays targeting different zones. This segmentation enables precise water application to critical areas while controlling or eliminating water application to areas that do not require additional water, thereby preventing water waste through overwatering.
