Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional irrigation systems face inefficiencies in water distribution, leading to wasted water due to inconsistent coverage, runoff, and uneven irrigation, especially in irregularly shaped areas, resulting in higher costs and soil maintenance issues from mineral deposits.
Innovation Solution
An automated irrigation system with a housing, nozzle, and movers that rotate and oscillate based on fluid pressure and area positioning, allowing precise irrigation distribution by axis rotation and oscillation, and wind direction, to target specific areas effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional irrigation units distribute water in full round, half-round, quarter-round or adjustable-type circular patterns, then the irrigation units can cover a circular area, but consistent water coverage over a rectangular watering area is difficult or impossible
Solution Approach 1:
The irrigation system employs a movable nozzle that can dynamically change its orientation and spraying direction. The nozzle is mounted on a cart with wheels and can be rotated to different angles, allowing the system to adapt to various area shapes (rectangular, circular, irregular) while maintaining consistent water coverage. This dynamic positioning capability resolves the contradiction between coverage consistency and shape adaptability.
Solution Approach 2:
The system changes the parameter of nozzle orientation angle to adapt to different watering area shapes. By adjusting the nozzle's angular position and spraying direction, the system can effectively water rectangular, circular, or irregular areas while maintaining uniform water distribution. This parameter adjustment resolves the contradiction between consistent coverage and shape versatility.
2Reliability
If irrigation units are arranged to ensure all areas are adequately irrigated, then adequate irrigation coverage is achieved, but overlapping spray regions occur resulting in certain areas receiving 300% or more of the necessary amount of water
Solution Approach 1:
The system incorporates sensors (such as moisture sensors, flow sensors, or position sensors) that provide feedback on water distribution status and nozzle positioning. This feedback mechanism allows the system to adjust the nozzle's spraying direction, movement speed, and water flow rate in real-time to achieve uniform water distribution and prevent overlapping spray regions. The feedback control resolves the contradiction between adequate irrigation coverage and water waste prevention.
Solution Approach 2:
The movable nozzle system dynamically adjusts its position and spraying parameters based on real-time conditions. By continuously moving and repositioning the nozzle rather than using fixed multiple nozzles, the system can provide adequate coverage without creating overlapping spray regions that waste water. The dynamic operation enables precise control over water distribution patterns.
3Reliability
If water is applied to prevent brown spots, then vegetation browning is prevented, but over watering occurs in basically all other areas
Solution Approach 1:
The system applies water with local quality control by directing water precisely to specific areas that need it. The movable nozzle can target individual zones or spots requiring irrigation based on vegetation condition, soil moisture levels, or pre-programmed patterns. This localized water application ensures vegetation health is maintained while preventing excessive water application in areas that already have sufficient moisture.
Solution Approach 2:
Moisture sensors or soil sensors provide feedback on the actual water needs of different areas. The system uses this feedback to adjust water application rates and durations locally, ensuring that water is applied only where and when needed to prevent browning. This feedback mechanism eliminates the need for blanket over-watering approaches.
4Ease of operation
If runoff from elevated areas such as mounds, slopes or hills causes ponding in lower areas, then higher areas can be irrigated, but lower areas are saturated with water
Solution Approach 1:
The movable nozzle system can dynamically adjust its position and spraying angle to account for terrain variations. When operating on elevated areas like slopes or mounds, the system can modify its water application rate and direction to prevent runoff to lower areas. This dynamic adjustment maintains uniform water distribution across varied terrain without causing saturation in lower areas.
Solution Approach 2:
The system changes water application parameters (flow rate, pressure, spray pattern) based on terrain elevation and slope. On elevated areas, the system reduces water application rate or adjusts spray direction to prevent runoff, while on lower areas it may increase application carefully to avoid saturation. These parameter adjustments resolve the contradiction between ease of operation on varied terrain and uniform water distribution reliability.

AI summary
An irrigation unit (10) includes a housing (200), a nozzle (220), a first mover (238) and a second mover (268). The nozzle (220) is secured to the housing (200) and is in fluid communication with a fluid source (18). The first mover (238) rotates the nozzle (220) about a first axis, and the second mover (268) rotates the nozzle (220) about a second axis that is different than the first axis. In one embodiment, the second axis is substantially perpendicular to the first axis. At least a portion of the housing (200) can movably extend along the first axis. The second mover (268) can rotate the nozzle (220) about the second axis based upon a pressure of a fluid (19) within the housing (200) and/or upon position of an area (30) relative to the nozzle (220). Further, the second mover (268) can oscillate the nozzle (220) about the second axis. The rotation of the nozzle (220) about the second axis can also be based upon at least one of a wind direction and a wind speed near the nozzle (220).
