Rotor Nozzle Structure with Stopper for Concentrated Linear Spray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotor nozzle structures in watering devices cause the rotor to rotate, leading to dispersed fluid output, which is undesirable for concentrated spraying.
Innovation Solution
A rotor nozzle structure with a longitudinal chamber and stoppers to prevent rotor rotation, featuring a spherical end connecting to the water outlet and guide members for a tilt arrangement, ensuring the rotor remains stationary and fluid concentrates at the outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conical chamber with an intermediate element is used to accommodate the rotor, then the rotor can rotate to produce a swirling spray pattern, but the fluid output becomes dispersed instead of concentrated
Solution Approach 1:
The invention removes the intermediate element with spherical surface from the conical chamber structure. This extraction eliminates the mechanism that causes rotor rotation and fluid dispersion, allowing the fluid to flow straight through the rotor along the longitudinal axis without being diverted into a swirling pattern, thus achieving concentrated fluid output.
Solution Approach 2:
Instead of using a conical chamber that promotes rotor rotation and fluid dispersion, the invention inverts the approach by using a longitudinal chamber that maintains straight fluid flow. The chamber structure is inverted from a conical shape that encourages rotation to a cylindrical longitudinal shape that preserves linear flow and concentrated output.
2Stability of the object's composition
If a conical chamber with intermediate element is used, then the rotor rotates in the chamber, but this prevents concentrated fluid output
Solution Approach 1:
The intermediate element that causes rotor rotation is completely removed from the chamber structure. This extraction eliminates the interaction between the spherical surface of the intermediate element and the rotor, preventing unwanted rotation and ensuring stable, concentrated fluid output through the rotor.
Solution Approach 2:
The invention applies different local qualities to different parts of the chamber: the longitudinal chamber provides a straight flow path for concentrated output, while the stopper at the water outlet end provides localized positioning for the rotor without causing rotation. This localized functionality achieves both stable positioning and concentrated fluid output.
3Stability of the object's composition
If a stopper is set on the inner side of the chamber near the water outlet, then the rotor is secured in a tilt arrangement, but this requires a new chamber structure instead of conventional conical chamber
Solution Approach 1:
The chamber structure is segmented into functional zones: a longitudinal chamber for straight fluid flow and a stopper component for rotor positioning. This segmentation allows the stopper to provide precise tilt positioning of the rotor while the longitudinal chamber maintains simple, straight geometry, reducing overall structural complexity compared to a complex conical chamber with intermediate elements.
Solution Approach 2:
The stopper provides localized positioning functionality at the water outlet end of the chamber, while the rest of the chamber maintains simple longitudinal geometry. This localized approach achieves precise rotor tilt positioning without requiring complex chamber structures throughout, simplifying the overall device.
