Garden Sprinkler Nozzle Control via Integrated Adjusting Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional garden sprinklers require time-consuming and labor-intensive adjustments to achieve evenly distributed water patterns, often resulting in uneven spray due to complex and poorly coordinated adjustment mechanisms.
Innovation Solution
A garden sprinkler with a nozzle control system featuring a main body, adjusting base, and driving member, where the adjusting base is translated by rotating a knob, allowing nozzles to adjust in a single operation to achieve concentrated or fan-shaped patterns with equal density, eliminating the need for complex and imbalanced force applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate adjusting parts are used to control spray direction and density, then the nozzles can be positioned and oriented, but the adjustment process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent combines multiple adjusting parts (first adjusting part for spray direction and second adjusting part for spray density) into a single integrated adjusting mechanism. This allows both the direction and density of the nozzles to be controlled simultaneously through one adjusting operation, eliminating the need for separate adjustments and significantly reducing the time and labor required.
Solution Approach 2:
The adjusting mechanism is designed to perform multiple functions through a single device. The first adjusting part controls both the direction and density of the nozzles, making it a multi-functional component that replaces what would traditionally require separate adjusting mechanisms for each parameter.
2Ease of operation
If multiple separate adjusting parts are used to control spray direction and density, then the nozzles can be positioned and oriented, but the coordination between parts becomes complex and may result in uneven spray distribution
Solution Approach 1:
By merging the adjusting functions into a single integrated mechanism, the patent eliminates the coordination problems between multiple separate parts. The unified adjusting mechanism ensures that changes in spray direction and density are synchronized, maintaining uniform spray distribution while simplifying the adjustment operation.
3Productivity
If a single-stage adjustment mechanism is used, then the nozzles can be adjusted quickly, but achieving equal density spray pattern becomes difficult
Solution Approach 1:
The patent segments the adjusting mechanism into two functional parts within a single-stage operation: the first adjusting part controls spray direction while the second adjusting part controls spray density. This segmentation allows each parameter to be optimized independently while maintaining overall adjustment speed, achieving both quick adjustment and uniform spray density.
Solution Approach 2:
The adjusting mechanism is designed with local quality differentiation where different parts of the single-stage mechanism perform specialized functions. The first adjusting part is optimized for directional control while the second adjusting part is optimized for density control, allowing each to excel at its specific function while working together in one adjustment operation.

Function Achieved in This Case
This design enables quick, labor-saving adjustments that ensure a pattern of equally and densely sprayed water, reducing operational effort and ensuring precise nozzle alignment for efficient water distribution.
Implementation Method 1
a screw is connected to a middle portion of a rear end of the knob. A stop groove is arranged on the screw, being adjacent to the knob

AI summary
A garden sprinkler with nozzle control system comprises a main body (10), a spraying unit (20), at least one adjusting base (30), and at least one driving member (40). The main body (10) has a main base (11) and an upper cover (12) mating with each other, whereas the main base (11) has an assembly opening (111) at an end thereof. The spraying unit (20) is to be put into the main base (11) through the assembly opening (111), and a hose coupling (13) is to be mounted in the assembly opening (111). A recess (112) and a sprinkling surface (113) are formed on the main base (11) downwards in sequence in such a way that the adjusting base (30) can be put in the recess (112), whereas the corresponding middle section of the front and rear sides of the main body (10) is formed in such a way that at least one passageway (14) is being formed by combining the main base (11) and the upper cover (12) with each other. A screw (42) of the driving member (40) is to be inserted into the passageway (14), permitting the driving member (40) to idle on the main body (10), but not to be released from the same.
