Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprinklers lack the ability to create a vortex-like circular motion with the water jet, limiting the versatility and efficiency of water distribution.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional sprinklers spray water in a straight path, then the structure is simple, but the water distribution versatility is limited
Solution Approach 1:
The patent applies the dynamics principle by making the rotating body capable of rotation about its own axis while simultaneously performing vortex-like circular motion around the first axis line. This dynamic motion transforms the water spray from a straight path into a spiral pattern, significantly improving water distribution versatility without requiring multiple separate sprinkler units
Solution Approach 2:
The patent utilizes hydraulic principles by designing the flow guiding passage with an oblique second axis line that intersects the first axis line, and the conical flow converging passage that guides water flow to generate rotational motion. The water pressure and flow dynamics naturally induce the vortex-like circular motion, achieving complex spray patterns through fluid mechanics rather than complex mechanical mechanisms
2Productivity
If a rotary sprinkler head with vortex motion is implemented, then water distribution efficiency increases, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single rotating body: it combines the rotation about its own axis with the vortex-like circular motion around the first axis line. The flow guiding passage and conical flow converging passage are integrated into the rotating body structure, allowing one component to perform multiple functions that would otherwise require separate mechanisms
Solution Approach 2:
The rotating body serves multiple purposes: it guides water flow through the oblique flow guiding passage, concentrates flow through the conical flow converging passage, generates rotational motion, and simultaneously performs vortex-like circular motion. This multi-functionality improves water distribution efficiency while minimizing the number of separate components needed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a vortex-like circular motion, resulting in a spiral-shaped water spray pattern that increases distribution efficiency and versatility.
Implementation Method 1
the rotating body not only rotates on its own axis but also performs a vortex-like circular motion with the first axis line as the center, forming a motion similar to a revolution
Implementation Method 2
A conical flow converging passage penetrates the interior of the convergent segment along its axis to connect the flow guiding passage and the second space

AI summary
Disclosed is arotary sprinkler head and a spraying device including the same. The rotary sprinkler head has a shell-shaped main body, a rotating body, and a limiting member. The interior of the main body forms a chamber which accommodates the rotating body and is delimited by the limiting member. A water outlet passage is connected to the chamber through one end of the main body. The rotating body features an abutting segment, and a flow guiding passage extends through the abutting segment to connect with the water outlet passage. This flow guiding passage is obliquely oriented relative to the axis of the chamber, thereby allowing the water to enter a second space, then divide into flows through a first space and the flow guiding passage, causing the rotating body to rotate about its own axis and perform a vortex-like circular motion.
