Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprinkler heads lack the ability to provide a highly randomized fluid distribution pattern and adequate control over the distribution process, which limits their efficiency in irrigation applications.
Innovation Solution
A sprinkler head design featuring a distribution disk that rotates on two axes, utilizing dampeners and geared teeth to control the speed and direction of rotation, allowing for both rotational and nutational movement, thereby creating a more randomized distribution pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional single-axis sprinkler head is used, then the structure is simple, but the fluid distribution pattern is not randomized enough and irrigation efficiency is limited
Solution Approach 1:
The patent applies dimensionality change by transitioning from a single-axis rotation system to a dual-axis rotation system. The distribution disk rotates on a first axis while simultaneously rotating on a second axis that is perpendicular to the first axis, creating a three-dimensional motion pattern that significantly randomizes fluid distribution. This dual-axis configuration directly addresses the limitation of traditional single-axis sprinklers by adding another dimension of motion without excessive structural complexity.
Solution Approach 2:
The patent implements dynamics by making the distribution disk capable of simultaneous rotation on two different axes, creating a dynamic and randomized fluid distribution pattern. The distribution disk is mounted to rotate on a first axis and also rotate on a second axis perpendicular to the first axis, allowing the sprinkler to adapt its distribution pattern continuously rather than following a fixed single-axis trajectory.
2Productivity
If a distribution disk with two axes of rotation is implemented, then fluid distribution randomness is improved, but the device complexity increases
Solution Approach 1:
The patent applies the nesting principle by placing the upper axle housing inside the lower axle housing, with the upper axle housing rotating on the lower axle. This nested configuration allows the dual-axis rotation system to be compact and integrated, reducing overall device complexity while maintaining the productivity benefits of randomized fluid distribution for improved irrigation efficiency.
Solution Approach 2:
The distribution disk serves multiple functions: it distributes fluid through its nozzles, rotates on the first axis to create distribution patterns, and simultaneously rotates on the second axis to randomize the pattern further. This multi-functionality improves irrigation efficiency without requiring separate components for each function, thereby limiting the increase in device complexity.
3Ease of operation
If dampeners are added to control rotation speed, then control over distribution is improved, but the device complexity increases
Solution Approach 1:
The dampener is configured to be engaged or disengaged by the rotation of the distribution disk itself or associated components, allowing the system to self-regulate its rotation speed without requiring external control mechanisms. This self-service approach improves ease of operation by providing automatic rotation speed control while minimizing the increase in device complexity, as the dampener mechanism is integrated into the existing rotation system rather than adding separate control systems.

Function Achieved in This Case
The two-axis rotation system enhances the distribution pattern randomness and control, improving irrigation efficiency by ensuring uniform water distribution and adaptability.
Implementation Method 1
The dampener is positioned within the upper axle housing such that the dampener controls the speed of rotation of the upper axle housing
Data Source
AI summary
What is disclosed is a sprinkler head having a nozzle configured for spraying a fluid, such as irrigation water, at a distribution disk. The distribution disk is configured to rotate on an upper axle. The upper axle is housed within an upper axle housing. The upper axle housing is configured to rotate about a lower axle. The dual axle provides for two different rotation axles of the distribution disk in operation. Preferably a speed control device can be positioned to control the speed of rotation of one axle or both axles.
