Solution Overview
Problem
Existing sprinklers have high production and assembly costs due to model-specific components, leading to increased costs and reduced precision in assembly processes, and lack a simple, easy-to-use design for continuous water adjustment.
Innovation Solution
A sprinkler design featuring a handle, nozzle, tube, valve, and switch with a rotating gate and arched fin mechanism that allows for continuous adjustment of water flow, enabling precise control and easy assembly across different models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If model-specific valves and buttons/levers/switches are used, then the sprinkler can be operated, but the production cost and assembly cost increase
Solution Approach 1:
The patent applies universality by designing a standardized valve body and actuator assembly that can be used across different sprinkler models. The valve body includes a standardized body cavity and sealing member configuration that accommodates various sprinkler types, eliminating the need for model-specific components. This standardized design reduces production costs while maintaining operational reliability through consistent sealing and control mechanisms.
2Reliability
If model-specific valves and buttons/levers/switches are used, then the sprinkler can be operated, but the assembly cost increases
Solution Approach 1:
The patent implements universality by creating a standardized valve assembly with consistent mounting features, sealing configurations, and actuator interfaces across different sprinkler models. This standardization simplifies the assembly process by reducing the variety of assembly procedures needed, while maintaining reliable operational control through proven design elements.
3Adaptability or versatility
If different assembly processes are used for different sprinkler models, then each model can be assembled, but assembly precision decreases
Solution Approach 1:
The patent achieves both adaptability and precision by designing a universal valve assembly that maintains consistent critical dimensions and tolerances across all applications. The standardized body cavity, sealing member, and actuator interface ensure precise assembly regardless of the sprinkler model, while the modular design allows adaptation to different models through consistent mounting provisions.
4Ease of operation
If the button/lever/switch sticks out of the handle, then it can be operated, but it can be operated by mistake
Solution Approach 1:
The patent applies the nesting principle by designing the actuator assembly to be received within a recess of the handle rather than protruding from it. The actuator button is positioned in a recess that provides physical protection against accidental activation, while still allowing intentional operation. This nested configuration maintains ease of operation for deliberate use while preventing inadvertent activation during handling or storage.
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 provides a cost-effective, easy-to-assemble, and reliable sprinkler with continuous water flow adjustment, enhancing user experience and reducing production costs by standardizing components and improving assembly precision.
Implementation Method 1
The valve includes a gate, a positioning portion formed on the gate, and a connective portion formed on the positioning portion. The valve is rotationally inserted in the main channel
Implementation Method 2
The switch includes an arched wall, a fin formed on an arched face of the wall, and a connector formed on an upper edge of the wall and connected to the connective portion of the valve so that the switch is movable with the valve. The fin is movable in the window.

AI summary
A sprinkler includes a handle, a nozzle, a tube, a valve and a switch. The nozzle is connected to the handle. The tube is made in the handle and includes a window, a main channel in communication with a channel made in the nozzle, and an extensive channel in communication with the main channel via an intersection. The valve includes a gate, a positioning portion formed on the gate, and a connective portion formed on the positioning portion. The valve is rotationally inserted in the main channel so that the connective portion extends out of the tube. The switch includes an arched wall, a fin formed on an arched face of the wall, and a connector formed on an upper edge of the wall and connected to the connective portion of the valve so that the switch is movable with the valve. The fin is movable in the window.
