Solution Overview

Problem

Conventional guiding pipes for water sprayers are simple round tubes, which hinder the acceleration of water flow before it is sprayed, resulting in inefficient water supply for garden watering or washing purposes.

Innovation Solution

A guiding pipe with a spiral main tube and circular connecting sections at each end, providing a tight seal and allowing water to rotate rapidly within the pipe, enhancing flow and spray power without additional pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple round tube is used as the guiding pipe, then the device complexity is reduced, but the water flow speed and spray power are insufficient

Engineering Contradiction:

Improveguiding pipe structureVSAvoidwater flow speed

Core Design Contradiction:

Device complexityVSSpeed

Solution Approach 1:

The guiding pipe employs a spiral curved structure instead of a straight round tube. This curvature design causes water to rotate rapidly as it flows through the pipe, increasing water flow speed and spray power while maintaining structural simplicity

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The spiral structure utilizes hydraulic principles to convert the kinetic energy of flowing water into rotational motion. The curved path creates centrifugal forces that accelerate water flow and enhance spray performance without requiring additional pressure

Inventive Principle:

Solution Approach 1:

The spiral curved structure is formed by bending the tube in a helical pattern. This geometric transformation alone generates the rotational water flow and enhanced spray power without requiring complex mechanical components, pumps, or valves

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The invention changes the geometric parameter of the tube from straight to spiral, with specific pitch and diameter ratios. This parameter modification fundamentally alters water flow characteristics, increasing spray power while keeping the structure simple and manufacturable
