Solution Overview

Problem

Existing water sprayers for pools face issues with LED illumination functionality being dependent on water pressure and flow rate, leading to potential LED burnout or inadequate lighting, and suffer from uneven water flow due to traditional piping structures and viscosity properties, resulting in irregular water sheet outputs.

Innovation Solution

A water sprayer design featuring a power generating mechanism along the water passageway that uses flowing water to power an LED light source independently of water pressure and flow rate, combined with an elongate outlet nozzle with a specific shape calculated using the formula Y = a4*x^4 + a2*x^2 + a0 to ensure consistent water flow and even water sheet distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If water flow generator mechanisms are used to power LED illumination, then the LED can be powered without batteries, but the voltage and current supplied are dependent on water pressure and water flow rate, causing LED burnout when pressure/flow are high or insufficient lighting when pressure/flow are low

Engineering Contradiction:
ImproveLED illumination powerVSAvoidLED operational stability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent applies parameter changes by using a voltage stabilizing circuit and current limiting circuit to regulate the electrical parameters (voltage and current) supplied to the LED. These circuits transform the variable voltage/current from the water flow generator into stable, controlled parameters that match the LED's rated specifications, resolving the contradiction between battery-free operation and operational stability.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If traditional piping structures are used in water sheet sprayers, then the structure is simple, but water viscosity properties cause uneven and irregular water flow at the output, resulting in poor appearance and comfort of the water sheet

Engineering Contradiction:
Improvepiping structureVSAvoidwater flow uniformity
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies segmentation by dividing the water passageway into multiple sections with different cross-sectional areas. The outlet nozzle is segmented into an elongated section and a widened section, creating staged expansion that gradually adjusts water flow distribution. This segmented structure prevents sudden flow changes and ensures uniform water sheet output while maintaining reasonable structural complexity.

Inventive Principle:
Principle #1Segmentation

3Shape

If the outlet structure size is significantly larger than the inlet structure size, then a water sheet output can be formed, but traditional piping structures and water viscosity cause uneven water flow, heightening the disadvantages of irregular output

Engineering Contradiction:
Improvewater sheet outputVSAvoidwater flow consistency
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by incorporating a rectifying chamber before the outlet nozzle that pre-adjusts the water flow. The rectifying chamber with its baffle plates and streamlined design prepares the water flow in advance, reducing turbulence and viscosity effects before water enters the elongated outlet section. This preliminary flow conditioning ensures consistent water sheet formation even with significant size difference between inlet and outlet.

Principle #10Preliminary action
