Solution Overview

Problem

Existing illuminated water jet devices inadequately illuminate the water jet from the outside, are visually distracting, and have exposed light sources prone to mechanical damage, limiting their application and maintenance needs.

Innovation Solution

A device with a separate cover element protecting the light sources and allowing variable water flow and jet shape, where LEDs are positioned below or within the cover element to internally illuminate the water jet, providing mechanical protection and adjustable flow rate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If light sources are arranged on the base body to illuminate the water jet from the side, then the water jet is illuminated, but the light sources are visually strong and annoying, and the illumination is insufficient

Engineering Contradiction:
Improvewater jet illuminationVSAvoidvisual distraction
Core Design Contradiction:
Illumination intensityVSObject-generated harmful factors

Solution Approach 1:

Instead of illuminating the water jet from the outside (side illumination), the patent inverts the approach by placing light sources inside the cover element to illuminate the water jet from the inside. This internal illumination achieves better lighting效果 while hiding the light sources, eliminating visual distraction.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The cover element serves as an intermediary structure that houses the light sources and directs their light through the water jet. This mediator allows the light to be delivered effectively while concealing the light sources from view, resolving the contradiction between illumination and visual distraction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Illumination intensity

If light sources are arranged on the base body, then the water jet can be illuminated, but the light sources are easily exposed to mechanical damage

Engineering Contradiction:
Improvewater jet illuminationVSAvoidlight source protection
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The light sources are nested inside the cover element, which acts as a protective housing. This nested structure shields the light sources from mechanical damage while still allowing them to illuminate the water jet effectively, thus improving reliability without sacrificing illumination.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If a fixed water outlet opening is provided, then the device structure is simple, but the spray pattern and flow rate cannot be varied

Engineering Contradiction:
Improvedevice structureVSAvoidspray pattern variation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The cover element is designed with variable connection to the base body, allowing it to be adjusted to different positions. This dynamic adjustment capability enables variation of the water outlet opening and spray pattern while maintaining a relatively simple overall structure, thus improving adaptability without excessive complexity.

Inventive Principle:
Principle #15Dynamics

4Stability of the object's composition

If the cover element is fixed to the base body, then the structure is stable, but the water flow and jet shape cannot be adjusted

Engineering Contradiction:
Improvedevice stabilityVSAvoidflow rate adjustment
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connection between the cover element and base body is designed to be variable rather than fixed. This allows the cover element to be adjusted to different positions, enabling control over water flow and jet shape while maintaining structural stability during operation. The dynamic connection resolves the contradiction between stability and adjustability.

Inventive Principle:
Principle #15Dynamics

AI summary

Lights (6) are fastened in the main body (4, 5) of the nozzle, near a water outlet opening (12). In novel design, the water outlet opening is formed in a separate covering component (11) which overlaps the illumination unit (6). The water outlet opening is located centrally above the illumination unit (6). The lights are fixed centrally on a carrier (4). A connector (5) for a water hose is attached to the main body. This is optionally also attached to an object acting as a source of water (e.g. a rock).
