Nozzle Cover Element for Internal Water Jet Illumination
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.
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
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.
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 solution enhances the aesthetic appeal and durability of the device by ensuring internal illumination of the water jet, allowing for varied spray patterns and flow rates, reducing maintenance needs and visual distraction.

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).
