Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent fountains are used to create varied water patterns, then water pattern variability is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements nested water channels where an inner water channel is surrounded by an outer water channel. The inner channel produces a central water jet while the outer channel produces a surrounding water ring. This nested configuration allows multiple water patterns to be generated within a single integrated nozzle structure, eliminating the need for multiple separate fountain units while maintaining pattern variability.
Solution Approach 2:
The nozzle is segmented into distinct functional zones with separate water channels for different flow patterns. The inner channel handles central jet formation while the outer channel handles peripheral water ring formation. This segmentation allows independent control of each channel's water flow, enabling diverse pattern combinations without requiring multiple complete fountain systems.
2Manufacturing precision
If separate pumps control each water channel for pattern variation, then water pattern control precision is improved, but device complexity increases
Solution Approach 1:
The patent incorporates movable flow guides within both the inner and outer water channels. These flow guides can be adjusted to dynamically change the water flow distribution and pattern characteristics. This dynamic adjustment mechanism provides precise control over water patterns without requiring multiple complex pump systems, as the flow guides can redirect and modulate the water flow from single or multiple pumps.
Solution Approach 2:
The patent uses adjustable flow guides that can change the flow parameters (direction, distribution, velocity) of water through the channels. By modifying the position and orientation of these flow guides, the system achieves precise control over water pattern characteristics such as jet width, height, and shape, providing fine-tuned control without increasing pump system complexity.
3Ease of manufacture
If concentric tubes are used to form water channels, then manufacturing simplicity is improved, but flow control flexibility may be limited
Solution Approach 1:
While maintaining the simple concentric tube structure for ease of manufacture, the patent incorporates movable flow guides within the channels. These flow guides can be adjusted to change the flow patterns dynamically, adding flexibility to the otherwise simple concentric structure. The flow guides can be positioned at different angles and locations to create various water patterns including jets, rings, and hybrid patterns.
Solution Approach 2:
The concentric tube structure is segmented into distinct flow paths with separate control mechanisms. The inner tube forms one water channel while the outer tube forms another, with flow guides positioned in each channel to independently control the water flow. This segmentation of the concentric structure maintains manufacturing simplicity while enabling flexible flow control through the adjustable flow guides.
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 achieves a simple yet highly variable water pattern generation, enabling efficient control of jet shapes from slim fountains to wide cups through electronic pump control and movable flow guides, enhancing stability and precision.
Implementation Method 1
Two or more pumps can be or will be connected to the water feed separately to be controlled. The water patterns can already be varied by the ratio of the respective volume flows

AI summary
Disclosed is a water feature nozzle comprising at least two separate water guides (1, 3) each with at least one outlet opening (13, 14), wherein controllably different water volume streams (V1,V2) can be directed to the outlet openings (13, 14) via the water guides (1, 3) in order to generate variable water patterns at a nozzle outlet (9), the water feature nozzle being designed such that an inner water guide (1) is surrounded by at least one outer water guide (3), and both water guides (1, 3) direct parallel-orientated water streams (V1,V2) as far as the nozzle outlet (9). One of the water guides (1, 3) has an adjustable flow deflector (10, 11) on the nozzle outlet (9), which flow deflector (10, 11) annularly encloses the inner water jet.
