Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotating element is added to create pulsating spray, then cleaning performance is improved, but device complexity increases
Solution Approach 1:
The rotating element is driven by the water flow itself through deflecting surfaces, eliminating the need for external motors or power sources. The water jet automatically activates and drives the rotation mechanism, making the system self-powered and avoiding additional complex components.
Solution Approach 2:
The patent uses hydraulic principles by employing water flow as the driving force for the rotating element. The deflecting surfaces redirect the water jet to generate rotational motion, utilizing fluid dynamics to achieve the pulsating spray effect without mechanical motors.
2Productivity
If outlet openings are intermittently covered to create pulsation, then cleaning performance is improved, but water flow continuity may be affected
Solution Approach 1:
The rotating element periodically covers and uncovers the outlet openings, creating a pulsating spray pattern. This periodic action alternates between blocking and allowing water flow, generating the desired pulsating effect that enhances cleaning performance through varying water momentum.
Solution Approach 2:
The system maintains continuous water flow through the shower head by ensuring that while individual outlet openings are intermittently covered, the overall water supply remains uninterrupted. The rotating element's continuous motion ensures that water continuously exits through available openings, preventing pressure fluctuations and maintaining flow continuity.
3Adaptability or versatility
If multiple spray patterns are provided, then user versatility is improved, but device complexity increases
Solution Approach 1:
The rotating element serves multiple functions: it drives the pulsating spray mechanism, provides the pulsating motion itself, and can be adjusted to create different spray patterns. This single component performs what would traditionally require multiple separate mechanisms, reducing overall device complexity while maintaining versatility.
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 pulsating spray enhances cleaning performance by regularly changing water momentum, ensures continuous water flow without pressure fluctuations, and allows for efficient water use with multiple flow options.
Implementation Method 1
at least one rotating element is arranged in the annular channel such that it rotates along the annular channel when water emerges from the outlet
Implementation Method 2
at least one deflecting surface is arranged on the at least one rotating element, which causes a deflection of water in the annular channel in a circumferential direction along the annular channel in order to generate an impulse which supports a circular motion of the at least one rotating element

AI summary
Shower head (1) for a kitchen water tap having an outlet (2) for water, which is formed by a plurality of outlet openings (3), wherein the outlet openings (3) branch off from an annular channel (4), wherein at least one rotating element (5) is arranged in the annular channel (4) such that it rotates along the annular channel (4) when water exits the outlet (2), wherein the rotating element (5), as it rotates in the annular channel (4), briefly covers each individual outlet opening (3) so that an inflow of water to the respective outlet opening (3) is interrupted, thus causing a pulsation of water exiting the outlet openings (3) of the outlet (2).
