Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower heads often provide uneven water flow patterns that are wasteful and do not offer a comfortable showering experience, failing to conserve water effectively, especially in low-pressure environments.
Innovation Solution
A shower head assembly with a main body and face plate featuring clusters of jet orifices spaced at least 1 mm apart, with diameters ranging from 0.2 mm to 0.7 mm, arranged to create a 'bubble water flow' that reduces random spray and conserves water, including a bubbler and a switching device for controlling water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional shower heads use large orifices for water discharge, then water flow volume is increased, but water pressure and comfort are reduced while wasting water
Solution Approach 1:
The shower head divides water discharge into multiple clusters of jet orifices (e.g., 5-10 orifices per cluster, with 3-5 clusters total) instead of using a single large opening. Each jet orifice has a small diameter (0.2-0.7mm), creating focused water jets that maintain pressure while distributing water efficiently. This segmentation resolves the contradiction by providing both adequate water volume and comfortable high-pressure spray.
Solution Approach 2:
Different regions of the shower head face plate have different orifice configurations. The center region contains a bubbler with larger diameter (0.8-1.5mm) for gentle water flow, while the circumferential region contains jet orifices with smaller diameters (0.2-0.7mm) for high-pressure spray. This local differentiation allows the shower head to provide both gentle and forceful water flow in different areas, resolving the comfort-pressure contradiction.
2Area of stationary object
If conventional shower heads spray water in random pattern, then water coverage area is increased, but water-saving effect is reduced
Solution Approach 1:
The shower head uses segmented cluster arrangements where jet orifices are grouped in specific patterns (e.g., triangular, circular, or linear arrangements) rather than random distribution. The clusters are positioned at predetermined distances (e.g., 1-5mm spacing) to create focused water streams that cover the body efficiently without random spray waste. This organized segmentation maintains coverage area while reducing water waste through targeted delivery.
Solution Approach 2:
The switching device enables periodic alternation between different water discharge modes: a first mode where water flows from the center bubbler only, and a second mode where water flows from both the center bubbler and circumferential jet orifices. This periodic switching allows users to alternate between gentle full-coverage flow and concentrated high-pressure spray, optimizing water usage based on showering needs while maintaining effective coverage area.
3Force
If conventional shower heads are designed for high pressure, then water discharge force is increased, but adaptability to low pressure environments is reduced
Solution Approach 1:
The shower head uses small-diameter jet orifices (0.2-0.7mm) that create high-velocity water jets even at low supply pressures. The small orifice size increases water velocity according to Bernoulli's principle, maintaining discharge force in low-pressure environments. Additionally, the cluster arrangement and predetermined spacing optimize flow patterns to maximize force efficiency, enabling the shower head to adapt to various pressure conditions while maintaining comfortable spray force.
Solution Approach 2:
The shower head design with switchable modes provides universal adaptability to different water pressure environments and user preferences. The switching device enables alternation between a first discharge mode (center bubbler only for gentle flow) and a second discharge mode (both center and circumferential orifices for enhanced spray). This multi-functionality allows the same shower head to effectively operate in both low-pressure and higher-pressure environments, resolving the adaptability contradiction.
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 provides a soft and comfortable water flow while conserving water, maintaining efficiency even in low-pressure environments by creating clusters of thin water jets with strong force, reducing unsuitable splashing and enhancing water-saving effects.
Implementation Method 1
The discharged water flow is grouped or arranged to provide 'bubble water flow' that feels soft and comfortable to the user
Implementation Method 2
the jet orifices have a very small diameter, such as 0.2 mm-0.7 mm. Since the diameter of the jet orifice is small, the force of the fine spouts is strong

AI summary
A shower head assembly includes a main body, a face plate, and a switching device installed inside the main body for controlling an outflow of water from the face plate. The circumferential portion of the face plate is provided with a plurality of water outlet units. Each water outlet unit includes a plurality of jet orifices for producing a plurality of fine spouts. Since the diameter of each jet orifice is small, the water discharge force of the fine spouts is stronger. The water-saving effect is good. The shower head can be used for a low water pressure environment.
