Solution Overview
Problem
Existing shower heads fail to provide a comfortable water flow experience and are not water-efficient, with water spraying about and poor water-saving effects, especially in low-pressure environments.
Innovation Solution
A shower head structure featuring a main body, face plate with multiple jet orifices arranged in a specific pattern, a bubbler, and a switching device that controls water flow, creating a bunched spout of water for increased force and reduced spray, suitable for low-pressure environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If water flows through large openings in existing shower heads, then water flow volume is high, but water sprays about and water-saving effect is poor
Solution Approach 1:
The shower head divides water flow into multiple separate streams through multiple jet orifices arranged in specific patterns. Each jet orifice creates a focused water stream, and the collective arrangement of multiple jets produces a bunched spout effect that prevents water from spraying about while maintaining high water flow volume.
Solution Approach 2:
Different regions of the shower head face plate have different orifice configurations. The jet orifices are arranged in specific patterns (circular, oval, pentagonal, triangular, or crescent shapes) with controlled spacing (distance more than 1 mm) and specific diameters (0.5 mm-0.7 mm), creating localized focused water streams that collectively form a cohesive bunched spout.
2Use of energy by moving object
If water pressure is low, then energy consumption is reduced, but water flow force is insufficient and water-saving effect deteriorates
Solution Approach 1:
The shower head optimizes the geometric parameters of the jet orifices (diameter of 0.5 mm-0.7 mm and spacing of more than 1 mm) to maximize water flow force under low pressure conditions. The specific orifice dimensions and arrangements are designed to create high-velocity focused streams that maintain strong water flow force even when supply pressure is low, achieving both energy efficiency and effective water delivery.
3Force
If jet orifice diameter is small, then water flow force is stronger and water-saving effect is improved, but water flow volume may be reduced
Solution Approach 1:
The shower head uses multiple jet orifices with small diameters (0.5 mm-0.7 mm) arranged in specific patterns. While each individual jet produces a focused high-force stream, the collective output of multiple jets maintains adequate total water flow volume. The segmentation allows each jet to optimize for force while the group maintains volume.
Solution Approach 2:
Multiple individual jet streams are arranged to form a bunched spout configuration where the streams are close together but distinct. This merging of multiple focused streams creates a cohesive water flow pattern that combines the high force of individual jets with the cumulative volume of multiple jets, preventing water dispersion while maintaining both force and volume.

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 shower head structure provides a soft and comfortable bubble water experience while enhancing water-saving efficiency by directing water into a focused, stronger fine spout, effectively managing water flow in low-pressure conditions.
Implementation Method 1
the water outlet unit includes at least two jet orifices... The water flowing from the plurality of jet orifices forms a bunched spout

AI summary
A shower head structure 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. The water flowing from the plurality of jet orifices forms a bunched spout. The bunched spout includes a plurality of fine spouts. The water won't spray about. Since the diameter of the jet orifice is small, the force of the fine spouts is stronger. The water-saving effect is good. The shower head can be used for low pressure environment.
