Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beauty shower systems face issues with inaccurate mixing concentration and poor use effect of beauty liquids due to dilution in storage, leading to bacterial growth and ineffective skin care.
Innovation Solution
A water outlet mechanism with a flow rate adjustment mechanism that adjusts the suction frequency of a water operated pump to control the mixed ratio of functional liquids and water, using a tapered adjustment core and operating member to alter water flow through multiple passage holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If water flow rate into the beauty liquid storage cavity is increased to adjust mixing concentration, then the mixing concentration can be adjusted, but the beauty liquid is diluted in advance and the effect becomes poor
Solution Approach 1:
The patent extracts the mixing process from the storage cavity by introducing a separate mixing chamber. Water and beauty liquid are mixed in the mixing chamber after the beauty liquid has been stored, rather than mixing them in the storage cavity. This separation allows concentration adjustment without premature dilution in the storage space.
Solution Approach 2:
The patent introduces a mixing chamber as an intermediary component between the storage cavity and the outlet. This intermediate chamber provides a dedicated space for mixing water and beauty liquid, preventing direct dilution in the storage cavity while enabling precise concentration control through controlled water injection into the mixing chamber.
2Duration of action of stationary object
If water enters the beauty liquid storage cavity for a long time, then the storage cavity can be refilled, but bacteria easily breed in the water
Solution Approach 1:
The patent segments the system into a storage cavity for holding beauty liquid and a separate mixing chamber for water mixing. This segmentation prevents water from remaining in the storage cavity, eliminating the breeding environment for bacteria while maintaining long-term storage capability for the beauty liquid itself.
Solution Approach 2:
The patent extracts water from the storage cavity environment by providing a separate mixing chamber. Water is injected only into the mixing chamber for immediate mixing and discharge, rather than being stored in the beauty liquid storage cavity. This extraction of water from the storage environment eliminates the condition for bacterial breeding.
3Measurement precision
If a flow rate adjustment mechanism is added to control suction frequency, then mixed ratio control is improved, but device complexity increases
Solution Approach 1:
The patent employs a flow rate adjustment mechanism that utilizes the water flow itself to drive the adjustment. The water pressure and flow rate automatically influence the mixing process, reducing the need for complex external control systems while maintaining precise mixed ratio control through the inherent properties of the water flow.

AI summary
A water outlet mechanism for adjusting a mixed ratio of a functional liquid comprises a water operated pump driven by water power, a functional liquid storage chamber, a water outlet channel, a water inlet channel, and a flow rate adjustment mechanism. A liquid inlet of the water operated pump is in communication with the functional liquid storage chamber, a liquid outlet of the water operated pump is in communication with the water outlet channel or the water inlet channel, and the flow rate adjustment mechanism is configured to adjust a water flow rate of the water in the water inlet channel for driving the water operated pump so as to change a suction frequency of the water operated pump.
