Movable Nozzle Sitz Bath for Intimate Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washbasins require high coordination and skill to adjust the liquid jet for intimate hygiene, making the process difficult and inefficient.
Innovation Solution
A washbasin with a movable nozzle for dispensing liquid, integrated with a thermostatic mixer and manually or electrically operable valves, allowing for controlled and directed liquid delivery without user movement, and a method to convert conventional washbasins to include these features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pivoting fluid outlet is used in the washbasin, then the liquid jet can be directed to different body parts, but the user must have high coordination and dexterity to correctly adjust the fluid jet during intimate hygiene
Solution Approach 1:
The nozzle moves automatically through the liquid stream to position itself for optimal cleaning, eliminating the need for manual adjustment by the user. The liquid flow itself drives the nozzle movement and positioning, making the system self-regulating and easy to operate.
Solution Approach 2:
The manual mechanical adjustment system is replaced with an automated liquid-driven movement system. Instead of requiring user hand movements to pivot the outlet, the liquid stream itself propels and positions the nozzle automatically.
2Device complexity
If the nozzle is fixed in position, then the device structure is simple, but the user must move their body to different positions on the basin to access different cleaning areas
Solution Approach 1:
The nozzle transitions from a fixed position to a dynamically movable position, driven by the liquid stream. This allows the cleaning device to adapt its position automatically, eliminating the need for user body movement while maintaining structural simplicity.
Solution Approach 2:
The liquid stream itself is used as the driving force to move the nozzle, utilizing hydraulic principles. The flowing liquid provides both the cleaning function and the actuation mechanism for nozzle movement.
3Ease of operation
If a movable nozzle is added to the washbasin, then intimate cleansing is facilitated without user coordination, but the device complexity increases
Solution Approach 1:
The nozzle movement is self-driven by the liquid flow, requiring no additional motors, actuators, or control systems. The liquid stream simultaneously performs cleaning and actuation functions, minimizing added complexity.
Solution Approach 2:
The hydraulic system uses the existing water supply infrastructure and liquid stream to drive nozzle movement, avoiding the need for separate power sources or complex mechanical actuation systems.

Function Achieved in This Case
Facilitates easier and more effective intimate hygiene by eliminating the need for user coordination in directing the liquid jet, enhancing cleaning efficiency and comfort.
Implementation Method 1
The at least one nozzle can be moved, in particular automatically, by the liquid, by a liquid pressure of the liquid, and/or in a linear direction
