Bidet Nozzle Assembly With Motor-Driven Vertical Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bidet nozzle designs, where nozzles are arranged side by side either horizontally or vertically, face challenges in accurately targeting genital and anal areas due to misalignment and require high water pressure for proper operation, leading to inefficient washing and user discomfort.
Innovation Solution
A nozzle assembly with bidet and washing nozzles arranged vertically, utilizing a gear train and rack wire system driven by a motor to precisely align and operate the nozzles, ensuring accurate water spray regardless of water pressure levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If nozzles are arranged side by side on identical horizontal plane, then washing and bidet functions can be provided, but nozzles cannot be located right under genital and anal areas causing misalignment and spraying to undesired regions
Solution Approach 1:
The patent changes the nozzle arrangement from horizontal side-by-side to vertical stacking arrangement. The bidet nozzle is positioned above the washing nozzle in the vertical direction, allowing both nozzles to be located directly under their respective target areas (genital and anal areas) without horizontal deviation, thereby improving alignment precision
2Volume of stationary object
If nozzles are arranged side by side in vertical direction, then volume occupied by nozzles is reduced, but nozzles require high water pressure to advance accurately which is not available at locations with low water pressure
Solution Approach 1:
The patent replaces the water-pressure-driven mechanical advancement system with an electric motor-driven system. A motor rotates a gear train that converts rotational motion to linear motion through rack and pinion mechanisms, advancing the nozzles independently of water pressure conditions, thereby ensuring reliable operation in locations with low water pressure
Solution Approach 2:
The patent introduces a gear train as an intermediary mechanism between the motor and the nozzles. The gear train includes driving gears, driven gears, and rack wires that transmit and convert the motor's rotational force into precise linear advancement of the nozzles, enabling controlled movement regardless of water pressure
3Ease of operation
If water pressure is used to advance nozzles, then simple operation is achieved, but accurate location cannot be reached when water pressure is lower than predetermined level
Solution Approach 1:
The patent replaces the direct water-pressure-driven nozzle advancement with an electric motor and gear train system. The motor provides controlled rotational force that is transmitted through gears and rack wires to advance the nozzles to precise positions, ensuring accurate positioning independent of water pressure variations

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces bidet volume, improves alignment with genital and anal areas for accurate water spray, and enhances operational reliability by ensuring consistent nozzle operation across varying water pressures.
Implementation Method 1
a gear train comprising a driving gear connected to the driving motor to transmit rotational force of the driving motor, a first nozzle gear reciprocating the washing nozzle by receiving the rotational force from the driving gear, and a second nozzle gear reciprocating the bidet nozzle by receiving the rotational force from the driving gear
Data Source
AI summary
A nozzle assembly for a bidet includes a washing nozzle, a bidet nozzle mounted under the washing nozzle, a driving motor driving the washing nozzle and/or the bidet nozzle, a gear train, and a nozzle case for receiving the washing and bidet nozzles and the gear train. The gear train includes a driving gear connected to the driving motor to transmit rotational force of the driving motor, a first nozzle gear reciprocating the washing nozzle by receiving the rotational force from the driving gear, and a second nozzle gear reciprocating the bidet nozzle by receiving the rotational force from the driving gear.
