Dynamic drying mechanism for a wash and clean system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bidet systems are not suitable for washing and drying female anterior private parts, are expensive, require pre-installation, and lack movable drying mechanisms and localized delivery of cleaning solutions or medications.
Innovation Solution
A bidet seat system with a toilet seat assembly, a drying nozzle assembly, and a spraying nozzle assembly that includes retractable and rotatable nozzle units controlled by user input, allowing for adjustable air delivery and solution application to specific body regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed water spray nozzle is positioned near posterior areas in bidet systems, then cleaning function is provided for anal areas, but the system cannot wash female anterior private parts or provide localized cleaning for different body regions
Solution Approach 1:
The patent implements a movable drying nozzle assembly that can be freely positioned and localized to different areas of the human body. The drying nozzle is connected to a moving mechanism that allows it to move to a desired position, enabling it to dry not only anal areas but also female anterior private parts and other body regions, thus resolving the limitation of fixed nozzle positioning while maintaining system simplicity
Solution Approach 2:
The bidet system is designed with both a water spray nozzle assembly and a drying nozzle assembly that can service multiple body regions. The drying nozzle assembly can be positioned to dry various areas including anal regions, female anterior private parts, and other body parts, making the system universal for different cleaning and drying needs without requiring multiple separate devices
2Ease of operation
If bidet systems are pre-installed in toilets, then washing function is provided, but the systems are expensive and not portable or convenient to carry
Solution Approach 1:
The patent divides the bidet system into separate functional modules: a water spray nozzle assembly, a drying nozzle assembly, and a base housing. These modular components can be manufactured independently and assembled together, reducing manufacturing complexity while enabling portability. The system can be installed on existing toilets or potentially detached for relocation, addressing both ease of operation and manufacturing considerations
3Adaptability or versatility
If drying mechanisms in bidet systems are fixed in position, then drying function is provided for specific areas, but the mechanisms cannot freely move or localize to areas that need drying
Solution Approach 1:
The drying nozzle assembly is equipped with a moving mechanism that enables it to freely move and position itself at desired locations on the human body. This dynamic positioning capability allows the drying function to be localized precisely where needed, providing adaptability for different body regions while the mechanism remains integrated within the existing bidet system structure
Solution Approach 2:
The patent introduces a control mechanism that acts as an intermediary between the user and the drying nozzle assembly. The control mechanism receives user input and directs the movement of the drying nozzle to the appropriate position, enabling localized drying without requiring complex automated control systems or multiple motors
4Ease of operation
If bidet systems use fixed nozzle positions, then simple structure is maintained, but the systems cannot provide hands-free operation or adjustable positioning for different users
Solution Approach 1:
The bidet system is designed to automatically respond to user needs without requiring manual adjustment of nozzle positions. The system includes sensors or control mechanisms that detect user presence and automatically position and activate the water spray and drying nozzles, providing hands-free operation while maintaining relatively simple control logic based on user input signals
