Movable Toilet Seat Basin for Gentle Perineal Cleansing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with limited mobility face challenges in effectively cleaning their perineal area due to the limitations of existing cleaning devices, which often require major plumbing alterations, additional floor space, or are not designed for personal use, and may cause overspray or discomfort.
Innovation Solution
A personal perineal cleansing system that can be installed in a shower, bathtub, or toilet without major plumbing changes, featuring a handheld device with a handle, accumulation basin, and sprayer, allowing for efficient cleaning and waste disposal, and optionally integrated into a toilet seat with a movable basin for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handheld shower wands are used to wash the perineal area, then cleaning can be performed, but the spray is too strong for delicate skin, the wand is too short, hard to manipulate, and angled incorrectly
Solution Approach 1:
The spray nozzle is designed with multiple spray holes of different sizes and angles to provide localized spray patterns suitable for different areas of the perineal region, delivering gentler spray for delicate skin areas while maintaining effectiveness for other regions
Solution Approach 2:
The spray wand incorporates an adjustable angle mechanism and flexible positioning capabilities, allowing the user to dynamically adjust the spray direction and angle to match the contours of the perineal area, improving both comfort and cleaning effectiveness
2Ease of operation
If conventional perineal cleansing systems are designed for hospital use by a caregiver, then cleaning can be performed, but the systems are too complex and expensive for personal use
Solution Approach 1:
The device is designed for independent personal use without requiring caregiver assistance. The spray wand is equipped with easy-to-operate controls and intuitive positioning mechanisms that enable users to perform perineal cleaning autonomously, eliminating the need for complex hospital-grade systems
Solution Approach 2:
The invention extracts only the essential cleaning function from complex hospital systems, creating a simplified standalone device that focuses solely on perineal irrigation without unnecessary additional features, controls, or subsystems
3Ease of operation
If bidets are installed as standalone bowl structures, then perineal cleansing can be provided, but additional floor space is required and major plumbing alterations are needed
Solution Approach 1:
The device merges the perineal cleansing function with existing bathroom fixtures such as the shower area or toilet, eliminating the need for separate bidet installations and additional floor space. The spray wand can be used in conjunction with the existing shower stream or connected to toilet water supply
4Ease of manufacture
If attachable bidet sprayers are used, then installation is simpler, but they do not adequately cleanse and cause overspray
Solution Approach 1:
The spray nozzle features multiple precisely angled spray holes that direct water flow locally and accurately onto the perineal area, preventing overspray while maintaining adequate cleansing coverage. Different spray holes are oriented to target specific anatomical regions for effective cleaning
Solution Approach 2:
The spray system incorporates adjustable flow rate and spray pattern parameters, allowing optimization of water delivery to achieve effective cleansing without excessive spray dispersion. The nozzle design modifies spray characteristics to concentrate flow where needed while minimizing overspray

AI summary
A personal perineal cleansing system includes a specialized toilet seat comprising a basin with an interior sprayer, a horizontal portion upon which the user sits, a vertical portion disposed behind the user when seated, and a basin re-positioning system that moves the basin from the functional position (near the center of the toilet bowl) within the horizontal portion to the storage position in the vertical portion. The basin re-positioning system may be manually or electronically activated.
