Hand-Held Sanitary Device Using Flexible Bag to Reduce Splashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for washing intimate body parts, such as water ejectors and hand-held shower heads, often result in splashing, making it difficult to wash areas like the perianal region without wetting other parts of the body.
Innovation Solution
A hand-held sanitary device that uses a sanitary bag filled with water for gentle surface washing of intimate body parts, combined with a mechanism for hot air drying, allowing for precise washing without splashing and eliminating the need for toilet paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If water ejectors or hand-held shower heads are used to wash intimate body parts, then washing coverage is improved, but splashing occurs and other parts of the body get wet
Solution Approach 1:
The patent introduces a flexible bag as an intermediary between the water source and the body part to be washed. The bag contains the water and directs it through a controlled outlet, preventing splashing while maintaining washing coverage. The bag acts as a mediator that transfers water from the rigid shower head to the flexible contact surface that touches the body.
Solution Approach 2:
The patent uses a flexible bag made of thin film material that can conform to the contours of intimate body parts. This flexible shell allows precise application of water to the target area while the material's flexibility prevents water from scattering or splashing onto surrounding areas.
2Reliability
If a jet of water is used to reach intimate body parts, then washing effectiveness is improved, but precision and control are reduced
Solution Approach 1:
The patent transforms the static water jet into a dynamic system where the flexible bag can be manually positioned, squeezed, and directed. The user can dynamically adjust the bag's position, the pressure applied, and the direction of water flow, providing both effectiveness and precision control.
Solution Approach 2:
The system allows the user to manually control the water flow by squeezing the flexible bag, providing self-service capability. The user can regulate the water pressure and direction according to their specific needs, improving both precision and ease of operation.
3Reliability
If traditional washing methods are used, then washing capability is achieved, but drying time is extended and hygiene is compromised
Solution Approach 1:
The patent combines the washing and drying functions into a single integrated system. The flexible bag system that provides controlled washing is paired with a hot air drying device, allowing the user to transition from washing to drying without leaving the device, thereby reducing drying time and improving hygiene.
Solution Approach 2:
The system enables continuous useful action by seamlessly transitioning from the washing phase to the drying phase. The hot air drying function activates immediately after washing, maintaining the useful action without interruption and significantly reducing the time the intimate areas remain wet.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enables effective and hygienic washing of intimate body parts with minimal water usage and quick drying, reducing the risk of splashing and promoting environmental sustainability by reducing toilet paper consumption.
Implementation Method 1
a conical stop with a ring that is subjected to the action of a compression spring for a tight holding of a single-use sanitary bag
Implementation Method 2
a resistor mounted around a water pipe, which constitutes the main part of the instantaneous water heater
Implementation Method 3
a second resistor with a small fan, which constitutes the main part of the dryer
Implementation Method 4
a pressure reducer which allows to limit the water pressure in the water supply hose and in the sanitary bag

AI summary
Disclosed is a hand-held sanitary device and to an impermeable and essentially biodegradable personal-hygiene sachet which can be filled with water and used for washing intimate body parts by gentle rubbing. The sanitary device chiefly includes a stop piece, a ring, a spring for keeping the personal-hygiene sachet sealed, a valve and connection to a water heater and dryer which is controlled by the valve. It can be used with running-water toilet bowls, without the need to use toilet paper. The sanitary device is particularly intended for the surface washing of intimate body parts, for vaginal washing, re-establishing pelvic-floor muscle tone, and pleasurable vaginal stimulation in women, using the hygienic sachet intended for each use.
