Vaginal Collection Device with Ventilation Shaft for Pressure Equalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices do not effectively absorb and control the discharge of liquid excretions from the vagina, particularly semen, leading to uncontrolled leakage and discomfort after sexual activity, which current hygiene products fail to prevent.
Innovation Solution
A device with a hollow collection container having multiple holes for absorption, a shaft for air supply to prevent pressure differences, and a handle for insertion and rotation, allowing controlled discharge and potential reuse by disassembling for cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a collection container with holes is inserted into the vagina to absorb liquid excretions, then the absorption capability is improved, but uncontrolled leakage occurs due to pressure differences during insertion and removal
Solution Approach 1:
The device segments the collection container into multiple functional zones: an upper closed end for controlled discharge, a lower open end for absorption, and intermediate holes for selective liquid intake. This segmentation allows different parts of the device to perform different functions simultaneously, enabling both absorption and controlled discharge.
Solution Approach 2:
The device utilizes dynamic pressure changes during insertion and removal to control liquid flow. During insertion, positive pressure pushes liquid into the container through holes; during removal, negative pressure prevents leakage. The flexible container walls dynamically adjust to pressure changes, enabling controlled discharge without active mechanisms.
2Manufacturing precision
If the collection container is made with small holes for selective liquid intake, then the precision of liquid absorption is improved, but the manufacturing complexity increases
Solution Approach 1:
The collection container incorporates holes with specific diameter ranges (0.8-1.5mm) that function as a porous structure. These holes provide selective permeability based on capillary pressure, allowing precise control of liquid intake without requiring complex active filtering mechanisms. The porous-like structure achieves precision through passive physical principles.
Solution Approach 2:
The device controls liquid absorption by changing pressure parameters during insertion and removal. The hole diameter (0.8-1.5mm) is optimized to work with natural pressure changes in the vaginal environment, allowing precise liquid intake control through simple dimensional parameters rather than complex manufacturing processes.
3Loss of substance
If the collection container is designed to be removed and cleaned for reuse, then the loss of substance is reduced, but the device complexity increases due to disassembly requirements
Solution Approach 1:
The collection container is segmented into detachable components (container body, shaft, handle) that can be easily separated for cleaning and reassembly. This segmentation enables the container to be emptied and cleaned without discarding the entire device, reducing material loss while keeping the disassembly mechanism simple through basic connection interfaces.
Solution Approach 2:
The device design allows the collection container to be recovered and cleaned for reuse instead of being discarded after single use. The simple detachable structure enables easy emptying and cleaning of the container body, making the device economically and environmentally sustainable by extending its service life through multiple uses.
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
Prevents uncontrolled ejaculation and soiling, ensuring comfortable and hygienic handling by effectively absorbing and discharging semen through the device's designed structure, which can be cleaned and reused.
Implementation Method 1
a collection container (12) for absorbing and collecting liquid excretions
Implementation Method 2
A shaft (14), which is permanently connected to the collection container (12), thereby protruding with a first (top) end partially through one of the ends of the collection container (12) along the longitudinal axis of the collection container into the collection container

AI summary
The device (10) has a handle (16) fixed to an end of a shaft (14). The handle is provided for the insertion of a detachable collection container (12) into a vagina, for rotation of the collection container about its longitudinal axis within the vagina or for the removal of the collection container from the vagina. The handle is provided with a hole (24), which is connected with the hollow interior of the shaft or a ventilation tube to ensure the supply of air to prevent pressure differences during removal of the collection container from the vagina. An independent claim is included for a method for absorption and controlled discharge of liquid excretion from a vagina.
