Urinal Condom Application With Detachable Vacuum Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinal condom application systems face issues with inconsistent vacuum connections leading to incomplete suction or permanent adhesion, making them difficult to use and prone to leaks or folds, especially for individuals with limited dexterity or anatomical challenges.
Innovation Solution
A system with a vacuum pump and connection unit featuring congruent surfaces with uneven structures and seals, ensuring a flow-tight connection while allowing easy detachment, and a receiving bell with a groove for the condom ring to facilitate optimal positioning and wrinkle-free application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection between vacuum pump and connection unit is made tight to ensure sufficient vacuum, then the vacuum strength is improved, but the detachability of the units is worsened as they become stuck together
Solution Approach 1:
The connection system is divided into separate components: a connection unit with external threading and a vacuum pump with internal threading. This segmentation allows the components to be easily assembled and disassembled while maintaining a tight seal when connected, resolving the contradiction between secure connection and ease of detachment.
Solution Approach 2:
A sealing element (O-ring or similar) acts as an intermediary between the connection unit and vacuum pump. This intermediary provides the necessary sealing to maintain vacuum while allowing for easy detachment when the sealing element is compressed during connection and relaxed during detachment, solving the contradiction between connection reliability and detachability.
2Ease of operation
If the connection is made loose to allow easy detachment, then the detachability is improved, but the vacuum consistency is worsened leading to incomplete suction or leaks
Solution Approach 1:
The threaded connection design segments the sealing function from the mechanical connection. The external threading on the connection unit combines with internal threading in the vacuum pump to create a secure mechanical bond that also provides a tight seal, ensuring both easy detachment and vacuum consistency.
Solution Approach 2:
The sealing element serves as an intermediary that maintains vacuum consistency while allowing easy detachment. When the connection is made, the sealing element is compressed to create a tight seal; when detachment is required, the sealing element relaxes, allowing the units to be separated without damage, thus resolving the contradiction between vacuum consistency and detachability.
3Manufacturing precision
If the receiving bell is designed with a groove for the condom ring to ensure optimal positioning, then the application precision is improved, but the device complexity is worsened
Solution Approach 1:
Instead of making the entire receiving bell complex, a simple groove is added locally at the critical position where the condom ring needs to be positioned. This localized feature provides the necessary guidance and positioning precision without adding complexity to the rest of the device structure.
Solution Approach 2:
The receiving bell is designed as a simple cylindrical structure with a separate groove feature. This segmentation allows the groove to be added as a minor modification to an otherwise simple structure, achieving precise positioning without significantly increasing overall device complexity.
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
Ensures a secure, wrinkle-free application of urinal condoms by maintaining a consistent vacuum and easy detachment, simplifying the process for users with varying sizes and dexterity levels, reducing leaks and improving fit.
Implementation Method 1
the penis is sucked into the area of the urinal condom in contact with the receiving bell due to the negative pressure generated by the operation of the vacuum pump
Implementation Method 2
At least one of the two surfaces is provided with an uneven structure to prevent the two surfaces lying on top of each other from sticking to each other

AI summary
A system for applying a urinal condom which enables the application of a urinal condom for patients. The system ensures a good fit of the urinal condom and simplifies application. The system includes a receiving bell, a vacuum pump and a connecting unit for fluidically connecting the receiving bell to the vacuum pump. The connecting unit has a tubular channel, to which the receiving bell is fluidically connected. The tubular channel being designed on the receiving bell side as a receptacle for a hose attachment of the urinal condom. The connecting unit has a surface on the side to be connected to the vacuum pump, which is congruent with a surface formed on the vacuum pump. At least one of the two surfaces have an uneven structure, and the vacuum pump and the connecting unit are fluidically connected via the two superimposed surfaces.
