Negative Pressure Assistance Device for Male Sexual Dysfunction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for male sexual dysfunction fail to maintain a consistent erection state and cause discomfort, leading to integration issues with the penis and partner, and often require tightening mechanisms that are not natural.
Innovation Solution
A two-layer device with a hard sack simulating an erect penis covered in silicone rubber, featuring an air vent hole at the front end and a deviated air vent hole in the soft skin, allowing air discharge and preventing outside air entry, providing a valve function for negative pressure application without the need for belts or tightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a sack-like device is used to simulate an erect penis, then the appearance is improved, but the device easily falls out and causes discomfort
Solution Approach 1:
The patent applies negative pressure suction through a pump to create a vacuum state within the device chamber, which firmly holds the penis in place and prevents the device from falling off. The air vent hole with valve mechanism controls the negative pressure state, allowing the device to maintain stable attachment while preserving the simulated erect appearance.
2Shape
If tightening devices are used to achieve erection state, then the erection effect is improved, but the integration with the penis is poor and causes discomfort
Solution Approach 1:
Instead of mechanical tightening, the patent uses negative pressure suction to create a vacuum state that naturally draws and holds the penis in the desired erection position. This pneumatic approach eliminates the need for uncomfortable tightening mechanisms while maintaining good integration with the penis body.
Solution Approach 2:
The patent changes the pressure parameter within the device chamber from atmospheric pressure to negative pressure (vacuum state). This parameter change creates a suction force that naturally secures the device to the penis without requiring mechanical tightening, thereby improving integration and reducing discomfort.
3Extent of automation
If the air vent hole is positioned at the front end of the hard sack, then the valve function is improved, but air may enter from the outside
Solution Approach 1:
The patent positions the air vent hole asymmetrically at the front end of the hard sack rather than at the center or rear. This asymmetric positioning, combined with the valve mechanism, allows controlled air discharge while the deviated position in the soft skin prevents outside air from entering, maintaining the negative pressure state.
Solution Approach 2:
The soft skin acts as an intermediary element with a deviated air vent hole that works in conjunction with the hard sack's air vent hole. This intermediary structure allows the valve function to operate while blocking outside air entry through the deviated position, preventing harmful air infiltration.
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 maintains integration with the penis and reduces discomfort, allowing for natural sexual activity without the need for manual tightening, enhancing the experience for both users.
Implementation Method 1
a hard sack with a shape that simulates an erect penis of a man into which a penis is inserted; and a soft skin made of a silicone rubber that covers the entire outside of the hard sack, by arranging an air vent hole at a front end of the hard sack, and by also arranging an air vent hole at a position that is slightly deviated from the air vent hole at the front end of the soft skin, the device added with a valve function in which while air in the hard sack is discharged to the outside through the air vent hole arranged at the front end of the soft skin from the air vent hole arranged at the front end of the hard sack, the air vent hole arranged at the front end of the hard sack is closed by the soft skin to prevent entry of outside air in a state in which the interior of the hard sack is in a negative pressure

AI summary
Provided is an assistance device comprising a hard sheath that simulates an erect penis and that has on the end thereof an air-bleed hole, and a soft skin that covers the entire hard sheath and that has an air-bleed hole at a position that is slightly offset from the air-bleed hole of the hard sheath, and the device has added thereto a valve function due to the two air-bleed holes.
