Inflatable Penile Ring with Rigid Support for Erection Sustainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum tube systems for inducing and sustaining erections are cumbersome and inefficient, with inflatable rings often being too large and directing air pressure throughout the ring rather than directly against the penis, leading to ineffective erection maintenance.
Innovation Solution
A penile erection system comprising a vacuum assembly with an annular inflatable bladder and a rigid ring support, where the bladder is inflated to radially constrict the penis, using a one-way valve and fluid pump to control pressure, ensuring the pressure is directed inwardly to maintain the erection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If an inflatable ring is used to maintain erection, then the erection can be sustained, but the ring becomes too large and cumbersome when inflated
Solution Approach 1:
The ring assembly is segmented into three main components: a rigid support ring, an inflatable bladder, and a valve mechanism. This segmentation allows the bladder to be inflated only to the extent needed for maintaining erection without requiring the entire ring structure to expand proportionally, thus sustaining erection while limiting overall ring size.
Solution Approach 2:
The inflatable bladder is positioned to contact only the specific area of the penis base where compression is needed to maintain erection. The rigid support ring provides structural containment while the bladder applies localized pressure, ensuring effective erection sustainment without requiring uniform expansion of the entire ring assembly.
2Stress or pressure
If air pressure is directed throughout the ring, then the ring can be inflated, but the pressure is not directed directly against the penis where it is needed
Solution Approach 1:
The bladder is designed to contact the penis base at specific locations where compression is most effective for maintaining erection. When inflated, the bladder directs pressure locally against the penis rather than distributing it uniformly throughout the entire ring structure, ensuring reliable erection maintenance.
Solution Approach 2:
The rigid support ring acts as an intermediary between the inflatable bladder and the external environment. It contains the bladder and directs the pressure generated by bladder inflation specifically against the penis base, ensuring that pressure is applied where needed rather than dispersing throughout the entire ring structure.
3Device complexity
If a simple elastic ring is used, then the device is simple, but it is less effective due to variation in penis size
Solution Approach 1:
The ring assembly transitions from a static elastic ring to a dynamic inflatable structure. The bladder can be inflated to different volumes and pressure levels, allowing the device to adapt to variations in penis size and shape. This dynamic adjustment capability maintains effectiveness across different users while keeping the base structure relatively simple.
Solution Approach 2:
The inflatable bladder allows users to adjust the pressure and volume parameters to match their specific anatomical requirements. This parameter adjustability compensates for variations in penis size and shape, maintaining erection sustainment effectiveness without requiring complex sizing options or multiple ring sizes.
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 system effectively induces and sustains erections by directing pressure inwardly against the penis, using a bladder that expands radially to constrict blood flow, providing a stable and comfortable solution for erectile dysfunction.
Implementation Method 1
The tube is connected to a vacuum source such as an air pump. A flaccid penis is inserted into the chamber via the open end of the tube, which is then pressed to the abdomen to provide an airtight seal. The user actuates the vacuum pump and evacuates air from within the chamber of the vacuum tube. The negative pressure created in the chamber around the penis draws blood into the penis creating an erection.
Implementation Method 2
The inner surface of the bladder forms a central circular opening adapted for receiving the penis. Expansion of the bladder causes the inner surface of the bladder to expand while being substantially fixed by the ring support against outwardly radial deformation. A compressive force is thus introduced around the surface of the penis for constricting blood flow from the penis in order to maintain the erection.

AI summary
A system for inducing and sustaining an erection of a penis a vacuum assembly and a ring assembly adapted to encircle the penis. An inflatable ring assembly disposed in an outwardly flared proximal end of the tube. The ring assembly forms a central circular opening adapted for receiving the penis. A rigid annular ring support is disposed within the ring. A fluid pump is selectively coupled to a valve in the ring assembly, and the pump is adapted to introduce the bladder-inflating fluid under pressure. Expansion of the ring assembly causes the inner surface of the ring assembly to expand while being substantially fixed by the ring support against outwardly radial deformation. A compressive force is thus introduced around the surface of the penis for constricting blood flow from the penis sustain the erection.
