Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing erectile dysfunction devices are cumbersome and inadequate for severe cases, failing to effectively maintain erections.
Innovation Solution
An annular inflatable constriction ring that forms an airtight system with a vacuum erection device to restrict venous outflow, maintaining erections by inflating at the penis base after vacuum-induced erection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing constriction devices are used to maintain erection, then venous outflow is restricted, but the devices are cumbersome and inadequate for severe cases
Solution Approach 1:
The inflatable constriction ring is nested within the vacuum erection device chamber, allowing the ring to be stored and deployed within the same device structure. This integration eliminates the need for separate constriction devices and reduces overall system complexity while maintaining effective venous outflow restriction.
Solution Approach 2:
The constriction ring is inflatable through pneumatic means using the vacuum pump to inflate the ring after erection is achieved. This allows for controlled, gradual constriction that is more comfortable and effective than rigid constriction devices, while using the same pump mechanism already present in the VED.
2Device complexity
If constriction devices are made simpler, then device complexity is reduced, but they fail to effectively maintain erections in severe cases
Solution Approach 1:
The vacuum erection device is designed to perform multiple functions: creating vacuum for erection induction and then inflating the constriction ring for erection maintenance. This multi-functionality eliminates the need for separate constriction devices while providing effective treatment for both mild and severe erectile dysfunction cases.
Solution Approach 2:
The constriction ring transitions from a deflated state during vacuum application to an inflated state for constriction maintenance. This dynamic transformation allows the device to adapt to different phases of the treatment process, providing both simplicity and effectiveness without requiring multiple separate devices.
3Reliability
If the constriction ring is inflated to restrict venous outflow, then erection is maintained, but the system must be airtight which increases device complexity
Solution Approach 1:
The inflatable constriction ring and vacuum chamber are merged into a single integrated system. The same chamber that creates the vacuum for erection induction also houses and inflates the constriction ring. This merging eliminates the need for separate airtight systems while maintaining effective venous outflow restriction through the inflated ring.
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 effectively maintains erections by restricting venous outflow, addressing the inadequacies of existing devices, particularly in severe cases.
Implementation Method 1
activation of vacuum erection device induces erection
Implementation Method 2
the constriction ring is inflated that constricts the base of penis to restrict venous outflow thus maintaining erection

AI summary
The apparatus described is an inflatable constriction ring device to constrict the venous outflow from penis. The inflatable constriction ring is used in combination with vacuum erection device (VED), which induces erection and the ring constricts the venous outflow at the base of the penis to maintain erection.The distal end of constriction ring device is mountable on the proximal end of vacuum erection device to make a sealable contact with the vacuum erection device. The constriction ring is configured to make sealable contact with the user's skin around the penis thus creating an airtight system. The constriction ring is attached to the tubing of the inflation/deflation pump, which is used to inflate the constriction ring.
