Stretchable Ring and Tether Device for Erection Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for erectile dysfunction, such as PDE5 inhibitors and constriction rings, have limitations including adverse reactions, high costs, and reduced effectiveness due to blood flow issues and discomfort, while existing devices for foreskin restraint do not adequately enhance penile stimulation.
Innovation Solution
A device comprising a stretchable ring and tether system that restricts blood flow from the penis base, maintains penile skin retraction, and enhances frictional stimulation, preventing lateral movement and optimizing glans exposure, thereby promoting and maintaining erections and enhancing sexual pleasure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a penis ring is made very tight to improve functionality and restrict blood flow, then erection effectiveness is improved, but discomfort and risk of injury increase
Solution Approach 1:
The patent changes the physical parameters of the constriction device by using a stretchable material with elastic properties, allowing the ring to exert controlled constriction force without being excessively tight. The elastic modulus and stretchability are optimized to maintain blood flow restriction for erection effectiveness while preventing discomfort and injury through material property adjustment.
Solution Approach 2:
The patent employs a flexible stretchable ring made of elastic material that can conform to the penis shape and provide gentle, distributed pressure. This flexible structure replaces rigid or overly tight constriction mechanisms, achieving blood flow restriction through elastic deformation rather than rigid compression, thereby reducing discomfort and injury risk.
2Ease of operation
If a penis ring allows longitudinal movement along the shaft to improve comfort, then ease of operation is improved, but blood flow restriction effectiveness is reduced
Solution Approach 1:
The patent combines the penis ring with a tether that anchors the ring to the scrotum, merging two functional elements (constriction ring + anchoring tether) into a unified system. This combination prevents longitudinal movement of the ring along the shaft while maintaining comfort, as the tether provides stable positioning without requiring the ring itself to be rigid or overly tight.
Solution Approach 2:
The tether acts as an intermediary element between the penis ring and the scrotum, mediating the positioning function. Instead of making the ring itself rigid to prevent movement (which would cause discomfort), the tether serves as the positioning mechanism, allowing the ring to remain flexible and comfortable while still preventing longitudinal migration through the anchoring action of the tether.
3Ease of operation
If the foreskin is allowed to slide freely over the shaft during sexual stimulation, then natural stimulation is maintained, but direct frictional stimulation of the glans is reduced
Solution Approach 1:
The patent extracts the foreskin from its natural sliding position over the glans by retracting it behind the penis using the stretchable ring mechanism. This separation removes the foreskin's interference with direct glans-stimulating contact, allowing the glans to be directly exposed to frictional stimulation from the vaginal wall or stimulating object while the foreskin remains in a retracted, non-interfering position.
Solution Approach 2:
The device performs preliminary action by automatically retracting and holding the foreskin in a retracted position before sexual stimulation begins. This preliminary retraction ensures that the glans is fully exposed and ready for direct stimulation without the need for manual foreskin retraction during the act, maintaining both natural stimulation and optimal glans contact from the outset.
4Reliability
If PDE5 inhibitors are used to treat erectile dysfunction, then erection capability is improved, but adverse drug reactions and drug interactions occur
Solution Approach 1:
The patent employs a mechanical, non-pharmacological device (stretchable ring with tether) that provides erection support through physical constriction and blood flow restriction rather than chemical intervention. This disposable-like mechanical solution replaces PDE5 inhibitors, avoiding all associated adverse drug reactions and drug interactions while providing reliable erection enhancement through purely mechanical means.
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 provides a more reliable, harder, and longer-lasting erection by efficiently trapping blood, stimulating nerve endings, and increasing frictional sensation, while preventing discomfort and reducing foreskin interference during intercourse.
Implementation Method 1
the ring restricts blood flow out of the penis when the device is worn during sexual activity
Implementation Method 2
the tether may be sized and shaped such that, when stretched, the tether reaches from the base of the scrotum backward across the perineum, upward between the buttocks and to the base of the spine

AI summary
A device for treatment of erectile dysfunction is disclosed herein. The device has a stretchable ring to retract and maintain the foreskin of the penis a throughout sexual activity, and a stretchable tether coupled to the ring. An anchor end of the tether is mountable at a tailbone of the user, causing the tether to pull on the ring. The device is operative to increase the length of the sliding interface of the penis during sexual activity. The device operative to stimulate the stretch-sensitive nerve endings of the foreskin before and during sexual activity. The device increases stimulation of the sensitive nerve endings of the glans during sexual activity. The device retains blood within the penis upon erection, increasing the ability of the user to maintain an erection for a longer period and to achieve an erection more reliably. The device further increases the appearance of a larger penis.
