Solution Overview

Problem

Existing constrictor rings for maintaining penile erection face challenges in correctly positioning and adjusting to effectively obstruct venous drainage, leading to premature loss of erection, as they lack means to firmly push the ring towards the pubic joint and often fail to protect the urethra.

Innovation Solution

A constrictor ring made of flexible material with adjustable diameter and peripheral loops for precise positioning at the pubic joint, combined with a rigid sleeve to protect the urethra, allowing firm downward pressure to obstruct venous drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a flexible constrictor ring is used to maintain penile erection, then blood can be prevented from escaping the penis, but the ring cannot be firmly positioned against the pubic joint to effectively obstruct venous drainage

Engineering Contradiction:

Improveeffectiveness of venous drainage obstructionVSAvoiddifficulty to correctly position the ring

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The ring is divided into a flexible constrictor portion and a rigid positioning portion (loops), allowing each segment to perform its specific function: the flexible portion constricts while the rigid loops provide firm positioning against the pubic joint

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The ring combines flexible material for constriction with rigid material for the positioning loops, creating a composite structure that simultaneously provides flexibility for blood flow restriction and rigidity for stable positioning against the pubic joint

Inventive Principle:

Principle #40Composite materials

2Reliability

If the constrictor ring is adjusted to exert pressure on venous drainage, then erection can be maintained, but the urethra may be damaged due to lack of protection

Engineering Contradiction:

Improveerection maintenanceVSAvoidurethra damage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A urethral protector element is introduced as an intermediary component between the constrictor ring and the urethra, preventing direct contact and potential damage while allowing the ring to maintain constriction pressure for erection support

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The urethral protector is positioned in advance to prevent potential harmful contact between the ring and urethra before any damage can occur, allowing safe adjustment of constriction pressure

Inventive Principle:

Principle #9Preliminary anti-action

3Reliability

If the ring diameter is fixed, then manufacturing is simplified, but the ring cannot be adjusted to achieve the precise pressure needed for effective venous obstruction

Engineering Contradiction:

Improvevenous drainage obstruction effectivenessVSAvoidadjustment mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The ring transitions from a fixed diameter design to a dynamic, adjustable diameter design, allowing the user to modify the ring size to achieve optimal constriction pressure for effective venous drainage obstruction while maintaining a relatively simple adjustment mechanism

Inventive Principle:

Principle #15Dynamics

AI summary

A constrictor ring made of a flexible but resistant material adapted to surround the entire base circumference of the penis tightly, acting in this way as a constrictor device that prevents blood from escaping from the penis, thus maintaining the erection, wherein the constrictor ring has an adjuster to adjust the diameter of the ring; a grip that allows the user to firmly push the constrictor ring towards the pubic joint in a precise position and with a sleeve made of a rigid material that surrounds the ring in a position that matches the urethra when the ring is correctly placed, thus protecting the urethra against possible damage when the ring is adjusted.
