Solution Overview

Problem

Current vacuum erection devices (VEDs) are rigid, causing discomfort and potential injury due to the need for a rigid cylinder that presses into the skin, leading to vacuum leaks and tissue entrapment, and are ineffective in treating venous occlusive disorders like erectile dysfunction.

Innovation Solution

A soft extension member adapted for use with a rigid therapeutic vacuum cylinder that applies negative pressure to disrupt intracellular actin and microtubule formations, increasing cell expansion and viscoelasticity, and stimulates stem cells, reducing cell stiffness and enhancing tissue elasticity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid vacuum cylinder is used to create vacuum seal, then vacuum seal is achieved, but discomfort and potential injury occur due to pressing into the skin

Engineering Contradiction:
Improvevacuum sealVSAvoiddiscomfort and potential injury
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the rigid vacuum cylinder with a flexible soft cylinder made of elastomeric material. This flexible shell can conform to the contours of the body part while maintaining the vacuum seal, thereby eliminating the pressing discomfort and potential injury caused by rigid structures while preserving the therapeutic vacuum effect.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical parameter of the vacuum cylinder from rigid to soft/flexible. This parameter change allows the device to maintain vacuum seal reliability while reducing the harmful pressing effect on the skin and underlying tissues.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a rigid cylinder is pressed into the skin to achieve vacuum, then vacuum is created, but vacuum leaks occur due to pubic hair or tissue entrapment

Engineering Contradiction:
ImprovevacuumVSAvoidvacuum leaks
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The flexible soft cylinder can adapt to the irregular surface of the body, including pubic hair and tissue contours, creating a more reliable vacuum seal without trapping tissues. The flexibility allows the seal to conform dynamically, preventing vacuum leaks that occur with rigid structures.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If surrounding tissue is pulled into the rigid cylinder, then vacuum is applied, but significant pain and potential injury occur

Engineering Contradiction:
Improvevacuum applicationVSAvoidpain and potential injury
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The flexible soft cylinder prevents surrounding tissue from being pulled into the vacuum chamber because the soft material can deform to accommodate tissue contours without creating sharp edges or rigid surfaces that would trap and injure tissues. This maintains vacuum application reliability while eliminating pain and injury risks.

Inventive Principle:
Principle #30Flexible shells and thin films

4Productivity

If conventional VED is used, then blood is drawn into the penis, but it is ineffective in treating venous occlusive disorders due to cell stiffness

Engineering Contradiction:
Improveblood engorgementVSAvoidtreatment effectiveness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces the conventional mechanical vacuum application with a soft, compliant vacuum system that can apply distributed pressure more effectively. This mechanical substitution allows for better transmission of vacuum force to the tissue, enhancing blood engorgement and simultaneously providing the cellular stretching needed to reduce cell stiffness and treat venous occlusive disorders.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the pressure distribution parameter from concentrated (rigid) to distributed (soft), which enhances both blood engorgement efficiency and cellular mechanical stimulation. This parameter change allows the system to achieve therapeutic effectiveness for venous occlusive disorders while maintaining productivity in blood engorgement.

Inventive Principle:
Principle #35Parameter changes

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 soft extension member provides a comfortable and effective treatment for venous occlusive disorders by creating a vacuum seal without constriction, increasing penile and cavernosal tumescence, and stimulating stem cells for enhanced therapeutic outcomes.

Implementation Method 1

pumping air out of the vacuum chamber from the distal end to create a negative pressure within the vacuum chamber, thereby causing the tissue contacting portion to collapse around the tissue to be treated and create a vacuum seal

Methodology Applied
Scientific EffectVacuum: Vacuum

Implementation Method 2

maintaining the negative pressure within the vacuum chamber for sufficient time to draw blood into the tissue to be treated and achieve a desired state of blood engorgement within the tissue

Methodology Applied
Scientific EffectNegative pressure: Pressure Gradient
