Solution Overview

Problem

Current treatments for premature ejaculation, such as constriction devices, topical anesthetics, and electrical stimulation devices, often negatively impact the user and their partner, require implantation, or come with side effects and complications, failing to effectively delay ejaculation without causing discomfort or desensitization.

Innovation Solution

A non-implantable device that senses anatomical physiological changes to apply transdermal stimulation or confusion to the pudendal nerve, using a cuff with sensors, ultrasound, or electrical generators to delay ejaculation, while preventing cross-exposure to pharmaceutical compounds and maintaining partner comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If constriction devices are used to delay ejaculation, then ejaculation is delayed, but blood pooling causes temperature drop and discomfort

Engineering Contradiction:
Improveejaculation delayVSAvoidtemperature drop and discomfort
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent removes the constriction function entirely from the device, extracting only the electrical stimulation capability. This eliminates the harmful blood pooling effect while preserving the therapeutic benefit of delaying ejaculation through nerve stimulation alone.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical constriction system with an electrical stimulation system. Instead of using physical compression to delay ejaculation, the device uses electrical pulses to stimulate the pudendal nerve, achieving the same therapeutic goal without the harmful mechanical effects.

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

2Duration of action of moving object

If topical anesthetic compounds are applied to treat premature ejaculation, then ejaculation is delayed, but the compound transfers to the partner and desensitizes their sexual organs

Engineering Contradiction:
Improveejaculation delayVSAvoidpartner desensitization
Core Design Contradiction:
Duration of action of moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent replaces chemical topical anesthetics with an electrical stimulation system. This substitution eliminates the transfer and desensitization problem inherent in topical compounds while maintaining the ability to delay ejaculation through controlled nerve stimulation.

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

Solution Approach 2:

The patent introduces electrical stimulation as an intermediary mechanism between the user and the ejaculatory reflex. This intermediary approach allows for precise control of the delay function without the uncontrolled diffusion and transfer problems associated with topical chemical compounds.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Duration of action of moving object

If antidepressants are prescribed to treat premature ejaculation, then ejaculation is delayed, but efficacy decreases over time and serious side effects occur

Engineering Contradiction:
Improveejaculation delayVSAvoidtreatment efficacy and side effects
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The patent replaces pharmacological antidepressant treatment with an electrical stimulation system. This substitution eliminates the tolerance development and serious side effects associated with long-term antidepressant use while providing a reliable, on-demand method for delaying ejaculation.

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

Solution Approach 2:

The patent enables the user to self-administer the treatment through a programmable device that can be controlled independently. This eliminates the need for ongoing pharmaceutical intervention and allows the user to adjust the treatment parameters as needed, providing reliable long-term use without the diminishing efficacy seen with medications.

Inventive Principle:
Principle #25Self-service

4Duration of action of moving object

If implantable electrical stimulation devices are used, then ejaculation is delayed, but surgery complications and infection risks occur

Engineering Contradiction:
Improveejaculation delayVSAvoidsurgery complications and infection
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent removes the implantable component entirely, extracting only the essential electrical stimulation function and delivering it through a non-invasive external device. This eliminates all surgery-related complications and infection risks while maintaining the therapeutic effectiveness of electrical nerve stimulation.

Inventive Principle:
Principle #2Taking out (Extraction)

5Duration of action of moving object

If external electrical stimulation devices with cuffs are used, then ejaculation is delayed, but device complexity increases

Engineering Contradiction:
Improveejaculation delayVSAvoiddevice structure
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The patent removes the constriction cuff component from the device, retaining only the essential electrical stimulation elements. This simplification eliminates the complexity of mechanical expansion and constriction mechanisms while preserving the core therapeutic function of delaying ejaculation through pudendal nerve stimulation.

Inventive Principle:
Principle #2Taking out (Extraction)
