Solution Overview

Problem

Existing treatments for premature ejaculation, such as anesthetic creams, surgical methods, and neuromodulation techniques, are invasive or provide only modest improvements, and there is a need for non-invasive, effective methods to prolong ejaculation time.

Innovation Solution

The use of radiofrequency (RF) or ultrasound (US) neuromodulation devices that apply energy to the dorsal penile nerves and pelvic floor tissue to disrupt neural function, either permanently or temporarily, through the application of RF electrodes or US transducers, respectively, to prolong ejaculation time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If anesthetic creams or surgical methods are used to treat premature ejaculation, then ejaculation time is prolonged, but the treatment becomes invasive with side effects

Engineering Contradiction:

Improveejaculation timeVSAvoidinvasiveness and side effects

Core Design Contradiction:

Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical/invasive treatment methods (creams, surgery) with electromagnetic energy-based neuromodulation (radiofrequency or ultrasound) to achieve non-invasive disruption of neural function in the dorsal penile nerves, thereby prolonging ejaculation time without the harmful effects of invasive procedures

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces electromagnetic energy (radiofrequency or ultrasound) as an intermediary medium to transmit therapeutic effects through the skin and tissue to the target nerves, eliminating the need for direct contact with anesthetic agents or surgical intervention while still achieving neural modulation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Duration of action of moving object

If existing neuromodulation techniques are used, then ejaculation time is prolonged, but the procedures are invasive requiring needle insertion

Engineering Contradiction:

Improveejaculation timeVSAvoidinvasiveness of procedure

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent replaces mechanical needle insertion with non-contact electromagnetic energy delivery systems (surface RF electrodes or ultrasound transducers) that can modulate neural function through the skin, making the procedure non-invasive and easier to perform

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses electromagnetic energy as an intermediary to deliver neuromodulation effects without physical penetration of the skin barrier, replacing the mechanical intermediary of needles with an energy-based transmission medium that achieves the same therapeutic goal non-invasively

Inventive Principle:

Principle #24Intermediary (Mediator)
