Solution Overview

Problem

Current methods for administering drugs to stimulate penis erection, such as injections into the corpora cavernosa or through the urethra, are inconvenient, require precise technique, and risk improper dosing and distribution, leading to unreliable results.

Innovation Solution

An implantable infusion system with long, flexible needles implanted in the body, allowing for controlled and precise delivery of medications directly to the corpora cavernosa, eliminating the need for manual piercing and ensuring accurate dosing through a remotely implanted drive unit and reservoir system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual injection into corpora cavernosa is used, then drug delivery is achieved, but patient convenience deteriorates and dosing precision worsens

Engineering Contradiction:

Improvepatient convenienceVSAvoiddosing precision

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The infusion needle is pre-implanted in the patient's body at the correct location before treatment is needed. This preliminary action eliminates the need for repeated manual injections and ensures the needle is always in the proper position for accurate drug delivery to the corpora cavernosa.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary system consisting of a remotely implanted drive unit and reservoir that controls drug delivery through the pre-implanted needle. This intermediary mechanism ensures precise dosing by controlling the injection process, eliminating the imprecision of manual self-injection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If repeated manual injections are performed, then drug administration is achieved, but reliability of treatment worsens due to improper technique

Engineering Contradiction:

Improvetreatment reliabilityVSAvoidadministration simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The infusion needle is pre-implanted at the correct anatomical location before treatment begins. This ensures that subsequent drug deliveries are always made at the proper site, eliminating the reliability issues caused by improper injection technique in manual methods.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-administration of the drug through the pre-implanted needle via a simple button press on a remote control unit. This maintains treatment reliability through consistent delivery while dramatically improving ease of operation, allowing patients to self-administer without requiring medical supervision.

Inventive Principle:

Principle #25Self-service

3Loss of time

If drug is mixed from dry substance and saline, then medication is prepared, but treatment time increases and convenience deteriorates

Engineering Contradiction:

Improvepreparation timeVSAvoidadministration convenience

Core Design Contradiction:

Loss of timeVSEase of operation

Solution Approach 1:

The drug is pre-mixed with saline solution and stored in the implanted reservoir before treatment is needed. This preliminary preparation eliminates the time-consuming mixing step that would otherwise need to be performed immediately before each injection, reducing both preparation time and administrative complexity.

Inventive Principle:

Principle #10Preliminary action

4Object-affected harmful factors

If injection technique is not precise, then drug delivery occurs, but harmful effects increase due to improper distribution

Engineering Contradiction:

Improveside effects from improper dosingVSAvoidinjection precision

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The remotely implanted drive unit and reservoir system acts as an intermediary that precisely controls drug delivery through the pre-implanted needle. This mechanism ensures accurate dosing and proper distribution to the corpora cavernosa, eliminating the harmful effects caused by imprecise manual injection technique.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical act of manual self-injection with an automated infusion system controlled by a simple button press. This substitution eliminates the variability and imprecision inherent in manual technique while maintaining the ability to deliver the drug to the correct location.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
