Solution Overview

Problem

Existing penile prostheses require significant effort to change configurations from flaccid-like to erect-like states, and vice versa, due to complex activation mechanisms.

Innovation Solution

A penile implant design featuring a base portion, an extending portion, and an articulating portion, where the extending portion can be easily transitioned between a short and a lengthened configuration, and the articulating portion can be configured in curved or linear positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex activation mechanisms are used to change configurations, then the implant can be disposed in multiple configurations, but the effort required to change configurations increases significantly

Engineering Contradiction:

Improveconfiguration change capabilityVSAvoideffort to change configuration

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The extending portion is divided into multiple segments (first extending portion, second extending portion, third extending portion) that can move independently relative to each other. This segmentation allows the implant to achieve multiple configurations through simpler individual segment movements rather than complex overall mechanism activation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The implant incorporates movable connections between the extending portion and articulating portion, allowing dynamic reconfiguration. The articulating portion can rotate and move relative to the extending portion, enabling transition between different configurations without complex fixed mechanisms.

Inventive Principle:

Principle #15Dynamics

2Length of moving object

If the extending portion is made longer to accommodate lengthened configuration, then the erect-like state is achieved, but the device size increases

Engineering Contradiction:

Improvepenis length in erect stateVSAvoidimplant size in flaccid state

Core Design Contradiction:

Length of moving objectVSLength of stationary object

Solution Approach 1:

The extending portion segments are designed to nest within each other when in the retracted position. The second extending portion can be positioned within the first extending portion, and the third extending portion within the second, creating a compact nested structure that minimizes the implant size in flaccid state while allowing full extension for erect state.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

According to an aspect, a penile implant includes a base portion, an extending portion, and an articulating portion. The extending portion being configured to be placed in a first configuration and a second configuration. The extending portion having a first length when the extending portion is in its first configuration. The extending portion having a second length when the extending portion is in its second configuration. The second length being greater than the first length.
