Solution Overview

Problem

Existing penis extension devices face challenges in reliably securing the penis due to inadequate fastening mechanisms, which often result in difficulty in application and instability during traction.

Innovation Solution

A cuff with a proximal area for contact with the penis shaft and a distal area designed to connect with a hollow body of a penis extension device, featuring a thicker wall thickness in the distal area for stability and resilience, allowing it to absorb forces while remaining elastic and retaining its shape, along with a vacuum system to maintain connection during use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the cuff wall thickness is increased to improve stability and force absorption, then the cuff becomes less flexible and more difficult to apply

Engineering Contradiction:
Improvecuff stabilityVSAvoidease of application
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The cuff is designed with non-uniform wall thickness, having a thicker distal area for stability and force absorption, and a thinner proximal area for flexibility and ease of application. This local variation in material distribution resolves the contradiction by optimizing each region for its specific functional requirements.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The cuff is divided into distinct functional zones: a proximal area with smaller wall thickness for flexibility, and a distal area with larger wall thickness for stability. This segmentation allows each portion to independently fulfill its specific mechanical requirements without compromising the other.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the cuff is made thinner to improve flexibility and ease of application, then the cuff loses stability and ability to absorb forces

Engineering Contradiction:
Improveease of applicationVSAvoidforce absorption capability
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The cuff incorporates locally varied wall thickness where the distal area has increased thickness specifically to provide force absorption capability, while the proximal area maintains reduced thickness for flexibility. This localized material optimization resolves the contradiction between strength and ease of application.

Inventive Principle:
Principle #3Local quality

3Strength

If the cuff is made thicker to improve force absorption, then the cuff becomes stiffer and less elastic

Engineering Contradiction:
Improveforce absorption capabilityVSAvoidelasticity
Core Design Contradiction:
StrengthVSDuration of action of moving object

Solution Approach 1:

The cuff design applies local quality variation where the proximal area has reduced wall thickness to maintain elasticity and flexibility for prolonged wear comfort, while the distal area has increased thickness for force absorption. This spatial differentiation resolves the contradiction between strength and elasticity.

Inventive Principle:
Principle #3Local quality

AI summary

An elastic, tubular cuff (2) is provided, comprising a proximal region (5) for application to a penile shaft and a distal region (6) suitable for externally contacting and enclosing the proximal end of a hollow body (3) of a connecting device (1) for a penile extension device. This cuff (2) is characterized in that the wall thickness of the cuff (2) is greater in the distal region (6) than in the proximal region (5).
