Variable Thickness Cuff for Penile Extension Stability
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
3Strength
If the cuff is made thicker to improve force absorption, then the cuff becomes stiffer and less elastic
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.

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).
