Solution Overview

Problem

Existing male chastity devices cause discomfort due to full enclosure of the penis, leading to friction, crumpling, and weight issues, and require lubrication, which can be inconvenient and embarrassing.

Innovation Solution

A male chastity device design featuring a first loop, a second loop, a cup, and a hinging mechanism that encircles the penis and scrotum without fully enclosing the penis, allowing for rotation and a removable fixing mechanism to prevent removal, thereby reducing friction and weight while maintaining circulation and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the whole penis is enclosed within a housing, then the chastity device prevents sexual acts, but the device causes discomfort, friction, and weight issues

Engineering Contradiction:
Improveprevention of sexual actsVSAvoiddiscomfort and friction
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device is divided into separate functional components: a first loop for encircling the base of the penis, a second loop for encircling the glans, and a cup for enclosing the glans. This segmentation allows each component to perform its specific function without unnecessarily enclosing the entire penis, reducing friction and discomfort while maintaining effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the enclosure function from a single comprehensive housing and distributes it across multiple separate loops and cups. The first loop encircles the base, the second loop encircles the glans, and the cup encloses the glans, thereby removing the harmful effect of full enclosure while preserving the preventive function.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If the housing is enlarged to reduce friction and prevent crumpling, then the penis is held securely, but the device becomes easily noticeable under clothing

Engineering Contradiction:
Improvefriction and crumplingVSAvoidvisibility under clothing
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

Instead of enlarging the entire housing, the invention applies enclosure only where necessary: the first loop encircles the base of the penis, the second loop encircles the glans, and the cup encloses the glans. This localized enclosure prevents friction and crumpling at critical points without increasing the overall device size that would be visible under clothing.

Inventive Principle:
Principle #3Local quality

3Reliability

If the device fully encloses the penis, then the chastity function is achieved, but circulation and dryness are compromised

Engineering Contradiction:
Improvechastity functionVSAvoidcirculation and dryness
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device segments the enclosure into discrete loops and cups that can be positioned at specific locations on the penis. The first loop encircles the base, the second loop encircles the glans, and the cup encloses the glans, leaving the shaft exposed. This segmentation maintains circulation and dryness on the exposed portions while preserving the chastity function through the enclosed portions.

Inventive Principle:
Principle #1Segmentation

AI summary

A male chastity comprises a first loop, a cup, a second loop hinged to the first loop and optionally to the cup, and a removable fixing mechanism. The first loop is configured for being traversed by the user's penis and scrotum, and for encircling the penis behind the scrotum. The second loop is configured for being traversed by at least the penis, and for encircling the penis ahead of the scrotum, so that the user's testicles are located between the first loop and second loop. The cup is configured for enclosing at least a head of the penis. The removable fixing mechanism is configured, when joined to the device, for preventing removal of the device form the penis by limiting or blocking relative rotation between the first loop and the second loop, and, if needed, by limiting or blocking relative rotation between the cup and the second loop.
