Solution Overview

Problem

Existing sex enhancers, such as penis extenders and intravaginal devices, fail to provide pleasurable contact with the cervix during sexual intercourse while maintaining the man's pleasure, often being cold, hard, or the wrong shape and size, leading to reduced enjoyment for women.

Innovation Solution

A flexible and deformable fluid-filled enclosure with a smooth exterior surface, made of elastomeric materials, is inserted into the vagina to be pushed against the cervix by the penis, providing enhanced pleasure without detracting from the man's experience, with a rounded shape and suitable size to conform to the vaginal canal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If penis extenders are used to reach the cervix, then the length of the penis is increased, but the pleasure of the woman is reduced because the extender is cold, hard, and eliminates contact between the head of the penis and the inner wall of the vagina

Engineering Contradiction:
Improvelength of penisVSAvoidpleasure of woman
Core Design Contradiction:
Length of moving objectVSEase of manufacture

Solution Approach 1:

The patent introduces an intermediary device (cervical contact device) that mediates between the penis and the cervix. This device is specifically designed to be body temperature, soft, and flexible, allowing it to transmit warmth and pressure sensations while maintaining the ability to reach the cervix. The intermediary device includes a distal end that contacts the cervix and a proximal end that contacts the penis, creating a bridge that preserves pleasure while enabling cervical contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical parameters of the cervical contact device to match human tissue characteristics. The device is maintained at body temperature (37°C), has a soft and flexible consistency similar to human tissue, and features a rounded distal end with a diameter of about 0.5 to 2 cm. These parameter changes ensure the device provides pleasurable sensations while effectively contacting the cervix.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If intravaginal devices are used to contact the cervix, then the cervix can be stimulated, but the devices are cold, hard, and of the wrong shape or size to provide pleasure

Engineering Contradiction:
Improvecervical stimulationVSAvoidtemperature of device
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The patent specifically addresses the temperature parameter by designing the cervical contact device to be maintained at body temperature (37°C). The device includes thermal insulation features and is made from materials with appropriate thermal properties to retain body temperature during use. This parameter change eliminates the cold sensation that plagues conventional intravaginal devices while preserving effective cervical stimulation.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If intravaginal devices are used to contact the cervix, then cervical contact is achieved, but the devices are hard and of the wrong shape to provide pleasure

Engineering Contradiction:
Improvecervical contactVSAvoidhardness of device
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent changes the hardness parameter of the cervical contact device to match the softness of human tissue. The device is made from flexible, compliant materials that can deform and adapt to the vaginal canal and cervix geometry. The distal end features a rounded shape with a diameter of about 0.5 to 2 cm, and the overall device has a flexible construction that allows it to conform to anatomical structures, providing pleasurable contact rather than harsh, rigid stimulation.

Inventive Principle:
Principle #35Parameter changes

4Length of moving object

If penis extenders are used, then the penis appears longer and thicker, but they detract from the man's pleasure because they eliminate contact between the head of the penis and the inner wall of the vagina

Engineering Contradiction:
Improveapparent length of penisVSAvoidloss of pleasurable contact
Core Design Contradiction:
Length of moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent segments the cervical contact function from the penis itself, using a separate, dedicated device that interfaces between the penis and cervix. This segmentation allows the penis to maintain its natural characteristics and pleasurable contact with the vaginal wall, while the intermediary cervical contact device specifically handles the cervical stimulation function. The segmented design preserves the natural sensory experience for the man while adding the desired cervical contact capability.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The sex enhancer effectively enhances pleasure for women by providing gentle pressure against the cervix while maintaining the man's pleasure, being safe, easy to use, and reusable, with a design that conforms to the vaginal shape and maintains temperature for optimal experience.

Implementation Method 1

The sex enhancer is adapted for heating and insertion into the vagina before sexual intercourse

Methodology Applied
Scientific EffectThermal conduction: Conduction (thermal)

AI summary

A sex enhancer is a flexible and deformable fluid-filled enclosure with a smooth exterior surface having a rounded shape. The sex enhancer is heated and inserted into the vagina before sexual intercourse. During sexual intercourse, the penis pushes the sex enhancer against the cervix to provide enhanced pleasure to the woman without detracting from the pleasure of the man.
