Solution Overview

Problem

Current sexual aid devices fail to effectively prevent collision dyspareunia by guiding the penis away from the cervix during intercourse, often exacerbating pain or causing unnatural sensations, and lack design features for secure positioning and easy removal.

Innovation Solution

A cervical shield device with a main body and cervical void, optionally featuring arms, protrusions, grooves, stiffeners, clitoral exciters, textures, and stimulation devices, made of elastomeric material, designed to self-align and self-retain on the cervix, creating a channel for the penis and providing comfort and urinary incontinence relief.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pessary presses against the vaginal wall to self-retain, then the device can be retained without additional mechanisms, but it does not cradle the cervix and does not create a channel to guide the penis away from the cervix

Engineering Contradiction:

Improvedevice retentionVSAvoidcervix guidance and channel creation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device is divided into distinct functional segments: a retention ring that presses against the vaginal wall for self-retention, and a cervix-cradling portion with a channel that guides the penis away from the cervix. This segmentation allows each part to perform its specific function effectively.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the device have different properties: the retention ring is designed to press against the vaginal wall for secure retention, while the cervix-cradling portion is shaped to comfortably hold the cervix and create a guiding channel. Each local region is optimized for its specific function.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If a device occupies space within the vagina to prevent penetration, then deeper penetration is restricted, but it exacerbates pain in the pelvic area instead of guiding the penis away from the cervix

Engineering Contradiction:

Improvecollision dyspareunia preventionVSAvoidpelvic pain exacerbation

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The device acts as an intermediary structure between the penis and the cervix. Instead of allowing direct contact that causes pain, the device creates a channel that redirects the penis away from the cervix, mediating the interaction to prevent harmful collision while enabling comfortable penetration.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device converts the potentially harmful direct impact on the cervix into a beneficial guided path. By creating a channel structure, the device transforms what would be a painful collision into a comfortable guided penetration that avoids the cervix entirely.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Device complexity

If a stimulation device does not extend past the anterior fornix, then the device structure is simpler, but it does not cradle the cervix in a void of material nor does it channel the penis away from colliding with the cervix

Engineering Contradiction:

Improvedevice structureVSAvoidcervix cradling and penis channeling

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The device extends past the anterior fornix into the cervical region, segmented into a retention portion in the vaginal canal and a cervix-cradling portion that extends further. This extension and segmentation enable the device to perform the additional function of cradling the cervix and creating a guiding channel.

Inventive Principle:

Principle #1Segmentation

4Reliability

If a prosthesis applies additional pressure to the cervix to retain the device, then the device remains in place, but it irritates the cervix and causes shifting of the prosthesis about the cervix

Engineering Contradiction:

Improvedevice positioning stabilityVSAvoidcervix irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device uses a flexible, compliant material that can adapt to the cervix shape. Instead of applying rigid pressure that causes irritation, the flexible material cradles the cervix gently while maintaining device position, eliminating both irritation and shifting.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A sexual aid device comprising a main body (100) and a cervical void (110), sized and shaped to shield a cervix (350) during intercourse. This self-retaining device comprises a means to prevent a penis from colliding with the cervix (350), a means to shield the anterior vagina wall from frictional contact during sexual intercourse and at least one means to retain the sexual aid device within the vagina. This device provides a non-surgical, cost-effective solution to allow for more comfortable deeper penetration by guiding the penis away from the cervix.
