Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing intravaginal conception assistance devices are uncomfortable and potentially traumatic to insert, can cause pain, and may intimidate users due to their rigid shafts and intimidating size, which can lead to discomfort and stress during use, affecting fertility chances.

Innovation Solution

A substantially invertible cup part that can be folded inside out for easy insertion and painless removal, combined with a flexible handling element and semen-friendly moisturizer to facilitate comfortable use and improve sperm delivery to the cervix.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid shaft is used to provide structural support and positioning capability, then the device can maintain its shape and position accurately, but it causes discomfort and potential trauma to vaginal walls during insertion and prolonged use

Engineering Contradiction:

Improvepositioning accuracyVSAvoidtrauma to vaginal walls

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies this principle by replacing the rigid shaft with a flexible catheter that can be covered with elastically deformable material. The flexible catheter maintains the necessary structural support while adapting to the vaginal canal's contours, eliminating trauma to vaginal walls during insertion and use.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the physical parameter of rigidity by using elastically deformable material that can flex inwards to some extent. This material parameter change allows the device to maintain positioning accuracy while becoming comfortable for prolonged use, as the flexible material adapts to the vaginal environment.

Inventive Principle:

Principle #35Parameter changes

2Shape

If a rigid shaft is used to provide structural support, then the device maintains its shape, but it creates an intimidating appearance that causes psychological discomfort to users

Engineering Contradiction:

Improvestructural integrityVSAvoiduser comfort and confidence

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The flexible catheter covered with elastically deformable material provides a non-intimidating appearance while maintaining structural integrity during use. The flexibility allows the device to adapt to the vaginal canal without creating an intimidating rigid structure visible to the user.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The device transitions from a static rigid structure to a dynamic flexible structure that adapts to the vaginal environment. This dynamic behavior makes the device less intimidating as it conforms to the user's anatomy rather than imposing a rigid form.

Inventive Principle:

Principle #15Dynamics

3Quantity of substance

If the device is made larger to improve collection capacity, then more ejaculate can be collected and presented to the cervix, but it increases discomfort and difficulty in insertion

Engineering Contradiction:

Improveejaculate collection capacityVSAvoidinsertion ease

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The flexible catheter allows the device to be inserted in a compressed state and then expand within the vaginal canal to its full collection capacity. This dynamic expansion enables adequate ejaculate collection without increasing insertion difficulty, as the flexible material can be compressed during insertion and then expands to provide sufficient capacity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The flexible catheter can be compressed into a smaller form factor for insertion, similar to nesting, and then expands within the vaginal canal to provide adequate collection capacity. This allows the device to have sufficient capacity without requiring a large insertion profile.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Ease of operation

If the cup part is made invertible to facilitate easy insertion and removal, then user comfort is improved, but the device complexity increases

Engineering Contradiction:

Improveinsertion and removal easeVSAvoidstructural complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The invertible cup part uses dynamic flexibility to achieve easy insertion and removal without complex mechanical structures. The elastically deformable material allows the cup to be compressed for insertion and then expands to its full shape for collection, providing ease of operation through material flexibility rather than mechanical complexity.

Inventive Principle:

Principle #15Dynamics

AI summary

An intravaginal conception assistance device for collecting and presenting ejaculate relatively close to a cervix. The device has a cup part for collecting the ejaculate present in a vaginal canal and presenting it relatively close to the cervix upon moving through the vaginal canal towards the cervix. The cup part is substantially invertible. The cup part can be brought from a first, substantially non-inverted state into a second, substantially inverted state in which the cup part has been folded substantially inside out. As a result, insertion of the cup part into the vaginal canal can be facilitated.
