Solution Overview

Problem

Current vaginal care applicators often require separate dispensers, can be messy, and may not effectively treat both vaginal introitus and external tissues, with issues such as leakage, need for precise orientation, and hygiene concerns, leading to an unpleasant user experience and reduced adoption.

Innovation Solution

A tapered applicator with multiple dispensing openings and a reservoir storing 10g to 200g of vaginal care composition, allowing for easy application to both vaginal introitus and external tissues without the need for a separate dispenser, and featuring a design that prevents leakage and contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate dispenser is used with the applicator, then the composition can be delivered, but the device complexity increases and usage becomes messier

Engineering Contradiction:
Improveease of applicationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the dispenser and applicator into a single integrated unit. The applicator shaft serves as both the delivery vehicle and the dispensing mechanism, with openings in its distal end allowing composition to be dispensed directly during insertion. This eliminates the need for separate dispensers and reduces overall device complexity while maintaining ease of application.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If plunger type applicators are used to deliver composition deep into the vaginal canal, then the composition can be delivered effectively, but leakage occurs and hygiene is compromised

Engineering Contradiction:
Improvedelivery effectivenessVSAvoidleakage and contamination
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The applicator is designed with multiple discrete openings distributed along its distal end rather than a single centralized delivery point. This segmentation allows the composition to be dispensed in a controlled manner along the vaginal wall, preventing leakage while maintaining effective delivery. The tapered configuration further segments the delivery path to match the anatomical curvature.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The applicator is designed as a single-use disposable device. This eliminates the need for cleaning and reduces hygiene concerns associated with reusable applicators. The disposable nature ensures that each use is clean and free from contamination, while the low cost encourages consistent use.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If over-the-counter plunger type applicators are used, then composition can be delivered, but precise orientation is required which makes usage difficult

Engineering Contradiction:
Improvedelivery accuracyVSAvoidease of application
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The applicator features an asymmetric tapered configuration that is wider at the proximal end and narrower at the distal end. This asymmetric design provides natural guidance during insertion, allowing the user to insert the applicator at various angles without requiring precise orientation. The tapering shape ensures proper alignment as it is inserted, eliminating the need for careful positioning while maintaining delivery accuracy.

Inventive Principle:
Principle #4Asymmetry

4Reliability

If applicators applying composition only to the vaginal canal are used, then the vaginal canal can be treated, but external vaginal tissues are not treated

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidtreatment coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The applicator design extends treatment from the internal vaginal canal dimension to the external vaginal tissue dimension. The distal openings are positioned to allow composition to be dispensed both inside the vaginal canal and on the external vaginal tissues during insertion. This multi-dimensional approach ensures comprehensive treatment of both internal and external areas affected by vaginal conditions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
