Time-Release Lubrication Capsule for Sustained Vaginal Moisture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vaginal lubricants require immediate application, can be messy, and do not provide long-lasting relief for users experiencing vaginal dryness, especially those going through menopause or dealing with medical conditions.
Innovation Solution
A time-release vaginal lubrication capsule device made of biodegradable polymers that dissolves in response to body heat, releasing lubricant gradually and optionally with multi-layered designs for phased delivery, containing water-based lubricants with soothing agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional vaginal lubricants are applied immediately before intimacy, then lubrication is provided, but it requires direct application by the user which is messy and inconvenient
Solution Approach 1:
The capsule device is designed to self-dissolve and self-release lubricant when inserted into the vagina, eliminating the need for manual application. The body's natural heat triggers the dissolution process, and the lubricant is automatically released without user intervention, making the process clean and convenient.
Solution Approach 2:
The capsule acts as an intermediary carrier that holds the lubricant and delivers it automatically. Instead of applying lubricant directly with hands, the capsule serves as a mediator that releases the lubricant in a controlled manner through dissolution, preventing direct contact and mess.
2Duration of action of moving object
If traditional lubricants are applied, then immediate lubrication is achieved, but it requires frequent reapplication and does not provide long-lasting relief
Solution Approach 1:
The lubricant is pre-loaded into the capsule in advance. The capsule is designed to dissolve gradually over time, releasing the lubricant in a sustained manner. This preliminary preparation allows for extended duration of action without requiring frequent reapplication, as the entire lubricant supply is contained and released systematically.
Solution Approach 2:
The capsule dissolution and lubricant release occur in a controlled, periodic manner rather than all at once. The multi-layered capsule structure ensures that lubricant is released at different rates from different layers, providing sustained and consistent lubrication over an extended period.
3Duration of action of moving object
If a single-layer capsule is used, then the device is simple, but it cannot provide phased or extended-release of lubricant
Solution Approach 1:
The capsule is divided into multiple layers, with each layer containing lubricant and designed to dissolve at different rates. This segmentation allows for phased release of lubricant over time. The varying thicknesses and compositions of different layers create a complex but controlled release pattern that extends the duration of action.
Solution Approach 2:
The capsule utilizes composite materials with different dissolution properties in each layer. By combining materials with varying degradation rates, the capsule achieves extended and phased lubricant release. This composite structure increases device complexity but enables sophisticated control over the release timeline.
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
Provides sustained vaginal lubrication without direct application, reducing mess and irritation, and enhancing user comfort and vaginal health with controlled release and absorption.
Implementation Method 1
The capsule is made of a biocompatible, heat-sensitive, and dissolvable polymer. Upon reaching a heating threshold within the vagina, the polymer dissolves in a controlled manner, allowing the release of a lubricant stored within the capsule.
Implementation Method 2
The capsule, made from biodegradable polymers such as poly (lactic-co-glycolic acid) (PLGA), dissolves at a controlled rate, releasing the lubricant stored within.

AI summary
A time-release vaginal lubrication capsule device is provided. The device is comprised of a capsule designed to release lubricant gradually when exposed to body heat. The capsule, made from biodegradable polymers such as poly (lactic-co-glycolic acid) (PLGA), dissolves at a controlled rate, releasing the lubricant stored within. The dissolution rate can be adjusted by varying the thickness or using multi-layer designs for phased release. Lubricant options include water-based formulas, some with micro-encapsulated beads for extended-release. Additional features include the incorporation of soothing agents, flavors, and scents, as well as a syringe for insertion and a sterilization cylinder for cleaning.
