Solution Overview

Problem

Traditional toothpaste tubes fail to control the amount of toothpaste applied during brushing, leading to health risks from excessive ingestion, environmental waste, and inconvenience, especially for children and seniors.

Innovation Solution

A droplet of toothpaste with a dissolvable outer membrane, embedded into the toothbrush bristles, which dissolves with water or saliva to release the toothpaste, eliminating the need for squeezing or swallowing and providing a pre-measured, waste-free, and easy-to-use solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional toothpaste tubes are used, then toothpaste can be dispensed continuously, but the amount of toothpaste applied cannot be controlled leading to excessive ingestion

Engineering Contradiction:
Improveamount of toothpasteVSAvoidcontrol of toothpaste application
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The toothpaste is divided into individual single-use droplets, each containing a pre-measured amount. This segmentation allows precise control of the quantity applied while eliminating the risk of excessive ingestion, as each droplet represents a controlled dose that can be easily monitored.

Inventive Principle:
Principle #1Segmentation

2Loss of substance

If traditional toothpaste tubes are used, then toothpaste can be stored and reused, but waste and mess occur due to inability to control the amount used

Engineering Contradiction:
Improvetoothpaste wasteVSAvoidtoothpaste delivery system
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The invention uses disposable single-use droplets instead of reusable tubes. Each droplet is designed for one-time use, eliminating waste from partially used tubes and mess from squeezing. The simplicity of the disposable droplet design reduces the complexity of delivery systems while minimizing substance loss.

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

3Quantity of substance

If capsules containing toothpaste are used, then the amount can be pre-measured, but the capsules cannot hold onto the brush and require adapted delivery systems

Engineering Contradiction:
Improvepre-measured toothpasteVSAvoidcompatibility with toothbrush
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The droplet uses a flexible membrane shell that can deform to fit into the bristles of any toothbrush. This thin film structure allows the pre-measured toothpaste capsule to adapt to different toothbrush types without requiring specialized delivery systems, maintaining both precise measurement and universal compatibility.

Inventive Principle:
Principle #30Flexible shells and thin films

4Reliability

If fluoride-containing toothpaste is used, then dental cavities are prevented, but health risks occur from excessive ingestion

Engineering Contradiction:
Improvecavity preventionVSAvoidingestion risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By segmenting toothpaste into individual droplets with pre-measured fluoride content, the invention maintains the cavity-prevention benefits of fluoride while eliminating the harm of excessive ingestion. Each droplet contains a safe, controlled amount that can be easily monitored, ensuring reliable protection without toxic exposure.

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 droplet system ensures the right amount of toothpaste is used for each brushing, reducing ingestion risks, minimizing waste, and being convenient for all users, including children and seniors, while being adaptable to any toothbrush type.

Implementation Method 1

the outer membrane is formed from dissolvable film strip technology which, in use, dissolves when water is poured on the droplet, to release the toothpaste therein
