Solution Overview

Problem

Current toothpaste formulations and delivery systems fail to effectively control the amount of fluoride and other active ingredients applied during brushing, particularly in children, leading to potential ingestion hazards and non-compliance with oral hygiene routines.

Innovation Solution

A toothpaste delivery kit featuring multiple tubes with unique properties, including a deformable toothpaste tube with a tapered nozzle that regulates the amount of toothpaste dispensed, allowing for controlled application and encouraging proper brushing habits through interactive and customizable flavor and color combinations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If children use flavored toothpaste to encourage brushing, then brushing motivation is improved, but fluoride ingestion risk increases

Engineering Contradiction:
Improvebrushing motivationVSAvoidfluoride ingestion risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical parameters of toothpaste by adjusting viscosity to a specific range (30,000-300,000 cps) and specific gravity (1.20-1.40), causing the toothpaste to extrude in a controlled bead pattern rather than a continuous stream. This parameter modification allows children to apply toothpaste to brush bristles without excessive dispensing, reducing fluoride ingestion risk while maintaining appeal through flavor and color.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The nozzle acts as an intermediary device between the toothpaste tube and the brush, regulating the flow of toothpaste through its specific geometry (conical shape with tapered opening). This intermediary structure controls the amount of toothpaste that reaches the brush, preventing over-application while still providing sufficient product for effective brushing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If adults apply sufficient toothpaste for effective brushing, then cleaning effectiveness is improved, but product waste increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidproduct waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

By modifying the toothpaste's rheological parameters (viscosity and specific gravity) and the nozzle geometry, the system enables precise control over the amount of toothpaste dispensed. This allows adults to apply only the necessary amount for effective brushing without wasting product, as the controlled extrusion prevents excessive dispensing.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The toothpaste tube with regulated nozzle is designed to self-regulate the dispensing amount based on user application pressure. The system automatically controls the flow characteristics through its engineered parameters, eliminating the need for users to manually measure or regulate toothpaste application.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a standard toothpaste tube is used, then ease of use is maintained, but control over application amount is lost

Engineering Contradiction:
Improveease of useVSAvoidapplication amount control
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent modifies the tube's nozzle parameters (conical geometry with specific opening size) and toothpaste physical parameters (viscosity, specific gravity) to achieve controlled extrusion. This maintains ease of use through simple squeezing motion while precision-controlling the application amount through the regulated flow characteristics.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The regulated nozzle serves as an intermediary that translates general user pressure into controlled toothpaste flow. It mediates between the user's simple squeezing action and the need for precise application control, maintaining ease of use while achieving precision in product dispensing.

Inventive Principle:
Principle #24Intermediary (Mediator)
