Solution Overview

Problem

Existing oral care compositions face challenges in evenly distributing gingerdiol, making it difficult to achieve consistent antibacterial and anti-inflammatory effects in oral hygiene products.

Innovation Solution

A process involving the synthesis of gingerdiol and its even distribution within an oral care composition by adding it to a polyol mixture with less than 5 wt% water, followed by incorporation into a liquid base composition, preferably with silica and other ingredients, to create a stable and effective dentifrice or toothpaste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If gingerdiol is added directly to the oral care composition, then the composition can be formulated, but the gingerdiol cannot be evenly distributed throughout the product

Engineering Contradiction:
Improveeven distribution of gingerdiolVSAvoiddifficulty of incorporation
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent uses a polyol (such as glycerol, propylene glycol, or sorbitol) as an intermediary medium to dissolve gingerdiol before incorporating it into the oral care composition. This mediator allows the gingerdiol to be evenly distributed throughout the final product, solving the distribution problem while maintaining ease of manufacture.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs a preliminary action by pre-dissolving gingerdiol in a polyol to create a concentrate solution before adding it to the oral care composition. This preliminary step ensures uniform distribution of gingerdiol throughout the final product, avoiding the distribution issues that would occur with direct addition.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If water content is increased to improve solubility, then gingerdiol can be dissolved, but the composition becomes less stable and more prone to microbial growth

Engineering Contradiction:
Improvecomposition stabilityVSAvoidwater content
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent changes the parameter of the solvent from water to polyol (such as glycerol, propylene glycol, or sorbitol). This parameter change allows gingerdiol to be dissolved while maintaining low water content (less than 5 wt%), thereby preserving composition stability and preventing microbial growth while achieving adequate solubility.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If gingerdiol concentration is increased to enhance therapeutic effect, then antibacterial and anti-inflammatory properties improve, but distribution uniformity decreases

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoiddistribution uniformity
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent uses polyol as an intermediary medium that can dissolve high concentrations of gingerdiol while maintaining uniform distribution. This mediator enables the formulation to achieve both high therapeutic efficacy through increased gingerdiol concentration and uniform distribution throughout the oral care composition.

Inventive Principle:
Principle #24Intermediary (Mediator)
