Solution Overview

Problem

Conventional oral care compositions rely on bactericidal agents to combat bacteria, but fail to effectively balance the oral microbiome towards promoting good oral health by reducing anaerobic bacteria associated with gum disease and increasing aerobic bacteria.

Innovation Solution

A composition comprising zinc ions and specific enzymes such as amylglucosidase, glucose oxidase, lactoperoxidase, and optionally lysozyme, lactoferrin, and colostrum, which balances the bacterial flora by decreasing anaerobic bacteria and promoting aerobic bacteria, along with surfactants, structurants, and abrasive materials in a dentifrice form.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If bactericidal agents are used to combat bacteria, then bacterial reduction is achieved, but the oral microbiome balance is not effectively improved

Engineering Contradiction:
Improvebacterial reductionVSAvoidoral microbiome balance
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

Instead of using bactericidal agents to kill bacteria, the patent inverts the approach by using enzymes to selectively reduce anaerobic bacteria while promoting aerobic bacteria, thereby achieving microbiome balance through selective modulation rather than broad-spectrum destruction

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent applies different functional properties to different bacterial types: enzymes with specific activity against anaerobic bacteria are used, while conditions favorable for aerobic bacteria are created. This local differentiation in treatment quality enables selective bacterial modulation without affecting all bacteria uniformly

Inventive Principle:
Principle #3Local quality

2Object-generated harmful factors

If conventional anti-bacterials are used, then bacteria are destroyed, but aerobic bacteria associated with good oral health are not increased

Engineering Contradiction:
Improveanaerobic bacteria reductionVSAvoidaerobic bacteria abundance
Core Design Contradiction:
Object-generated harmful factorsVSQuantity of substance

Solution Approach 1:

The patent introduces enzymes as intermediary substances that mediate between the oral environment and bacterial populations. These enzymes selectively target anaerobic bacteria while creating conditions that favor aerobic bacteria, acting as a bridge to achieve the desired microbiome shift without directly adding aerobic bacteria

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes key parameters of the oral environment through enzyme action, including oxygen availability, pH, and substrate composition. These parameter changes create conditions that naturally favor the growth of aerobic bacteria while suppressing anaerobic bacteria, achieving the desired bacterial population shift

Inventive Principle:
Principle #35Parameter changes
