Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pet food products primarily focus on mechanical action for oral health maintenance, failing to effectively modulate oral microbiota to prevent or manage periodontal disease in animals.

Innovation Solution

Feeding companion animals a dry pet food to modulate oral microbiota by increasing bacteria associated with good oral health and decreasing bacteria associated with disease, thereby promoting a healthier oral environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If mechanical action products (tooth brushing, dental chews) are used, then plaque removal is improved, but oral microbiota modulation is insufficient

Engineering Contradiction:

Improveplaque removalVSAvoidoral microbiota modulation

Core Design Contradiction:

Object-generated harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent replaces purely mechanical plaque removal methods with a biological approach using probiotic bacteria. The composition contains specific strains (Lactobacillus, Streptococcus, Actinomyces, Porphyromonas) that actively modulate oral microbiota through biological interactions, shifting the microbial balance toward health-promoting species rather than relying solely on mechanical abrasion.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces probiotic bacteria as intermediary agents between the diet and oral microbiota. These bacteria act as mediators that transfer beneficial microbial signals to the oral ecosystem, influencing bacterial composition and promoting health without direct mechanical contact.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If dry pet food is fed, then oral microbiota is modulated towards healthier profiles, but mechanical cleaning action is reduced

Engineering Contradiction:

Improveoral microbiota modulationVSAvoidplaque accumulation

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the parameter of diet consistency from wet to dry, which fundamentally alters how the food interacts with oral microbiota. Dry food particles provide mechanical stimulation during chewing that promotes salivation and bacterial competition, creating a different oral environment that favors health-promoting bacteria while still allowing plaque accumulation to occur naturally without aggressive mechanical intervention.

Inventive Principle:

Principle #35Parameter changes

3Object-generated harmful factors

If aggressive mechanical cleaning is applied, then plaque removal is improved, but oral microbiota diversity is reduced

Engineering Contradiction:

Improveplaque removalVSAvoidoral microbiota diversity

Core Design Contradiction:

Object-generated harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent converts the naturally occurring plaque accumulation process into a beneficial opportunity for probiotic bacteria to establish themselves. Instead of aggressively removing all plaque, the composition allows controlled plaque formation while introducing beneficial bacteria that compete with pathogens, transforming the harmful plaque environment into a site for beneficial microbial colonization.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
