Solution Overview

Problem

Conventional toothpastes using peroxides for whitening have toxicity issues and stability problems in packaging, and struggle to effectively clean and whiten transitions between natural and artificial teeth surfaces, including edges and pores.

Innovation Solution

A toothpaste containing micronized bleaching agents like calcium peroxide, combined with proteolytic enzymes, which penetrate deep into pores and cracks for enhanced whitening and oral hygiene, while being stable in packaging and non-toxic to bacteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If peroxides are used as whitening agents in toothpaste, then whitening effect is improved, but stability in packaging deteriorates due to oxygen release when in contact with water

Engineering Contradiction:

Improvewhitening effectVSAvoidstability in packaging

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies micronization to change the physical parameter of peroxide particles, reducing their size to micrometer range. This increases surface area and reactivity, enabling effective whitening at lower concentrations (0.1-5%) while improving stability in packaging due to reduced water contact per unit mass

Inventive Principle:

Principle #35Parameter changes

2Reliability

If peroxides are used for whitening, then bleaching effect is improved, but toxicity increases due to harmful effects on oral tissues

Engineering Contradiction:

Improvebleaching effectVSAvoidtoxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the concentration parameter by using micronized peroxide at lower concentrations (0.1-5%) compared to conventional peroxide formulations. The increased surface area of micronized particles provides sufficient whitening effect at reduced concentrations, thereby lowering toxicity to oral tissues

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite formulation combining micronized peroxide with other toothpaste components (abrasives, humectants, binders) that work synergistically to achieve whitening at lower peroxide concentrations, reducing the harmful effects while maintaining effectiveness

Inventive Principle:

Principle #40Composite materials

3Device complexity

If non-micronized peroxide is used, then formulation simplicity is maintained, but penetration into pores and cracks deteriorates

Engineering Contradiction:

Improveformulation simplicityVSAvoidpenetration into pores and cracks

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent changes the size parameter of peroxide particles by applying micronization, reducing particle diameter to micrometer range. This enables penetration into small pores and cracks on tooth surfaces while maintaining formulation simplicity by using unencapsulated particles that can be directly incorporated into toothpaste

Inventive Principle:

Principle #35Parameter changes

4Productivity

If higher peroxide concentration is used, then whitening effectiveness is improved, but stability and safety deteriorate

Engineering Contradiction:

Improvewhitening effectivenessVSAvoidstability and safety

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent changes the concentration parameter by using micronized peroxide at lower concentrations (0.1-5%). The micronization process increases the surface area to volume ratio, making the peroxide more reactive and effective at lower concentrations, thereby achieving whitening effectiveness while improving stability and safety

Inventive Principle:

Principle #35Parameter changes
