Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional oral compositions for removing tooth stains often damage teeth and gums, particularly due to the use of acidic conditions and peroxide, which also dissolves calcium phosphate, leading to enamel dissolution.

Innovation Solution

An oral composition containing 3.5 to 30% peroxide and 5 to 20% phosphate polymers, preferably ultraphosphate, at a predetermined concentration, effective in neutral pH conditions, combined with an infrared heating substance like charcoal, and optionally polyethylene glycol, to enhance whitening and prevent enamel dissolution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If peroxide is used to remove tooth stain, then whitening effect is improved, but damage to teeth and gums increases

Engineering Contradiction:

Improvewhitening effectVSAvoiddamage to teeth and gums

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent uses phosphate polymers (specifically ultraphosphate) as an intermediary substance that works synergistically with peroxide to enhance stain removal while reducing peroxide's harmful effects. The phosphate polymer forms a complex with the stain that can be removed more easily, allowing lower peroxide concentrations to achieve the same whitening effect, thereby reducing damage to teeth and gums.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the concentration parameters of both peroxide (0.1-10%) and phosphate polymer (1-20%) to optimize the balance between whitening effectiveness and tissue safety. By controlling these parameters within specific ranges, the composition achieves sufficient stain removal while minimizing the damaging effects of peroxide on dental tissues.

Inventive Principle:

2Productivity

If acidic conditions are used to remove tooth stain, then stain removal capability is improved, but enamel dissolution increases

Engineering Contradiction:

Improvestain removal capabilityVSAvoidenamel dissolution

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the typically harmful acidic environment into a beneficial one by using phosphate polymers that work effectively at neutral pH. The phosphate polymer structure allows it to chelate with stain molecules and facilitate their removal without requiring acidic conditions, thereby eliminating enamel dissolution while maintaining effective stain removal capability.

Inventive Principle:

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

Solution Approach 2:

The patent fundamentally changes the pH parameter from acidic (conventional) to neutral (invention), eliminating enamel dissolution. The phosphate polymer is specifically selected for its ability to function at neutral pH, where it can still effectively bind to and remove stains without the harmful side effects of acid exposure.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If peroxide concentration is increased to enhance whitening, then whitening effect is improved, but dissolution of calcium phosphate increases

Engineering Contradiction:

Improvewhitening effectVSAvoiddissolution of calcium phosphate

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The phosphate polymer acts as an intermediary that binds to calcium phosphate and protects it from peroxide attack. This protective complex allows higher peroxide concentrations to be used for enhanced whitening while the phosphate polymer shields the tooth minerals from dissolution, maintaining structural integrity while achieving better whitening results.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite system where phosphate polymer and peroxide work together in a synergistic relationship. The phosphate polymer component protects the tooth structure while the peroxide component provides whitening action, achieving a balance where enhanced whitening effect is obtained without proportional increase in calcium phosphate dissolution.
