Solution Overview

Problem

Current fluorine-based dental treatments, such as varnishes, have limitations including short duration of action, discomfort, and difficulty in maintaining a stable fluorine concentration in the oral cavity, and are not effectively adhered to teeth surfaces for extended periods.

Innovation Solution

A tape-type fluorine preparation using a biodegradable hydrophilic polymer, like polyvinyl alcohol or methyl cellulose, with a pressure-sensitive adhesive, which is designed to slowly release fluorine and self-degrade over time, ensuring prolonged fluorine concentration and improved adhesion to teeth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If fluorine varnish is applied to teeth, then fluorine concentration is increased and adhesion to teeth is improved, but the varnish is easily removed by saliva or food and cannot maintain suitable fluorine concentration for long time

Engineering Contradiction:

Improveduration of fluorine releaseVSAvoidadhesion stability

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent changes the polymer composition parameters by using biodegradable polymers with specific molecular weights and degradation rates, adjusting the fluorine ion release kinetics to maintain stable concentration over extended periods while ensuring the preparation remains attached to teeth

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite fluorine preparation consisting of fluorine ions embedded in a biodegradable polymer matrix, combining the benefits of controlled fluorine release with sustained adhesion properties and eventual self-degradation

Inventive Principle:

Principle #40Composite materials

2Quantity of substance

If fluorine gel is used for fluorine application, then fluorine ions are delivered to teeth, but the gel is hydrophilic, has short contact time, and presents swallowing risk

Engineering Contradiction:

Improvefluorine ion deliveryVSAvoidcontact time

Core Design Contradiction:

Quantity of substanceVSDuration of action of moving object

Solution Approach 1:

The patent transforms the physical state parameters from gel to a more stable preparation form with controlled viscosity and adhesion properties, extending contact time from minutes to hours while maintaining fluorine ion delivery capability and eliminating swallowing risks

Inventive Principle:

Principle #35Parameter changes

3Strength

If fluorine varnish with resin as main component is used, then fluorine binds to natural resin with high adhesion to teeth, but causes temporary discoloration, unpleasant flavor, and sticky texture

Engineering Contradiction:

Improveadhesion strengthVSAvoiddiscoloration and unpleasant flavor

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by replacing conventional resin with biodegradable polymers that have similar adhesion properties but do not cause discoloration or unpleasant flavor, while maintaining the ability to bind fluorine ions and adhere to tooth surfaces

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses biodegradable polymers that temporarily adhere to teeth to deliver fluorine ions, then naturally degrade and are eliminated by the body, providing a temporary but effective treatment without long-term side effects like discoloration

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
