Solution Overview

Problem

Current dental application devices lack control over the amount of solution retained and applied, causing delays and irregularities in dental procedures due to the need to repeatedly dip the applicator tip into a well for bonding agents and other solutions.

Innovation Solution

A dental application device with a containment chamber and a frangible seal that allows controlled dispensing of dental solutions through an applicator tip, enabling precise application and reducing interruptions by allowing the user to reapply solution without removing the applicator from the mouth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the applicator tip is dipped into a well for bonding agent, then the bonding agent is applied to the tooth, but the procedure is delayed and workflow is interrupted due to repeated dipping

Engineering Contradiction:
Improveworkflow efficiencyVSAvoidprocedural delay
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The containment chamber is pre-filled with a predetermined amount of dental solution (bonding agent) before the procedure begins. This preliminary preparation eliminates the need for repeated dipping into the well during the procedure, allowing continuous application without interruption or time loss.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If the applicator tip is dipped into a well for bonding agent, then the bonding agent is applied to the tooth, but the amount of solution retained is not sufficiently controlled

Engineering Contradiction:
Improvesolution controlVSAvoidamount of solution
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The containment chamber is pre-filled with a predetermined amount of dental solution that provides precise control over the quantity delivered. This preliminary measurement and containment of a specific volume ensures consistent, controlled application without waste or excess.

Inventive Principle:
Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device provides continuous and controlled application of dental solutions, reducing procedural delays and improving workflow efficiency by allowing users to vary the pressure for precise solution delivery.

Implementation Method 1

a frangible seal disposed within the material passage that separates the containment chamber from the applicator tip. Removing the frangible seal allows the dental solution to flow from the containment chamber to the applicator tip

Methodology Applied
Scientific EffectFrangible seal:

Implementation Method 2

Deforming at least a portion of the containment chamber displaces a first fluid within the containment chamber and subsequently releasing the containment chamber creates a suction action, allowing a second fluid to be drawn into the containment chamber through the first applicator tip

Methodology Applied
Scientific EffectSuction: Suction

Implementation Method 3

a spring disposed between the button and the second end of the handle. Pressing the button displaces a first fluid within the containment chamber and subsequently releasing the button creates a suction action

Methodology Applied
Scientific EffectSpring force: Spring

AI summary

A dental application device having a handle having a first end, a second end, and a containment chamber disposed within the handle. The device has a dental solution disposed within the containment chamber, a receiver tip coupled to the handle at the first end, a material passage within the receiver tip that forms a conduit between the first end and a receiving end, a frangible seal that separates the containment chamber from the material passage, and a piercing cannula in fluid communication with an applicator tip and having a distal piercing end extending toward the frangible seal. The piercing cannula is moveable between a first position and a second position. When in the first position, the piercing end is spaced apart from the frangible seal, and in the second position, the piercing end punctures the frangible seal and fluidly connects the dental solution with the applicator tip.
