Tooth Whitening Device with Venturi Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tooth whitening devices are bulky and impractical for use in a home environment, requiring specialized personnel and are not safe for frequent user application.
Innovation Solution
A compact tooth whitening device with a gripped dispenser and nozzle that combines solid or semi-solid whitening products with liquid products using a Venturi effect to create a mixed flow for efficient delivery, powered by a portable compressor or pressurized gas, allowing for easy and safe use at home.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a professional tooth whitening device with compressor and powder tank is used, then whitening effectiveness is improved, but device size and portability deteriorate
Solution Approach 1:
The patent combines the whitening product storage, pressurization system, and delivery mechanism into a single integrated spray can assembly. The propellant gas and whitening powder are contained within the same dispenser unit, eliminating the need for separate compressors and powder tanks, thus achieving professional whitening effectiveness in a compact portable format.
Solution Approach 2:
The spray can serves multiple functions: it stores the whitening powder, contains the propellant gas, provides pressurization, and delivers the product through the nozzle. This multi-functional design replaces the need for multiple separate components (compressor, powder tank, delivery hose), resolving the contradiction between effectiveness and portability.
2Reliability
If a professional tooth whitening device is used, then whitening performance is improved, but ease of use and safety for home environment deteriorate
Solution Approach 1:
The spray can is designed for self-service operation by the user themselves. The user simply activates the spray mechanism to apply the whitening product directly to their teeth, eliminating the need for specialized personnel or complex setup procedures. This maintains professional-grade whitening performance while making the device easy and safe for home use.
3Stability of the object's composition
If solid whitening product is used, then product stability is improved, but mixing complexity increases
Solution Approach 1:
The patent uses pressurized gas (pneumatics) to both transport the solid whitening powder through the duct and to mix it with the liquid propellant. The gas flow automatically performs the mixing function as it carries the powder particles through the spray mechanism, eliminating the need for separate mixing mechanisms and reducing overall device complexity while maintaining product stability.
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 a safe, user-friendly, and efficient means for frequent tooth whitening, using a mixture of sodium acid carbonate, pink Himalayan salt, essential oils, and abrasive diamond powder, effectively whitening teeth with a dual hygiene and whitening effect.
Implementation Method 1
the passage of the flow of gas through that intermediate position of said first stretch of duct causes the suction and intake into the duct of said at least part of the whitening product by Venturi effect
Implementation Method 2
the passage of the flow of gas through said intermediate position of said second stretch of duct causes the suction and intake into the duct of said product in liquid form by Venturi effect
