Solution Overview
Problem
Existing teeth whitening solutions, whether at home or in-office, are either time-consuming or inconvenient and costly, as they often require prolonged application of hydrogen peroxide or expensive commercial light systems.
Innovation Solution
A portable teeth whitening apparatus featuring a detachable mouthpiece and a light source that emits light according to a variable intensity lighting scheme, allowing for efficient teeth whitening in a compact, user-friendly format, with safety sensors to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If commercial light systems are used for teeth whitening, then treatment time is reduced to under an hour, but the device size and cost increase making them suitable only for dental professionals
Solution Approach 1:
The invention divides the commercial light system into two separate components: a reusable main unit containing the light source and control electronics, and a disposable mouthpiece. This segmentation allows the complex light-emitting components to be contained in a compact main unit while the mouthpiece can be easily replaced, reducing overall device complexity and cost for the consumer while maintaining effective treatment capability
Solution Approach 2:
The mouthpiece is designed as a disposable component that is discarded after a single use or limited number of uses. This eliminates the need for expensive, precision-manufactured reusable mouthpieces while ensuring optimal performance and hygiene for each treatment session, making the overall system more affordable for consumer use
2Device complexity
If home whitening with peroxides alone is used, then device complexity is reduced for home use, but treatment time increases to several hours per day over weeks
Solution Approach 1:
The invention merges the advantages of both approaches by combining a simplified home-use device structure with the time-efficient light-activated whitening technology. The main unit provides controlled light emission similar to professional systems, while the disposable mouthpiece maintains ease of home use, achieving both simplicity and effectiveness
Solution Approach 2:
The system controls light emission parameters (intensity, duration, waveform patterns including square, sine, sawtooth, or triangle waves with 1-3 second wavelengths) to optimize the whitening process. This parameter control enables effective treatment in under an hour while maintaining a simple home-use device structure
3Productivity
If high intensity light is used for effective whitening, then treatment effectiveness improves, but user safety risks increase
Solution Approach 1:
The system employs periodic light emission with various waveform patterns (square, sine, sawtooth, triangle waves) having wavelengths of 1-3 seconds. This periodic action delivers high intensity light in controlled pulses that are effective for whitening while allowing intervals that reduce thermal buildup and minimize potential harm to oral tissues
Solution Approach 2:
The system incorporates safety sensors that detect the presence of the mouthpiece and monitor treatment conditions. This feedback mechanism ensures light is only emitted when the mouthpiece is properly in place, preventing accidental exposure and ensuring user safety while maintaining treatment effectiveness
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 portable apparatus provides effective teeth whitening with customizable lighting schemes, reducing treatment time and cost, while ensuring user safety and comfort, achieving better results than traditional home whitening methods without the need for dental professional visits.
Implementation Method 1
a light source within the housing for emitting light to be applied to teeth of a user... allow at least a portion of light emitted from the light source to pass through the mouthpiece to the teeth of the user
Implementation Method 2
A reflective ring may be included in the mouthpiece to contain light and direct it to the teeth
Data Source
AI summary
A portable teeth whitening device comprising a housing having a light source and a power source therein. The light source is designed to emit light through a removable mouthpiece to the teeth of a user during a whitening session. A microcontroller controls the output of the light source according to one or more lighting schemes to optimize whitening treatments.
