Smart Toothbrush Audio Feedback for Brushing Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many individuals do not brush their teeth for the recommended duration, and existing toothbrushes lack features to make the experience more engaging and fun, leading to suboptimal brushing behavior.
Innovation Solution
Incorporating an audio input device and sensors into toothbrushes to detect humming or singing, with onboard processors or connected computing platforms that provide feedback, scoring, and gamification elements to encourage proper brushing techniques and duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional timers are added to toothbrushes, then brushing duration is tracked, but user engagement and fun are not improved
Solution Approach 1:
The system provides real-time auditory feedback by detecting humming sounds during brushing and providing immediate responses through the audio output device. This feedback loop engages users by making them aware of their brushing behavior and providing encouraging responses, transforming a passive timing function into an interactive experience that motivates proper brushing duration
Solution Approach 2:
The audio processing system acts as an intermediary between the user's natural humming behavior and the brushing guidance system. By detecting humming sounds and translating them into engaging audio feedback, the system creates a pleasant interaction that encourages users to maintain proper brushing duration without feeling monitored or restricted
2Difficulty of detecting and measuring
If audio detection capabilities are added to toothbrushes, then humming detection is enabled, but device complexity increases
Solution Approach 1:
The toothbrush utilizes the user's own humming voice as the detection target, eliminating the need for complex external reference systems. The audio input device captures the user's natural humming, and the processing system compares this self-generated sound against predefined frequency ranges for humming detection, simplifying the overall detection architecture while maintaining accuracy
Solution Approach 2:
The system replaces complex mechanical or visual detection mechanisms with acoustic field-based detection. By using the audio input device to capture humming sounds and processing audio frequency data, the system achieves effective brushing behavior detection without requiring complex mechanical sensors, optical systems, or invasive measurement devices

AI summary
This disclosure presents systems and methods to improve user brushing behavior. Exemplary implementations may: effectuate presentation of audio content via an audio output device, the audio content being characterized by an audio profile; obtain output signals from one or more sensors coupled to a user device, the output signals conveying user input information, the user input information defining user input by a user via the user device; determine, based on the user input information, a user profile, the user profile including one or more user values of the one or more audio attribute; compare the user profile with the audio profile to determine, for individual audio attributes, one or more differences; determine one or more scores reflecting the one or more differences; and/or perform other operations.
