Interactive Gaming Oral Brush with Motion Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toothbrushing techniques lack effective feedback mechanisms to ensure proper brushing motion and coverage, which can lead to inadequate dental hygiene.
Innovation Solution
An oral care brush equipped with sensors to monitor motion and orientation, coupled with a processor that provides audio and visual feedback through a speaker and light sources, turning brushing into an interactive gaming experience that rewards proper technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors and processors are added to provide feedback mechanisms, then brushing technique monitoring is improved, but device complexity increases
Solution Approach 1:
The patent implements feedback mechanisms through sensors that detect brushing motion and orientation, a processor that analyzes the collected data, and output devices (speaker and light sources) that provide real-time feedback to the user about brushing technique quality
Solution Approach 2:
The patent replaces manual self-assessment of brushing technique with electronic sensing systems, using sensors to detect motion parameters and orientation, and a processor to evaluate whether proper brushing technique is being used
2Ease of operation
If audio and visual feedback systems are implemented, then user engagement is improved, but energy consumption increases
Solution Approach 1:
The feedback systems (speaker and light sources) operate periodically based on detected brushing events rather than continuously, providing feedback only when brushing motions are detected or when technique evaluation is needed
Solution Approach 2:
The system dynamically adjusts feedback intensity and frequency based on brushing behavior, potentially reducing feedback during prolonged proper brushing to conserve energy while maintaining user engagement
3Productivity
If gaming software and real-time feedback are provided, then brushing effectiveness is improved, but device complexity increases
Solution Approach 1:
The processor serves multiple functions: collecting sensor data, analyzing brushing technique, running gaming software, and controlling both audio and visual feedback systems, thereby consolidating complexity into a single multi-functional component
Solution Approach 2:
The system automatically monitors brushing coverage and provides real-time guidance without requiring external monitoring devices or manual intervention, with the gaming software adapting to user performance automatically
Data Source
AI summary
An oral care brush includes a brush head coupled to a handle at an articulation point. A sensor is mounted for monitoring the articulation point to determine whether a brushing motion is proper. One or more tilt sensors can also be mounted in the handle to determine the orientation of the oral care brush relative to gravity. This orientation can also be used to determine proper brushing motion. A processor is mounted within the handle for receiving information from the sensors. A speaker in the handle is coupled to receive information from the processor and provide it to the user. The processor can also provide the user audio game-play scenarios using the speaker. The handle can also include one or more light sources.
