Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral care systems fail to adapt brushing routines to individual users' specific goals and oral characteristics, such as sensitivity areas and different brushing sessions, leading to suboptimal oral hygiene.
Innovation Solution
An oral care system that includes a toothbrush with sensors and a programmable processor to collect data on physical properties and user inputs, determining a suggested brushing routine and evaluation based on the collected data, adjusting for unique user needs and habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standardized oral care routine is imposed on all users, then the accepted standard for oral hygiene is maintained, but individual user needs and oral characteristics are not addressed
Solution Approach 1:
The system dynamically adjusts brushing routines based on real-time sensor data collected during brushing sessions. The programmable processor modifies brushing parameters such as duration, intensity, and frequency according to detected oral characteristics and user responses, transforming a static standardized routine into a dynamic adaptive one that evolves with individual user needs.
Solution Approach 2:
The system changes multiple parameters of the brushing routine including duration, pressure, frequency, and sequence of brushing areas based on sensor feedback. The programmable processor adjusts these parameters to match individual user oral characteristics and goals, such as extending brushing time in sensitive areas or modifying intensity levels.
2Measurement precision
If sensors are added to evaluate brushing effectiveness, then brushing evaluation accuracy is improved, but device complexity increases
Solution Approach 1:
The sensor system is designed with multi-functionality, where a single sensor array serves multiple purposes: detecting oral characteristics, monitoring brushing technique, measuring pressure application, and evaluating overall brushing effectiveness. This universal sensor approach reduces the need for multiple separate sensing systems while maintaining comprehensive evaluation capabilities.
Solution Approach 2:
The system uses the toothbrush itself to collect and process data about its own performance during brushing sessions. The programmable processor within the toothbrush automatically analyzes sensor data and generates evaluations without requiring external equipment or manual measurement, enabling the device to self-assess and provide feedback.
3Reliability
If brushing routine is customized for each user, then individual oral care effectiveness is improved, but time required to determine and implement routine increases
Solution Approach 1:
The system performs preliminary characterization of the user's oral characteristics during initial brushing sessions using sensor data. The programmable processor analyzes patterns and builds a profile of the user's oral anatomy and sensitivity areas in advance, which then guides the customization of the brushing routine for subsequent sessions without requiring continuous real-time analysis.
Solution Approach 2:
The system implements feedback loops where sensor data from each brushing session is analyzed and used to refine the personalized routine for the next session. The programmable processor continuously learns from user responses and brushing outcomes, automatically adjusting the routine parameters to optimize effectiveness while reducing the time needed for manual customization.

AI summary
An oral care system including a toothbrush having a sensor that generates brushing data during a brushing session and a programmable processor. The programmable processor may be configured to receive the brushing data from the sensor, receive oral characteristic data indicative of an oral characteristic of the user, and determine at least one of a suggested brushing routine and a brushing evaluation for a brushing session based at least in part on the oral characteristic data and the brushing data. The oral characteristic may be present in or adjacent to a first portion of the dentiture. The brushing evaluation or brushing routine may be based on or includes at least one of: an altered target brushing time for the first portion of the dentiture; and a modified brushing motion expectation for the first portion of the dentiture.
