Oral Cleaning Feedback System for Brushing Coverage Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral cleaning devices fail to effectively track and improve brushing coverage and quality, as they cannot adequately detect and correct inadequacies in brushing techniques, especially in hard-to-reach areas of the mouth.
Innovation Solution
A system that uses sensors to monitor and analyze brushing parameters during a primary cleaning session, providing feedback and guiding users through a secondary cleaning session to ensure optimal coverage and quality, including instructions on regions to brush and duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are used to track toothbrush position and movement, then brushing coverage tracking is improved, but the system cannot detect brushing quality and correct inadequacies
Solution Approach 1:
The system provides real-time feedback to the user through visual, audible, or haptic signals when brushing inadequacies are detected. The processor analyzes sensor data to identify areas requiring additional attention and guides the user to revisit those areas, creating a closed-loop feedback system that continuously monitors and corrects brushing quality.
Solution Approach 2:
The system pre-identifies areas that require additional brushing attention during the initial cleaning session and prepares guided instructions for a secondary cleaning session. By analyzing sensor data in real-time and pre-determining which areas need improvement, the system prepares corrective actions before the user completes the initial brushing routine.
2Duration of action of moving object
If a timed cleaning session is used to guide brushing activity, then brushing duration is improved, but brushing quality and coverage adequacy are not detected
Solution Approach 1:
The system replaces simple mechanical timing mechanisms with sophisticated sensor-based detection and processing systems. Instead of merely tracking elapsed time, the processor analyzes sensor data from accelerometers, gyroscopes, and position sensors to evaluate brushing quality, coverage adequacy, and technique effectiveness, substituting mechanical time-based guidance with intelligent data-driven assessment.
3Ease of operation
If internal sensors in the toothbrush are used to track movement, then device portability is improved, but the ability to accurately identify and track mouth regions deteriorates
Solution Approach 1:
The system merges data from multiple sensor types (accelerometers, gyroscopes, position sensors) within the toothbrush with reference maps of the user's oral cavity. By combining information from these diverse sensing elements and cross-referencing with stored anatomical maps, the system achieves accurate mouth region identification despite using only internal sensors in a portable device.
