Toothbrush Recommendation System Using Questionnaire-Based Bristle Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of technology to assist users in selecting a suitable toothbrush based on their oral condition and brushing habits, leading to inadequate oral hygiene.
Innovation Solution
A toothbrush recommendation apparatus that includes user input and output units, and an operation control unit to determine the number of bristle lines, bristle strength, and shape through questionnaires, recommending a suitable toothbrush type and providing guidance on replacement timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users arbitrarily select toothbrushes based on experience or price, then selection process is simple and quick, but toothbrush suitability for oral condition deteriorates
Solution Approach 1:
The system performs preliminary assessment through questionnaires about oral conditions, brushing habits, and preferences before recommending a toothbrush. This advance evaluation ensures the recommended toothbrush is suitable for the user's specific needs, resolving the contradiction by making the selection process both simple (automatic recommendation) and reliable (based on comprehensive assessment).
Solution Approach 2:
The system enables users to self-assess their own oral conditions and preferences through questionnaires, then automatically generates personalized toothbrush recommendations. This self-service approach maintains ease of operation while improving reliability by base recommendations on user-specific data rather than arbitrary selection.
2Reliability
If comprehensive questionnaires are used to determine toothbrush type, then toothbrush suitability improves, but system complexity increases
Solution Approach 1:
The recommendation system is segmented into distinct functional modules: questionnaire management unit, analysis unit, and recommendation generation unit. Each module handles a specific aspect of the recommendation process, making the overall complex system manageable and maintainable while ensuring comprehensive assessment for accurate recommendations.
Solution Approach 2:
The system uses a universal questionnaire framework that can assess multiple aspects of oral conditions, brushing habits, and preferences through a single integrated system. This multi-functional approach covers various determination criteria (bristle hardness, brush head size, shape) without requiring separate systems, balancing comprehensiveness with system simplicity.
3Measurement precision
If multiple determination criteria are evaluated, then recommendation precision improves, but information processing time increases
Solution Approach 1:
The system implements a tiered questionnaire approach where essential oral condition criteria are assessed first to provide a basic recommendation, and additional detailed criteria can be optionally assessed for more precise recommendations. This allows users to complete the essential assessment quickly while having the option to provide more information for enhanced precision if needed.
Solution Approach 2:
The system replaces manual evaluation of multiple criteria with automated analysis algorithms that process questionnaire responses efficiently. The analysis unit automatically evaluates multiple determination criteria (bristle hardness, brush head size, shape compatibility) and generates recommendations without manual intervention, reducing processing time while maintaining assessment precision.
Data Source
AI summary
The present invention relates to a toothbrush type recommendation apparatus. The toothbrush type recommendation apparatus comprises: a user input unit; an output unit; and an operation control unit connected to the user input unit and the output unit. The operation control unit outputs a questionnaire to the output unit, the questionnaire including questions for determining the number of lines of bristles, questions for determining bristle strength, and questions for determining bristle shape, receives answers to the questionnaire as input from the user input unit and calculates a score for determining the number of lines of bristles and a score for determining bristle strength, determines the number of lines of bristles and the bristle strength corresponding to the respective calculated scores, determines a final bristle shape as a toothbrush type for the determined bristle strength on the basis of the answers to the questionnaire questions for determining bristle shape, and outputs the selected toothbrush type to the output unit.
