Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral care tools, particularly manual toothbrushes, lack effective tracking and guidance systems for ensuring adequate brushing time and hygiene, leading to inefficient plaque removal and potential bacterial growth due to inadequate drying.
Innovation Solution
A magnetic holder with a built-in timer that activates when the toothbrush is detached, providing visual, acoustic, and haptic feedback to guide brushing time and ensuring hygienic storage by using magnetic attachment and detachment to manage water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual toothbrush is stored in a classical toothbrush beaker, then the toothbrush can be stored, but water accumulates at the bottom and the toothbrush dries slowly leading to bacterial growth
Solution Approach 1:
Instead of storing the toothbrush upright in a beaker where water accumulates at the bottom, the invention inverts the storage approach by using a magnetic holder that allows the toothbrush to be stored horizontally or at an angle, enabling water to drain off completely. The magnetic attachment mechanism holds the brush in a position where gravity causes water to flow off the bristles rather than accumulate, thus inverting the traditional storage geometry to achieve better drainage and faster drying.
Solution Approach 2:
The invention replaces the passive mechanical storage system (toothbrush standing in a beaker) with an active magnetic holding system. The magnetic force provides a controllable holding mechanism that can maintain the toothbrush in an optimal drainage position, substituting gravity-only storage with magnetically-assisted positioning to achieve superior water drainage and drying performance.
2Loss of information
If a timer with microcontroller and wireless module is added to track brushing time, then brushing time can be monitored, but the device becomes complex and expensive
Solution Approach 1:
The invention extracts the timer function from the toothbrush itself and places it in a separate magnetic holder unit. This separation allows the toothbrush to remain simple while the holder contains the electronic timing components. The timer is activated by the magnetic attachment/detachment of the brush, providing brushing time tracking without requiring complex integration within the brush handle, thus reducing overall system complexity while maintaining functionality.
Solution Approach 2:
The magnetic holder serves as an intermediary between the user and the toothbrush, housing the timer and control electronics. Instead of embedding complex circuitry in the brush, the holder acts as a mediator that provides timing functionality through magnetic interaction with the brush, simplifying the brush design while enabling sophisticated tracking capabilities.
3Loss of information
If video images are used to track toothcare activities, then brushing can be monitored, but the system becomes complex and unsuitable for manual toothbrushes
Solution Approach 1:
The invention replaces expensive, complex video tracking systems with a simple, low-cost magnetic timer mechanism. The magnetic holder with timer provides sufficient brushing time tracking information without requiring sophisticated video analysis hardware and software, effectively using a simpler, more affordable solution that is appropriate for manual toothbrushes.
Solution Approach 2:
The invention substitutes optical/video-based tracking with a magnetic-based timing system. Instead of using cameras and image processing to monitor brushing, the system uses magnetic attachment/detachment events to trigger and control a timer, replacing complex optical systems with simpler magnetic and electronic timing mechanisms.
