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 and storage methods.

Innovation Solution

A kit comprising a personal care implement with a magnetic handle made from ferromagnetic material and a magnetic holder with a built-in timer, allowing for magnetic attachment and detachment, which activates the timer and provides visual, acoustic, and haptic feedback for brushing guidance while enabling quick drying and hygienic storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a manual toothbrush is stored in a classical toothbrush beaker, then the brush can be stored, but the fluids accumulate at the bottom and the brush dries slowly, leading to bacterial growth

Engineering Contradiction:
ImprovehygieneVSAvoiddrying time
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

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 attaches the brush horizontally or at an angle to a magnetic surface, allowing water to drain off completely and the brush to dry from all surfaces exposed to air

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention replaces the passive mechanical storage system (beaker relying on gravity alone) with a magnetic attachment system that provides active holding force, enabling the brush to be positioned optimally for drying while maintaining secure storage

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If electronic tracking systems are incorporated into manual toothbrushes, then brushing time can be tracked, but the device complexity and cost increase significantly

Engineering Contradiction:
Improvebrushing time trackingVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The invention introduces a magnetic holder as an intermediary device that contains the electronic tracking components (timer, sensor, indicator) separate from the manual toothbrush itself. The holder detects when the brush is removed via magnetic field changes and activates the timer, providing tracking functionality without modifying the simplicity of the brush

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The magnetic holder automatically detects brush removal through magnetic field sensing and self-activates the timer without requiring user intervention, eliminating the need for buttons, switches, or complex user interactions to start tracking

Inventive Principle:
Principle #25Self-service

3Loss of information

If a magnetic holder with timer is used, then brushing time can be tracked and feedback provided, but the holder becomes more complex

Engineering Contradiction:
Improvebrushing guidanceVSAvoidholder complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The invention concentrates all electronic and control components (magnet, timer, sensor, indicator) into a single localized magnetic holder unit, keeping the toothbrush itself simple and separate. This localizes the complexity to one component rather than distributing it throughout the system

Inventive Principle:
Principle #3Local quality
