Solution Overview

Problem

Users often forget to exchange personal care implements like toothbrushes and shavers, leading to reduced effectiveness and potential health issues due to worn-out devices, and existing guidance systems are complex, require electronic components, or fail to provide hygienic storage solutions.

Innovation Solution

A personal care guidance system featuring a magnetic personal care guide that is magnetically attachable and detachable from a personal care implement made from magnetic and/or ferromagnetic material, providing a guidance tool that reminds users to exchange the implement and offers hygienic storage by allowing water and saliva to drain, reducing bacterial growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users store toothbrushes in traditional open beakers, then the implements are easily accessible, but water accumulates at the bottom causing slow drying and bacterial growth

Engineering Contradiction:
ImproveAccessibility of toothbrushVSAvoidBacterial growth
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs a porous ceramic material for the toothbrush holder that allows water to be absorbed and evaporated through the porous structure. The porous nature enables rapid drying by drawing moisture away from the toothbrush bristles and preventing water accumulation, thereby eliminating the bacterial growth environment while maintaining accessibility.

Inventive Principle:
Principle #31Porous materials

2Loss of information

If existing guidance systems use electronic components and smartphone apps, then tracking and reminder functions are provided, but the device complexity and cost increase

Engineering Contradiction:
ImproveTracking of usage timeVSAvoidElectronic components
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent implements a self-service mechanism where the ceramic holder passively tracks toothbrush usage through water absorption patterns. The porous material naturally absorbs moisture from used toothbrushes and releases it during drying periods, creating a passive tracking system that indicates usage frequency and time without requiring electronic sensors, batteries, or smartphone connectivity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces electronic tracking systems with a passive physical mechanism based on capillary action and evaporation. The porous ceramic structure automatically records usage information through moisture absorption and drying cycles, substituting complex electronic monitoring with simple physics-based observation of the material's hygroscopic properties.

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

3Loss of substance

If personal care implements are used beyond recommended time, then users save money by not replacing them frequently, but the effectiveness decreases and health risks increase

Engineering Contradiction:
ImproveReplacement frequencyVSAvoidEffectiveness of personal care
Core Design Contradiction:
Loss of substanceVSReliability

Solution Approach 1:

The patent provides visual feedback through the ceramic holder's changing appearance as it absorbs and releases moisture over time. The holder displays different moisture levels and usage patterns through visible changes in the porous material, giving users immediate feedback on when their toothbrush has been in use long enough to require replacement, thereby maintaining effectiveness without unnecessary replacement.

Inventive Principle:
Principle #23Feedback
