Solution Overview

Problem

Conventional hand sanitizers are ineffective in thoroughly cleaning and disinfecting the areas under fingernails, leading to potential contamination of food and other products.

Innovation Solution

A nail cleaning pen tool with a brush portion and a hook portion, filled with antibacterial hand sanitizer, which allows for effective cleaning and disinfecting of both the top and underside of fingernails by releasing sanitizer gel through bristles and using a soft hook to remove debris.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional hand sanitizers are used, then hand surface disinfection is achieved, but fingernail area sanitization is insufficient

Engineering Contradiction:

Improvesanitization effectivenessVSAvoidaccess to fingernail areas

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device is segmented into distinct functional components: a brush portion with bristles for reaching under fingernails, a hook portion for removing debris, and a fluid reservoir for sanitizer delivery. This segmentation allows each component to address specific cleaning needs that conventional sanitizers cannot reach.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device introduces intermediary tools (brush bristles and hook) that physically reach into the fingernail area to deliver sanitizer and remove debris. These intermediaries bridge the gap between the user's hand and the difficult-to-reach areas under fingernails, enabling effective sanitization.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If hand washing is avoided, then convenience is improved, but contamination risk increases

Engineering Contradiction:

Improveportability and convenienceVSAvoidgerm and bacteria contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device enables self-service sanitization of fingernail areas that would otherwise require professional attention or thorough hand washing. The integrated brush, hook, and sanitizer reservoir allow users to independently clean and disinfect their own fingernails on-demand.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The device combines multiple functions into a single portable tool: applying sanitizer, mechanical brushing, debris removal with hook, and cuticle care. This multi-functionality replaces the need for multiple separate products and enables comprehensive nail care without water or traditional hand washing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If fingernails are not cleaned, then time is saved, but food and product contamination occurs

Engineering Contradiction:

Improvetime efficiencyVSAvoidcontamination of food and products

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The device enables preliminary cleaning and sanitization of fingernails before handling food or products. By addressing fingernail contamination proactively, users prevent potential contamination issues before they occur, ensuring hygiene compliance without interrupting workflow.

Inventive Principle:

Principle #10Preliminary action
