Nail-Cleaning Hand Device for Hyponychium Pathogen Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inadequate hand cleaning techniques and frequency lead to the retention and transmission of infectious agents, particularly in high-risk environments like hospitals, despite the availability of cleaning agents and tools, due to the persistence of pathogens on hands, especially around nails and hyponychium skin.
Innovation Solution
A device composed of compressible materials that expand to facilitate the application of cleaning agents to the underside of nails and hyponychium skin, using atmospheric pressure and rotational forces to ensure thorough cleaning and reduce cross-contamination between digits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hand cleaning methods are used, then general hand surface cleaning is achieved, but inadequate cleaning of nail and hyponychium areas occurs, leading to retention of infectious agents
Solution Approach 1:
The device divides the hand cleaning function into multiple independent cleaning elements arranged in arrays. These elements are positioned to simultaneously contact different areas of the hand including fingers, palms, and specifically the nail and hyponychium regions, allowing each segment to address specific hard-to-reach areas that traditional single-piece cleaners cannot access
Solution Approach 2:
The cleaning device transitions from traditional two-dimensional surface cleaning to three-dimensional cleaning by incorporating elements that can penetrate and clean within the crevices of nail beds and hyponychium areas. The arrays of cleaning elements are positioned at multiple depths and angles to access these previously unreachable three-dimensional spaces
2Reliability
If cleaning frequency is increased, then infectious agent reduction is improved, but time consumption and disruption to daily activities increase
Solution Approach 1:
The device enables self-service hand cleaning by allowing individuals to effectively clean their own hands, including difficult-to-reach areas, without requiring assistance from others. This autonomy makes frequent cleaning more practical and less disruptive to daily routines
Solution Approach 2:
The cleaning device is designed to maintain continuous contact with the hand surfaces during the cleaning process, ensuring that all areas including nails and hyponychium regions are consistently cleaned throughout the brief cleaning interval, maximizing pathogen removal efficiency in minimal time
3Reliability
If thorough cleaning technique is applied, then infectious agent retention is reduced, but cleaning complexity and skill requirements increase
Solution Approach 1:
The device performs the complex task of cleaning hard-to-reach areas automatically through its designed structure, eliminating the need for users to master complex manual techniques for cleaning under nails and in hyponychium regions
Solution Approach 2:
The device combines multiple cleaning functions into a single integrated unit that simultaneously cleans the palm, fingers, nails, and hyponychium areas, reducing the complexity of performing multiple separate cleaning actions with different tools or techniques
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reduces the level of infectious agents on hands by ensuring thorough cleaning of hard-to-reach areas, thereby preventing the transmission of communicable diseases.
Implementation Method 1
the body may be configured to expand upon being exposed to an increase of atmospheric pressure above a threshold atmospheric pressure
Implementation Method 2
Various cleaning agents (such as, among others, antibacterial hand washes, surfactants (soaps), and sanitizers, and the like), in addition to various tools

AI summary
A device for reducing a level of infectious agents present on one or more hands of a user. This device may reduce the level of infectious agents present on one or more fingers and/or thumbs of a user, specifically reducing a level of infectious agents present on the distal aspect of the digit; including, but not limited to an underside of a nail plate, and an area of hyponychium skin between a free margin of the nail plate and an onychodermal band of a digit, such as for example, a finger, thumb, or toe.
