Finger Sanitizing Container With Segmented Bristles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sanitizing fingers, especially around fingernails, are not effective in reaching crevice regions and do not provide deep penetration, leading to incomplete germicidal action and potential bacterial growth.
Innovation Solution
A portable system with a container holding sanitizing liquid and bristles of varying heights and widths, allowing for scrubbing action to effectively clean and sanitize fingers, including areas around fingernails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If liquid sanitizer is applied by simple rubbing on the hands, then the sanitizing process can be completed quickly, but the liquid does not penetrate deeply into crevice regions of the fingers and fingernails
Solution Approach 1:
The device segments the sanitizing function by introducing bristles that physically divide and reach into crevice regions, allowing the liquid sanitizer to be delivered directly to hard-to-reach areas rather than relying on surface-level rubbing alone
Solution Approach 2:
The bristles act as an intermediary element between the liquid sanitizer and the crevice regions, facilitating deep penetration of the sanitizing liquid into areas that cannot be reached by direct application or rubbing alone
2Ease of operation
If liquid sanitizer is applied by simple rubbing on the hands, then the process is convenient and quick, but it does not provide thorough cleaning of crevice regions where bacteria can grow
Solution Approach 1:
The device enables self-service sanitizing by allowing users to simply insert their fingers into the container and move them around, with the bristles automatically providing the scrubbing action needed to clean crevice regions without requiring manual scrubbing effort
Solution Approach 2:
The bristle array segments the cleaning function across multiple contact points, ensuring that different areas of the finger and nail crevices are simultaneously addressed during a single insertion, maintaining both convenience and thoroughness
3Reliability
If disposable sanitizing systems are used, then pathogen isolation is improved, but the environmental impact increases due to waste
Solution Approach 1:
The device offers a disposable embodiment that is inexpensive and single-use, ensuring that pathogens are isolated in a discarded container rather than potentially contaminating reusable surfaces, while the low cost makes the environmental trade-off acceptable
Solution Approach 2:
The device can function in both disposable and reusable modes, providing universal applicability that allows users to choose the appropriate mode based on their specific needs for pathogen isolation versus environmental considerations
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 system provides a quick and thorough cleaning and sanitizing method, reducing the risk of infection and germ spread by ensuring deep penetration into crevice regions.
Implementation Method 1
A plurality of bristles extend from one or both interior surfaces of the container for contact with a portion of a finger inserted in the container

AI summary
Systems and methods for cleaning or sanitizing a finger. A container has an interior sized to receive a finger, the container having a bottom portion and a wall portion extending from the bottom portion to an opening along an edge of the wall portion through which the finger may be received. The wall portion and bottom portion each have an interior surface within the container. A plurality of bristles extend from an interior surface of the container for contact with a portion of the finger when liquid is in the container.
