Disposable Grease-Resistant Finger Covers with Adhesive Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eating messy foods like chicken wings, ribs, sushi, and shellfish often results in grease and sauce being transferred to the hands, requiring multiple napkins for cleanup and not effectively preventing the mess.
Innovation Solution
Disposable protective finger covers made from grease-resistant materials, specifically designed to cover the thumb, index, and middle fingers, using an adhesive layer and tab configuration for secure fitting, preventing grease and sauce from penetrating to the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If disposable protective finger covers are used, then grease and sauce transfer to hands is prevented, but device complexity increases
Solution Approach 1:
The protective cover is divided into multiple functional segments: a central body portion covering the finger, tabs for securing, adhesive layers for attachment, and release sheets for application. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity
Solution Approach 2:
An adhesive layer is introduced as an intermediary between the protective cover and the finger to ensure secure attachment. The release sheet serves as another intermediary that facilitates easy application by allowing controlled adhesion activation
2Reliability
If adhesive layers and release sheets are added, then secure fitting is achieved, but manufacturing complexity increases
Solution Approach 1:
The adhesive layer and release sheet are combined into a single integrated component that is pre-assembled with the protective cover. This merging reduces the number of separate manufacturing steps and simplifies the production process while ensuring reliable attachment
3Object-affected harmful factors
If the cover is designed to substantially enshroud the finger, then protection effectiveness is improved, but ease of operation decreases
Solution Approach 1:
The protective cover incorporates flexible tabs that can be dynamically adjusted and wrapped around the finger to achieve the desired coverage level. This dynamic design allows users to customize the fit and protection level based on their specific needs and dexterity
Solution Approach 2:
The cover is segmented into a central body and multiple tabs, allowing incremental application and adjustment. Users can apply the central body first and then add tabs as needed, making the application process more manageable and less intimidating
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
Effectively reduces the transfer of grease and sauce to the hands during meals, minimizing cleanup needs and providing a comfortable, flexible solution for handling greasy foods.
Implementation Method 1
The flexible sheet has an adhesive layer on at least a portion of its rear surface
Implementation Method 2
The front surface of the flexible sheet has a grease resistant surface for repelling grease and sauces from finger foods being handled by the user

AI summary
A disposable protective cover for use on a finger while eating has a grease resistant flexible sheet that can be secured to a finger for repelling grease and sauces from foods being handled. The central body portion of the cover is approximately the same width and length as the finger. An upper tab extends from the upper end of the central body, and a lower tab extends from the lower end. A left tab and a right tab extend from the sides. The rear side of the sheet has an adhesive and a release sheet covering the adhesive. The user removes the release sheet to expose an adhesive on the rear surface, places the finger on the central body portion so that the lower tab extends onto the user's palm. The user then folds the upper tab over the fingertip and wraps the left and right tabs around the finger.
