Finger Mountable Implement With Interior Grip Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lip balm dispensers and candy packaging often result in poor user control, leading to unintended spreading or contamination, as individuals typically hold the packaging with a pinching grip, which can cause accidents and messes, especially with vividly colored or sticky substances.
Innovation Solution
A finger mountable implement with a body having a side wall and top panel, featuring a finger grip portion on the interior surface that securely engages a user's finger, allowing for improved control and reduced mess, with optional features like a cap and annular rings or nodules for enhanced grip and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional pinching grip is used to hold the tubular container, then the device is simple to operate, but control precision deteriorates leading to unintended spreading or contamination
Solution Approach 1:
The interior surface of the tubular container is segmented into distinct functional zones: a finger engagement zone with凸起 structures (bumps, ridges, or grooves) for secure gripping, and a material dispensing zone at the open end for controlled application. This segmentation allows the user's finger to be firmly anchored while the thumb or other fingers control material dispensing, resolving the contradiction between easy holding and precise control.
2Measurement precision
If the finger grip portion engages the finger securely, then control precision improves, but device complexity increases due to additional interior surface features
Solution Approach 1:
Rather than complicating the entire container structure, the invention applies localized quality changes only to the interior surface where finger engagement occurs. The凸起 structures (bumps, ridges, or grooves) are confined to a specific region, leaving the rest of the container simple and manufacturable. This localized approach improves control precision without significantly increasing overall device complexity.

AI summary
A finger mountable implement comprising a body defining an open interior space. The body comprises a side wall having an open bottom end and an open top end, and a top panel proximate to the open top end. An interior surface of the side wall includes a figured finger grip portion configured to releasably engage a finger of a user when the finger is inserted into the interior space so as to removably secure the finger within the body.
