Tampon Applicator Grip Jaw Finger Hook Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tampon applicators with curved stoppers are prone to finger slippage, leading to improper insertion angles and potential misplacement of the absorber within the vagina.
Innovation Solution
A tampon applicator design featuring a grip cylinder unit with a grip jaw unit that includes finger hook units, allowing for secure gripping and controlled insertion of the outer cylinder, ensuring the absorber is placed at the correct position inside the vagina.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a curved stopper is used to guide insertion depth, then the absorber can be disposed at the appropriate position, but the stopper surface causes finger slippage during insertion
Solution Approach 1:
The grip jaw unit is provided with finger hook units at specific locations on its outer circumferential face, creating localized gripping points with enhanced friction properties. This local quality enhancement allows users to securely grip the applicator without affecting the overall smooth surface needed for proper insertion guidance by the stopper.
Solution Approach 2:
The finger hook units act as an intermediary element between the user's fingers and the grip cylinder unit. These hooks provide the necessary friction and grip points, mediating the interaction between the user and the device while the stopper independently performs its depth-guiding function without being compromised.
2Speed
If the outer cylinder is inserted without proper gripping control, then insertion speed increases, but the insertion angle becomes improper and absorber placement is inaccurate
Solution Approach 1:
The finger hook units are designed to be engaged by the user's fingers before the insertion process begins. This preliminary gripping action establishes proper finger placement and control over the outer cylinder, ensuring that the insertion angle is correctly maintained from the start of the insertion process, thereby preventing misplacement while still allowing for efficient insertion speed.

AI summary
A tampon applicator includes an outer cylinder in which an absorber is housed, and a push-out opening through which the absorber is to be pushed out is provided at one side and a grip cylinder unit is provided at the other side, and an inner cylinder which is inserted into the grip cylinder unit and being moved into the outer cylinder to be thereby able to push out the absorber outward through the push-out opening. The tampon applicator includes a grip jaw unit configured to extend from an outer circumferential face of the grip cylinder unit of the outer cylinder outwardly in a radial direction, wherein a finger hook unit by which a finger of a user is to be hooked is formed at the grip jaw unit.
