Tampon Removal String Loop Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tampons with exposed removal strings can be embarrassing and inconvenient, especially during activities like swimming, as they may draw attention and require cutting, which can be impractical and risky without access to scissors, and may lead to difficulties in removal.
Innovation Solution
A tampon design featuring a removal string with one end permanently or releasably attached to the tampon body, forming a shortened single loop that extends less than half the length of the string, allowing for concealed use and easy removal by grasping the loop with a finger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the removal string is made long to facilitate removal, then ease of removal is improved, but visibility and embarrassment are worsened
Solution Approach 1:
The removal string is folded back onto itself and nested within the tampon body, creating a compact configuration that conceals the string's full length while preserving the ability to grasp and pull for removal
Solution Approach 2:
The string transitions from a linear extended form to a three-dimensional loop configuration that fits within the tampon body, changing its spatial arrangement to achieve concealment while maintaining functionality
2Object-affected harmful factors
If the removal string is cut short to prevent exposure, then visibility is improved, but ease of removal is worsened
Solution Approach 1:
The string is nested within the tampon body in a loop configuration, achieving concealment without actual shortening of the string length, thus maintaining removal ease while preventing exposure
3Ease of operation
If the removal string is made accessible for easy removal, then ease of operation is improved, but risk of loss or difficulty in retrieval is worsened
Solution Approach 1:
The loop configuration nests the string ends together within the tampon body, making the string easily graspable as a single unit while preventing the ends from separating or getting lost during removal
Solution Approach 2:
The string is pre-configured into a loop with ends attached to the tampon body, preparing the removal mechanism in advance so that the user can reliably grasp and pull without risk of the string ending up misplaced
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 tampon design effectively conceals the removal string, preventing embarrassing exposure and simplifying removal without the need for cutting, ensuring safe and reliable use during activities like swimming and other situations.
Implementation Method 1
a hydrophobic portion at the distal or string or cord end to block water absorption
Implementation Method 2
a hydrophilic portion for blood absorption

AI summary
An improved tampon has a tampon body and a removal string, having a length (L) between a first end and second end permanently affixed at or along at least one first end of the string to the tampon body and wherein the second end is looped back into the tampon body and attached thereto to form a shortened single loop. The second end can be permanently attached or removably attached to the tampon body and the single loop extends from the tampon body a distance (D) less than half the length (L) of the removal string.
