Tampon Insertion Device Depth Indicator Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tampon insertion devices lack indicators to inform users of the correct insertion depth, making it difficult for inexperienced individuals, such as teenage girls, to properly deploy the tampon within the vagina.
Innovation Solution
A tampon insertion device featuring a barrel with a depth indicator member on its outside surface, providing both visual and tactile cues to indicate when the device is fully inserted, allowing for correct deployment of the tampon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tampon insertion devices are used without indicators, then the device structure remains simple, but the user cannot determine the correct insertion depth
Solution Approach 1:
A depth indicator member is introduced as an intermediary element between the user and the insertion device. This indicator member provides visual and tactile cues about insertion depth without fundamentally altering the core insertion mechanism, thereby achieving precise depth measurement while maintaining relative structural simplicity.
Solution Approach 2:
The depth indicator member utilizes color changes or visual indicators to communicate insertion depth to the user. By incorporating colored zones, patterns, or transparent/opaque sections on the indicator member, the system provides intuitive visual feedback about whether the correct insertion depth has been achieved, resolving the measurement precision issue.
2Ease of operation
If no depth indicator is provided, then the device is easier to manufacture, but inexperienced users cannot know when proper insertion is achieved
Solution Approach 1:
The depth indicator member serves as a mediator that guides user operation without requiring complex manufacturing processes. It provides tactile and visual cues that are straightforward to implement and manufacture, thereby improving ease of operation while maintaining manufacturing simplicity.
Solution Approach 2:
The depth indicator member can be segmented into distinct zones or sections that correspond to different insertion depths. This segmentation provides clear, discrete guidance points for users (such as visible markers at specific depths) while keeping the manufacturing process relatively simple through modular design.
3Difficulty of detecting and measuring
If the barrel has no external indicators, then the surface is smoother and simpler, but the user lacks tactile feedback for correct insertion
Solution Approach 1:
The depth indicator member acts as an intermediary that adds tactile feedback features to the barrel surface. These features (such as ridges, grooves, or textured zones) provide detectable tactile cues at specific depths without fundamentally altering the smooth cylindrical shape of the main barrel, thereby improving detection capability while maintaining overall shape simplicity.
Solution Approach 2:
The barrel surface maintains its smooth, simple overall shape, but the depth indicator member introduces localized tactile features at specific positions. This local quality modification provides necessary tactile feedback for depth detection while keeping the majority of the barrel surface smooth and simple, resolving the contradiction between surface simplicity and detection capability.

AI summary
A tampon insertion device for inserting a tampon includes a structure for indicating the insertion device is sufficiently inserted into a woman's vagina before deploying the tampon. The tampon insertion device includes a barrel having opposed insertion and proximal end portions and a side wall that defines an interior area therebetween. A tampon is initially positioned in the interior area. A depth indicator having indicia is situated on the side wall of the barrel that is indicative that the barrel is fully inserted, the indicia including one of a recess, a groove, or imprinted matter extending radially about the barrel. The insertion device includes a plunger slidable from a starter configuration extending away from the proximal end portion of the barrel to a deployed configuration positioned downstream inside the interior area. Pressure applied to the plunger causes the plunger to urge the tampon downstream within the interior area.
