Feminine Napkin Fluid Guide Assembly for Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current feminine hygiene products fail to effectively guide menstrual fluid to a desired location on the napkin, leading to leakage and staining of garments.
Innovation Solution
A feminine napkin assembly featuring a menstrual pad coupled with a fluid guide that directs menstrual fluid to a specific absorbent area, minimizing leakage by using an elongate member attached to the pad to channel fluid towards an optimal absorption zone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If menstrual fluid is not guided to a specific location, then the napkin structure remains simple, but leakage and staining occur due to uncontrolled fluid flow
Solution Approach 1:
A fluid guide member is introduced as an intermediary component between the menstrual fluid source and the absorbent napkin. This mediator channels the fluid along a controlled path, directing it to a specific target area on the napkin, thereby preventing uncontrolled leakage while maintaining a relatively simple overall structure.
Solution Approach 2:
The napkin system is segmented into distinct functional zones: a fluid guide member that directs flow, a target area with enhanced absorbent capacity where fluid is directed, and surrounding areas. This segmentation allows controlled fluid management by creating specific pathways and zones rather than relying on a uniform structure.
2Productivity
If menstrual fluid is directed to a specific absorption zone, then absorption efficiency is maximized, but the napkin requires additional fluid guide components
Solution Approach 1:
The fluid guide member is merged with the napkin structure through attachment mechanisms, integrating the guiding function into the existing absorbent system. This combination allows the fluid direction and absorption functions to work together as a unified system, maximizing absorption efficiency without requiring completely separate components.
3Object-affected harmful factors
If fluid is channeled to a target area, then leakage is minimized, but the napkin assembly becomes more complex
Solution Approach 1:
The napkin employs local quality enhancement at the target area where the fluid guide directs menstrual flow. This target area features increased absorbent capacity or specialized absorbent materials concentrated at the specific location, allowing effective fluid containment and absorption precisely where needed, thereby minimizing leakage without requiring the entire napkin to be overly complex.

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 fluid guide assembly effectively channels menstrual fluid to a targeted absorption area, reducing spillage and enhancing the overall absorption efficiency of the napkin.

Data Source
AI summary
A feminine napkin assembly including a menstrual pad coupled with a fluid guide that directs the flow of menstrual fluid to a desired location on the pad is provided. The fluid guide may include an elongate member with a proximal end coupled to an upper surface on the menstrual pad and a distal end extending forward towards the front end of the menstrual pad. The distal end of the elongate member may be placed against or inside the user's vagina. In this way, the fluid guide member may guide menstrual fluid to the desired location on the pad, thereby minimizing leakage of the fluid out the sides, rear, or front of the pad.
