Sanitary Pad Raised Portion Vestibule Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanitary pads tend to move away from the vaginal orifice due to compressive forces, leading to potential leakage of mensural fluid and soiling of garments, as they are not securely aligned with the vestibule.
Innovation Solution
A sanitary pad design featuring a raised portion centrally positioned to be inserted within the vestibule for absorption, along with peripheral barriers and grooves to secure the pad in place, and an additional raised portion for the anal region to prevent movement and ensure leak-proof alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sanitary pad is used, then the pad is simple in structure and easy to manufacture, but the pad moves away from the vaginal orifice due to compressive forces, leading to leakage
Solution Approach 1:
The sanitary pad is divided into multiple functional zones: a first raised portion for vestibule insertion, a second raised portion for anal region insertion, peripheral barriers, and grooves. This segmentation allows each portion to address specific movement issues in different regions, preventing leakage while maintaining manageable structural complexity
Solution Approach 2:
The patent introduces vertical dimension by creating raised portions that extend outwardly from the pad surface. These raised portions can be inserted into the vestibule and anal region respectively, adding a third dimension (depth insertion) to the traditional two-dimensional pad layout, thereby securing the pad in place against compressive forces
2Stability of the object's composition
If the pad is made with raised portions for insertion, then the pad alignment and securing is improved, but the manufacturing complexity increases
Solution Approach 1:
The raised portions are pre-formed as integral parts of the pad during manufacturing, creating ready-to-insert structures that guide proper positioning. The peripheral barriers and grooves are also pre-configured to work together with the raised portions, establishing alignment and securing mechanisms before the pad reaches the user
Solution Approach 2:
Multiple functional features (raised portions, peripheral barriers, grooves) are merged into a single integrated pad structure. This combining of features into one piece allows for streamlined manufacturing while achieving complex alignment and securing functions that would be difficult to accomplish with separate components
3Reliability
If the pad is designed with multiple raised portions and peripheral barriers, then the leak-proof alignment is achieved, but the device complexity increases
Solution Approach 1:
Different portions of the pad are given different local characteristics: the first raised portion is optimized for vestibule insertion, the second raised portion for anal region insertion, peripheral barriers provide localized containment, and grooves provide localized fluid channeling. This local quality differentiation achieves comprehensive leak-proof alignment without requiring the entire pad to be overly complex

AI summary
A sanitary pad for absorbing the human exudate is disclosed. The sanitary pad includes a first surface, a second surface disposed opposite to the first surface, and a raised portion disposed substantially centrally to the sanitary pad and extending outwardly from the first surface. The raised portion is adapted to be inserted, at least partially, within a vestibule of a wearer to facilitate an absorption of mensural fluid of a wearer. Also, the insertion of the raised portion facilitates an alignment and securing of the sanitary pad with the vestibule.
