Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tampons fail to provide a localized fit to the individual contours of the vaginal wall, leading to premature leakage and integrity issues due to their uniform construction and material constraints, which limits their ability to adapt to local deformation and fluid acquisition effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current tampons use uniform construction and material constraints, then manufacturing is simplified, but the tampon cannot adapt to local contours of the vaginal wall, causing premature leakage
Solution Approach 1:
The tampon is divided into multiple discrete contact elements rather than a uniform continuous structure. Each contact element can independently deform and conform to local vaginal wall contours, while the elements remain connected through a flexible matrix. This segmentation enables localized adaptation without requiring complete structural complexity.
Solution Approach 2:
The tampon incorporates contact elements with different local properties - some elements are more compliant for conforming to contours, while others provide structural support. The flexible matrix has varying density and connectivity to allow local deformation while maintaining overall integrity. This local quality differentiation resolves the contradiction between adaptability and complexity.
2Manufacturing precision
If tampons are made with uniform construction, then manufacturing precision is easier to maintain, but they cannot provide localized fit, leading to leakage
Solution Approach 1:
By segmenting the tampon into discrete contact elements, each element can be manufactured with consistent properties using standardized processes. The modular nature allows for precise control of each element's characteristics while maintaining overall manufacturing consistency through repetition of the same manufacturing steps for each element.
Solution Approach 2:
The flexible matrix material properties are adjusted to allow controlled deformation of contact elements. The material parameters are selected to provide both compliance for local adaptation and sufficient structural integrity for reliable fluid containment, resolving the contradiction between manufacturing consistency and leakage prevention.
3Adaptability or versatility
If tampons use material connectivity and stiffness, then structural integrity is maintained, but the entire tampon responds uniformly to local forces, preventing local adaptation
Solution Approach 1:
The tampon structure is segmented into discrete contact elements connected by a flexible matrix. This segmentation allows local deformation of individual elements in response to local forces while the overall structural integrity is maintained through the connecting matrix. Each element can adapt locally without forcing uniform response across the entire tampon.
Solution Approach 2:
The flexible matrix acts as a thin film connecting the contact elements, providing sufficient structural integrity to maintain tampon shape while allowing local flexibility for element deformation. The matrix material is selected to balance strength and flexibility, enabling local adaptation while preventing structural failure.
4Adaptability or versatility
If attempts are made to allow more local adaptation, then contact area increases, but integrity issues arise causing portions to remain in vagina after removal
Solution Approach 1:
The segmented structure of discrete contact elements allows each element to conform locally to vaginal contours, increasing contact area. The elements remain connected through the flexible matrix, which maintains overall structural integrity and ensures complete removal of the tampon. The segmentation enables local adaptability without sacrificing global integrity.
Solution Approach 2:
Different regions of the tampon have optimized local properties - contact elements provide local conformability for increased contact area, while the flexible matrix provides structural continuity for integrity maintenance. This local quality differentiation allows the tampon to achieve both local adaptation and reliable removal without fragmentation.

AI summary
A method of manufacturing a tampon generally comprises forming a softwind including a core and a cover overlying and at least in part covering the core. The cover carries an absorbent web having a free end and a bonded end wherein the free end is capable of moving relative to the cover. The softwind is passed through a transfer assist device to facilitate the transferring of the free end of the absorbent web without the absorbent web becoming misaligned relative to the cover.
