Adhesive Shell for Discreet Feminine Care Absorbent Article
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles are uncomfortable to wear due to their design, which can cause bunching or twisting, leading to discomfort and leakage, and they lack discretion as they may be visible through clothing, failing to provide effective protection against premature leakage.
Innovation Solution
A feminine care absorbent article with a shell that has a body-facing surface with adhesive for direct adherence to the wearer, designed to fit anatomically around the vaginal region, providing a comfortable and discreet solution that prevents leakage by extending outward beyond the absorbent structure to ensure secure attachment and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If absorbent articles are attached to underwear or undergarment, then they can be held in place during use, but they may become bunched or twisted during body movement causing discomfort and leakage
Solution Approach 1:
The patent introduces a shell as an intermediary component between the absorbent structure and the wearer's body. The shell has a body-facing surface with adhesive that directly adheres to the wearer, while the absorbent structure is contained within the shell. This intermediary shell prevents direct attachment of the absorbent article to underwear, eliminating bunching and twisting issues while maintaining secure attachment through the adhesive on the body-facing surface.
2Ease of manufacture
If absorbent articles are designed with conventional shapes and sizes, then they can be manufactured easily, but they may be visible through tight fitting clothing lacking discretion
Solution Approach 1:
The patent employs a shell structure that is thin and flexible, designed to conform to the body's contours. The shell has a body-facing surface and a garment-facing surface, creating a thin profile that minimizes visibility through tight-fitting clothing. This shell structure maintains manufacturing simplicity while providing the desired discretion by creating a sleek, body-contouring form factor.
3Reliability
If adhesive is applied to the body-facing surface of the top sheet, then the absorbent article can adhere to the skin, but the design remains the same as articles attached to underwear lacking comfort improvement
Solution Approach 1:
The patent segments the absorbent article into distinct components: a shell with a body-facing surface containing adhesive, and an absorbent structure contained within the shell. The adhesive is specifically applied to the body-facing surface of the shell, separating the adhesion function from the absorbent structure. This segmentation allows the adhesive to provide secure skin attachment while the shell structure provides comfort and prevents bunching, resolving the contradiction between adhesion reliability and wearability comfort.
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 absorbent article provides enhanced comfort, discretion, and effective leakage protection by adhering directly to the body, preventing bunching and twisting, while ensuring the absorbent structure is securely positioned to manage bodily fluids effectively.
Implementation Method 1
The body-facing surface has an adhesive thereon for adhering the shell directly to the wearer
Implementation Method 2
an absorbent structure configured for disposition adjacent a female wearer's vaginal region to absorb bodily fluids discharged by the wearer
Data Source
AI summary
A feminine care absorbent article has an absorbent structure configured for disposition adjacent a female wearer's vaginal region to absorb bodily fluids discharged by the wearer, and a shell for supporting the absorbent structure at the vaginal region. The shell has a body-facing surface and a garment-facing surface. The body-facing surface has an adhesive thereon for adhering the shell directly to the wearer. The shell has a longitudinal axis, a transverse axis, an anterior region, a posterior region, and a central region extending longitudinally between and interconnecting the anterior and posterior regions. The anterior region of the shell includes a longitudinal edge having a longitudinal extent from the transverse axis. The longitudinal extent increases as the longitudinal edge extends transversely outward from the longitudinal axis of the shell.
