Adjustable Absorbent Article Chassis for Multi-Size Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current absorbent articles suffer from improper fit and comfort issues due to multiple sizes that do not accommodate varying body sizes, leading to skin irritation, leakage, increased manufacturing costs, and inefficiencies in production processes.
Innovation Solution
A rectangular chassis design with adjustable securement portions and elastic panels that accommodate a wide range of body sizes, reducing the need for multiple sizes and minimizing manufacturing downtime, while ensuring a comfortable fit and reducing skin trauma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sizes are produced to accommodate different body sizes, then fit and comfort are improved, but manufacturing complexity and downtime increase
Solution Approach 1:
The absorbent article is designed with a universal chassis and securement system that can accommodate multiple body sizes through adjustable components rather than requiring completely different sized articles. The elastic panels and adjustable securement portions allow a single article design to serve multiple size requirements.
Solution Approach 2:
The article incorporates dynamic elements such as elastic panels and adjustable securement portions that can be configured to fit different body sizes. These components allow the article to adapt its dimensions and fit characteristics to match various user requirements without changing the fundamental article structure.
2Adaptability or versatility
If multiple sizes are produced to accommodate different body sizes, then fit and comfort are improved, but manufacturing downtime increases
Solution Approach 1:
The absorbent article is designed with a universal chassis and securement system that can accommodate multiple body sizes through adjustable components rather than requiring completely different sized articles. The elastic panels and adjustable securement portions allow a single article design to serve multiple size requirements.
Solution Approach 2:
The manufacturing process is designed to maintain continuous production by using a universal chassis that eliminates the need for frequent machine reconfiguration. The adjustable securement portions and elastic panels can be configured for different sizes without stopping production or changing major machine components, thereby reducing downtime between size changes.
3Device complexity
If larger garments are used to accommodate all sizes, then manufacturing simplicity is improved, but comfort and fit deteriorate
Solution Approach 1:
The article is divided into a universal chassis and separate adjustable securement portions. This segmentation allows the main body of the article to remain consistent for manufacturing simplicity while the securement portions can be adjusted or configured to fit different body sizes and shapes, providing both comfort and manufacturing efficiency.
Solution Approach 2:
Different portions of the article have different levels of adjustability. The chassis provides a consistent base structure for manufacturing simplicity, while the securement portions and elastic panels provide localized adjustability to accommodate different body sizes and shapes, ensuring comfort without requiring complete size variations.
4Adaptability or versatility
If stretch material is extended fully to accommodate larger waist sizes, then adaptability is improved, but skin irritation increases
Solution Approach 1:
The article uses elastic panels with controlled elasticity parameters that can accommodate waist size variations within a safe range. By carefully selecting the elastic properties and maximum extension limits, the article provides adaptability for different waist sizes while preventing over-stretching that would cause skin irritation or trauma.
Solution Approach 2:
The securement portions are designed with pre-compression characteristics that distribute pressure evenly across the waist area. This beforehand cushioning prevents concentrated stress points that would occur with excessive stretching, thereby protecting the skin from irritation while still accommodating larger waist sizes through the elastic panels.

AI summary
An absorbent article includes a chassis having a substantially rectangular shape a first portion, a second portion and a crotch portion extending between the first and second portion, a portion of the chassis being configured to absorb fluids. The absorbent article includes a first securement portion operatively coupled to the first portion of the chassis. The absorbent article includes a second securement portion operatively coupled to the second portion of the chassis and configured to releasably attach to the first securement portion. The chassis is configured to include one of a first chassis length or a second chassis length. When the chassis includes the first length, the chassis includes a first width and the first securement portion includes a second width, and when the chassis includes the second length, the chassis includes the first width and the first securement portion includes a third width, greater than the second width.
