Absorbent articles having a belt portion with a texture zone having a texture ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles, such as diapers, lack an aesthetically pleasing appearance and comfortable fit, particularly in the belt portion, which does not provide an improved fit or feel without increasing manufacturing costs.
Innovation Solution
Incorporating a belt portion with a texture zone having a texture ratio greater than 5 and less than 25, achieved by combining substrates with elongate elastic elements, which form a single uniform texture or multiple texture zones, enhancing the fit and appearance while resembling clothing or underwear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a texture zone with high texture ratio is incorporated into the belt portion, then aesthetic appearance and comfortable feel are improved, but manufacturing complexity increases
Solution Approach 1:
The belt portion is divided into a texture zone and a non-texture zone, allowing the complex texture features to be localized only where needed for aesthetic and comfort purposes, while the rest of the belt maintains simple construction for easy manufacturing
Solution Approach 2:
The texture zone is confined to a specific portion of the belt rather than the entire belt, applying the complex texture structure only where aesthetic appearance and comfortable feel are required, while maintaining simple structure elsewhere
2Reliability
If elastic elements are added to create texture zones, then fit and appearance are improved, but device complexity increases
Solution Approach 1:
Elastic elements are incorporated only within the texture zone of the belt portion, providing improved fit and appearance characteristics specifically where needed, while the rest of the belt maintains simpler construction
Solution Approach 2:
The belt portion combines different materials including substrates and elastic elements in a composite structure, where the elastic elements provide the desired fit and texture characteristics when integrated with the substrate material

Function Achieved in This Case
The solution provides an improved fit and aesthetically pleasing appearance for absorbent articles, enhancing comfort and resemblance to clothing without significant cost increases, by utilizing a belt portion with a controlled texture ratio and elastic elements.
Implementation Method 1
a plurality of elongate elastic elements disposed at least partially intermediate the first substrate and the second substrate
Data Source
AI summary
The present disclosure is directed, in part, to an absorbent article comprising a chassis comprising a topsheet, a backsheet, and a core disposed at least partially intermediate the topsheet and the backsheet. The absorbent article comprises a belt portion extending from the chassis. The belt portion comprises a first substrate, a second substrate joined to the first substrate, and a plurality of elongate elastic elements disposed at least partially intermediate the first substrate and the second substrate. The belt portion comprises a texture zone having a texture ratio of greater than about 5.
