Absorbent Article Belt Texture Zone for Fit and Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles, such as diapers, lack an aesthetically pleasing appearance and comfortable fit due to the absence of a texture zone with a suitable texture ratio, which affects their overall performance and user experience.
Innovation Solution
Incorporating a belt portion with a texture zone having a texture ratio of greater than 5 and less than 25, achieved by combining substrates with elongate elastic elements, which provides an improved fit and appearance while resembling clothing or underwear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a texture zone with a texture ratio greater than 5 is incorporated into the belt portion, then the aesthetic appearance and comfortable feel are improved, but the device complexity increases due to the additional substrates and elastic elements
Solution Approach 1:
The patent combines multiple substrates (first substrate and second substrate) with elongate elastic elements into a single integrated belt portion assembly. This merging of components creates a unified structure that provides both aesthetic texture and functional elasticity, resolving the contradiction by integrating form and function into one manufacturable unit.
Solution Approach 2:
The belt portion utilizes a composite construction involving at least two different substrates combined with elastic elements. This composite approach allows the structure to simultaneously achieve desirable aesthetic properties through texture variation and functional properties through elastic recovery, while maintaining manufacturability through standardized composite material processes.
2Adaptability or versatility
If a texture zone with elongate elastic elements is added to provide fit and appearance, then the functionality and aesthetic appeal are improved, but the manufacturing cost increases
Solution Approach 1:
The belt portion is designed to serve multiple functions simultaneously: providing aesthetic appearance through texture zones, ensuring proper fit through elastic elements, and maintaining structural integrity through substrate construction. This multi-functionality reduces the need for separate components, thereby controlling manufacturing costs while achieving diverse performance requirements.
Solution Approach 2:
The patent optimizes the texture ratio parameter (defined as the ratio of textured area to total area) to fall within a specific range greater than 5, which balances aesthetic appearance with manufacturing efficiency. By establishing this quantitative parameter, the invention provides a clear design criterion that guides material selection and construction methods to achieve cost-effective production.
