Absorbent Article Hip-to-Waist Silhouette Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current absorbent articles fail to adequately fit a broad range of consumers due to their inability to conform to various body shapes and sizes, leading to issues with leakage, comfort, and discretion, as they are typically designed using only weight and waist circumference as sizing criteria, neglecting the varying ratios of body anthropometrics across different age and weight groups.
Innovation Solution
The development of disposable absorbent articles that are designed to match the Hip-to-Waist Silhouette of the target consumer, adjusting the Product Hip-to-Waist Silhouette to match the Body Hip-to-Waist Silhouette across different sizes, ensuring a better fit, comfort, and gasketing by using a combination of elastic materials and design features that accommodate different body shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If absorbent articles are designed using only weight and waist circumference as sizing criteria, then manufacturing and sizing is simplified, but fit and comfort deteriorate due to inability to account for varying body shapes
Solution Approach 1:
The patent applies local quality by varying the hip-to-waist silhouette ratio across different size categories within the same product line. Instead of uniform scaling, each size is specifically designed with adjusted hip and waist dimensions to match the anatomical characteristics of target consumer groups (infants vs. adults), providing localized fit optimization for different body shapes while maintaining overall manufacturing simplicity through a systematic sizing framework.
2Reliability
If the product hip-to-waist silhouette is adjusted to match body hip-to-waist silhouette across different sizes, then fit and comfort are improved, but device complexity increases due to multiple design parameters
Solution Approach 1:
The patent implements parameter changes by systematically adjusting the hip-to-waist silhouette ratio as a key design parameter across different size categories. This involves changing the relative proportions of hip width and waist width dimensions to match anthropometric data for different consumer groups, thereby optimizing fit through controlled parameter variation rather than complete redesign of each size category.
Solution Approach 2:
The patent applies segmentation by dividing the product line into distinct size categories (e.g., infant sizes vs. adult sizes) with specific hip-to-waist silhouette ratios tailored to each segment's target demographic. This segmentation allows complex anatomical variations to be addressed through manageable, standardized size categories rather than continuous customization.
3Reliability
If elastic forces are increased to improve gasketing, then leakage is reduced, but comfort deteriorates due to skin marking and tight fit
Solution Approach 1:
The patent applies local quality by differentiating elastic force application across different body regions and size categories. The hip-to-waist silhouette design creates optimized force distribution where elastic forces are concentrated at the hips (anchoring point) rather than uniformly distributed around the waist. This localized force application improves gasketing effectiveness at critical areas while reducing excessive force on sensitive skin areas, thereby minimizing skin marking.
