Hip-to-Side Silhouette Design for Disposable Absorbent Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disposable absorbent articles fail to adequately fit a broad range of users due to their design not accounting for varying body shapes and sizes, leading to issues like slipping, sagging, and leakage, especially for individuals with urinary incontinence.
Innovation Solution
The development of absorbent articles with a higher Product Hip-to-Side Silhouette ratio, similar to bikini or hipster underwear, which provides a more tailored fit by anchoring at the waist and hips, reducing the side seam length and increasing the Product Hip-to-Side Silhouette, thereby enhancing leakage protection and discretion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Relaxed Product Side Length is increased to provide broader anchoring band, then anchoring force is improved, but the product becomes more constricting and less comfortable
Solution Approach 1:
The patent applies local quality by concentrating anchoring forces at specific anatomical locations (waist and hip circumferences) rather than distributing them uniformly along a broad side length. The absorbent article is designed with targeted anchoring bands at the waist and hip regions, allowing effective anchoring with shorter side lengths, thereby improving comfort while maintaining reliability.
2Ease of operation
If the Relaxed Product Side Length is decreased to improve discretion, then anchoring band becomes narrower, but anchoring force may be reduced
Solution Approach 1:
The patent changes the parameter of side length to be shorter than conventional products, while compensating for anchoring force through strategic placement at anatomical landmarks. The Product Hip-to-Side Silhouette ratio is optimized to ensure adequate anchoring despite reduced side length, maintaining both discretion and reliability.
3Quantity of substance
If excessive material is used in the absorbent article, then absorption capacity is improved, but sagging and bunching in the crotch occurs
Solution Approach 1:
The patent applies dynamics by making the absorbent article extensible and adaptable to body movements. The product includes elastic elements and flexible materials that allow the article to stretch and conform to the wearer's body during movement, preventing sagging and bunching while maintaining absorption capacity.
4Reliability
If the product is designed to fit tightly at waist and hips, then gasketing is improved, but the product may be more difficult to apply
Solution Approach 1:
The patent applies preliminary action by pre-forming the absorbent article with curved side edges that naturally guide the product into proper positioning on the wearer's body. The waist and hip contours are pre-shaped to align with anatomical landmarks, facilitating easier application while ensuring tight fit and effective gasketing.
