Solution Overview

Problem

The challenge lies in creating disposable pant-type absorbent articles that provide increased comfort and fit for both male and female users while maintaining a discrete underwear-like appearance, while also minimizing manufacturing costs due to anatomical differences between genders and the need for distinct products.

Innovation Solution

The solution involves designing gender-specific absorbent articles with varying core area ratios and side elastic member positions to better accommodate urine discharge patterns, along with identical absorbent inserts and panels to simplify manufacturing and reduce costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If different products are designed for males and females to accommodate anatomical differences, then comfort and fit are improved, but manufacturing costs increase due to requiring different manufacturing apparatuses

Engineering Contradiction:
Improvecomfort and fitVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent applies local quality by making specific localized modifications to the absorbent core configuration and side elastic member positioning while keeping the overall product structure and manufacturing process the same. Female-oriented articles have a smaller front core area and rearward-positioned side elastic members, while male-oriented articles have a larger front core area and forward-positioned side elastic members. These localized changes accommodate anatomical differences without requiring entirely different manufacturing apparatuses.

Inventive Principle:
Principle #3Local quality

2Reliability

If gender-specific design features are added to accommodate anatomical differences, then leakage protection is improved, but device complexity increases

Engineering Contradiction:
Improveleakage protectionVSAvoidproduct design complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements leakage protection through localized modifications rather than overall redesign. The side elastic members are positioned at different longitudinal locations and the absorbent core has different front-to-back area ratios depending on gender orientation. These localized quality differences provide gender-specific leakage protection while maintaining relatively simple overall product design.

Inventive Principle:
Principle #3Local quality
