Elastic Crotch Panel Absorbent Boxer Shorts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable absorbent boxer shorts face manufacturing challenges and compromised product design due to the need for high manufacturing speed, particularly in achieving comfort and fit in leg openings and hanging legs.
Innovation Solution
The use of elastic web material for the front, back, and crotch panels, where the crotch panel is wider than the front and back panels, with side seams extending into the crotch panel, and the crotch panel being either separate or integral with the other panels, to enhance fit and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high manufacturing speed is used to produce low-cost disposable absorbent articles, then productivity increases and cost decreases, but product design quality and comfort fit deteriorate
Solution Approach 1:
The garment shell is divided into separate panels (front body panel, back body panel, crotch panel) that can be manufactured and assembled efficiently. This segmentation allows for standardized production processes while maintaining design quality in each specific region.
Solution Approach 2:
The crotch panel is designed with specific local qualities including increased width (at least 7% larger than front and back panels) and elastic web material properties that provide enhanced comfort and fit in the critical crotch region, while other areas use standard design.
2Ease of operation
If the crotch panel width is increased to improve comfort and fit, then leg opening comfort improves, but manufacturing complexity increases
Solution Approach 1:
The crotch panel is manufactured as a separate piece with predetermined increased width, allowing the complexity to be built into the component design rather than the assembly process. This separate panel can be produced using standard elastic web material manufacturing processes.
Solution Approach 2:
The crotch panel width parameter is specifically increased to at least 7% larger than the front and back panels, and the material elasticity parameter is utilized to provide comfort. These parameter changes are incorporated into the standard manufacturing specifications for the separate crotch panel.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design improves the fit and comfort of absorbent boxer shorts by ensuring a wider crotch panel that is at least 7% larger than the front and back panels, providing better leg opening width and maintaining comfort and functionality.
Implementation Method 1
each of said front body panel, back body panel and crotch panel is made of elastic web material, the width of the crotch panel in a relaxed condition of the elastic web material, as measured between the side seams of the article, is at least 7% larger than the width of any of the front and back body panels

AI summary
An absorbent pant article in the form of boxer shorts includes a garment shell including a front body panel, a back body panel and a crotch panel made of elastic web material. The pant also includes an absorbent core, side seams connecting the front body panel to the back body panel, a pair of leg openings and hanging legs. The leg openings are located in the crotch panel and do not extend into the front and back body panels, and side seams extend into the crotch panel. The width of the crotch panel in a relaxed condition of the elastic web material, as measured between the side seams of the article, is at least 7% larger than the width of any of the front and back body panels in a relaxed condition of the respective elastic web material.
