Solution Overview

Problem

Existing absorbent articles with a 'balloon' pant design face challenges in creating a holistic appearance by seamlessly integrating graphics across multiple components, which are often masked by seams, leading to a less aesthetically pleasing and functional product.

Innovation Solution

The design minimizes the distance between graphic objects and seams on absorbent article components, allowing for precise placement and alignment to create a unified, seam-deemphasized structure, using techniques such as printing graphics on both the central chassis and belt portions, ensuring that graphic objects are either entirely on one component or overlap minimally, thus enhancing the appearance and masking process variations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If graphics are placed on multiple absorbent article components (central chassis and belt), then the aesthetic appearance and holistic design are improved, but the seam noticeability increases and the integrated appearance deteriorates

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidseam noticeability
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent divides the graphic design into multiple segments corresponding to different article components (central chassis and belt portions). Each component receives appropriate graphic elements that are coordinated to form a complete design when assembled, allowing graphics to be placed on multiple components while managing seam visibility through strategic segmentation of the overall graphic pattern.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the distance between graphic objects and seams is minimized, then the seam masking effect is improved and integrated appearance is enhanced, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveintegrated appearanceVSAvoidgraphic placement precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies forGraphic objects are positioned and aligned on article components before the final assembly process. By pre-placing graphics on the central chassis and belt portions separately with predetermined positioning features, the system enables precise alignment during assembly without requiring extremely tight manufacturing tolerances on individual components.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces positioning features, alignment marks, or reference structures as intermediaries between the graphic objects and seams. These intermediary elements facilitate precise placement and alignment during manufacturing and assembly, reducing the direct dependency on high manufacturing precision while achieving the desired minimal distance between graphics and seams for effective masking.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If graphics flow cohesively across components, then the holistic underwear-like appearance is improved, but the difficulty of detecting and measuring alignment increases

Engineering Contradiction:
Improveholistic appearanceVSAvoidalignment measurement
Core Design Contradiction:
Illumination intensityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent employs consistent graphic patterns, colors, or design elements that are replicated or coordinated across different article components. By using copying of design motifs or continuous patterns that wrap around seams, the system creates a cohesive holistic appearance while providing reference points that simplify alignment verification during quality control.

Inventive Principle:
Principle #26Copying
