Solution Overview

Problem

Current disposable absorbent pants with a belt configuration, designed for refastenability, are complex to produce at high speeds and may have a rough appearance, making them inefficient and difficult to use.

Innovation Solution

The design incorporates fastening components, such as hooks and loops, integrated into the elasticized belt to create a refastenable feature, allowing for easier opening and reclosing while maintaining manufacturing efficiency and appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If refastenable features are incorporated into belt configuration pants, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of opening and reclosingVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The fastening components are merged with the elasticized belt structure, where the belt itself serves as both the closure mechanism and the fastening system. The ends of the elasticized belt are configured to overlap and engage with each other directly, eliminating the need for separate complex fastening mechanisms while maintaining refastenable functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elasticized belt performs multiple functions: it provides waist adjustment, forms the waist opening, and simultaneously serves as the refastenable closure system. The overlapping ends of the belt can be engaged and disengaged to allow opening and reclosing, combining several functions into a single structural element.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If refastenable features are incorporated into belt configuration pants, then ease of operation is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveease of opening and reclosingVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The manufacturing process merges the formation of the elasticized belt and the refastenable closure into a single continuous operation. The elasticized belt is formed with its ends configured to overlap during the same manufacturing process, eliminating the need for separate assembly steps for attaching fastening components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elasticized belt is pre-formed during manufacturing with its ends positioned and configured to overlap and engage. This preliminary configuration of the fastening structure during belt formation simplifies the overall manufacturing process by preparing the refastenable feature in advance rather than requiring complex post-assembly operations.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If complex refastenable features are incorporated, then ease of operation is improved, but appearance quality deteriorates

Engineering Contradiction:
Improveease of opening and reclosingVSAvoidappearance quality
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The refastenable closure is merged with the elasticized belt structure, so the fastening mechanism is not a separate visible component but an integrated feature of the belt itself. The overlapping ends of the belt create a clean, finished appearance while maintaining the ability to open and reclose.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The refastenable feature is localized to the overlapping ends of the elasticized belt, allowing the rest of the pant to maintain a smooth, uniform appearance. The fastening function is concentrated in a specific area where it is needed, while the overall structure preserves aesthetic quality.

Inventive Principle:
Principle #3Local quality

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

The solution simplifies the production process and user experience by enabling quick and easy adjustment of the waist and leg openings, enhancing manufacturability and convenience without compromising the product's appearance.

Implementation Method 1

the encircling belt may be made elastically extensible in the lateral direction, providing stretchability that eases donning, while providing a relatively snug and comfortable fit once donned

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

This may be accomplished by incorporating for example mechanical fastening elements into the structure of the absorbent article as part of the belt-like structure

Methodology Applied
Scientific EffectMechanical Fastening: Mechanical Fastener
