Solution Overview

Problem

Existing hygiene pads are made from non-biodegradable materials, contributing significantly to ocean pollution and landfill waste, and their production requires excessive water consumption and generates pollution.

Innovation Solution

A biodegradable hygiene pad composed of at least 75% bamboo in the absorbent layer, upper and lower liners, and a biodegradable back sheet, along with biodegradable adhesives and packaging, ensuring structural integrity and fluid retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If non-biodegradable materials are used in hygiene pads, then fluid retention reliability is improved, but environmental pollution and waste accumulation worsen

Engineering Contradiction:
Improvefluid retention reliabilityVSAvoidenvironmental pollution
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material composition parameters by using at least 75% bamboo in the absorbent layer and upper liner, replacing traditional non-biodegradable materials with biodegradable bamboo-based materials while maintaining fluid retention performance

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite material structures combining bamboo fibers with biodegradable adhesives and coatings to create an absorbent layer that achieves both reliability in fluid retention and biodegradability for environmental sustainability

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If cotton is used in hygiene pads, then absorbency is improved, but water consumption and pollution during production worsen

Engineering Contradiction:
ImproveabsorbencyVSAvoidwater consumption
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent substitutes cotton with bamboo as the primary material in the absorbent layer and upper liner, changing the material parameter while achieving comparable or superior absorbency with reduced water consumption during production

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs disposable biodegradable bamboo-based materials that can be discarded after use, eliminating the need for washing and reuse, thereby reducing water consumption associated with cleaning traditional cotton products

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Object-generated harmful factors

If biodegradable materials are used in hygiene pads, then environmental impact is reduced, but structural integrity may worsen

Engineering Contradiction:
Improveenvironmental impactVSAvoidstructural integrity
Core Design Contradiction:
Object-generated harmful factorsVSStrength

Solution Approach 1:

The patent employs composite material structures combining bamboo fibers with biodegradable adhesives and coatings to create an absorbent layer that achieves both reliability in fluid retention and biodegradability for environmental sustainability

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies different material compositions to different layers - the absorbent layer and upper liner use at least 75% bamboo for biodegradability, while the back sheet uses different biodegradable materials optimized for leakproofing and structural support

Inventive Principle:
Principle #3Local quality
