Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
2Quantity of substance
If cotton is used in hygiene pads, then absorbency is improved, but water consumption and pollution during production worsen
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
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
3Object-generated harmful factors
If biodegradable materials are used in hygiene pads, then environmental impact is reduced, but structural integrity may worsen
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
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
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 biodegradable hygiene pad effectively absorbs bodily fluids while minimizing environmental impact by decomposing naturally, reducing waste and resource consumption.
Implementation Method 1
an absorbent layer; wherein the upper liner is arranged as a body side layer, wherein the absorbent layer is arranged between the upper liner and the lower liner
Implementation Method 2
The absorbent layer is highly absorbent and designed to absorb and retain liquid
