Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbent articles have limited effectiveness in reducing a wide variety of malodors, as current odor control systems can only counteract a limited range of malodorous compounds.
Innovation Solution
An absorbent article with an odor control system comprising a specific mixture of alcohols, aldehydes, and acetates, such as 2-phenylethanol, terpineol, piperonal, benzyl acetate, and geranyl acetate, which reduces malodor unpleasantness through absorption, reaction, volatility suppression, and inhibition of microorganism activity, providing comprehensive odor reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single type of odor control material (e.g., zeolite, silica, or activated carbon) is used, then the manufacturing process is simple and cost-effective, but the effectiveness in reducing a wide variety of malodors is limited
Solution Approach 1:
The patent employs composite materials by combining multiple odor control agents (zeolite, silica, activated carbon, and other materials) into a single functional system. This composite approach allows the system to address a broad spectrum of malodorous compounds through the complementary mechanisms of each material, thereby resolving the contradiction between manufacturing simplicity and odor control versatility.
Solution Approach 2:
The odor control system is designed with multi-functionality by incorporating materials that work through different mechanisms (physical adsorption, chemical reaction, biological degradation). This universal design enables a single system to effectively handle various types of odors from different sources (urine, feces, sweat, etc.), achieving both ease of manufacture and broad odor control effectiveness.
2Adaptability or versatility
If multiple odor control materials are combined to broaden the range of malodors reduced, then odor control effectiveness improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges multiple odor control materials into an integrated system where zeolite, silica, activated carbon, and other agents work together in a unified structure. This combining approach achieves broad-spectrum odor control while managing system complexity through coordinated functionality rather than separate independent systems.
Solution Approach 2:
The patent utilizes porous materials (zeolite, silica, activated carbon) that provide high surface area and multiple adsorption sites within a unified structure. This porous material approach enables complex odor control functionality to be achieved through the inherent properties of the materials rather than through complex system architecture, thereby reducing device complexity while maintaining effectiveness.
3Ease of manufacture
If conventional odor control materials are used, then the manufacturing cost is lower, but the comprehensive odor reduction capability is insufficient
Solution Approach 1:
The patent creates a cost-effective composite material system that combines multiple odor control agents (zeolite, silica, activated carbon, etc.) where each component contributes to the overall performance. This composite approach achieves comprehensive odor reduction capability while managing manufacturing costs by selecting materials that are effective yet economically viable.
Solution Approach 2:
The patent optimizes the parameters of the odor control system by adjusting the types, ratios, and configurations of the various materials used. This parameter optimization enables the system to achieve high reliability in odor reduction while maintaining cost-effectiveness through efficient material selection and proportioning.
