Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning articles, such as rags, paper towels, and nonwoven sheets, face issues with hygiene, reach, and convenience, particularly when cleaning hard surfaces, and previous attempts at using soy oil coatings for cleaning articles have not effectively balanced cleaning efficacy with processability, often leading to residue and contamination.
Innovation Solution
A cleaning article with a soy oil coating having less than 45% hydrogenation, resulting in an iodine value greater than 90, which enhances debris retention without compromising manufacturing processability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If soy oil coating with high hydrogenation is used, then manufacturing processability is improved, but cleaning efficacy deteriorates due to residue and contamination
Solution Approach 1:
The patent applies parameter changes by precisely controlling the hydrogenation level of soy oil to less than 45% (iodine value greater than 90), transforming the coating properties to achieve both manufacturability and cleaning efficacy. This specific parameter range resolves the contradiction by finding the optimal balance point where the coating is not too soft to cause residue but not too hard to compromise debris retention.
Solution Approach 2:
The patent uses composite materials by combining soy oil with specific polymers and additives to create a coating formulation that achieves both processability and cleaning performance. The composite structure allows the coating to have appropriate viscosity for manufacturing while maintaining effective debris retention properties through the synergistic interaction of components.
2Reliability
If soy oil coating with low hydrogenation is used, then cleaning efficacy is improved, but manufacturing processability deteriorates due to contamination and residue
Solution Approach 1:
The patent resolves this contradiction by establishing the critical parameter threshold of less than 45% hydrogenation (iodine value greater than 90). This parameter change transforms the soy oil properties to achieve superior cleaning efficacy while the specific formulation and application process ensure manufacturing processability is maintained through controlled coating deposition.
Solution Approach 2:
The patent applies copying by using a coating formulation that replicates the desirable properties of fully hydrogenated soy oil (processability) while incorporating unsaturated components (cleaning efficacy). The coating composition is designed to copy the beneficial aspects of both extreme hydrogenation levels without suffering from their respective drawbacks.
3Ease of manufacture
If conventional coatings are used, then manufacturing is simplified, but debris retention capability is insufficient
Solution Approach 1:
The patent uses composite materials by formulating a coating that combines soy oil with polymers and functional additives. This composite structure provides both the simplicity of conventional single-component coatings in terms of application process and the enhanced debris retention capability through the synergistic properties of multiple components working together.
Solution Approach 2:
The patent applies parameter changes by modifying the chemical composition parameters of the coating, specifically the hydrogenation level of soy oil and the ratios of various components. These parameter adjustments enhance debris retention capability while maintaining manufacturing simplicity through a single-step coating application process.

AI summary
A cleaning article for cleaning a target surface. The cleaning article has a coating of soy oil, to improve debris capture and retention. The soy oil is substantially un-hydrogenated, which further improves processability, without sacrificing debris capture and retention over commonly used and more highly hydrogenated soy oil.
