Solution Overview
Problem
Conventional slip preventing agents for socks cause a sticky feeling and leave residue on the skin, leading to an unpleasant experience during and after use.
Innovation Solution
A slip preventing agent comprising an acrylic acid-based polymer, glycerin, and fatty acid dextrin, formulated to provide adequate adhesion while minimizing sticky feelings and residue, with specific ratios of these components to achieve a dry touch and improved user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional adhesive composition is used to prevent sock slipping, then adhesion performance is improved, but sticky feeling increases
Solution Approach 1:
The patent changes the chemical composition parameters by incorporating specific ratios of acrylic acid-based polymer (0.01-10 mass%), glycerin (0.1-80 mass%), and fatty acid dextrin (0.05-1 mass%). This parameter optimization allows the composition to maintain adhesion while reducing sticky feeling through controlled viscosity and drying characteristics.
Solution Approach 2:
The patent uses a composite material system combining three distinct components: acrylic acid-based polymer for adhesion, glycerin for moisture control and flexibility, and fatty acid dextrin for texture modification. This composite approach enables simultaneous achievement of adhesion performance and reduced sticky feeling that cannot be obtained with single materials.
2Reliability
If a large amount of slip preventing agent is applied to ensure adhesion, then sock slipping is prevented, but residue on skin increases
Solution Approach 1:
The patent optimizes the concentration parameters of each component to achieve maximum adhesion efficiency at minimal effective doses. The specific ratio ranges ensure that the active adhesive components are present in sufficient quantities for slip prevention while minimizing total composition amount and subsequent residue.
Solution Approach 2:
The patent extracts and isolates the essential adhesive function into specific polymer components (acrylic acid-based polymer) while using glycerin and fatty acid dextrin to modify the composition's behavior. This extraction allows the active ingredient to work efficiently at low concentrations, reducing unnecessary residue on skin after sock removal.
