Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lash adhesives contain chemicals like acrylates, formaldehyde, and latex, which can cause irritation and allergic reactions, necessitating careful application in well-ventilated areas and limiting user comfort.
Innovation Solution
Adhesive compositions incorporating an acrylate component and charcoal, which provide antibacterial and antimicrobial properties, are developed to reduce irritation and allergic reactions, while maintaining adhesive strength and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional chemicals (acrylates, formaldehyde, latex) are used in lash adhesives, then adhesive strength is achieved, but irritation and allergic reactions occur
Solution Approach 1:
The patent removes harmful chemicals (formaldehyde, latex, and certain acrylates) from the adhesive composition while retaining effective bonding agents. This extraction of toxic components eliminates the source of irritation and allergic reactions while maintaining adhesive functionality through alternative safe ingredients.
Solution Approach 2:
The invention uses a composite adhesive formulation combining safe acrylate copolymers, water, and charcoal. This composite material approach allows the adhesive to achieve necessary bonding strength through synergistic interactions between components while avoiding harmful substances, thus resolving the contradiction between strength and safety.
2Strength
If conventional adhesives are applied near eyes, then bonding is achieved, but user comfort is reduced due to irritation
Solution Approach 1:
The patent incorporates charcoal into the adhesive formulation, which not only serves as a safe alternative to harmful chemicals but also provides antibacterial and antimicrobial properties. This converts a potentially problematic ingredient into a beneficial component that enhances both safety and user comfort while maintaining bonding capability.
3Object-affected harmful factors
If adhesive compositions are made safer by removing chemicals, then irritation is reduced, but adhesive strength may be compromised
Solution Approach 1:
The patent modifies the chemical parameters of the adhesive by changing the type and concentration of acrylate copolymers used. By selecting specific safe acrylate copolymers and optimizing their concentration, the formulation achieves both reduced irritation and maintained adhesive strength, resolving the contradiction between safety and performance.
