Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing false eyelash glues cause eye irritation, allergic reactions, and conjunctival damage due to chemical ingredients like acrylic acid copolymers, propylene glycol, sodium dehydroacetate, laureth-20, hydroxyethyl cellulose, methylparaben, and Arabic gum, posing risks for users, especially those with sensitive eyes or eye diseases.
Innovation Solution
Self-adhesive false eyelashes made with a gelatin-carrageenan-Pullulan composite formula, using food-grade gelatin, carrageenan, and Pullulan, which form a stable, non-irritating adhesive that can be reused, providing strong adhesion and environmental compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If false eyelash glue containing chemical ingredients (acrylic acid copolymers, propylene glycol, sodium dehydroacetate, laureth-20, hydroxyethyl cellulose, methylparaben, Arabic gum) is used, then adhesion stability is improved, but eye irritation and allergic reactions occur
Solution Approach 1:
The patent extracts and removes harmful chemical ingredients from the adhesive system. Specifically, it eliminates acrylic acid copolymers, propylene glycol, sodium dehydroacetate, laureth-20, hydroxyethyl cellulose, methylparaben, and Arabic gum that cause eye irritation and allergic reactions, replacing them with safe alternatives like hydrogel material and magnesium hydroxide micro-powder.
Solution Approach 2:
The patent changes the chemical composition parameters of the adhesive by substituting harmful chemicals with safe materials. The adhesive layer transitions from containing irritants to comprising hydrogel base material with specific safe ingredients, fundamentally altering the chemical parameters while maintaining adhesion functionality.
2Strength
If false eyelash glue is used for stable adhesion, then connection strength between false eyelashes and eyelids is improved, but the glue cannot be reused and poses safety risks for long-term use
Solution Approach 1:
The patent inverts the traditional disposable model by creating reusable false eyelashes. Instead of discarding the adhesive after single use, the hydrogel-based adhesive allows multiple applications while maintaining safety and effectiveness, eliminating the need for continuous purchase of new glue products.
Solution Approach 2:
The false eyelashes are designed with self-adhesive properties through the hydrogel layer that can repeatedly adhere and release without external assistance. The adhesive system serves itself by maintaining its bonding capability across multiple uses without requiring replenishment or replacement.
3Ease of operation
If Arabic gum is used in false eyelash glue to provide adhesion, then adhesive property is improved, but allergic reactions and eye discomfort occur
Solution Approach 1:
The patent converts the problematic adhesive function previously provided by harmful Arabic gum into a beneficial function performed by safe hydrogel material. The hydrogel provides equivalent or superior adhesion while simultaneously protecting against allergic reactions and eye discomfort, turning a harmful adhesive solution into a beneficial one.
Solution Approach 2:
The patent creates a composite adhesive system using hydrogel base material combined with safe ingredients like magnesium hydroxide micro-powder. This composite material achieves the desired adhesive properties while eliminating the allergenic effects of pure Arabic gum, combining multiple safe components for optimal performance.
