Solution Overview
Problem
Existing nail tips can cause nail damage, hygiene issues, and infectious diseases due to adhesive use, and lack reusability.
Innovation Solution
A reusable nail tip design featuring a thermoplastic polyurethane (TPU) composite nail body and an adhesive layer comprising a styrene-isoprene-styrene (SIS) copolymer, propylene glycol, polyisobutene, carboxymethyl cellulose (CMC), silica, and zeolite, providing antibacterial and moisture properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adhesive materials are used to attach nail tips, then the nail tips can be securely attached to the natural nail, but nail damage and infectious skin diseases may occur
Solution Approach 1:
The adhesive layer composition is changed from conventional adhesives to a specific formulation containing SIS copolymer (25-35 parts), propylene glycol (15-25 parts), polyisobutene (10-20 parts), CMC (5-15 parts), silica (0.1-1 part), and zeolite (0.1-3 parts). This parameter change in material composition provides both secure attachment and antibacterial protection, resolving the contradiction between attachment security and harm prevention.
Solution Approach 2:
The adhesive layer uses a composite material system combining multiple components (SIS copolymer, propylene glycol, polyisobutene, CMC, silica, and zeolite) that work synergistically. The zeolite and silica provide antibacterial properties while the polymer matrix ensures secure adhesion, thus achieving both reliable attachment and protection against nail damage and infection.
2Object-affected harmful factors
If disposable nail tips are used, then hygiene concerns are reduced, but environmental waste increases and cost accumulates
Solution Approach 1:
The nail tip is designed to be reusable rather than disposable. The adhesive layer can be removed without damaging the natural nail, allowing the nail tip to be cleaned and reused multiple times. This recovers the value of the nail tip product while reducing waste, and the antibacterial adhesive composition maintains hygiene standards across multiple uses.
Solution Approach 2:
The nail tip system provides self-service hygiene protection through the antibacterial properties of the adhesive layer containing zeolite and silica. The material inherently resists bacterial growth, maintaining hygiene without requiring external disinfection processes, enabling safe reuse over time.
3Productivity
If traditional adhesive methods are used, then nail tips can be attached quickly, but side effects and nail injury may occur
Solution Approach 1:
The adhesive composition parameters are optimized to achieve rapid setting while maintaining safety. The specific ratios of SIS copolymer, propylene glycol, and other components enable quick adhesion formation without the harsh chemicals that cause nail damage, thus achieving both fast attachment and minimal side effects.
Solution Approach 2:
The adhesive formulation converts potentially harmful conventional adhesive properties into beneficial ones. Instead of using strong solvents or harsh chemicals for quick setting, the patent uses a water-based or gentler solvent system with polymers that provide rapid adhesion without nail damage, turning the need for fast setting into an opportunity to use safer materials.
