Bio-based Nail Tips with Microscale Texture for Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nail tips are often made from non-renewable materials like ABS plastic, leading to environmental concerns and health issues due to microplastic accumulation, and they can be uncomfortable or damaging if poorly fitted, lacking customization to match natural nail curvature.
Innovation Solution
A bio-based, customizable nail tip system using plant-based resin/plastic with microscale and millimeter-scale textures for better adhesion and a UV-curable soy-based plastic, allowing for 3D printing and customization to match individual nail shapes, along with a plant-based adhesive and stickers for improved fit and sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional ABS plastic is used for nail tips, then manufacturing cost is low and ease of manufacture is high, but environmental harm increases due to microplastic accumulation and non-renewability
Solution Approach 1:
The patent changes the material parameter from traditional ABS plastic to plant-based resin/plastic, transforming the chemical composition to be renewable and biodegradable. This parameter change eliminates microplastic accumulation while maintaining the nail tip's structural integrity and manufacturability through standard molding processes.
Solution Approach 2:
The patent employs composite material structures by combining plant-based resin with specific surface textures (microscale and millimeter-scale features) to create a multi-functional material system that provides both environmental sustainability and enhanced adhesion properties.
2Reliability
If standard plastic nail tips are used, then production is simple and productivity is high, but reliability decreases due to poor fit and potential damage to natural nails
Solution Approach 1:
The patent applies local quality by incorporating specific surface textures at different scales (microscale ridges and millimeter-scale patterns) only on the bottom surface of the nail tip. This localized texturing improves adhesion and fit to the natural nail plate without complicating the overall production process or requiring additional manufacturing steps.
Solution Approach 2:
The patent implements preliminary action by pre-forming the customized contour and surface textures during the initial molding process. This allows the nail tips to be ready for application with optimal fit and adhesion characteristics already built-in, eliminating the need for post-production customization or adjustment steps.
3Stability of the object's composition
If plant-based resin is used instead of ABS plastic, then environmental sustainability improves, but material strength and durability may be compromised
Solution Approach 1:
The patent changes the material parameter to plant-based resin while optimizing its mechanical properties through formulation adjustments. The resulting material achieves sufficient strength and durability for nail tip application while maintaining renewable and biodegradable characteristics, resolving the contradiction between environmental sustainability and material strength.
4Reliability
If nail tips lack surface textures, then manufacturing is simpler, but adhesion to natural nail and coating application are poor
Solution Approach 1:
The patent applies local quality by incorporating specific surface textures at different scales (microscale ridges and millimeter-scale patterns) only on the bottom surface of the nail tip. This localized texturing improves adhesion and fit to the natural nail plate without complicating the overall production process or requiring additional manufacturing steps.
Solution Approach 2:
The patent implements preliminary action by pre-forming the customized contour and surface textures during the initial molding process. This allows the nail tips to be ready for application with optimal fit and adhesion characteristics already built-in, eliminating the need for post-production customization or adjustment steps.
