Spray Nail Polish Composition for Precision Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fingernail polish application methods require manual dexterity and accuracy to avoid smears on cuticles and skin, leading to laborious removal and extended application time, with existing solutions not fully addressing these issues.
Innovation Solution
A decorative nail polish composition applied using a spray cylinder with a high solvent content and minimal fixative, allowing quick application without precision, with the solvent dissolving and fixing the polish only on the nail surface, and easy removal from skin with soap and water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional brush application of coloured polish is used, then precision and control over polish placement is improved, but application time and manual dexterity requirements increase
Solution Approach 1:
The patent replaces the mechanical brush application system with a spray application system. The spray device delivers polish as a fine aerosol mist that automatically distributes evenly across the nail surface without requiring manual dexterity or precision control, thereby reducing application time while maintaining uniform coverage.
Solution Approach 2:
The patent changes the physical state and delivery parameters of the polish from a viscous liquid applied via brush to an aerosolized fine mist. This parameter change allows the polish to be applied quickly and uniformly without the precision requirements of brush work, resolving the contradiction between precision and application time.
2Reliability
If solvent is used to remove accidentally coloured skin and cuticles, then complete removal of polish is achieved, but the process becomes more laborious and time-consuming
Solution Approach 1:
The patent extracts the harmful effect by formulating the polish to be specifically soluble in water rather than requiring strong solvents like acetone. This allows accidental polish on skin to be easily removed with simple water and soap, eliminating the need for laborious solvent-based removal while maintaining complete removal capability.
Solution Approach 2:
The patent changes the solubility parameter of the polish formulation to be water-soluble. This parameter change transforms the removal process from requiring strong chemical solvents to simple water and soap, making the removal process easier and less time-consuming while still achieving complete removal.
3Reliability
If transparent polish base layer is applied followed by coloured layer, then nail reinforcement and regeneration are improved, but application complexity and time increase
Solution Approach 1:
The patent merges the transparent base layer and coloured decorative layer into a single integrated polish formulation. This combined formulation maintains the nail reinforcement benefits of a base layer while adding decorative colour in one application, eliminating the need for separate sequential applications and reducing overall complexity.
Solution Approach 2:
The patent creates a universal polish formulation that simultaneously provides nail reinforcement, regeneration, and decorative colouring in a single product. This multi-functional formulation eliminates the need for separate base and coloured layer applications, simplifying the overall process while maintaining all desired benefits.
4Ease of manufacture
If acrylic paint spraying method is used, then decorative effect is improved, but drying time and process complexity increase
Solution Approach 1:
The patent changes the chemical composition parameters of the decorative polish to use fast-drying solvents and film-forming agents. This parameter change allows the sprayed decorative layer to dry quickly after application, reducing the waiting time while maintaining the desired decorative acrylic paint effect.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces application time, eliminates smears, and simplifies the process, making it faster and more practical while maintaining a smooth, streak-free finish.
Implementation Method 1
a) at least one solvent, in a percentage of 75 to 90%, to dissolve the fixatives of the polish base
Implementation Method 2
b) a fixative, in a percentage of 0.5 to 3%, to fix the decorative polish applied on the polish base
