Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gel nails are used to cover natural nails, then the application process is simplified, but the viscosity and density are low making them easily damaged and difficult to handle
Solution Approach 1:
The patent uses a composite material consisting of a polymer adhesive combined with inorganic filler particles (such as silica, glass beads, or metal oxides) to create a nail covering composition that exhibits both high viscosity/density for strength and ease of application. The filler particles reinforce the polymer matrix, providing structural integrity while maintaining workability during application.
2Ease of operation
If gels are used for nail covering, then application is easier, but polishing capacity is low and handling is difficult
Solution Approach 1:
The patent modifies the physical and chemical parameters of the gel composition by adjusting the polymer chain length, crosslinking density, and filler particle size distribution to optimize both application ease and polishing capacity. The composition is formulated to achieve a balance between softness for application and hardness for polishing resistance.
3Ease of operation
If gels are used for nail covering, then application is simplified, but density is non-homogeneous requiring additional painting
Solution Approach 1:
The patent ensures homogeneous distribution of filler particles throughout the polymer adhesive matrix through controlled mixing processes and appropriate rheological modification. The composition is formulated to prevent sedimentation and aggregation of filler particles, maintaining uniform density and color throughout the product for consistent aesthetic results without requiring additional painting.
4Ease of operation
If gels are used for nail covering, then application is easier, but skin absorption rate is high
Solution Approach 1:
The patent introduces a barrier layer or modifying agent between the gel composition and the natural nail to reduce direct contact and absorption. The polymer adhesive is formulated with molecules that have low affinity for nail keratin, or a primer layer is applied that prevents penetration of gel components into the natural nail, thereby reducing skin absorption while maintaining application ease.
5Ease of operation
If gels are used for nail covering, then application is simplified, but drying time is long requiring 5 minutes
Solution Approach 1:
The patent replaces the traditional air-drying or evaporation-based drying mechanism with a photopolymerization or chemical crosslinking system that rapidly sets the gel composition. UV or LED light curing initiates polymerization reactions that transform the liquid gel into a solid coating in seconds, eliminating the 5-minute air-drying wait time while maintaining ease of application.
6Strength
If acrylics are used for nail covering, then structural strength is improved, but chemical polymerisation requires mixing two components generating air bubbles and porosities
Solution Approach 1:
The patent combines the monomer and polymer components into a single pre-mixed formulation or uses a one-component system that cures through moisture from the air or a single initiator system. This eliminates the need for separate mixing of two components, preventing air bubble incorporation while maintaining the structural strength benefits of acrylic-based materials.
7Strength
If acrylics are used for nail covering, then structural strength is improved, but strong chemical smell is generated during application and removal
Solution Approach 1:
The patent uses acrylic components with low volatility and low odor formulations, or encapsulates the reactive components in a matrix that releases them slowly during curing. The removal process uses buffered acetone or alternative solvents that reduce the strength and odor of chemicals involved, maintaining structural strength while minimizing harmful chemical smells during application and removal.
8Stability of the object's composition
If gel nails requiring UV exposure are used, then hardening is achieved, but prolonged UV exposure causes skin burns
Solution Approach 1:
The patent uses LED lights that emit at specific wavelengths matched to the photoinitiator absorption peak, providing high-intensity curing in brief periodic pulses rather than prolonged UV exposure. The curing process is optimized to achieve complete hardening in 5-10 seconds of LED exposure, dramatically reducing total energy exposure to the skin while maintaining effective polymerization.
9Ease of operation
If resin lacking filler particles is used, then application is simplified, but contraction during polymerisation is high and resistance to fracturing is low
Solution Approach 1:
The patent incorporates inorganic filler particles (such as silica, glass beads, alumina, or metal oxides) into the resin matrix to create a composite material that reduces polymerization shrinkage and enhances fracture resistance. The filler particles act as spacers that maintain volume stability during curing and provide reinforcement that prevents cracking and chipping, while the resin continues to provide ease of application.
