Multi-Color Adhesive System for Precise Color Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adhesive systems face challenges in producing adhesives with a wide color spectrum, particularly in achieving precisely defined and reproducible colors, especially for shades of gray and beige, due to rapid solidification and high dye concentrations, which limits their application in materials like plastics, stones, and ceramics.
Innovation Solution
A multi-color component adhesive system comprising at least two miscible polymerizable components, with one component being colorless and the others containing different coloring agents, along with a separate hardener component, allowing for the creation of a polymerizable mixture of any color. This system includes thixotropic agents for consistent application and UV stabilizers to prevent yellowing, enabling precise color matching and reproducibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional adhesive systems use high concentration dye pastes for coloring, then color intensity is achieved, but manufacturing precision of defined and reproducible colors deteriorates
Solution Approach 1:
The patent changes the concentration parameter of coloring agents from high (conventional paste form) to low (0.01-10% by weight range), and introduces multiple coloring agents with different colors that can be mixed in varying proportions. This parameter change enables precise color definition and reproducibility while maintaining sufficient color intensity through the synergistic effect of multiple dyes.
Solution Approach 2:
The patent segments the coloring function into multiple separate coloring agents (different colors) that are distributed across different polymerizable components. Instead of using a single high-concentration dye paste, the system uses multiple low-concentration coloring agents that can be independently adjusted and mixed to achieve precise color matching and reproducibility.
2Manufacturing precision
If pre-colored adhesives are prepared in advance for different materials, then color matching is achieved, but adaptability deteriorates due to rapid solidification preventing mixing of different colors
Solution Approach 1:
The patent introduces dynamics into the color matching process by providing separate polymerizable components with different coloring agents that remain liquid and mixable until the moment of use. The system transitions from static pre-colored adhesives to a dynamic mixing system where colors can be adjusted and combined on-demand, enabling both precise color matching and high adaptability through rapid mixing before polymerization.
Solution Approach 2:
The patent applies preliminary action by pre-preparing multiple polymerizable components with different coloring agents in liquid form, but delays the color mixing until the moment of application. This allows the system to maintain color stability during storage while enabling flexible color customization during use, resolving the contradiction between color matching precision and adaptability.
3Adaptability or versatility
If multiple polymerizable components with different coloring agents are mixed, then color spectrum and adaptability are improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a unified system: the same polymerizable components that provide adhesive functionality also carry coloring agents. Instead of separate adhesive and coloring systems, the invention combines these functions, allowing color variety to be achieved through simple mixing of components that already serve dual purposes, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent applies universality by designing polymerizable components that serve multiple functions: they act as both the adhesive base and the coloring medium. Each component contains both polymerizable compounds and coloring agents, allowing the same system to provide both bonding and coloration functions, thus achieving wide color spectrum without proportionally increasing system complexity.
