Solution Overview
Problem
Conventional ink compositions fail to effectively provide a satisfying metal sense visual effect without using high-priced metallic pigments, leading to increased ink weight and precipitation issues, and limited functionality in expressing diverse visual effects.
Innovation Solution
A recrystallization type ink composition using a solvent and urea as a crystalline material, with a colorant, which recrystallizes on non-absorption surfaces like whiteboards or glass, eliminating the need for metallic pigments and enhancing visual effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If metallic pigment is used to provide metal sense visual effect, then the visual effect is improved, but the manufacturing cost increases
Solution Approach 1:
The patent changes the physical state parameter of urea from solid crystal to dissolved state in solvent, then back to crystal upon evaporation. This parameter change enables the urea to form recrystallized structures that mimic metallic visual effects without using expensive metallic pigments, thus resolving the contradiction between manufacturing cost and visual effect quality
Solution Approach 2:
The patent utilizes the phase transition of urea between dissolved and crystallized states. When the solvent evaporates, the dissolved urea recrystallizes forming needle-like or plate-like crystal structures that reflect light similarly to metallic surfaces. This phase transition mechanism provides the metal sense visual effect at low manufacturing cost
2Object-generated harmful factors
If inorganic pigment coated with high specific gravity material is used, then the metal sense visual effect is improved, but the ink composition weight increases and precipitation occurs
Solution Approach 1:
The patent replaces heavy, expensive inorganic pigments with a lightweight organic compound (urea) that achieves similar visual effects through recrystallization. The urea-based ink composition is lightweight, does not precipitate during storage, and provides satisfactory metal sense visual effects, thus resolving the contradiction between visual effect quality and ink composition weight
Solution Approach 2:
The patent creates a composite system where urea crystals are formed within the ink composition matrix after solvent evaporation. The recrystallized urea structures embedded in the dried ink residue provide the metal sense visual effect without the weight and precipitation problems of traditional heavy inorganic pigments
3Stability of the object's composition
If conventional ink composition is used, then the color stability is maintained, but the visual effect diversity is limited
Solution Approach 1:
The patent introduces dynamic visual effects into the ink composition by utilizing the recrystallization process. The ink transitions from a uniform dissolved state during application to a crystallized state with varied light reflection patterns after drying. This dynamic transformation provides diverse visual effects (metallic, sparkling, textured) while maintaining color stability, resolving the contradiction between color stability and visual effect diversity

AI summary
A recrystallization type of ink composition comprises a solvent, a crystalline material, and a colorant. When the recrystallization type of ink composition is applied to a non-absorption surface such as a whiteboard, a glass surface, and a plastic surface, it is recrystallized to provide a visual effect of a metal sense at the applied part.
