Innovation Solution
A paint composition comprising epoxy or acrylic water-based varnish, catalyst, and additive, combined with an automated and parameterized method controlling preheating, surface temperature, paint spraying angle, and curing temperature, ensures full adherence and polymerization on the flask's inner surface, creating a thin layer that does not interfere with packaged products, and allows for three-dimensional visual effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional painting methods are used, then the painting process is simple, but unique and sophisticated visual effects cannot be achieved
Solution Approach 1:
The patent applies parameter changes by precisely controlling multiple process parameters including preheating temperature (60-80°C), surface temperature (20-40°C), paint spraying angle (30-60°), and curing temperature (100-200°C). These parameter optimizations enable the creation of unique visual effects while maintaining a manageable painting process through automated control.
2Adaptability or versatility
If paint is applied to the inside of vitreous flasks, then distinctive packaging is achieved, but the paint may interfere with the packaged product
Solution Approach 1:
The patent applies local quality by creating a thin paint layer specifically on the inner surface of the flask that provides distinctive visual effects while maintaining product compatibility. The controlled application ensures the paint is localized to the surface where it serves its aesthetic function without compromising the inert properties of glass or interfering with packaged products.
Solution Approach 2:
The patent uses water-based paint composition that forms a thin, non-interfering layer on the glass surface. This approach allows for distinctive packaging without requiring expensive specialized coatings, and the thin layer ensures it does not interfere with product storage while still achieving the desired visual effect.
3Manufacturing precision
If automated and parameterized method is used, then painting precision and customization are improved, but process complexity increases
Solution Approach 1:
The patent implements feedback control by monitoring and adjusting the preheating temperature, surface temperature, and curing temperature during the painting process. This feedback mechanism ensures precise control over paint application and curing, achieving consistent visual effects and proper adhesion while managing process complexity through automated temperature regulation.
