Pressed Powder Layering for Unbroken Printed Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressed powder products suffer from simple, single-colored patterns that are easily broken and lack integrity, which affects their aesthetic appeal and sales volume.
Innovation Solution
A pressed powder product with an unbroken pattern is achieved by incorporating an ink absorbing layer composed of hydroxyapatite and kaolin particles, along with a color developing agent and stabilizer, to prevent ink permeation and enhance pattern integrity, using a method that includes spraying a mixture of these components onto a pressed powder layer and drying it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a pattern is disposed on the pressed powder surface by spraying white slurry, then the pressed powder has some decorative pattern, but the pattern is simple, single-colored, and may be broken
Solution Approach 1:
The pressed powder product is divided into multiple functional layers: pressed powder layer, ink-absorbing layer, and pattern layer. This segmentation allows each layer to perform its specific function - the ink-absorbing layer prevents ink penetration while the pattern layer provides the decorative pattern, thereby improving pattern integrity without compromising product complexity
Solution Approach 2:
An ink-absorbing layer is introduced as an intermediary between the pressed powder layer and the pattern layer. This intermediate layer absorbs excess ink and prevents it from penetrating into the pressed powder, thereby maintaining pattern integrity and preventing pattern breakage
2Shape
If ink is printed directly on the pressed powder surface, then the pattern can be formed, but the ink permeates into the pressed powder product causing pattern breakage
Solution Approach 1:
The ink-absorbing layer serves as a mediator between the ink and the pressed powder. It captures and retains the ink within its structure, preventing the ink from permeating into the pressed powder and causing pattern breakage, thereby maintaining pattern integrity
Solution Approach 2:
The ink-absorbing layer utilizes porous materials that can absorb and retain ink within their pore structures. This porous structure allows the layer to take up ink without allowing it to penetrate through to the pressed powder, thus preventing pattern breakage while maintaining pattern integrity
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
The solution results in a pressed powder product with improved pattern integrity and reduced ink permeation, maintaining aesthetic quality and enhancing consumer appeal.
Implementation Method 1
an ink absorbing layer, and a pattern layer. The pattern layer is prepared by printing with an ink. The ink absorbing layer is formed by spraying an ink-absorbing paint on the pressed powder layer
Implementation Method 2
The ink-absorbing paint includes 0.5% to 10% by weight of an oil controlling agent, 0.5% to 20% by weight of a color developing agent, 55% to 98.5% by weight of solvent, and 0.5% to 10% by weight of a stabilizer

AI summary
A pressed powder product and a method for preparing the same are provided. The pressed powder product includes a pressed powder layer, an ink absorbing layer and a pattern layer. The pattern layer is obtained by printing. The ink absorbing layer is formed by spraying an ink-absorbing paint on the pressed powder layer. The ink-absorbing paint includes 0.5% to 10% by weight of an oil controlling agent, 0.5% to 20% by weight of a color developing agent, 55% to 98.5% by weight of a solvent, and 0.5% to 10% by weight of a stabilizer. The method for preparing the pressed powder product includes: uniformly mixing an oil controlling agent, a color developing agent, a solvent, and a stabilizer to obtain the mixture; spraying the mixture on a pressed powder layer, and drying to obtain a semi-manufactured pressed powder product; and, printing a pattern on the semi-manufactured pressed powder product.
