Cosmetic Laser Printer Solving Toner Transfer Contradiction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for applying personalized makeup to human keratin materials, such as skin, lips, and hair, lack the ability to produce complex patterns efficiently and safely, as they often require solvents and are not precise enough.
Innovation Solution
A laser printer configured for electrophotography or magnetophotography is used to deposit cosmetic toner onto a support, which can then be transferred to keratin materials without a fuser, allowing for precise and personalized pattern application, including complex designs, without the need for solvents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fuser is used to fix the toner onto the support, then the toner adhesion is improved, but the toner can no longer be removed or transferred to keratin materials
Solution Approach 1:
The patent removes the fuser component from the laser printer system entirely, extracting the harmful element that caused the toner to become permanently fixed. This allows the toner to remain in a transferable state while still being deposited onto the support through the electrophotographic process, resolving the contradiction between adhesion and transferability.
Solution Approach 2:
The patent applies a preliminary adhesive layer to the support before toner deposition. This preliminary action provides the necessary adhesion for the toner to stick to the support during handling, while the absence of a fuser ensures the toner remains removable and transferable to keratin materials when needed.
2Ease of operation
If conventional inkjet printing is used to deposit cosmetic composition, then direct application is achieved, but complex patterns cannot be produced with sufficient precision
Solution Approach 1:
The patent introduces an intermediary support element that receives the high-precision laser-printed pattern and then transfers it to the keratin materials. This intermediary allows the system to combine the precision of laser printing with the ease of direct application, as the support can be directly contacted with the skin or hair surface.
Solution Approach 2:
The patent creates a precise copy of the desired pattern on the support through laser printing, which is then transferred to the keratin materials. This copying process allows complex patterns to be produced with high precision before being applied directly to the target surface, combining precision manufacturing with ease of application.
3Manufacturing precision
If multiple toner cartridges are used to print complex patterns, then pattern complexity and resolution are improved, but device complexity increases
Solution Approach 1:
The patent makes the laser printer universally compatible with standard cosmetic toner cartridges, allowing the use of existing multi-color cartridge systems. This universality enables complex, high-resolution patterns to be printed using conventional cartridge configurations without requiring custom or specialized printer modifications, thus avoiding increased device complexity.
4Adaptability or versatility
If the printer is configured to recognize and deactivate the fuser for cosmetic toner, then compatibility with cosmetic use is improved, but conventional printing functionality is reduced
Solution Approach 1:
The patent implements a dynamic fuser configuration that can be activated or deactivated based on the detected toner type. When cosmetic toner is detected, the fuser is deactivated to allow transferability; when conventional toner is used, the fuser remains active for standard printing. This dynamic adaptation maintains both cosmetic application compatibility and conventional printing productivity without sacrificing either function.
