Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic products struggle to apply different topical compositions to various skin zones efficiently without mixing, and they often require high amounts of polyols or oils that cannot be completely dried, limiting their sensory experience.
Innovation Solution
A system and method using pressured gas to apply two fluid cosmetic formulas and a binder onto targeted areas of a substrate, allowing for efficient and precise application of sufficient quantities without mixing, using a conveyor and applicators with valves controlled by a controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional depiction techniques (lithography, screen printing, ink jet printing) are used to apply cosmetic formulas on substrates, then the formulas can be applied on targeted zones, but the quantity of formula deposition is insufficient
Solution Approach 1:
The patent employs a pneumatic spray system where compressed gas flows through a nozzle to atomize and deposit cosmetic formula onto the substrate. This hydraulic/pneumatic mechanism enables sufficient quantity deposition while maintaining targeted zone application, resolving the limitation of conventional depiction techniques that cannot achieve both adequate quantity and precision.
2Stability of the object's composition
If different cosmetic compositions are applied on a substrate in a dry stage, then mixing of formulas can be prevented, but high amounts of polyols or oils cannot be used since they cannot completely dry
Solution Approach 1:
The patent applies a hydrophobic coating to the substrate before applying the cosmetic formulas. This preliminary action creates a barrier that prevents mixing of different formulas while allowing the use of compositions containing polyols and oils that cannot completely dry, thus resolving the contradiction between preventing mixing and maintaining composition flexibility.
3Ease of operation
If a single product comprises multiple cosmetic compositions for targeted zones, then users do not need to handle several distinct products, but the system must apply sufficient quantities of different formulas without mixing
Solution Approach 1:
The patent divides the substrate into multiple targeted zones with different hydrophobic properties, allowing different cosmetic formulas to be applied to each zone. The hydrophobic segmentation prevents mixing between zones while enabling a single product to deliver multiple compositions, thus resolving the contradiction between user convenience and manufacturing precision.
4Productivity
If pressed gas is used to apply liquid cosmetic formulas on substrate, then sufficient quantities can be applied efficiently, but discrete regions must be created to avoid mixing of different formulas
Solution Approach 1:
The patent creates discrete regions on the substrate with different hydrophobic qualities (hydrophobic vs. hydrophilic zones). This local quality differentiation allows efficient pneumatic application of multiple formulas while preventing mixing through the inherent hydrophobic barrier, thus resolving the contradiction between productivity and device complexity.
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 system enables the efficient application of sufficient amounts of cosmetic formulas onto individual targeted areas of a substrate, preventing mixing and allowing for a sensory experience similar to packed masks, with the option to be used immediately or packed without mixing.
Implementation Method 1
a pressured gas supply unit (20) which is fluidly connected to the first to third storage tanks (10a to 10c) and is configured to be capable of causing a pressure of the pressured gas to act on the first to third liquids (F1 to F3) within the first to third storage tanks (10a to 10c)
Implementation Method 2
a third liquid (F3), which is a binder, is applied toward a boundary area between a targeted area for the first liquid (F1) and a targeted area for the second liquid (F2) on the substrate (S) by the action of the pressured gas from the pressured gas supply unit (20), wherein the binder is configured to be capable of preventing mixing of the first and second liquids (F1 and F2) after application

AI summary
The present invention relates to a system (1) for applying at least two kinds of liquid onto respective targeted areas of a substrate (S). The system (1) includes first and second storage unit (10a, 10b) that accommodate first and second liquids (F1, F2); a pressured gas supply unit (20) that is fluidly connected to the first and second storage unit (10a, 10b); first and second applicator (30a, 30b) that are fluidly connected to the first and second storage unit (10a, 10b); and a controller (40) that is operatively connected to the applicator (30a, 30b). The pressured gas supply unit (20) causes pressure of a pressured gas to act on the liquids (F1, F2) within the storage unit (10a, 10b). The first and second applicator (30a, 30b) each include at least one nozzle (300a, 300b) disposed so as to face the substrate (S). The first and second applicator (30a, 30b) spray the first and second liquids (F1, F2) within the first and second storage unit (10a, 10b) from the nozzles (300a, 300b) toward the substrate (S) by the action of the pressured gas from the pressured gas supply unit (20). The controller (40) individually controls the first and second applicator (30a, 30b) so that the first applicator (30a) sprays the first liquid (F1) toward a targeted area for the first liquid (F1) on the substrate (S) and the second applicator (30b) sprays the second liquid (F2) toward a targeted area for the second liquid (F2) on the substrate (S). The present invention also relates to a method for applying at least two kinds of liquid onto respective targeted areas of a substrate (S).
