Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic batching devices are unsuitable for personal use due to their large size, weight, cost, and the issue of volatile components causing chemical smells and product drying due to air contact, making them impractical for home use, especially when producing customized nail enamels.
Innovation Solution
A portable, automatic batching device with improved cartridges featuring a flexible container made of elastic plastic material to prevent air contact and a delivery system with a sealed delivery head that allows controlled dispensing and batching of cosmetic products, ensuring the product remains usable and prevents volatile component dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If industrial dye-meters are used for batching cosmetic components, then batching precision and component delivery accuracy are improved, but device size, weight, and cost increase significantly making them unsuitable for personal use
Solution Approach 1:
The system divides the batching function into separate cartridges, each containing a specific cosmetic component. This modular approach allows the main device to remain compact while achieving precise batching through the specialized cartridges that hold pre-measured or dispensable amounts of each component.
Solution Approach 2:
The cartridge acts as an intermediary between the cosmetic components and the batching device. It contains the components in a controlled environment and interfaces with the delivery system, enabling precise dispensing without requiring the main device to store and manage all components directly, thus reducing device size and weight.
2Ease of operation
If cosmetic components are stored in open cartridges, then accessibility and ease of dispensing are improved, but the products quickly deteriorate due to air contact causing them to become viscous or dry
Solution Approach 1:
The cartridge employs a flexible container made of elastic plastic material that forms a sealed environment around the cosmetic product. This flexible shell maintains product stability by preventing air contact while allowing the cartridge to be easily inserted and removed from the batching device for dispensing.
Solution Approach 2:
The sealed cartridge serves as an intermediary that protects the cosmetic product from environmental degradation. It maintains the product in a stable, usable state during storage and transport, only opening or dispensing when needed, thus bridging the gap between storage stability and operational accessibility.
3Ease of operation
If volatile cosmetic components are mixed in open environments, then mixing visibility and control are improved, but chemical smells disperse into the surrounding environment creating harmful factors
Solution Approach 1:
The system uses sealed cartridges that create an inert environment for the volatile cosmetic components. The flexible plastic container acts as a barrier that contains the volatile components, preventing their dispersion into the surrounding environment while still allowing the batching device to access and dispense the components for mixing.
Solution Approach 2:
The sealed cartridge functions as an intermediary that isolates the volatile components from the external environment. It allows controlled access to the components for batching and mixing operations while preventing the harmful dispersion of chemical smells, thus mediating between operational needs and environmental protection.
4Reliability
If a sealed flexible container is used in the cartridge, then product protection from air contact is improved, but device complexity increases due to additional sealing mechanisms
Solution Approach 1:
The flexible container made of elastic plastic material provides an effective sealing mechanism that is integrated into the cartridge structure. This flexible shell simplifies the overall sealing system by combining the containment and sealing functions in a single component, reducing the need for separate complex sealing mechanisms while maintaining product protection.
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 device is compact, lightweight, and effectively prevents the dispersion of volatile components, ensuring the stability and usability of cosmetic products, allowing for safe and efficient production of customized cosmetics, such as nail enamels, at home.
Implementation Method 1
at least one flexible container (5) made as a bag made of a suitably elastic plastic material, so that the compound itself is not in contact with air
Implementation Method 2
a delivery head (9) having a rest position, (like the one, for example, shown in Figure 1) in which such delivery head (9) keeps such delivery duct (7) closed and air-tightly insulates the dyeing component contained inside the flexible container (5)
