Applicator With Adjustable Storage And Flexible Absorbing Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic and dyeing applicators face challenges in handling liquids of varying viscosities and materials, leading to issues with liquid leakage and inconsistent application, as well as high manufacturing costs due to the need for multiple molds and shapes to accommodate different viscosities and amounts of accumulation.
Innovation Solution
The development of an applicator with a cylindrical body, a core-like application member, a storage, and a liquid applying material absorbing body, where the absorbing body is made of a flexible foam material with an open cell structure, allowing for adjustable length and compression to accommodate different viscosities and materials, and a plug system that adjusts the storage region to prevent liquid leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the absorbing body is made with a resin molded product with an uneven surface in an accordion shape to adjust the amount of output, then the amount of liquid applying material delivered to the core material can be adjusted, but the manufacturing cost increases due to high mold requirements
Solution Approach 1:
The patent changes the material parameter from rigid resin to flexible foam, allowing the absorbing body to be made from a single uniform material that can be easily molded. The flexibility parameter of the foam allows it to conform to different shapes and sizes without requiring complex molds, thereby reducing manufacturing cost while maintaining the ability to control liquid output through simple dimensional adjustments
Solution Approach 2:
The flexible foam absorbing body serves multiple functions: it absorbs liquid applying material, controls the amount of output, and can be easily manufactured in various sizes. This universal component replaces the need for specialized resin molded products with complex accordion shapes, achieving the same liquid control function with a simpler, more cost-effective solution
2Adaptability or versatility
If the storage region size is changed to adjust the amount of accumulation for different liquid applying materials, then the applicator can handle different materials, but the applicator size and shape must be changed, increasing manufacturing cost
Solution Approach 1:
The patent introduces a movable partition that can be positioned at different locations within the storage region, dynamically adjusting the storage capacity for different liquid applying materials. This dynamic adjustment mechanism allows a single applicator body to handle various material volumes without requiring multiple fixed-size applicators, thereby maintaining versatility while reducing manufacturing costs through standardization
Solution Approach 2:
The storage region is segmented by a movable partition that can be repositioned to create different storage volumes. This segmentation allows the same applicator body to be configured for different liquid applying material amounts, providing adaptability without requiring multiple different applicator sizes or shapes
3Duration of action of moving object
If the applicator is used in parallel state or with rear end side lowered to maintain liquid application, then the application can continue, but the impregnation of bulk liquid from storage to core material is not adjusted well, causing inconsistent output
Solution Approach 1:
The flexible foam absorbing body provides continuous feedback on the liquid level in the storage region. As the liquid level changes during use, the foam's absorption and release characteristics automatically adjust to maintain consistent liquid delivery to the core material, ensuring stable output throughout the application duration regardless of the applicator's orientation or usage pattern
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 applicator ensures consistent application across various liquid viscosities and materials without leakage, reduces manufacturing costs by using a standard size and shape, and maintains efficient impregnation even when the liquid level decreases, allowing for dual-use functionality.
Implementation Method 1
an application member made of a core material made of a fiber member or a similar member to absorb and infiltrate the liquid applying material
Implementation Method 2
the absorbing body is made of a flexible foam material with an open cell structure

AI summary
An applicator includes a body, an application member, a storage for a liquid applying material, a liquid applying material absorbing body configured to adjust an amount of impregnation, and a first plug configured to cause a rear end side of the application member to be inserted through an insertion hole to hold the application member. The first plug is configured to expose the rear end side of the application member to a side of the storage. A storage region is configured to be increased and decreased by changing a position of a second plug. The absorbing body is mounted to a distal end and is cuttable.
