Solution Overview
Problem
Existing applicators for applying UV nail polish and UV gel in nail studios are prone to contamination and pose health risks due to solvent inhalation, and they lack efficiency and adaptability for uniform application on curved nail surfaces.
Innovation Solution
A cylindrical applicator with a housing divided into sections, featuring an applicator head, a reservoir container with a piston, and an electrical gear motor-driven advancing mechanism, allowing for controlled and adjustable application of liquid media through a cross-opening tip, reducing contamination and health risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple brush-type applicator is used for applying UV gel or UV nail polish, then the device complexity is low and ease of manufacture is high, but contamination of the workplace increases and health risks from solvent inhalation worsen
Solution Approach 1:
The applicator is divided into separate functional sections: a reservoir container for holding the liquid medium, a piston for controlling dispensing, an applicator head for application, and an electrical gear motor for automation. This segmentation allows each component to perform its specific function while isolating the liquid medium from direct exposure, reducing contamination and health risks.
Solution Approach 2:
The piston acts as an intermediary mechanism between the reservoir container and the applicator head. It controls the dispensing of the liquid medium in a controlled manner, preventing direct exposure of the user to solvents and reducing workplace contamination while maintaining ease of operation.
2Device complexity
If a simple brush-type applicator is used, then the device complexity is low, but the uniformity of application on curved nail surfaces deteriorates and complete coverage becomes difficult
Solution Approach 1:
The applicator head is designed to be dynamic and adaptable, allowing it to conform to the curved surface of the nail. The controlled dispensing mechanism enables precise application of the liquid medium, ensuring uniform coverage across the nail surface while maintaining a relatively simple overall device structure.
3Ease of operation
If a controlled dispensing mechanism with piston and electrical motor is implemented, then application control and uniformity improve, but device complexity increases
Solution Approach 1:
The electrical gear motor automatically drives the piston to dispense the liquid medium, eliminating the need for manual operation of the dispensing mechanism. This self-service approach improves application control and uniformity while keeping the overall device structure relatively simple and easy to operate.
4Object-affected harmful factors
If a closed reservoir container system is used, then contamination and solvent inhalation risks are reduced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The reservoir container is designed as a separate, self-contained unit with integrated piston and dispensing mechanisms. This segmentation allows for modular manufacturing, where each component can be produced independently using standard manufacturing processes, reducing overall manufacturing complexity while maintaining a closed system that prevents solvent inhalation and contamination.
