Press-Button Makeup Pen Mechanism for One-Handed Cosmetic Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetics such as lipsticks and eyeliners require two-handed operation for discharge due to their rotating mechanism, which is inconvenient and can lead to material waste and pollution.
Innovation Solution
A press-type makeup pen with a drive assembly featuring a button that allows single-handed unidirectional discharge, utilizing a nib assembly, body assembly, discharge assembly, and drive assembly components including a sleeve, material loading member, and threaded rod for convenient loading and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotating mechanism is used for cosmetic discharge, then the cosmetic can be discharged from the container, but two-handed operation is required which reduces convenience
Solution Approach 1:
The patent replaces the traditional rotating mechanical system with a pressing mechanism. Instead of rotating the base or rotating portion to discharge cosmetic, the user simply presses the tail portion, which actuates a pressing member that moves the cosmetic outward through a pressing hole. This substitution of mechanical principle eliminates the need for two-handed rotation operation while achieving cosmetic discharge.
2Loss of substance
If rotation is required to discharge cosmetic, then the cosmetic reaches out of the container, but material waste and pollution occur due to difficult control
Solution Approach 1:
The pressing mechanism allows for controlled, incremental discharge of cosmetic material. Each press action dispenses a precise, limited amount of cosmetic through the pressing hole, preventing excessive discharge. The user can control the quantity by the number and force of presses, thereby reducing material waste and pollution compared to rotation mechanisms that may dispense uncontrolled amounts.
3Ease of operation
If a pressing mechanism is used for single-handed operation, then convenience is improved, but the structure becomes more complex
Solution Approach 1:
The drive assembly is segmented into distinct functional components: a pressing member that directly contacts and moves the cosmetic, a tail portion that transmits user pressure, and a connection structure linking these elements. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural simplicity suitable for single-handed operation.
Solution Approach 2:
Instead of having the user rotate the container body or base, the design inverts the operation by having the user press the tail portion which then moves the cosmetic through a fixed pressing hole. This inversion of the operational principle enables single-handed use while keeping the container body stationary, simplifying the overall operational mechanism.
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 solution enables single-handed operation, reduces material waste, and prevents pollution by ensuring unidirectional discharge, simplifying the structure and lowering manufacturing costs.
Implementation Method 1
