Rotating Cosmetic Discharge Structure for Hygienic Controlled Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers suffer from contamination and operational defects during use, leading to skin troubles and inefficient cosmetic usage due to exposure to external substances and unstable discharge mechanisms.
Innovation Solution
A rotating discharge-type cosmetic container design featuring a rotary operation member that rotates in conjunction with a rotary member, ensuring stable contact and smooth discharge, with a cutting blade and passage hole for controlled cosmetic release, and a refillable structure to minimize waste and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid of the cosmetic container is opened to access the cosmetic content, then the cosmetic can be easily accessed and applied, but the cosmetic is completely exposed to the air and easily contaminated by external foreign substances and bacteria
Solution Approach 1:
The container is divided into an inner container and an outer container that can be separated. The inner container can be removed from the outer container, allowing the cosmetic content to be accessed without opening the lid completely. This segmentation enables controlled access while maintaining protection against contamination.
Solution Approach 2:
The inner container acts as an intermediary between the user and the cosmetic content. Instead of directly exposing the cosmetic to the environment through lid opening, the inner container can be removed as an intermediate step, providing a controlled interface that reduces direct exposure to contaminants.
2Duration of action of moving object
If a puff is repeatedly used while coming into contact with the cosmetic, then the cosmetic can be applied multiple times, but the cosmetic is contaminated by bacteria, viruses, and molds, causing skin troubles and shortening the period of use
Solution Approach 1:
The inner container can be completely removed from the outer container, allowing the cosmetic content to be extracted and applied without the need to repeatedly open and close the lid. This reduces the number of times the cosmetic is exposed to the environment and contaminated by bacteria from the puff.
Solution Approach 2:
The inner container is pre-positioned within the outer container, ready for removal and use. This preliminary arrangement allows the cosmetic to be accessed and applied without repeated lid opening, preventing contamination before it occurs.
3Ease of operation
If the conventional cosmetic container is used by taking out cosmetics with a cosmetic tool, then the cosmetic can be applied, but the amount of cosmetics used is not constantly adjusted, resulting in waste and inconvenience
Solution Approach 1:
The container structure allows the inner container to be easily removed and replaced when empty, enabling the user to refill or replace the cosmetic content without complex mechanisms. This self-service approach ensures constant adjustment of cosmetic availability and reduces waste by allowing timely replacement.
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 design allows for stable, smooth, and controlled discharge of cosmetic content, reducing operational costs and promoting hygiene by preventing bacterial contamination and reducing operational defects, and allows for easy cleaning and reducing operational defects.
